Artificial Leaf = 10 * Real One

• "The artificial leaf uses nickel and cobalt as catalysts to split water molecules into hydrogen and oxygen by facilitating oxygen-oxygen bonding.
• Oxygen and hydrogen molecules are then sent to a fuel cell that can produce electricity. If the device is placed in a one-gallon bucket of water in bright sunlight, it can reportedly produce enough electricity to power a house in a developing nation.
• This new artificial leaf uses nickel and cobalt, which are relatively cheap, and has so far operated continuously for at least 45 hours, making it the first practical artificial leaf."
