Article] Microbe fuel cell packs more power |
Microbe fuel cell packs more power
New anode harvests ten times more electricity from bacteria.
4 July 2003
PHILIP BALL
German researchers are generating ten times more electricity than before
from bacteria.
Uwe Schröder and colleagues at Ernst Moritz Arndt University in
Greifswald have created a prototype microbial fuel cell that captures
the energy produced by Escherichia coli as it feeds on sugar1. Making up
to 150 milliamps, the bacterial battery can drive a medical ventilator,
for example.
Many microorganisms convert sugars and other carbohydrates to alcohols,
acids and carbon dioxide. When no air is present, this fermentation
process can also produce hydrogen - the fuel in most fuel cells, such as
those being developed for 'green' electric vehicles. The energy released
by the reaction of the gas with oxygen generates electricity.

So it is just smaller, a horse walking round will give more milli amps.
Now you have smaller little beasties working for you.
Wait until the animal lobby hears about it!
