The winning plane was able to fly travel 200 miles in less than two hours and use less than four liters of fuel per passenger.
NASA hopes the new technology developed for the challenge will inspire more innovations in electric-powered aircraft.
"When you think about it, an electric motor has fewer moving parts than a conventional gasoline powered engine, so in addition to much-reduced emissions and higher efficiency, we think they have the potential to be much more reliable by being much more simpler, we think it's a win-win all the way around," NASA Ames spokesperson Joe Parrish said.
NASA teamed with Google in the competition, which was held all last week in Santa Rosa.
