Someday soon, we could be filling the gas tank with some help from the sun and some bacteria. Harvard researchers have developed a method to turn solar power into liquid fuel.
The first step involves using a solar panel to drive a chemical reaction. The panel powers a special catalyst that reacts in water to separate it into hydrogen and oxygen. (Video via BBC)
Harvard researcher Daniel Nocera created just such a catalyst — which he calls the artificial leaf — a few years ago. (Video via MIT)
