Via Energy Daily:- Chicago IL (SPX) "Researchers at Saint Louis University in Missouri have developed a fuel cell battery that runs on virtually any sugar source - from soft drinks to tree sap - and has the potential to operate three to four times longer on a single charge than conventional lithium ion batteries, they say..."This study shows that renewable fuels can be directly employed in batteries at room temperature to lead to more energy-efficient battery technology than metal-based approaches," says study leader Shelley Minteer, Ph.D., an electrochemist at Saint Louis University (pictured). "It demonstrates that by bridging biology and chemistry, we can build a better battery that's also cleaner for the environment." As proof of concept, she has used a small prototype of the battery (about the size of a postage stamp) to successfully run a hand-held calculator." Reportedly, materials used to build the sugar battery are biodegradable. Funding for the study was provided by the U.S. Department of Defense. Dr. Minteer's previous work involved an alcohol powered fuel cell. So...what happens if you feed the sugar battery a classic bum wine?
