Solar Technology Quotes

I do not believe that all books will or should migrate onto screens: as Douglas Adams once pointed out to me, more than 20 years before the Kindle showed up, a physical book is like a shark. Sharks are old: there were sharks in the ocean before the dinosaurs. And the reason there are still sharks around is that sharks are better at being sharks than anything else is. Physical books are tough, hard to destroy, bath-resistant, solar-operated, feel good in your hand: they are good at being books, and there wil always be a place for them.

I would love to believe that when I die I will live again, that some thinking, feeling, remembering part of me will continue. But as much as I want to believe that, and despite the ancient and worldwide cultural traditions that assert an afterlife, I know of nothing to suggest that it is more than wishful thinking. I want to grow really old with my wife, Annie, whom I dearly love. I want to see my younger children grow up and to play a role in their character and intellectual development. I want to meet still unconceived grandchildren. There are scientific problems whose outcomes I long to witness—such as the exploration of many of the worlds in our Solar System and the search for life elsewhere. I want to learn how major trends in human history, both hopeful and worrisome, work themselves out: the dangers and promise of our technology, say; the emancipation of women; the growing political, economic, and technological ascendancy of China; interstellar flight. If there were life after death, I might, no matter when I die, satisfy most of these deep curiosities and longings. But if death is nothing more than an endless dreamless sleep, this is a forlorn hope. Maybe this perspective has given me a little extra motivation to stay alive. The world is so exquisite, with so much love and moral depth, that there is no reason to deceive ourselves with pretty stories for which there's little good evidence. Far better, it seems to me, in our vulnerability, is to look Death in the eye and to be grateful every day for the brief but magnificent opportunity that life provides.

Each Voyager is itself a message. In their exploratory intent, in the lofty ambition of their objectives, in their utter lack of intent to do harm, and in the brilliance of their design and performance, these robots speak eloquently for us.

Even with all the technology, information, and communications that they had, it still came down to men and women in frail boats doing hard, dirty work over long hours in an environment that would kill them if they weren’t both careful and lucky.

Radical space technologies never reach the public because unknown groups do not wish humanity to have access to the highest knowledge or the most advanced scientific inventions. Perhaps this suppression is out of fear that the masses may be able to explore our Solar System and the Universe beyond it. Whatever the case, it seems they want us to stay at ignorant levels forever.

The explosive development of technology was analogous to the grown of cancer cells, and the results would be identical: the exhaustion of all sources of nourishment, the destruction of organs, and the final death of the host body. He advocated abolishing crude technologies such as fossil fuels and nuclear energy and keeping gentler technologies such as solar power and small-scale hydroelectric power.

I find these comparisons particularly poignant: life versus death, hope versus fear. Space exploration and the highly mechanized destruction of people use similar technology and manufacturers, and similar human qualities of organization and daring. Can we not make the transition from automated aerospace killing to automated aerospace exploration of the solar system in which we live?

If you didn’t already know this, the sun is going to die. When I think about the future, I don’t think about inescapable ends. But even if we solve global warming and destroy nuclear bombs and control population, ultimately the human race will annihilate itself if we stay here. Eventually, inevitably, we will no longer be able to live on Earth: we have a giant fireball clock ticking down twilight by twilight. In many ways, I think mortality is more manageable when we consider our eternal components, our genetics and otherwise that carry on after us. Still, soon enough, the books we write and the plants we grow will freeze up and rot in the darkness. But maybe there’s hope. What the universe really boils down to is whether a planet evolves a life-form intelligent enough to create technology capable of transporting and sustaining that life-form off the planet before the sun in that planet’s solar system explodes. I have a limited set of comparative data points, but I’d estimate that we’re actually doing okay at this point. We already have (intelligent) life, technology, and (primitive) space travel. And we still have some time before our sun runs out of hydrogen and goes nuclear. Yet none of that matters unless we can develop a sustainable means of living and traveling in space. Maybe we can. What I’ve concluded is that if we do reach this point, we have crossed a remarkable threshold—and will emerge into the (rare?) evolutionary status of having outlived the very life source that created us. It’s natural selection on a Universal scale. “The Origin of the Aliens,” one could say; a survival of the fittest planets. Planets capable of evolving life intelligent enough to leave before the lights go out. I suppose that without a God, NASA is my anti-nihilism. Alone and on my laptop, these ideas can humble me into apathy.

Fracking—to take one example—was not the brainchild of private-sector research but the fruit of research paid for twenty years ago by the DOE. Yet fracking has collapsed the price of oil and gas and led to American energy independence. Solar and wind technologies are another example. The

A more ambitious bet would be to learn from what we imagine a more mature civilization might have attempted. To take the small scientific leap and allow the possibility ‘Oumuamua was extraterrestrial technology is to give humanity the small nudge toward thinking like a civilization that could have left a lightsail buoy for our solar system to run into. It is to nudge us not just to imagine alien spacecraft but to contemplate the construction of our own such craft.

Nuclear had proliferated before it was safe, and there were accidents. Solar had proliferated before it was efficient, and people lost money. Both technologies got bad reputations and withered on the vine.

we will look ahead to a time when we will be able to move beyond the solar system and explore the nearby stars. Again, this mission surpasses our current technology, but fifth wave technologies will make it possible: nanoships, laser sails, ramjet fusion machines, antimatter engines.

The eyes have been used to signify a perverse capacity - honed to perfection in the history of science tied to militarism, capitalism, colonialism, and male supremacy - to distance the knowing subject from everybody and everything in the interests of unfettered power. The instruments of visualization in multinationalist, postmodernist culture have compounded these meanings of dis-embodiment. The visualizing technologies are without apparent limit; the eye of any ordinary primate like us can be endlessly enhanced by sonography systems, magnetic resonance imaging, artificial intelligence-linked graphic manipulation systems, scanning electron microscopes, computer-aided tomography scanners, colour enhancement techniques, satellite surveillance systems, home and office VDTs, cameras for every purpose from filming the mucous membrane lining the gut cavity of a marine worm living in the vent gases on a fault between continental plates to mapping a planetary hemisphere elsewhere in the solar system. Vision in this technological feast becomes unregulated gluttony; all perspective gives way to infinitely mobile vision, which no longer seems just mythically about the god-trick of seeing everything from nowhere, but to have put the myth into ordinary practice. And like the god-trick, this eye fucks the world to make techno-monsters. Zoe Sofoulis (1988) calls this the cannibal-eye of masculinist extra-terrestrial projects for excremental second birthing.

It is conventional wisdom now that anything built by the government will be a disaster. But the two "Voyager" spacecraft were built by the government (in partnership with that other bugaboo, academia). They came in at cost, on time, and vastly exceeded their design specifications--as well as the fondest dreams of their makers. Seeking not to control, threaten, wound, or destroy, these elegant machines represented the exploratory part of our nature set free to roam the Solar System and beyond. This kind of technology, the treasures it uncovers freely available to all humans everywhere, has been, over the last few decades, one of the few activities of the United States admired as much by those who abhor many of its policies as by those who agree with it on every issue. "Voyager" cost each American less than a penny a year from launch to Neptune encounter. Missions to the planets are one of those things--and I mean this not just for the United States, but for the human species--that we do best.

One way or another, I regard it as almost inevitable that either a nuclear confrontation or environmental catastrophe will cripple the Earth at some point in the next 1,000 years which, as geological time goes, is the mere blink of an eye. By then I hope and believe that our ingenious race will have found a way to slip the surly bonds of Earth and will therefore survive the disaster. The same of course may not be possible for the millions of other species that inhabit the Earth, and that will be on our conscience as a race. I think we are acting with reckless indifference to our future on planet Earth. At the moment, we have nowhere else to go, but in the long run the human race shouldn’t have all its eggs in one basket, or on one planet. I just hope we can avoid dropping the basket before we learn how to escape from Earth. But we are, by nature, explorers. Motivated by curiosity. This is a uniquely human quality. It is this driven curiosity that sent explorers to prove the Earth is not flat and it is the same instinct that sends us to the stars at the speed of thought, urging us to go there in reality. And whenever we make a great new leap, such as the Moon landings, we elevate humanity, bring people and nations together, usher in new discoveries and new technologies. To leave Earth demands a concerted global approach—everyone should join in. We need to rekindle the excitement of the early days of space travel in the 1960s. The technology is almost within our grasp. It is time to explore other solar systems. Spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth. If we stay, we risk being annihilated.

If evidence of extraterrestrial life appeared in our solar system, would we notice? If we are expecting the bang of gravity-defying ships on the horizon, do we risk missing the subtle sound of other arrivals? What if, for instance, that evidence was inert or defunct technology- the equivalent, perhaps, of a billion-year-old civilization's trash?

In part 2, we will look ahead to a time when we will be able to move beyond the solar system and explore the nearby stars. Again, this mission surpasses our current technology, but fifth wave technologies will make it possible: nanoships, laser sails, ramjet fusion machines, antimatter engines. Already, NASA has funded studies on the physics necessary to make interstellar travel a reality.

