Roger Angel, an astronomer at the University of Arizona, stands in front of his new project: a solar tracker. Angel wants to use the device to harness Arizona's abundant sunlight and turn it into usable energy.
You may not be familiar with the name Roger Angel, but if there were ever a scientist with a creative streak a mile wide, it would be he.
Angel is an astronomer. He's famous for developing an entirely new way of making really large, incredibly precise telescope mirrors. But his creativity doesn't stop there. He's now turned his attention to solar power, hoping to use the tricks he learned from capturing distant light from stars to do a more cost-efficient job of capturing light from the Sun.

Better Place is building a network of electric car battery changing stations throughout Israel. The idea is to make changing a spent electric battery as easy as pulling into the gas station for gasoline. Here, Better Place CEO Shai Agassi is shown in front of a cutaway model of an electric car at the company's showroom in Tel Aviv earlier this month.
It looks like a bright new car wash, but it's a battery swapping station for electric cars in Israel. When a vehicle pulls up, it is slowly pulled through a conveyor. The spent battery is taken out and replaced with one that is fully charged. The entire process takes less than five minutes.
