Move over trees. Here comes the sun

Scientists are exploring new ways to tap the sun’s energy directly, without the help of plants, to create potential fuel sources. “The main problem with current solar power technology is that if the sun’s not shining, you’re out of luck,” says Tom Meyer. “Solar fuels give us the ability to collect and stockpile that energy.”
