Sugar in your tea…or battery?

prototype-bio-battery-systePointer to the future: The US Department of Defense’s always interesting ‘Armed with Science’ profiles a bio-battery under development, only a little larger than a 9V, powered by about 20ml of….sugar solution. Enzymes convert the sugar into power and to recharge, just add more solution.  It’s stable, non-explosive and uses highly portable elements. For the armed forces, the potential is substantial–soldiers carry up to 40 lbs. of batteries on missions.  For the medical market–think sensors, scanners, field hospitals for disaster response, even implants that use the body’s own sugars. The Bio-Battery:  Converting sugar into electrical energy.