Only in the last 200 years have we become dependent on nonrenewable minerals. Modern industry runs on the scarcest of the available forms of low entropy. Traditional technology (windmills, waterwheels, etc.) runs on the more abundant solar source. How ironic, therefore, to be told by technological optimists that modern technology is freeing man from dependence on resources (Barnett and Morse, 1963, p. 11). The very opposite is true.

When contemplating humanity’s potential future technologies and their use and effect on our world, we should bear in mind that the coming mutation will directly affect the way we think. Since our primary awareness is shifting to the solar plexus area, all future insights and breakthroughs in science will come from this awareness rather than from our logical mind. This will entirely change scientific approach. Instead of beginning with doubt and then working to resolve that doubt through scientific method, we will begin with certainty and use logic to confirm and deepen that certainty. This will give birth to a new era of science and technology, and the future science will be a science of synthesis. Science will work hand in hand with art, music, mythology, and psychology and, of particular importance, it will be rooted in the physical structure and understanding of the body.

Musk’s insistence on explaining the early origins of his passion for electric cars, solar energy, and rockets can come off as insecure. It feels as if Musk is trying to shape his life story in a forced way. But for Musk, the distinction between stumbling into something and having intent is important. Musk has long wanted the world to know that he’s different from the run-of-the-mill entrepreneur in Silicon Valley. He wasn’t just sniffing out trends, and he wasn’t consumed by the idea of getting rich. He’s been in pursuit of a master plan all along. “I really was thinking about this stuff in college,” he said. “It is not some invented story after the fact. I don’t want to seem like a Johnny-come-lately or that I’m chasing a fad or just being opportunistic. I’m not an investor. I like to make technologies real that I think are important for the future and useful in some sort of way.

From the beginning, man could look up at a vast universe dotted by innumerable stars to find every evidence that he was nothing. This evidence only grows stronger as science and technology record an expanse of galaxies filled with planetary solar systems beyond any visible end. Man is but a grain of sand lost on an endless seashore, and yet he believes with conviction in his own greatness.  He is either a divine soul intuitively aware of his inherent, limitless potential—or he is a blind fool.

The question today, then, is whether the world's populations are not close to having done with soft sciences and technologies, which still take into account the preservation of the planet and its inhabitants; whether they are not now in danger of being swept away by the terrorist excesses of a Laputian ratio, a universal philanoia attacking a human species which has become 'undesirable' in its entirety, the scandal of an Earth which is, so far as we know, the only biosphere in the solar system.

The age of centralized, command-and-control, extraction-resource-based energy sources (oil, gas, coal and nuclear) will not end because we run out of petroleum, natural gas, coal, or uranium. It will end because these energy sources, the business models they employ, and the products that sustain them will be disrupted by superior technologies, product architectures, and business models. Compelling new technologies such as solar, wind, electric vehicles, and autonomous (self-driving) cars will disrupt and sweep away the energy industry as we know it.

And this is one of the first things one learns from Musk’s example—he is relentless in his pursuit of the bold and, the bigger point, totally unfazed by scale. When he couldn’t get a job, he started a company. When Internet commerce stalled, he reinvented banking. When he couldn’t find decent launch services for his Martian greenhouse, he went into the rocket business. And as a kicker, because he never lost interest in the problem of energy, he started both an electric car and a solar energy company. It is also worth pointing out that Tesla is the first successful car company started in America in five decades and that SolarCity has become one of the nation’s largest residential solar providers.9 All told, in slightly less than a dozen years, Musk’s appetite for bold has created an empire worth about $30 billion.10 So what’s his secret? Musk has a few, but none are more important to him than passion and purpose. “I didn’t go into the rocket business, the car business, or the solar business thinking this is a great opportunity. I just thought, in order to make a difference, something needed to be done. I wanted to have an impact. I wanted to create something substantially better than what came before.

By the early twenty-second century, the technology for self-replicating robots should be perfected, and we may be able to entrust machines with the task of constructing solar arrays and laser batteries on the moon, Mars, and beyond. We would ship over an initial team of automatons, some of which would mine the regolith and others of which would build a factory. Another set of robots would oversee the sorting, milling, and smelting of raw materials in the factory to separate and obtain various metals. These purified metals could then be used to assemble laser launch stations—and a new batch of self-replicating robots. We might eventually have a bustling network of relay stations throughout the solar system, perhaps stretching from the moon all the way to the Oort Cloud. Because the comets in the Oort Cloud extend roughly halfway to Alpha Centauri and are largely stationary, they may be ideal locations for laser banks that could provide an extra boost to nanoships on their journey to our neighboring star system. As each nanoship passed by one of these relay stations, its lasers would fire automatically and give the ship an added push to the stars. Self-replicating robots could build these distant outposts by using fusion instead of sunlight as the basic source of energy.

He believed that technological progress was a disease in human society. The explosive development of technology was analogous to the growth of cancer cells, and the results would be identical: the exhaustion of all sources of nourishment, the destruction of organs, and the final death of the host body. He advocated abolishing crude technologies such as fossil fuels and nuclear energy and keeping gentler technologies such as solar power and small-scale hydroelectric power. He believed in the gradual de-urbanization of modern metropolises by distributing the population more evenly in self-sufficient small towns and villages. Relying on the gentler technologies, he would build a new agricultural society.

We’ve seen what happens with the development of the cell-phone technology that was deployed in Africa faster than any other technology ever in the history of humanity. We see small villages, where they have no running water, wood fires to cook with, and no electricity — yet there’s one little solar panel on top of a mud hut and that solar panel is not there for light. It’s there to charge a Nokia 1000 feature phone. That phone gives them weather reports, grain prices at the local market, and connects them to the world. What happens when that phone becomes a bank? Because with bitcoin, it can be a bank. What happens when you connect 6 1/2 billion people to a global economy without any barriers to access? ​ ​

Moore’s law means computers will get smaller, more powerful, and cheaper at a reliable rate. This does not happen because Moore’s law is a natural law of the physical world, like gravity, or the Second Law of Thermodynamics. It happens because the consumer and business markets motivate computer chip makers to compete and contribute to smaller, faster, cheaper computers, smart phones, cameras, printers, solar arrays, and soon, 3-D printers. And chip makers are building on the technologies and techniques of the past. In 1971, 2,300 transistors could be printed on a chip. Forty years, or twenty doublings later, 2,600,000,000. And with those transistors, more than two million of which could fit on the period at the end of this sentence, came increased speed.

Based on these two successes, Pan’s opinions on social issues had grown more and more influential. He believed that technological progress was a disease in human society. The explosive development of technology was analogous to the growth of cancer cells, and the results would be identical: the exhaustion of all sources of nourishment, the destruction of organs, and the final death of the host body. He advocated abolishing crude technologies such as fossil fuels and nuclear energy and keeping gentler technologies such as solar power and small-scale hydroelectric power. He believed in the gradual de-urbanization of modern metropolises by distributing the population more evenly in self-sufficient small towns and villages. Relying on the gentler technologies, he would build a new agricultural society.

RENEWABLE ENERGY REVOLUTION: SOLAR + WIND + BATTERIES In addition to AI, we are on the cusp of another important technological revolution—renewable energy. Together, solar photovoltaic, wind power, and lithium-ion battery storage technologies will create the capability of replacing most if not all of our energy infrastructure with renewable clean energy. By 2041, much of the developed world and some developing countries will be primarily powered by solar and wind. The cost of solar energy dropped 82 percent from 2010 to 2020, while the cost of wind energy dropped 46 percent. Solar and onshore wind are now the cheapest sources of electricity. In addition, lithium-ion battery storage cost has dropped 87 percent from 2010 to 2020. It will drop further thanks to the massive production of batteries for electrical vehicles. This rapid drop in the price of battery storage will make it possible to store the solar/wind energy from sunny and windy days for future use. Think tank RethinkX estimates that with a $2 trillion investment through 2030, the cost of energy in the United States will drop to 3 cents per kilowatt-hour, less than one-quarter of today’s cost. By 2041, it should be even lower, as the prices of these three components continue to descend. What happens on days when a given area’s battery energy storage is full—will any generated energy left unused be wasted? RethinkX predicts that these circumstances will create a new class of energy called “super power” at essentially zero cost, usually during the sunniest or most windy days. With intelligent scheduling, this “super power” can be used for non-time-sensitive applications such as charging batteries of idle cars, water desalination and treatment, waste recycling, metal refining, carbon removal, blockchain consensus algorithms, AI drug discovery, and manufacturing activities whose costs are energy-driven. Such a system would not only dramatically decrease energy cost, but also power new applications and inventions that were previously too expensive to pursue. As the cost of energy plummets, the cost of water, materials, manufacturing, computation, and anything that has a major energy component will drop, too. The solar + wind + batteries approach to new energy will also be 100-percent clean energy. Switching to this form of energy can eliminate more than 50 percent of all greenhouse gas emissions, which is by far the largest culprit of climate change.

