They flew just a few months before Larry Mauro lofted his solar-riser in April 1979. Both airplanes were limited by the technology of the day, lithium-ion batteries still over a decade away, and the best solar cells achieving less than five-percent efficiency. Fred wrote to tell your editor of the award. “I was in Montreux Switzerland a few weeks ago, and on the 22nd of October I received an award from prince Albert II of Monaco for Solar One, which is now formally accepted as the first solar powered aircraft to fly.

Announced at Friedrichshafen’s Aero Expo and displayed (at least in model form) at the 2013 Paris Air Show, the Elektro E6 is the technology platform for a future, all electric transport aircraft. With low CO2 emissions, noise and vibration, the six-seat, two-motor airplane features full carbon composite structure.  Solar cells on its high wing could help extend the range for this machine to 500 kilometers (310 miles), predicted if battery developments continue at their current pace for the next six years.  The light twin would boast a payload of 480 kilograms (1,065 pounds). The E6 comes about as part of an Agreement of Cooperation between PC-Aero GmbH and EADCO GmbH.  Rosario De Luca’s EADCO (European Aerospace Design Consultants), capable of supporting …
