Klaus Ohlmann and Jonas Lay in the one-and-only eGenius just completed a 2,003 kilometer (1,244 mile) trip from Germany to the Atlantic Ocean on the southern tip of France and return.  The numbers are spectacular.  The flight averaged 190.36 kilometers per hour (118.28 mph) and its hybrid power system consumed a mere 81 liters of fuel.  That works out to 24.72 kilometers per liter or 58.15 mpg.  Even a Prius at that speed would guzzle gasoline. Hybridizing eGenius eGenius was to have originally been HydroGenius, flying on gaseous hydrogen.  Starting design in 2006 and as presented at the 2009 Electric Aircraft Symposium, HydroGenius was designed by Rudolf Voit-Nitschman, Len Schumann, and Steffen Geinitz of the IFB, Institute of Aircraft Design …

Flying e-Genius for Two Years

At this year’s Electric Aircraft Symposium, Rudolf Voit Nitschmann, Len Schumann, and Ingmar Geiss shared their well-documented experiences with e-Genius, second place winner in 2011’s Green Flight Challenge.  Flown by Erik Raymond and Klauss Ohlmann, the airplane managed 397.5 passenger miles per gallon on its 200-mile trek around a closed circuit between Santa Rosa, California and the distant geothermal power plants that provided the electricity for its flight. As Voit Nitschmann, leader of the e-Genius team since 2005 noted, one must design electric aircraft around the beneficial aspects of such vehicles to gain the greatest performance.  Originally slated to be hydrogen powered, e-Genius mounts its 59-pound motor on the leading edge of the vertical rudder, more difficult with a heavier …
