Q&A with 'Ingenious' author Jason Fagone on the legacy of X Prize [w/video]
The comments about "we need a better battery" miss the point of the X-Prize, which showed that we need better cars. Seven is about 2X as efficient as most OEM EV's. It has ~2.5X the range of the Leaf using a battery that is less than 50% larger capacity. The eVLC has more range than the Leaf with less than half the battery.
