One main goal in the renewable energy field is to find an efficient, inexpensive way to split water into hydrogen and oxygen. The hydrogen could then be used as a fuel source for vehicles or fuel cells. Typically, an electric current breaks the water down. Now, there’s a new water-splitter: a virus. M.I.T.’s Angela Belcher took her cue from plants, where special pigments capture solar energy in photosynthesis, involving the splitting of water. [More]
