In 1998, aircraft designer Paul MacCready shares his vision of an earth out of balance, and talks about the steps he’s taking in his own work to help solve it — by building amazing solar airplanes, superefficient gliders and an electric car. It’s a stirring vision of how all of us, no matter what our profession, can help make change. Listen for MacCready’s rule to live by: “I spend about 15 percent of my time trying to save the world.” (And watch for the aircraft demos soaring over the heads of a roomful of TEDsters.) (Recorded February 1998 in Monterey, California. Duration: 22:48.)
