+ - Hydrogen Fuel made with Sunlight and Zinc->

Submitted by

gordona writes "Perhaps free energy or nearly free is on the way. A PhD student at the University of Delaware had demonstrated how that free hydrogen gas can be generated with sunlight, zinc oxide, and water. A chamber that holds the zinc oxide is heated by concentrating sunlight to 3500 degrees Fahrenheit which vaporizes the zinc. The zinc vapor can then be put into water which then reacts to form zinc oxide releasing hydrogen. It isn't stated how the zinc vapor is separated from the oxygen that is generated however and its not clear if the process is scalable."
