CARROT JUICE
Compost isn't just for your garden anymore:  Scientists at the
University of the West of England have created a microbial fuel-cell
battery powered by organic waste.  The miniature battery converts
biochemical energy from food into electricity, using E. coli bacteria
that release hydrogen atoms as they break down carbohydrates.  The
fuel cell runs on sugar cubes, and the scientists are currently using
it to run a light-sensitive robot.  But eventually a series of
connected cells, sold for about $15 each, could power home
appliances, the scientists say.  And possible creative improvements
abound:  "They aim to move on to carrot power," New Scientist
magazine reported.
