A Pennsylvania company has won a $1.35 million prize from NASA for developing a highly efficient airplane power by electricity.
Pipistrel-USA.com of State College earned the top prize in the CAFE Green Flight Challenge, sponsored by Google, NASA announced Monday.
The plane developed by Pipistrel doubled the fuel efficiency requirement for the competition - flying 200 miles in less than two hours while using less than a gallon of fuel per occupant or the equivalent in electricity. The winning plane used a little more than a half-gallon of fuel per passenger for the 200-mile flight.
Team Pipistrel-USA.com was one of 14 entrants in the competition, which began two years ago. In total, the 14 teams invested $4 million in the competition, according to NASA.
"Two years ago the thought of flying 200 miles at 100 mph in an electric aircraft was pure science fiction," Jack W. Langelaan, team leader of Team Pipistrel-USA.com, said in statement. "Now, we are all looking forward to the future of electric aviation."
Second place, and a $120,000 prize, went to Team eGenius of Ramona, California, whose leader, Eric Raymond, congratulated Team Pipistrel.
The winning aircraft, the Pipistrel Taurus G4, is a four-seat, twin-fuselage aircraft powered by a 145-kilowatt brushless electric motor driving a two-blade propeller mounted on a spar between the fuselages. The plane's wingspan is about 75 feet.
"I'm proud that Pipistrel won. They've been a leader in getting these things into production, and the team really deserves it, and worked hard to win this prize," Raymond said in a NASA statement.
"Electric aircraft have moved beyond science fiction and are now in the realm of practice,"Â Joe Parrish, acting chief technologist at NASA headquarters in Washington, said in a statement.
The planes flew last week out of Charles M. Schulz-Sonoma County Airport in California. Only three of the 14 entrants made it into the air, according to The Santa Rosa Press-Democrat. The airport is home to the Comparative Aircraft Flight Efficiency Foundation, which organized the competition with NASA.