Whole Earth Discipline carries on something that began in 1968, when I founded the Whole Earth Catalog. I stayed with the Catalog as editor and publisher until 1984, adding a magazine called CoEvolution Quarterly along the way. The Whole Earth publications were compendia of environmentalist tools and skills (along with much else) and explicitly purveyed a biological way of understanding. Peter Warshall wrote and reviewed about watersheds, soil, and ecology. Richard Nilsen and Rosemary Menninger covered organic farming and community gardens. J. Baldwin was an impeccable source on “appropriate technology”—solar, wind, insulation, bicycles. Lloyd Kahn wrote about handmade houses. We promoted bioregionalism, restoration, and “reinhabitation” of one’s natural environment. There’s now an insightful book about all that by Andrew Kirk—Counterculture Green: The Whole Earth Catalog and American Environmentalism (2007).

I think we are acting with reckless indifference to our future on planet Earth. At the moment, we have nowhere else to go, but in the long run the human race shouldn’t have all its eggs in one basket, or on one planet. I just hope we can avoid dropping the basket before we learn how to escape from Earth. But we are, by nature, explorers. Motivated by curiosity. This is a uniquely human quality.

If we stay, we risk being annihilated.

You don’t need to pity them. Really, let me tell you: don’t. The reality of the universe is not something to envy.” “Why?” Yifan lifted a hand and pointed at the stars of the galaxy. Then he let the 3G force pull his arm back to this chest. “Darkness. Only darkness.” “You mean the dark forest state?” Guan Yifan shook his head, a gesture that appeared to be a struggle in hypergravity. “For us, the dark forest state is all-important, but it’s just a detail of the cosmos. If you think of the cosmos as a great battlefield, dark forest strikes are nothing more than snipers shooting at the careless—messengers, mess men, etc. In the grand scheme of the battle, they are nothing. You have not seen what a true interstellar war is like.” “Have you?” “We’ve caught a few glimpses. But most things we know are just guesses.… Do you really want to know? The more you possess of this kind of knowledge, the less light remains in your heart.” “My heart is already completely dark. I want to know.” And so, more than six centuries after Luo Ji had fallen through ice into that lake, another dark veil hiding the truth about the universe was lifted before the gaze of one of the only survivors of Earth civilization. Yifan asked, “Why don’t you tell me what the most powerful weapon for a civilization possessing almost infinite technological prowess is? Don’t think of this as a technical question. Think philosophy.” Cheng Xin pondered for a while and then struggled to shake her head. “I don’t know.” “Your experiences should give you a hint.” What had she experienced? She had seen how a cruel attacker could lower the dimensions of space by one and destroy a solar system. What are dimensions? “The universal laws of physics,” Cheng Xin said. “That’s right. The universal laws of physics are the most terrifying weapons, and also the most effective defenses. Whether it’s by the Milky Way or the Andromeda Galaxy, at the scale of the local galactic group or the Virgo Supercluster, those warring civilizations possessing godlike technology will not hesitate to use the universal laws of physics as weapons. There are many laws that can be manipulated into weapons, but most commonly, the focus is on spatial dimensions and the speed of light. Typically, lowering spatial dimensions is a technique for attack, and lowering the speed of light is a technique for defense. Thus, the dimensional strike on the Solar System was an advanced attack method. A dimensional strike is a sign of respect. In this universe, respect is not easy to earn. I guess you could consider it an honor for Earth civilization.

It appears that during the early years of the solar system Venus was only slightly warmer than Earth and probably had oceans. But those few degrees of extra warmth meant that Venus could not hold on to its surface water, with disastrous consequences for its climate. As its water evaporated, the hydrogen atoms escaped into space, and the oxygen atoms combined with carbon to form a dense atmosphere of the greenhouse gas CO2. Venus became stifling. Although people of my age will recall a time when astronomers hoped that Venus might harbor life beneath its padded clouds, possibly even a kind of tropical verdure, we now know that it is much too fierce an environment for any kind of life that we can reasonably conceive of. Its surface temperature is a roasting 470 degrees centigrade (roughly 900 degrees Fahrenheit), which is hot enough to melt lead, and the atmospheric pressure at the surface is ninety times that of Earth, or more than any human body could withstand. We lack the technology to make suits or even spaceships that would allow us to visit. Our knowledge of Venus’s surface is based on distant radar imagery and some startled squawks from an unmanned Soviet probe that was dropped hopefully into the clouds in 1972 and functioned for barely an hour before permanently shutting down.

Evolution is largely a temporal phenomenon, Merrill. The environment changes, and populations in that environment change in turn, or they languish. Individual organisms don't evolve; populations do. Nature doesn't give a damn about individuals. The only role we play in evolution is surviving long enough to give birth to offspring who are slightly different from us. Some of our offspring will prosper in a changing environment, and some of them will not. As for us individuals, once we've reproduced, nature has no more use for us. We perish along with our ill-adapted young. Death has always been an essential factor in species survival. Now consider the human race. We are a partial exception to the rule. Unlike other species, we have developed culture. Instead of adapting to a changing environment biologically, we can sometimes adapt to it culturally. If an Ice Age comes along, we don't need to grow fur on our bodies if we invent the fur coat. Culture allows us to adapt to almost any environment, including the harshest, like space. In fact, our cultural adaptation is so robust that it all but obviates the need to evolve biologically. We are so good at adapting to changing conditions with our knowledge and technology that we may deceive ourselves into believing that we are above nature. But only a fools believes that. Nature always has the last word. A star in our neighborhood could go supernova and wipe out all life in our solar system, and no amount of culture could save us from that. That, I believe, is the main reason you want to seed humanity throughout the galaxy. So as not to have all our eggs in one basket... The chief difference between biological and cultural adaptation is that while biological evolution doesn't care about individuals, cultural evolution does, often at the expense of the species. Look at how many times we've nearly wiped ourselves out through cultural means: the nuclear bomb, pollution, climate change, the Outrage. We can't seem to help ourselves. Look at what we've done: we've made individuals all but immortal, even when it means we can have no more children. In one stroke, we've eliminated the two key ingredients of evolution: offspring and death. From a biological perspective, we're skating on mighty thin ice. ... ...as long as the individual reigns supreme, there's a finite limit to our survival. ... We need a means for the individual, not just the species, to participate in biological evolution, and that's what my project is all about. We need to be able to let our biological bodies die, to have offspring that are molded by the changing needs of the environments we find ourselves in, and yet to serially inhabit these bodies as the same individual. That means we need to be able to move our minds from one body to the next. ... Mine is a singularity in which the obsolete individual is invited to cross over to the new, not simply to die out. The existing person need not die to make room for the newcomer. Anyone can play.

As I write this, I know there are countless mysteries about the future of business that we’ve yet to unravel. That’s a process that will never end. When it comes to customer success, however, I have achieved absolute clarity on four points. First, technology will never stop evolving. In the years to come, machine learning and artificial intelligence will probably make or break your business. Success will involve using these tools to understand your customers like never before so that you can deliver more intelligent, personalized experiences. The second point is this: We’ve never had a better set of tools to help meet every possible standard of success, whether it’s finding a better way to match investment opportunities with interested clients, or making customers feel thrilled about the experience of renovating their home. The third point is that customer success depends on every stakeholder. By that I mean employees who feel engaged and responsible and are growing their careers in an environment that allows them to do their best work—and this applies to all employees, from the interns to the CEO. The same goes for partners working to design and implement customer solutions, as well as our communities, which provide the schools, hospitals, parks, and other facilities to support us all. The fourth and most important point is this: The gap between what customers really want from businesses and what’s actually possible is vanishing rapidly. And that’s going to change everything. The future isn’t about learning to be better at doing what we already do, it’s about how far we can stretch the boundaries of our imagination. The ability to produce success stories that weren’t possible a few years ago, to help customers thrive in dramatic new ways—that is going to become a driver of growth for any successful company. I believe we’re entering a new age in which customers will increasingly expect miracles from you. If you don’t value putting the customer at the center of everything you do, then you are going to fall behind. Whether you make cars, solar panels, television programs, or anything else, untold opportunities exist. Every company should invest in helping its customers find new destinations, and in blazing new trails to reach them. To do so, we have to resist the urge to make quick, marginal improvements and spend more time listening deeply to what customers really want, even if they’re not fully aware of it yet. In the end, it’s a matter of accepting that your success is inextricably linked to theirs.

