Unusual three-wheeler can fly for only 10 minutes at a time.
In the end, the competition for the $1.35 million top prize in the 2011 Green Flight Challenge came down to just two craft, the eGenius and the Pipistrel G4. After both managed to meet the goal of the contest – fly 200 miles at over 100 miles per hour using less than the equivalent energy of one gallon of fuel per passenger – the winner seems to have been determined by its efficiency score.
Cessna has built over 43,000 of its 172 Skyhawks since introducing the airplane back in 1955 and, until now, all have burned aviation fuel (Avgas) to fly the friendly skies. That is set to change as the ol' air-dog will learn a new trick this year with its manufacturer announcing that it is teaming up with Bye Energy to produce an electric-powered proof of concept (POC) version of the venerable bird.
If you have a strong interest in electric vehicles taking flight (in both the metaphoric and non-metaphoric senses) than you may want to attend the upcoming Electric Aircraft Symposium on April 24th at the Hiller Aviation Museum in San Carlos, California. The impressive line up of speakers features such notables as Dr. Yi Cui of nanowire battery breakthrough fame and will touch on subjects ranging from climate science to the proposed Aviation Green Prize (an Automotive X-Prize type competition).
