From Gizmodo:
"After six long years of planning, talking and hard work, the world finally got its first look at the 100% solar-powered Solar Impulse HB-SIA on June 26th. This remarkable feat of engineering, with the wingspan of a Boeing 747 but only the weight of an average family car, has over 12,000 solar cells powering four electric motors with a maximum power of 10HP. The aircraft prototype is expected to take its first flights before the end of the year."
This plane does not seem like that much, but in terms of the electric vehicle revo9lution it will be a bit of a milestone, assuming it completes its mission.
Sure, a car can run off electricity; if it runs out of charge it just stops. This plane has a bit more of a vested interest in not stopping.
I think it's also a test of the validity of lightweight construction materials as a way of reducing overall Carbon emissions.
