I'm all about using the power of the sun to juice up my gadgets, not only to save me some cash, but also to help keep the planet lean and green. Although there are no solar-powered cars hitting the streets yet, there happens to be a plane that just completed its first overnight voyage powered entirely by the sun.The Solar Impulse, packed with 12,000 solar cells, embarked on a 24-hour trip yesterday and landed in Switzerland after flying for a full 26 hours on solar energy. Banking up power from the sun for its overnight leg, the plane reached a top speed of 76 mph and experienced temperatures so cold they killed the pilot's iPod battery! And in case you're wondering — no, it's not a hybrid plane. The Solar Impulse emits no pollution and doesn't use any gasoline. It's an amazing step toward harnessing natural energy for modern-day uses. I can't wait to see more vehicles — planes, trains, and automobiles — going green and using natural energy sources in the future. Want to get involved?
