“The thumb-size black strip looks like a thin magnet. But in reality, it is an artificial leaf, made of silicon and capable of using sunlight to split water into hydrogen and oxygen that can be fed into fuel cells to make power. “You drop it in a glass of water and you walk outside and hold it in the sun, and you’ll start to see bubbles of hydrogen and oxygen,’’ explained Daniel Nocera, an MIT professor who led the team that invented the device.”
Quite cool.