Space is nearly empty. There is virtually no chance that one of the Voyagers will ever enter another solar system—and this is true even if every star in the sky is accompanied by planets. The instructions on the record jackets, written in what we believe to be readily comprehensible scientific hieroglyphics, can be read, and the contents of the records understood, only if alien beings, somewhere in the remote future, find Voyager in the depths of interstellar space. Since both Voyagers will circle the center of the Milky Way Galaxy essentially forever, there is plenty of time for the records to be found—if there's anyone out there to do the finding. We cannot know how much of the records they would understand. Surely the greetings will be incomprehensible, but their intent may not be. (We thought it would be impolite not to say hello.) The hypothetical aliens are bound to be very different from us—independently evolved on another world. Are we really sure they could understand anything at all of our message? Every time I feel these concerns stirring, though, I reassure myself. Whatever the incomprehensibilities of the Voyager record, any alien ship that finds it will have another standard by which to judge us. Each Voyager is itself a message. In their exploratory intent, in the lofty ambition of their objectives, in their utter lack of intent to do harm, and in the brilliance of their design and performance, these robots speak eloquently for us. But being much more advanced scientists and engineers than we—otherwise they would never be able to find and retrieve the small, silent spacecraft in interstellar space—perhaps the aliens would have no difficulty understanding what is encoded on these golden records. Perhaps they would recognize the tentativeness of our society, the mismatch between our technology and our wisdom. Have we destroyed ourselves since launching Voyager, they might wonder, or have we gone on to greater things? Or perhaps the records will never be intercepted. Perhaps no one in five billion years will ever come upon them. Five billion years is a long time. In five billion years, all humans will have become extinct or evolved into other beings, none of our artifacts will have survived on Earth, the continents will have become unrecognizably altered or destroyed, and the evolution of the Sun will have burned the Earth to a crisp or reduced it to a whirl of atoms. Far from home, untouched by these remote events, the Voyagers, bearing the memories of a world that is no more, will fly on.

Today, multiple major waves seem to be arriving simultaneously—technologies like the cloud, AI, AR/ VR, not to mention more esoteric projects like supersonic planes and hyperloops. What’s more, rather than being concentrated narrowly in a personal computer industry that was essentially a niche market, today’s new technologies impact nearly every part of the economy, creating many new opportunities. This trend holds tremendous promise. Precision medicine will use computing power to revolutionize health care. Smart grids use software to dramatically improve power efficiency and enable the spread of renewable energy sources like solar roofs. And computational biology might allow us to improve life itself. Blitzscaling can help these advances spread and magnify their sorely needed impact.

So what’s his secret? Musk has a few, but none are more important to him than passion and purpose. “I didn’t go into the rocket business, the car business, or the solar business thinking this is a great opportunity. I just thought, in order to make a difference, something needed to be done. I wanted to have an impact. I wanted to create something substantially better than what came before.” Musk, like every entrepreneur in this chapter, is driven by passion and purpose. Why? Passion and purpose scale—always have, always will. Every movement, every revolution, is proof of this fact. Plus, doing anything big and bold is difficult, and at two in the morning for the fifth night in a row, when you need to keep going, you’re only going to fuel yourself from deep within. You’re not going to push ahead when it’s someone else’s mission. It needs to be yours.

Tesla is a vehicle for an idea: that we humans have better ways to power our lives than to burn a dinosaur-era compaction that dirties the air and skanks up the chemistry of the atmosphere. That notion applies to more than just cars. Tesla also sells its batteries as energy storage units. Since it acquired SolarCity in 2016 and added solar panels to its offerings, Musk has made his intentions clear: Tesla is an energy company. This is the story of how the electric car became a Trojan horse for a new energy economy. I believe it is the most important technology story of the twenty-first century.

The apparent incompatibility between the abundance of habitable planets in our Galaxy and the lack of extraterrestrial visitors, known as the Fermi paradox, suggest the existence of what Hanson calls a "Great Filter," an evolutionary/technological roadblock somewhere along the developmental path from nonliving matter to space-colonizing life. If we discover independently evolved primitive life in our Solar System, this would suggest that primitive life is not rare, and that the roadblock lies after our current human stage of development-perhaps because assumption 1 is false, or because almost all advanced civilizations self-destruct before they are able to colonize. I'm therefore crossing my fingers that all searches for life on Mars and elsewhere find nothing: this is consistent with the scenario where primitive life is rare but we humans got lucky, so that we have the roadblock behind us and have extraordinary future potential.

To do so, we first have to learn to see it for what it is—by cutting through all of the buzzwords, the marketing hype, the pseudoscientific shibboleths and mumbo-jumbo. Then we have to learn to evaluate it: if it is efficient, then by what measure, and who stands to benefit from its efficiency? Efficiency as a euphemism for corporate profitability shouldn’t fool us. Efficiency is a measure that relates productivity (output) to labor and resource inputs; it is meaningless unless we understand all the implications of these inputs and outputs. For a solar panel, does it simply input solar radiation and output electric current? No, its input is all the energy—mainly from fossil fuels—that went into mining, refining, fabricating, finance, design, research, sales, shipping, installation, tech support, maintenance and disposal. Its output is, yes, a modest amount of electricity. It could well turn out that your solar panel is a way to convert a lot of fossil fuel energy into a bit of electricity with the help of sunlight. How efficient is that? Perhaps it would be more efficient to use less electricity—or to not use electricity at all.

This book is a compilation of interesting ideas that have strongly influenced my thoughts and I want to share them in a compressed form. That ideas can change your worldview and bring inspiration and the excitement of discovering something new. The emphasis is not on the technology because it is constantly changing. It is much more difficult to change the accompanying circumstances that affect the way technological solutions are realized. The chef did not invent salt, pepper and other spices. He just chooses good ingredients and uses them skilfully, so others can enjoy his art. If I’ve been successful, the book creates a new perspective for which the selection of ingredients is important, as well as the way they are smoothly and efficiently arranged together. In the first part of the book, we follow the natural flow needed to create the stimulating environment necessary for the survival of a modern company. It begins with challenges that corporations are facing, changes they are, more or less successfully, trying to make, and the culture they are trying to establish. After that, we discuss how to be creative, as well as what to look for in the innovation process. The book continues with a chapter that talks about importance of inclusion and purpose. This idea of inclusion – across ages, genders, geographies, cultures, sexual orientation, and all the other areas in which new ways of thinking can manifest – is essential for solving new problems as well as integral in finding new solutions to old problems. Purpose motivates people for reaching their full potential. This is The second and third parts of the book describes the areas that are important to support what is expressed in the first part. A flexible organization is based on IT alignment with business strategy. As a result of acceleration in the rate of innovation and technological changes, markets evolve rapidly, products’ life cycles get shorter and innovation becomes the main source of competitive advantage. Business Process Management (BPM) goes from task-based automation, to process-based automation, so automating a number of tasks in a process, and then to functional automation across multiple processes andeven moves towards automation at the business ecosystem level. Analytics brought us information and insight; AI turns that insight into superhuman knowledge and real-time action, unleashing new business models, new ways to build, dream, and experience the world, and new geniuses to advance humanity faster than ever before. Companies and industries are transforming our everyday experiences and the services we depend upon, from self-driving cars, to healthcare, to personal assistants. It is a central tenet for the disruptive changes of the 4th Industrial Revolution; a revolution that will likely challenge our ideas about what it means to be a human and just might be more transformative than any other industrial revolution we have seen yet. Another important disruptor is the blockchain - a distributed decentralized digital ledger of transactions with the promise of liberating information and making the economy more democratic. You no longer need to trust anyone but an algorithm. It brings reliability, transparency, and security to all manner of data exchanges: financial transactions, contractual and legal agreements, changes of ownership, and certifications. A quantum computer can simulate efficiently any physical process that occurs in Nature. Potential (long-term) applications include pharmaceuticals, solar power collection, efficient power transmission, catalysts for nitrogen fixation, carbon capture, etc. Perhaps we can build quantum algorithms for improving computational tasks within artificial intelligence, including sub-fields like machine learning. Perhaps a quantum deep learning network can be trained more efficiently, e.g. using a smaller training set. This is still in conceptual research domain.

Future destinations in our solar system neighborhood include potential probe missions to a few moons of Jupiter, Saturn, and Neptune -- mainly by virtue of them being possible candidates for life, with their large oceans buried beneath icy crusts, plus intense volcanic activity. But getting humans to explore these possibly habitable worlds is a big issue in space travel. The record for the fastest-ever human spaceflight was set by the Apollo 10 crew as they gravita­tionally slingshotted around the Moon on their way back to Earth in May 1969. They hit a top speed of 39,897 kilo­meters per hour (24,791 miles per hour); at that speed you could make it from New York to Sydney and back in under one hour. Although that sounds fast, we've since recorded un-crewed space probes reaching much higher speeds, with the crown currently held by NASA's Juno probe, which, when it entered orbit around Jupiter, was traveling at 266,000 kilometers per hour (165,000 miles per hour). To put this into perspective, it took the Apollo 10 mission four days to reach the Moon; Opportunity took eight months to get to Mars; and Juno took five years to reach Jupiter. The distances in our solar system with our current spaceflight technology make planning for long-term crewed explora­tion missions extremely difficult." "So, will we ever explore beyond the edge of the solar system itself? The NASA Voyager 1 and 2 spacecraft were launched back in 1977 with extended flyby missions to the outer gas giant planets of Jupiter and Saturn. Voyager 2 even had flyby encounters with Uranus and Neptune -- it's the only probe ever to have visited these two planets. "The detailed images you see of Uranus and Neptune were all taken by Voyager 2. Its final flyby of Neptune was in October 1989, and since then, it has been traveling ever farther from the Sun, to the far reaches of the solar sys­tem, communicating the properties of the space around it with Earth the entire time. In February 2019, Voyager 2 reported a massive drop off in the number of solar wind particles it was detecting and a huge jump in cosmic ray particles from outer space. At that point, it had finally left the solar system, forty-one years and five months after being launched from Earth. "Voyager 1 was the first craft to leave the solar system in August 2012, and it is now the most distant synthetic object from Earth at roughly 21.5 billion kilometers (13.5 billion miles) away. Voyager 2 is ever so slightly closer to us at 18 billion kilometers (11 billion miles) away. Although we may ultimately lose contact with the Voyager probes, they will continue to move ever farther away from the Sun with nothing to slow them down or impede them. For this reason, both Voyager crafts carry a recording of sounds from Earth, including greetings in fifty-five differ­ent languages, music styles from around the world, and sounds from nature -- just in case intelligent life forms happen upon the probes in the far distant future when the future of humanity is unknown.

