Modern biomimicry is far more than just copying nature's shapes. It includes systematic design and problem-solving processes, which are now being refined by scientists and engineers in universities and institutes worldwide.
The first step in any of these processes is to clearly define the challenge we're trying to solve. Then we can determine whether the problem is related to form, function, or ecosystem. Next, we ask what plant, animal, or natural process solves a similar problem most effectively. For example, engineers trying to design a camera lens with the widest viewing angle possible found inspiration in the eyes of bees, which can see an incredible five-sixths of the way, or three hundred degrees, around their heads.
The process can also work in reverse, where the exceptional strategies of a plant, animal, or ecosystem are recognized and reverse engineered. De Mestral's study of the tenacious grip of burrs on his socks is an early example of reverse engineering a natural winner, while researchers' fascination at the way geckos can hang upside down from the ceiling or climb vertical windows has now resulted in innovative adhesives and bandages.
Designs based on biomimicry offer a range of economic benefits. Because nature has carried out trillions of parallel, competitive experiments for millions of years, its successful designs are dramatically more energy efficient than the inventions we've created in the past couple of hundred years. Nature builds only with locally derived materials, so it uses little transport energy. Its designs can be less expensive to manufacture than traditional approaches, because nature doesn't waste materials. For example, the exciting new engineering frontier of nanotechnology mirrors nature's manufacturing principles by building devices one molecule at a time. This means no offcuts or excess. Nature can't afford to poison itself either, so it creates and combines chemicals in a way that is nontoxic to its ecosystems. Green chemistry is a branch of biomimicry that uses this do-no-harm principle, to develop everything from medicines to cleaning products to industrial molecules that are safe by design. Learning from the way nature handles materials also allows one of our companies, PaxFan, to build fans that are smaller and lighter while giving higher performance. Finally, nature has methods to recycle absolutely everything it creates. In natures' closed loop of survival on this planet, everything is a resource and everything is recycled-one of the most fundamental components of sustainability. For all these reasons, as I hear one prominent venture capitalist declare, biomimicry will be the business of the twenty-first century. The global force of this emerging and fascinating field is undeniable and building on all societal levels.
