British handymen have just brought into service the first Web
server which draws its energy from potatoes! A dozen tubers connected
in series provide energy necessary to supply a simplified computer,
not very greedy in electricity. It presents to the public a small Web
site of two pages, briefly explaining technology used. It is about
the most recent exploit as regards servers minimalists, extremely
popular in certain data-processing mediums.
To force potatoes to produce electricity, one introduced
there electrodes of zinc and copper. The flesh of vegetable, slightly
salted and acid, acts like an electrolyte (a little like the acid a
battery) and is enough to cause an electrolytic reaction. Each tuber
produces approximately 15 milliamperes of current, with a tension of
0,8 volt. The output decreases after 15 hours and one needs new
potatoes the every day ( Cybersciences )
