man made photosynthesis

professor Daniel G. Nocera of MIT and Matthew Kanan have found a way for humans to do something plants do naturally. to create energy from the sun's rays and water.

what the scientist have found is a way to split water apart so you have oxgen and hydrogen.

They dissolved cobalt and phosphate in water and then zapped it with electricity through an electrode. The cobalt and phosphate form a thin-film catalyst around the electrode that then use electrons from the electrode to split the oxygen from water. The oxygen bubbles to the surface, leaving a proton behind.

A few inches away, another catalyst, platinum, helps that bare proton become hydrogen.

this process could be a cheaper way to power fuel cell batteries.
