MIT’s artificial leaf is ten times more efficient than the real thing (Wired UK).
MIT professor Daniel Nocera claims to have created an advanced solar cell which uses sunlight to split water into its two core components, oxygen and hydrogen.
With a single gallon of water, Nocera says, the chip could produce enough electricity to power a house in a developing country for an entire day. Provide every house on the planet with an artificial leaf and we could satisfy our 14 terrawatt need with just one gallon of water a day.
