All of us have known power — big power, available cheaply — our whole lives. You always have a 100-horsepower or 200-horsepower car and all the heat you need in your house, and so on. It’s hard to realize that just 200 years ago, all our ancestors were getting by for transportation on biological power — walk, run, whatever, use a horse. Then occasionally, you’d use windmills for some things, and water power, and there’d be sailboats. Basically, we got by on those puny powers, and now we can’t even conceive of how we would do it. So here is this Britisher who, in effect, said, “Go back to the power that we were using — but use modern technology — and fly. Fly on a third of a horsepower.” That was an amazing challenge of great value — to think of biology and nature at the same time that we are thinking of technology, and also to think about how little energy and materials we could get by with. This challenge was not just another ordinary one; it had great value. We can see that challenge produced our — and the significant prize — produced our Gossamer Condor, without which there would not have been the Gossamer Albatross, without which there would not have been the Solar Challenger or the Pterodactyl. Without all of these, there wouldn’t have been the Sunraycer, the solar-powered car that won the race across Australia in ‘87. And without that, there would not have been the Impact battery-powered car that now is going into mass production. As you look back in roots, you realize that was a pretty important lunch that took place many, many decades ago.