their lifetime is 30 years, then we need to sustainably produce wind turbine generation capacity at 133 GW per year. That is only a little more than two doublings from our current 25 GW, and a production rate we would hit in 2029 if the current industry growth rate of 19% is sustained. If we assume all solar technology lasts 20 years, we need a production rate of 200 GW per year, a rate that we would hit in 2027 if we maintain current growth rates. Once we hit those maintenance levels of production, the industries won’t need to grow any more; they just need to continue to produce at that level to sustain the output required for global clean energy.

Either way, in such vital sector related to the global challenge of climate change, collaboration would be more useful than trade wars.

I am concerned about the expansion of the solar industry in 2022, given that I was reporting extensive problems with the toxic technology to OSHA back in 2009.

Fossil fuels and electrical energy are global commodities which are primarily controlled by Monopolies and Cartels.

In 2016, ten additional countries were added to the OPEC cartel to form OPEC+. These countries are Azerbaijan, Bahrain, Brunei, Kazakhstan, Malaysia, Mexico, Oman, Russia, South Sudan, and Sudan. Make no mistake. The OPEC+ Cartel was formed to exert even more monopolistic control over global fossil fuels production supply and pricing. OPEC+ now directly controls well over 80% of the world’s proven oil reserves. Therefore, every consumer in the world is subjugated to whatever prices and production OPEC+ dictate.

Entrepreneurial innovation comes in three flavors: 1) new business models, as with Rent the Runway offering apparel for rent rather than sale; 2) new technologies, as with Solyndra, a failed maker of cylindrical solar panels built with a proprietary thin-film material; and 3) combining existing technologies in new ways, as with Quincy Apparel using a measurement system akin to that used for men’s suiting to offer better-fitting clothing for women.

solar power could be a technology of repair, social as well as environmental.

Still, there is one sense in which I am less grim than in my younger days. This book ends with the conviction that resistance to these dangers is at least possible. Some of that conviction stems from human ingenuity—watching the rapid spread of a technology as world-changing as the solar panel cheers me daily. And much of that conviction rests on events in my own life over the past few decades. I’ve immersed myself in movements working for change, and I helped found a group, 350.org, that grew into the first planetwide climate campaign. Though we haven’t beaten the fossil fuel industry, we’ve organized demonstrations in every country on the globe save North Korea, and with our many colleagues around the world, we’ve won some battles.

It is fair to say the attendees of the carnival-like conference just outside Miami took little note of McNabb’s consternation. Investors have in recent years been able to buy niche, “thematic” ETFs that purport to benefit from—deep breath—the global obesity epidemic; online gaming; the rise of millennials; the whiskey industry; robotics; artificial intelligence; clean energy; solar energy; autonomous driving; uranium mining; better female board representation; cloud computing; genomics technology; social media; marijuana farming; toll roads in the developing world; water purification; reverse-weighted US stocks; health and fitness; organic food; elderly care; lithium batteries; drones; and cybersecurity. There was even briefly an ETF that invested in the stocks of companies exposed to the ETF industry. Some of these more experimental funds gain traction, but many languish and are eventually liquidated, the money recycled into the latest hot fad.

During NASA’s first fifty years the agency’s accomplishments were admired globally. Democratic and Republican leaders were generally bipartisan on the future of American spaceflight. The blueprint for the twenty-first century called for sustaining the International Space Station and its fifteen-nation partnership until at least 2020, and for building the space shuttle’s heavy-lift rocket and deep spacecraft successor to enable astronauts to fly beyond the friendly confines of low earth orbit for the first time since Apollo. That deep space ship would fly them again around the moon, then farther out to our solar system’s LaGrange points, and then deeper into space for rendezvous with asteroids and comets, learning how to deal with radiation and other deep space hazards before reaching for Mars or landings on Saturn’s moons. It was the clearest, most reasonable and best cost-achievable goal that NASA had been given since President John F. Kennedy’s historic decision to land astronauts on the lunar surface. Then Barack Obama was elected president. The promising new chief executive gave NASA short shrift, turning the agency’s future over to middle-level bureaucrats with no dreams or vision, bent on slashing existing human spaceflight plans that had their genesis in the Kennedy, Johnson, Nixon, Ford, Carter, Reagan, Bush, Clinton, and Bush White Houses. From the starting gate, Mr. Obama’s uncaring space team rolled the dice. First they set up a presidential commission designed to find without question we couldn’t afford the already-established spaceflight plans. Thirty to sixty thousand highly skilled jobs went on the chopping block with space towns coast to coast facing 12 percent unemployment. $9.4 billion already spent on heavy-lift rockets and deep space ships was unashamedly flushed down America’s toilet. The fifty-year dream of new frontiers was replaced with the shortsighted obligations of party politics. As 2011 dawned, NASA, one of America’s great science agencies, was effectively defunct. While Congress has so far prohibited the total cancellation of the space agency’s plans to once again fly astronauts beyond low earth orbit, Obama space operatives have systematically used bureaucratic tricks to slow roll them to a crawl. Congress holds the purse strings and spent most of 2010 saying, “Wait just a minute.” Thousands of highly skilled jobs across the economic spectrum have been lost while hundreds of billions in “stimulus” have been spent. As of this writing only Congress can stop the NASA killing. Florida’s senior U.S. Senator Bill Nelson, a Democrat, a former spaceflyer himself, is leading the fight to keep Obama space advisors from walking away from fifty years of national investment, from throwing the final spade of dirt on the memory of some of America’s most admired heroes. Congressional committees have heard from expert after expert that Mr. Obama’s proposal would be devastating. Placing America’s future in space in the hands of the Russians and inexperienced commercial operatives is foolhardy. Space legend John Glenn, a retired Democratic Senator from Ohio, told president Obama that “Retiring the space shuttles before the country has another space ship is folly. It could leave Americans stranded on the International Space Station with only a Russian spacecraft, if working, to get them off.” And Neil Armstrong testified before the Senate’s Commerce, Science & Transportation Committee that “With regard to President Obama’s 2010 plan, I have yet to find a person in NASA, the Defense Department, the Air Force, the National Academies, industry, or academia that had any knowledge of the plan prior to its announcement. Rumors abound that neither the NASA Administrator nor the President’s Science and Technology Advisor were knowledgeable about the plan. Lack of review normally guarantees that there will be overlooked requirements and unwelcome consequences. How could such a chain of events happen?

Going Public Per my recent comments, I am increasingly concerned about SpaceX going public before the Mars transport system is in place. Creating the technology needed to establish life on Mars is and always has been the fundamental goal of SpaceX. If being a public company diminishes that likelihood, then we should not do so until Mars is secure. This is something that I am open to reconsidering, but, given my experiences with Tesla and SolarCity, I am hesitant to foist being public on SpaceX, especially given the long term nature of our mission. Some at SpaceX who have not been through a public company experience may think that being public is desirable. This is not so. Public company stocks, particularly if big step changes in technology are involved, go through extreme volatility, both for reasons of internal execution and for reasons that have nothing to do with anything except the economy. This causes people to be distracted by the manic-depressive nature of the stock instead of creating great products. For those who are under the impression that they are so clever that they can outsmart public market investors and would sell SpaceX stock at the “right time,” let me relieve you of any such notion. If you really are better than most hedge fund managers, then there is no need to worry about the value of your SpaceX stock, as you can just invest in other public company stocks and make billions of dollars in the market.

Arguably, the era’s most disruptive technology is the solar panel. Its price has dropped ninety-nine per cent in the past four decades, and roughly seventy-five per cent in the past six years; it now produces power nearly as cheaply as coal or gas, a condition that energy experts refer to as “grid parity.

