If you want to experiment, you can get a whole heap of graphite rods and zinc cans (both from old dry cell batteries) and put one of each in each spud and series and parallel them together to run a high-brightness LED.

Stuff we did in grade school.
Learned more about what was going on in highschool chemistry. Stuff that guys with names like Volta and Galvani and Ampere figured out in the early 1800's. http://en.wikipedia....i/Lemon_battery
Note that the potato is only part of the setup and provides only part of the energy output. One of the electrodes is consumed also, providing the other part of the energy.
I figured that the "date" of the original poster pulled an April Fool prank. If not, had ignorant college professors...

On the other hand, potatoes are easy to grow and plentiful, so maybe this should go in Shortpoet's Outrageous Green Ideas thread.

Hard to use foods for fuel knowing that there are lots who are starving. Although it could be best if there would be potatoes enough to feed everyone and be used as a source of energy.

The problem with any oil replacement is it's energy density. We'll need oil for another quarter to half century while we perfect electric vehicles, (batteries in particular), and deploy solar and wind. I think we are on the right track, it just takes time.

Would be great if we could get the supply up!

That said, it's much more efficient to use two massive plates of metal and a big basin of salt water, than it is to fill the same space with potato batteries.
