Sony develops prototype battery, runs on sugar

Sony Corp., Tokyo, Japan, has developed a prototype battery that runs on sugar, breaking down a glucose solution to generate electricity, reports MarketWatch. The method has so far generated 50 milliwatts, enough power to run a Walkman music player, says the company. Since sugar is a renewable resource, use of it as a power source should be environmentally friendly, reports said. The battery's casing is made from a vegetable-based plastic and Sony said it would produce the batteries for commercial use but didn't say when, says MarketWatch.