The black expanse over our heads promise places where our industries can use resource extraction, zero-gravity manufacturing, better communications, perhaps even energy harvested in great solar farms and sent down to Earth. Companies are already planning to do so: Bigelow Aerospace (orbital hotels), Virgin Galactic (low Earth orbit tourism), Orbital Technologies (a commercial manufacturing space station), and Planetary Resources, whose goal is to develop a robotic asteroid mining industry.

Acclimatizing to its customs and particular brand of bustle, he’d gotten a sense of Wewoka. Without the lens of a fever-induced vision, it proved to be a dense, vertical city of narrow, terraced streets with expansive walkways. Largely devoid of motor traffic, any point could be reached by foot in fifteen minutes. Pictures painted on the sidewalks provided a colorful trail. With a central street lined with shops bustling with commerce, the noise and smell were different from what he was used to. Wewoka had none of the overworked smokestacks from innumerable factories; much of the city was made up by parks. The air had a hint of ozone to it. A collection of buildings sprouted at the heart of the city. Gleaming green and metallic spires in the distance, the sun reflected from their solar panels. A mushroom-like structure drew in sewer water from its “roots” and funneled it to its dome. Solar energy evaporated the water, which was then collected and released throughout the streets, watering the surrounding green spaces. Photovoltaic panels lined solar drop towers. Titanium dioxide reacted with ultraviolet rays and smog, filtering and dissipating them. They had developed similar technology in Jamaica. Vertical gardens and vegetation covered the steep towers of housing units and work offices. The exterior vertical gardens filtered the rain, which was reused with liquid wastes for farming needs. A deep calm reverberated through the city, quiet preserved like a commodity. Desmond

and it was surely the case also that only machines built to so large a scale and of such pristine alloys could bridge the span between heaven and earth with their song on our account and was she alone in these thoughts she wondered or did anyone else have similar feelings about these machines, this technology which of course they didn’t

Over the last year I’ve noticed that a surprising amount of Americans hate one or the other. I have a theory: solar panels and natural gas are totems. In anthropology, a “totem” is a symbol that serves as an emblem for a group of people. In our country, affiliation to one technology or the other quickly signifies your political tribe. In short, Republicans like things which explode and make loud noises (gas, petroleum, bombs) and Democrats like things which are techy, eco-friendly and generally don’t work very well (solar panels, wind power, automobiles powered by “hope”).

A half century after Nidetch’s Mallomar binges, scientists had developed a technology that could see cravings erupting, like solar flares, inside the human brain. In early 2008, a research team at the Lewis Center for Neuroimaging at the University of Oregon measured just such a craving in a nineteen-year-old college student we will call Debbie. Debbie had her head inside a very large, very expensive round magnet called an MRI scanner when an image of a chocolate milk shake was flashed before her eyes for two seconds. As soon as Debbie saw it, certain parts of her brain became “activated,” which is to say they drew in lots of blood as millions of neurons were fired. These regions—the left medial orbitofrontal cortex, anterior cingulate cortex, and three other small, curly pockets of gray matter—are all associated with “motivation.” And the functional MRI (fMRI) showed them glowing a bright yellowy orange, like coals in a hot fire, indicating those parts of her brain were churning through quite a lot of blood. She was experiencing “incentive salience,” the scientific term for a Frankenstein craving, or a heightened state of “wanting.” Debbie got what she wanted.

The cluster was oriented so that it was pointing toward the sun; that way, boiloff of the cryogenic propellants inside the tanks was reduced. Shadows of struts and attitude thrusters lay long against the sunlit white-and-silver bellies of the fuel tanks. The booster’s underside was illuminated only by the soft blue and green of Earthlight. She could see the great flaps of the cluster’s solar panels, folded up against the sides of the MS-IVB stage like wings; the panels would be unfurled when Ares was safely launched on its trajectory to Mars. There was the bold red UNITED STATES stenciled against the side of the MS-II, and the finer lettering along the long thin protective flaps masking the solar panels, and the NASA logo; and she could make out the support struts and attachment pins which held the External Tanks in place against the flanks of the MS-II, and the gold-gleaming mouths of the MS-II’s four J-2S engines, upgrades of the engines which had pushed Apollo to the Moon. To assemble this much mass in Earth orbit had taken all of nine Saturn VB flights over the last five years—half of them manned. The booster stages and their tanks had been flown up and assembled more or less empty, and then pumped full of gas from tanker modules. The cluster was an exercise in enhanced Apollo-Saturn technology, of course, and the essence of its design went all the way back to the 1960s. But NASA had had to develop a raft of new techniques to achieve it: the assembly in orbit of heavy components, the long-term storage of supercold fuels, in-orbit fueling.

The catastrophe that lies in wait for us is not connected to a depletion of resources. Energy itself, in all its forms, will become more and more abundant (at any rate, within the broadest time frame that could conceivably concern us as humans). Nuclear energy is inexhaustible, as are solar energy, the force of the tides, of the great fluxes of nature, and indeed of natural catastrophes, earthquakes and volcanoes (and technological imagination may be relied on to find ways and means to harness them). What is alarming, by contrast, is the dynamics of disequilibrium, the uncontrollability of the energy system itself, which is capable of getting out of hand in deadly fashion in very short order. We have already had a few spectacular demonstrations of the consequences of the liberation of nuclear energy (Hiroshima, Chernobyl), but it must be remembered that any chain reaction at all, viral or radioactive, has catastrophic potential. Our degree of protection from pandemics is epitomized by the utterly useless glacis that often surrounds nuclear power stations. It is not impossible that the whole system of world-transformation through energy has already entered a virulent and epidemic stage corresponding to the most essential character of energy itself: a fall, a differential, an imbalance - a catastrophe in miniature which to begin with has positive effects but which, once overtaken by its own impetus, assumes the dimensions of a global catastrophe.

The insatiable need for more processing power -- ideally, located as close as possible to the user but, at the very least, in nearby indus­trial server farms -- invariably leads to a third option: decentralized computing. With so many powerful and often inactive devices in the homes and hands of consumers, near other homes and hands, it feels inevitable that we'd develop systems to share in their mostly idle pro­cessing power. "Culturally, at least, the idea of collectively shared but privately owned infrastructure is already well understood. Anyone who installs solar panels at their home can sell excess power to their local grid (and, indirectly, to their neighbor). Elon Musk touts a future in which your Tesla earns you rent as a self-driving car when you're not using it yourself -- better than just being parked in your garage for 99% of its life. "As early as the 1990s programs emerged for distributed computing using everyday consumer hardware. One of the most famous exam­ples is the University of California, Berkeley's SETl@HOME, wherein consumers would volunteer use of their home computers to power the search for alien life. Sweeney has highlighted that one of the items on his 'to-do list' for the first-person shooter Unreal Tournament 1, which shipped in 1998, was 'to enable game servers to talk to each other so we can just have an unbounded number of players in a single game session.' Nearly 20 years later, however, Sweeney admitted that goal 'seems to still be on our wish list.' "Although the technology to split GPUs and share non-data cen­ter CPUs is nascent, some believe that blockchains provide both the technological mechanism for decentralized computing as well as its economic model. The idea is that owners of underutilized CPUs and GPUs would be 'paid' in some cryptocurrency for the use of their processing capabilities. There might even be a live auction for access to these resources, either those with 'jobs' bidding for access or those with capacity bidding on jobs. "Could such a marketplace provide some of the massive amounts of processing capacity that will be required by the Metaverse? Imagine, as you navigate immersive spaces, your account continuously bidding out the necessary computing tasks to mobile devices held but unused by people near you, perhaps people walking down the street next to you, to render or animate the experiences you encounter. Later, when you’re not using your own devices, you would be earning tokens as they return the favor. Proponents of this crypto-exchange concept see it as an inevitable feature of all future microchips. Every computer, no matter how small, would be designed to be auctioning off any spare cycles at all times. Billions of dynamically arrayed processors will power the deep compute cycles of event the largest industrial customers and provide the ultimate and infinite computing mesh that enables the Metaverse.

Even accepting that EVs and solar panels are or will one day be more energy-efficient than coal- and gas-burning technologies, the bigger question is how fast we attempt to transition. For renewables to provide a majority of our power, we would have to increase wind and solar twenty-fold. But there are not enough rare earth metals on the planet to build such an energy system and then replace it every couple of decades. Replacing a majority of our coal and gas industries with electric ones would exhaust all of our power and resources at one time, massively increasing emissions and environmental degradation in the short run. It could also increase energy inequality, by diverting power and resources to the rebuilding of the energy sector itself. Transitioning slowly, on the other hand, as things wear out, might not create such stresses, but would take many decades to bring us to zero net emissions. Both approaches result in catastrophe. The

China had driven U.S. solar panel manufacturing out of business. Couldn’t it do the same in semiconductors? “This

believed that technological progress was a disease in human society. The explosive development of technology was analogous to the growth of cancer cells, and the results would be identical: the exhaustion of all sources of nourishment, the destruction of organs, and the final death of the host body. He advocated abolishing crude technologies such as fossil fuels and nuclear energy and keeping gentler technologies such as solar power and small-scale hydroelectric power. He believed in the gradual de-urbanization of modern metropolises by distributing the population more evenly in self-sufficient small towns and villages. Relying on the gentler technologies, he would build a new agricultural society.

