as we do oil or natural gas, to power cars, create heat or generate electricity, and we can store the fuel for use when the sun is down. Lewis’s lab is one of several that are crafting prototype leaves, not much larger than computer chips, designed to produce hydrogen fuel from water, rather than the glucose fuel that natural leaves create. Unlike fossil fuels, hydrogen burns clean. Other researchers are working …
