With Solar Impulse descending on Washington, D. C., the Cross USA flight reached a symbolic conclusion, bringing the future to a capitol that seems resistant to even modest change, let alone radical departures from current, conventional reality. http://www.youtube.com/watch?v=n64tAJs_c8w With one hop to go in its journey, Solar Impulse has spread the message of what might be if we have the will to overcome the inertia brought about by our well-lobbied legislature. Andre Borschberg and Bertrand Piccard have one more opportunity to challenge the world to adopt green energy when Solar Impulse goes to New York City. Monday, they met with Energy Secretary Ernest Moniz, with whom they participated in an energy roundtable and news conference about the technology that made …

Erik Raymond is moving his shop and Sunseeker Duo project to Voghera, Italy, nestled in Northern Italy between Milan and Genoa.  He showed the completed airframe at this year’s Aero Expo at Friedrichshafen, Germany and discussed, no doubt, the future of electric aviation with Axel Lange, the CEO of Lange Aviation.  Lange has developed the Antares and Arcus electric motorgliders, both outstanding designs. Following the Expo’s finale, Erik and his wife Irena drove south to Italy, where their enterprise will complete work on the Duo and plan for their proposed trips in unexplored realms– all on solar power. With Solar Impulse crossing the United States (which Erik did in 1990 in Sunseeker I) and more flights planned by other participants, …

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 …

Floating Over the Danube: The Vision of the Little Tailor of Ulm Lives

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

The beautiful blue Danube River of Strauss waltz fame, “…Rises in the Black Forest mountains of western Germany and flows for some 1,770 miles (2,850 kilometers) to its mouth on the Black Sea. Along its course, it passes through nine countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Romania, and Ukraine,” according to the Encyclopedia Britannica. In 1811, Albrecht Ludwig Berblinger, a tailor in the city of Ulm near the headwaters of the second longest river in Europe, tried a novel idea – flying across the river on a nicely sewn-together hang glider.  His splashdown marked the end of his aeronautical career, but made him famous and an unlikely harbinger of things to come. City fathers have announced, “In the spirit of Berblinger, and continuing his vision, the City of Ulm aims to promote …