Even in its first year, our “clean energy moonshot” had begun to invigorate the economy, generate jobs, trigger a surge in solar- and wind-power generation, as well as a leap in energy efficiency, and mobilize an arsenal of new technologies to help combat climate change. I delivered speeches across the country, explaining the significance of all this. “It’s working!” I wanted to shout. But environmental activists and clean energy companies aside, no one seemed to care.

The Love of Money It is not money in itself but the “love of money” that is the root of all evil. When the threat of Climate Change became a national crisis, the families of noted politicians began investing their money in “new green technology,” including solar panels, wind turbines, and electric cars, as informed investors invest where future money is to be made. When COVID hit, there were already certain pharmaceuticals that were used to treat the virus, including one I took that helped me within 48 hours. However, these pills have been available for many years to help prevent malaria but were ignored or not permitted to be sold, as the companies creating the vaccines and various doctors put the word out that these pills were not effective, and only the vaccine would work. According to whistleblower-doctors, the underlying reason for rejecting a cheaper pill is because vaccines would create more money.

And say that over the eons, countless millions of civilizations arose, many of them lasting long enough to venture into space. Spacefaring creatures found each other, linked up, and shared knowledge, their technologies accelerating with each new contact. They built great energy-harvesting spheres that enclosed entire suns and drove computers the size of whole solar systems. They harnessed the energy from quasars and gamma ray bursts. They filled galaxies the way we once spread across continents. They learned to weave the fabric of reality itself. And when this consortium mastered all the laws of time and space, they fell into the sadness of completion. Absolute Intelligence surrendered to nostalgia for

Solar energy can be used for large scale production of electricity in power plants by means of flat plate and concentrator photovoltaic (PV) systems, as well as by thermal concentrated solar power (CSP) systems.

The first solar photovoltaic panel built by Bell Labs in 1954 cost $1,000 per watt of power it could produce.128 In 2008, modules used in solar arrays cost $3.49 per watt; by 2018, they cost 40 cents per watt.129 According to a pattern known as Swanson’s Law, the price of solar photovoltaic modules tends to fall by 20 percent for every doubling of cumulative shipped volume. The full price of solar electricity (including land, labor to deploy the solar panels, and other equipment required) falls by about 15 percent with every doubling. The amount of solar-generated power has been doubling every two years or less for the past forty years—as costs have been falling.130 At this rate, solar power is only five doublings—or less than twelve years—away from being able to meet 100 percent of today’s energy needs. Power usage will keep increasing, so this is a moving target. Taking that into account, inexpensive renewable sources can potentially provide more power than the world needs in less than twenty years. This is happening because of the momentum that solar has already gained and the constant refinements to the underlying technologies, which are advancing on exponential curves. What Ray Kurzweil said about Craig Venter’s progress when he had just sequenced 1 percent of the human genome—that Venter was actually halfway to 100 percent because on an exponential curve, the time required to get from 0.01 percent to 1 percent is equal to the time required to get from 1 percent to 100 percent—applies to solar capture too.

failed to create an arm of the government that will be forever attached to his name, nothing like Obamacare or remotely resembling social security. But the thrust of the Inflation Reduction Act can still be described as transformational—and it will change American life. The theory of the legislation is that the world is poised for a momentous shift. For a generation, the economy has taken tentative steps away from its reliance on fossil fuels. New technologies emerged that lowered the costs of solar panels and wind turbines and batteries; the mass market showed genuine interest in electric vehicles and heat pumps. But the pace of adaptation was slow, painfully slow given the looming changes to the climate. On its own, the economy was never going to evolve in time to avert the worst consequences

of climate change. What was needed was a massive nudge in the right direction. In the past, the stick of regulation and the rod of taxation were the methods that environmentalists believed could break the fossil fuel economy. But the Inflation Reduction Act doesn’t rely on such punitive tactics, because Manchin culled them from the bill. Instead, it imagined that the United States could become the global leader of a booming climate economy, if the government provided tax credits and subsidies, a lucrative set of incentives. There was a cost associated with the bill. By the Congressional Budget Office’s score, it offered $386 billion in tax credits to encourage the production of wind turbines, solar panels, geothermal plants, and battery storage. Tax credits would reduce the cost of electric vehicles so that they would become the car of choice for Middle America. But $386 billion was an estimate, not a price tag, since the legislation didn’t cap the amount of money available in tax credits. If utilities wanted to build more wind turbines or if demand for electric vehicles surged, the government would keep spending. When Credit Suisse studied the program, it estimated that so many businesses and consumers will avail themselves of the tax credits that the government could spend nearly $800 billion. If Credit Suisse is correct, then the tax credits will unleash $1.7 trillion in private sector spending on green technologies. Within six years, solar and wind energy produced by the US will be the cheapest in the world. Alternative energies will cross a threshold: it will become financially irresponsible not to use them. Even though Joe Biden played a negligible role in the final negotiations, the Inflation Reduction Act exudes his preferences. He romanticizes the idea of factories building stuff. It is a vision of the Goliath of American manufacturing, seemingly moribund, sprung back to life. At the same time that the legislation helps to stall climate change, it allows the United States to dominate the industries of the future. This was a bill that, in the end, climate activists and a broad swath of industry could love. Indeed, strikingly few business lobbies, other than finance and pharma, tried to stymie the bill in its final stages. It was a far cry from the death struggles over energy legislation in the Clinton and Obama administrations, when industry scuppered transformational legislation. The Inflation Reduction Act will allow the United States to prevent its own decline. And not just economic decline. Without such a meaningful program, the United States would have had no standing to prod other countries to respond more aggressively to climate change. It would have been a marginal player in shaping the response to the planet’s greatest challenge. The bill was an investment in moral authority.

will be evident from this that Indian entrepreneurs were quick to grasp the possibilities of British and American steam technology. There is no reason to suppose that they would not have been at least as good at imitating it as were their counterparts in, say, Germany or Russia, had the circumstances been different. It was the very fact that India’s ruling power was also the global pioneer of the carbon economy that ensured that it could not take hold in India, at that point in time. The appetites of the British economy needed to be fed by large quantities of raw materials, produced by solar-based methods of agriculture.

The history and features of the solar system's asteroid-comet belts, along with the gravitational influences of the Moon's mass and early orbital proximity, ensured that Earth would receive sufficient impact events, especially before animals appeared, to salt Earth's crust with rich ore deposits. These ores played a crucial role in the early launch of metallurgy and, more recently, in the development of global, high-technology civilization. On the other hand, major impact events during the human era have been so infrequent as to pose no risk to humanity's survival nor to global civilization.

Bookchin looked forward to a future “ecological society, structured around a confederal Commune of communes, each of which is shaped to conform with the ecosystem and bioregion in which it is located.” Everyone will engage in organic farming and use solar and wind power. New technologies will be employed in “an artistic way,” freeing up time for other activities: “gardening, the crafting of objects, reading, recitations,” and experimental mixed farming for biological diversity. The notion of ownership, even collective ownership, will disappear, replaced by “a holistic approach to an ecologically oriented economy.” Instead, “everyone would function as a citizen, not as a self-interested ego,” committing himself to a sense of oneness with the community—and with nature.47

The triumph of the commons is certainly evident in the digital commons, which are fast turning into one of the most dynamic arenas of the global economy. It is a transformation made possible, argues the economic analyst Jeremy Rifkin, by the ongoing convergence of networks for digital communications, renewable energy and 3D printing, creating what he has called ‘the collaborative commons’. What makes the convergence of these technologies so powerfully disruptive is their potential for distributed ownership, networked collaboration and minimal running costs. Once the solar panels, computer networks and 3D printers are in place, the cost of producing one extra joule of energy, one extra download, one extra 3D printed component, is close to nothing, leading Rifkin to dub it ‘the zero-marginal-cost revolution’.

growth of both solar power and electric cars, there’s now a bigger need for better energy storage systems, resulting in a next generation of lithium-ion batteries with increased range, and, as an added bonus, enough power to lift flying cars.

A megatrend is a large social, economic, political, environmental, or technological change highly likely to have major impact across a wide range of areas. Megatrends will affect your company, your customers, your competition—as well as your family, your neighbors, and your community. Examples of megatrends include the rise of alternative energy sources, which are expected to meet 8 percent of the world’s dramatically increasing energy needs by 2030 versus 6 percent of a smaller base in 2010, driven largely by wind and solar,5 the rise of rapidly developing markets like Brazil and China, and increasing connectivity through the Internet and mobile technology. Megatrends are not fads. In spite of what she may think, Lady Gaga does not qualify as a megatrend; however, the rising tendency of consumers to purchase music and many other forms of entertainment from the Internet does. Broad economic shifts, whether long recessions, labor shortages, or the rise or fall of different industries or sectors of the economy,

There are, without a doubt, an incredible number of new and improved technologies arriving every day. Self-driving cars, gene editing, low-cost solar panels, more efficient batteries, biofuel, quantum computers, 3-D printing of metals, artificial intelligence, and on and on and on, Any, or all, of these could generate profound changes in how we live and how we produce the goods and services that go into GDP. That said, it isn't obvious that we'll see profound effects on the growth rate of the economy. Many of those innovations make the production of goods more efficient, but that would only accelerate the shift into services. And there may be a larger question about whether we want to adopt or pursue these innovations at all. As Charles Jones suggested in a recent paper, given our current life expectancy and living standards, the risks inherent in any technology - to the environment, society, or our own health - may not be worth pursuing just to add a fraction of a percentage point to the growth rate.

