Batteries Powered by Leftover Food

Lazyhound writes "Technologists at the University of the West of England in Bristol have come up with a cheap, organic battery that can run on household leftovers, and be manufactured for just £10."

    Further extrapolation:
    40W bulb * 8 hours = 40 J/s * 8 hr = 1,152,000 J
    50g sugar * 4 Cal/g = 200 Cal = 800,000 J
    Aren't they off by a factor of 2?
