Astounding Final Results from the Green Flight Challenge Sponsored by Google
The 2011 Green Flight Challenge sponsored by Google marks an historic achievement in aviation—the first demonstration of practical, cross-country emission-free flight. Team Pipistrel-USA.com’s winning 4 seat, electric-powered aircraft, the Taurus G4, flew nearly 200 miles non-stop while achieving 403.5 passenger MPG! Its astounding efficiency was more than twice that of the piston-powered aircraft in the competition. Equally promising: Team e-Genius won the Lindbergh Prize for Quietest Aircraft, with a peak take off noise of just 59.5 dBA at a 250 foot sideline. This achievement heralds the real transformative potential unique to electric powered aircraft—the capability to be quiet enough to land very near dwellings and businesses.
Years from now, these first Green Flight Challenge team members will be recognized as the pioneers of the Age of Electric Flight. CAFE is already discussing plans for GFC II and will publish more on that here soon.
Thanks to Everyone Who Made the Green Flight Challenge Happen!
The CAFE Foundation wishes to thank all of their sponsors, partners and volunteers for making this historic competition happen. Together we have achieved something great and the future for Green Flight looks bright!

CAFE has just arranged for Len Scumann and Steffen Geinitz from the University of Stuttgart, Germany to come to EAS III to present their exciting work on the new Hydrogenius fuel cell 2 seat aircraft.
By invitation, CAFE officials made a special visit to Stanford's Artificial Intelligence Laboratory to explore its advanced work in pilotless vehicles. Stanford's Adam Coates and Michael Montemerlo hosted the visit, which included a look at the sensors, hardware and software that enable Stanford's autonomous helicopter and DARPA Challenge Car to pilot themselves.
A short drive around campus in the car revealed its amazing real-time capabilities to detect and avoid obstacles. CAFE believes that such capabilities, when applied to personal aircraft, will greatly enhance their safety and consumer popularity.
