    Electric Aircraft Competition Wraps, With $1.35M Prize For Plane That Out-Economizes A Prius

    A little more than a year ago, we posted about the possibilities of electric aircraft. At the time, we also mentioned an upcoming competition that would test the mettle of these flying batteries: the CAFE Green Flight Challenge. It’s a NASA event (and purse), sponsored by Google, which like the X-Prize aims to fund innovation through competition. Entrants would have to fly 200 miles in… Read More

  • Why Did Solyndra Fail So Spectacularly?
