...American Society of Mechanical Engineers and won him worldwide acclaim. Now at 75 he is still spewing out offbeat and innovative ideas faster than his creative team at AeroVironment can act on them. Currently in the works are projects ranging from a solar-powered, unmanned plane with a wingspan nearly as large as a football field to a pocket-size device that substitutes for a visit to the health club to a contraption that literally makes a backpacking hiker light on his feet...
