Artificial Leaf turns Water into Energy for Cheap

A Massachusetts Institute of Technology (MIT) research team, lead by Dr. Daniel Nocera, have created a functioning artificial leaf which in reality is an advanced playing-card sized silicon+catalyst solar cell that can power a house in a developing country for a day using a gallon (3.79 liters) of water and sunlight....

The oxygen and hydrogen can either be passed through a fuel cell to generate electricity, or burned to generate heat. All the leaf needs is water and sunlight, and it will work for at least 45 hours without degrading in performance according to testing done in the lab.