It is clear that Bhu Mandala, as described in the Bhagvatam, can be interpreted as a geocentric map of the solar system out ot Saturn. But an obvious and important question is: Did some real knowledge of planetary distances enter into the construction of the Bhu Mandala system, or are the correlations between Bhu Mandala features and planetary orbits simply coincidental? Being a mathematician interested in probability theory, Thompson is better equipped than most to answer this question and does so through computer modelling of a proposed 'null hypothesis' -- i.e., 'that the author of the Bhagvatam had no access to correct planetary distances and therefore all apparent correlations between Bhu Mandala features and planetary distances are simply coincidental.' However, the Bhu Mandala/solar system correlations proved resilient enough to survive the null hypothesis. 'Analysis shows that the observed correlations are in fact highly improbable.' Thompson concludes: 'If the dimensions given in the Bhagvatam do, in fact, represent realistic planetary distances based on human observation, then we must postulate that Bhagvata astronomy preserves material from an earlier and presently unknown period of scientific development ... [and that] some people in the past must have had accurate values for the dimensions of the planetary orbits. In modern history, this information has only become available since the development of high-quality telescopes in the last 200 years. Accurate values of planetary distances were not known by Hellenistic astronomers such as Claudius Ptolemy, nor are they found in the medieval Jyotisa Sutras of India. If this information was known it must have been acquired by some unknown civilization that flourished in the distant past.

Most readers might now expect a closing paragraph in which I extoll the nonscientific benefits of manned space exploration: the thrill of the exploration of the unknown; the idea that mankind needs new frontiers if it is not to stagnate; the worry that if mankind is stuck on one planet, a disaster could destroy us. These are appealing ideas. But manned space exploration clearly will not happen unless we find better ways of getting off-planet and creating homelike places elsewhere. I’d like to construct an analogy: we are in the same situation with regard to manned spaceflight today as Charles Babbage was with respect to computing in the 1860s. He invented the basic ideas for the modern computer and tried to implement them using the mechanical technology of his day. The technology was marginally not good enough to allow his analytical engine to be built. We seem to be in the same situation today: chemical rockets with exhaust speeds of a few thousand meters per second are marginally good enough to launch unmanned probes traveling slowly through the Solar System but are completely inadequate for manned missions.

Once superintelligent AI has settled another solar system or galaxy, bringing humans there is easy — if humans have succeeded in programming the AI with this goal. All the necessary information about humans can be transmitted at the speed of light, after which the AI can assemble quarks and electrons into the desired humans. This could be done either in a low-tech way by simply transmitting the 2 gigabytes of information needed to specify a person’s DNA and then incubating a baby to be raised by the AI, or the AI could assemble quarks and electrons into full-grown people who would have all the memories scanned from their originals back on Earth. This means that if there’s an intelligence explosion, the key question isn’t if intergalactic settlement is possible, but simply how fast it can proceed. Since all the ideas we've explored above come from humans, they should be viewed as merely lower limits on how fast life can expand; ambitious superintelligent life can probably do a lot better, and it will have a strong incentive to push the limits, since in the race against time and dark energy, every 1% increase in average settlement speed translates into 3% more galaxies colonized. For example, if it takes 20 years to travel 10 light-years to the next star system with a laser-sail system, and then another 10 years to settle it and build new lasers and seed probes there, the settled region will be a sphere growing in all directions at a third of the speed of light on average. In a beautiful and thorough analysis of cosmically expanding civilizations in 2014, the American physicist Jay Olson considered a high-tech alternative to the island-hopping approach, involving two separate types of probes: seed probes and expanders. The seed probes would slow down, land and seed their destination with life. The expanders, on the other hand, would never stop: they'd scoop up matter in flight, perhaps using some improved variant of the ramjet technology, and use this matter both as fuel and as raw material out of which they'd build expanders and copies of themselves. This self-reproducing fleet of expanders would keep gently accelerating to always maintain a constant speed (say half the speed of light) relative to nearby galaxies, and reproduce often enough that the fleet formed an expanding spherical shell with a constant number of expanders per shell area. Last but not least, there’s the sneaky Hail Mary approach to expanding even faster than any of the above methods will permit: using Hans Moravec’s “cosmic spam” scam from chapter 4. By broadcasting a message that tricks naive freshly evolved civilizations into building a superintelligent machine that hijacks them, a civilization can expand essentially at the speed of light, the speed at which their seductive siren song spreads through the cosmos. Since this may be the only way for advanced civilizations to reach most of the galaxies within their future light cone and they have little incentive not to try it, we should be highly suspicious of any transmissions from extraterrestrials! In Carl Sagan’s book Contact, we earthlings used blueprints from aliens to build a machine we didn’t understand — I don’t recommend doing this ... In summary, most scientists and sci-fi authors considering cosmic settlement have in my opinion been overly pessimistic in ignoring the possibility of superintelligence: by limiting attention to human travelers, they've overestimated the difficulty of intergalactic travel, and by limiting attention to technology invented by humans, they've overestimated the time needed to approach the physical limits of what's possible.

Andrews tapped his fingers on his knees, staring out the helo window. He wondered at the technology that had led the first humans to strap themselves into tiny capsules and launch into space. That had been one hundred and fifty years earlier. In recent decades, humanity had finally left its native solar system and reached

manifold

We should be innovating tomorrow’s technologies rather than erecting today’s inefficient turbines and solar panels. We should explore fusion, fission, water splitting, ...algae grown on the ocean surface that produces oil… This is one more cost of the relentless alarmism. Since we’re so intent on doing something right now, even if it is almost trivial, we neglect to focus on the technological breakthroughs that in the long run could actually allow humanity to move away from fossil fuels.” -pp. 14, 15

the ability to move from idea and invention to technologies and innovation and finally into the marketplace. This is not something that necessarily happens fast—energy is not software. After all, the lithium battery was invented in the middle 1970s but took more than three decades before beginning to power cars on the road. The modern solar photovoltaics and wind industries began in the early 1970s but did not begin to attain scale until after 2010. Yet the pace of innovation is accelerating, as is the focus, owing in part to the climate agenda and government support, in part to decisions by investors, in the part to the collaboration of different kinds of companies and innovators, and in part to the convergence of technologies and capabilities—from digital to new materials to artificial intelligence and machine learning to business models and more.

Although many people, for example, believe the Mars Rover robots are champions of Artificial Intelligence, the robots do not “employ state-of-the-art AI algorithms.” Dey said he learned the distinction while collaborating with the NASA Jet Propulsion Laboratory dedicated to robotic exploration of the solar system. AI algorithms require extensive energy consumption to be computed — something that would quickly put the rover out of action in outer space. “On Mars, while exploring several large craters where sunlight might never reach, the rover has to commute and communicate in an optimized fashion with the least amount of external power source,” he said. “And having the state-of-the-art AI algorithm on such a robot would only drain the power source quicker.” But that doesn’t mean the rover isn’t smart in its own way. “Every ounce of the robot is optimized to perform the best at minimal cost,” he said. “So, next time, if you hear about Mars rover then be aware that it is the hard work and dedication of several intelligent researchers and engineers who had made that machine intelligent enough to do its job.

Along all the process steps of making electricity out of fossil fuels, at least 50% of the initial available chemical energy is lost in the various conversion steps.

However, the power density at the centre of the Sun is estimated by theoretical assumptions only to be about 275 W/m3. As we have seen in Chapter 1, the average power of an adult male is 115.7 W. If we assume his average volume to be 70 L, i.e. 0.07 m3, the average power density of the human body is 1650 W, hence much higher than the fusion power in the centre of the Sun!

But my colleagues in academia had shown me that solar technologies far superior to today’s already exist in the lab. If they could be refined and mass-produced, they could one day make it possible to harness the sun’s energy much more efficiently and cheaply.

We don’t have GPS on Mars,” says Tomas Martin-Mur, an engineer at NASA’s Jet Propulsion Laboratory who has done navigation work for several Mars missions, including the Mars Science Laboratory, the ambitious mission that brought the rover Curiosity to the red planet in 2012. Nor is there any GPS for the solar system, he adds, which would be a useful way to correct for the effects of solar radiation—just one of the many things that can send a spacecraft off-course. The only GPS we have is on Earth, so we’ve harnessed it for space travel.
