Engineers want to fill up your tank with sunlight Science (Aug 7, 2014)

Many cities and countries look to solar energy to replace coal burning power plant. Now a group of chemical and mechanical engineers want to harness the power of the sun to fuel cars, airplanes and semi-trucks.

If the energy from sunlight can be harnessed and boosted in a single spot, it can be used to break chemical bonds, explains California Institute of Technology chemical engineer Sossina Haile.

“What we’re doing is collecting enough to get a lot of heat and using that to drive chemical reactions,” Haile said, breaking water into hydrogen fuel or carbon dioxide into carbon monoxide.

She and University of Minnesota mechanical engineer Jane Davidson are working on that. In Davidson’s lab a solar simulator, an array of seven 7,000-watt lightbulbs, focuses its beams on a brick. It cranks out heat — 2,700 degrees Fahrenheit, enough to burn a hole through the brick. These experiments will help them understand how to harness that much energy and turn it into solar fuel.
