The next frontier in green transportation is bound to be flight travel, which is why it is not surprising to see that NASA just announced the Green Flight Challenge. The competition will be awarding a prize of $1.5 million to the first plane to achieve 100 miles per hour, for 200 miles. That may not sound that impressive until you realize that the plane must achieve an efficiency of 200 passenger miles per gallon – not an easy feat!
Who will win? No guesses yet, but we will definitely let you know and keep you updated on any entrants.
