University of Nevada, Reno professor Manoranjan Misra is working on a new process for generating pure hydrogen utilizing two of the most abundant resources available, sunlight and water. Utilizing a new material made up of billions of nano-tubes, water is passed through and ultrasonic waves energized by sunlight cause the water to be broken down into hydrogen and oxygen. He estimates that this process could yield hydrogen at the gasoline energy equivalent cost of about $1 gallon.[Source: PhysOrg VIA-www.autobloggreen.com]
