A spoon full of Sugar helps the energy use go down....

BYU scientists made a fuel cell powered by sugars like glucose using a common weed killer serves as the catalyst they feel with design improvements can be a clean energy source for gadgets, cars or homes

BYU chemistry professor Gerald Watt found the catalyst to harvest electricity from sugars

"Carbohydrates are very energy rich," said BYU chemistry professor Gerald Watt. "What we needed was a catalyst that would extract the electrons from glucose and transfer them to an electrode." The effectiveness of this cheap and abundant herbicide is a boon to carbohydrate-based fuel cells. By contrast, hydrogen-based fuel cells like those developed by General Motors require costly platinum as a catalyst. Read more at BYU
