Batteries Powered by Leftover Food

Posted by michael on from the my-refrigerator-suddenly-becomes-very-valuable dept.

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." There's also a New Scientist article. The New Scientist would like to point out that they broke the story, and the BBC followed up.

    a battery that uses E.Coli to break down food.

    Smart people, smart. I assume that either the case is indesctructable or that the strain of bacteria is modded to be harmless?

    1 W = 1 J/s. 1 kcal = 1 Cal = 4000 J. Therefore, if I want 3 kW of power continuously (which is about how much an average US home uses), I would need to feed my HomeStomach(TM) Generator less than 3/4 Calorie/second. My suggestion is to stock up on Tic-Tacs.

    Nice math, yourself.

    I think sugar has about 5 Cal/g so that's 250 Cal = 1,000,000 J. Keeping in mind that "4000 J/C" is an approximation, their numbers are right.
