As a college freshman in 1992 interested in building aircraft capable of taking off and landing vertically, JoeBen Bevirt landed in the right place: the lab of flying car pioneer Paul Moller at the University of California, Davis.
But despite deep respect for Moller, Bevirt soon concluded that it wasn’t going to work. The rotary gas-powered engines Moller was developing for his Skycar were intolerably loud and research Bevirt did on batteries led him to believe it would be decades before they would contain enough energy at a low enough weight to make a quieter electric vertical takeoff and landing (VTOL) aircraft possible. He turned to robotics instead.
