Using Solar Energy to Make Fuel

A Professor of Chemistry at MIT, Daniel Nocera, has developed a process to use the sun + water to make hydrogen fuel. This process is similar to photosynthesis. It can also be used to make fresh water out of seawater.

Now it needs to be scaled up for practical use. Let us hope this is done soon, regardless of the falling cost of oil. We will need this down the road, so why wait for a crisis.
