Remember electrolysis from the chemistry class? Yes, the process of separating oxygen and hydrogen by decomposing water. Dan Nocera, an M.I.T chemist claims that he has found a way of using sun-light to perform a photosynthesis like process to generate energy. Nocera’s method will use carbon-dioxide, water and sunlight to convert it into oxygen and energy. The amount of energy generated from one bottle of drinking water is expected to power a whole house.
Watch this video uploaded by US department of energy and hear Dan Nocera himself expliaining this process:
If things actually start working this way, the day is not far when every house will generate its own power and the concept of power grids will be found in the books of history only.
