Thomas Senkel and Electric Vertical Mobility

Thomas Senkel was an early part of Volocopter, initially called e-Volo.  His first efforts resulted in a spider-like creation perched on an exercise ball.  It flew, seemed stable, and despite the placement of whirling propeller blades encircling Thomas during his test flights, proved not a hazardous as it looked. Explanatory material accompanying the video declared, “The first manned flight with an electric vertical take-off and landing multicopter (eVTOL) was performed by Volocopter. The flight lasted 90 seconds, after which the pilot Thomas Senkel stated ‘The flight characteristics are good natured. Without any steering input it would just hover there on the spot.’ The flight, which is a Guinness World Record, was performed on October 21st in 2011.” Although he helped develop the e-Volo which transfigured into Volocopter variants, Thomas apparently left the company to strike on his own patent-filled adventures.

JoeBen Bevirt, founder and CEO of Joby Aviation, Joby Motors, and related enterprises, has thought long and hard about the financial costs and lost productivity brought about by the daily automotive commute, a 1.6 hour per day ordeal for many in our urban centers.  JoeBen and the Atlantic magazine agree that commuters squander 5.5 billion hours and 2.9 billion gallons of fuel annually, stuck in the fitful despair of slow or unmoving traffic, sharing only frustration and polluted air with their fellow motorists. JoeBen told attendees at the April Electric Aircraft Symposium that several years before, he had the seeming pipe dream of moving people by air in a single-seat, eight-motorm, vertical takeoff and landing, electric commuter aircraft that would take one 100 miles at 100 miles per hour for one dollar.  The combination of Greg Cole’s Sparrowhawk and electric power focused too much on efficiency, according to JoeBen, and battery technology had not evolved to allow the practical outcome …
