Now, we can see the current passing through the wires and activating the digital clock. The electrical voltage and current produced by potatoes are at a very specific range. Considering the fact that each electrical device such as a light bulb or electric motor also has certain requirements to operate, the potato battery project is a very ...

With the average global price of over 2lbs of potatoes holding at $0.51, the current energy needs of poor towns and villages could easily be met. (4) Obstacles To Overcome. The University offered to give the invention away, free of charge. Despite this, the potato battery has yet to sweep the globe or make the headlines. The lack of enthusiasm ...

Did you know you could power a light bulb with a potato? The chemical reactions that take place between two dissimilar metals and the juices in the potato create a small amount of voltage that can power a very small electrical device [source: MadSci].Follow the instructions below to make a potato-powered light bulb.

The potato battery I rigged up puts out 1.60-1.80 volts so says my multimeter, but when I alligator clip it to the clock, nothing. I pulled a double a battery from a controller, and it works, but not the potato batterie (also tested the battery with the multimeter to see if the multimeter is broken, it came up right around 1.5 as well).

I don't know how much current a potato battery usually provides, but if you are using an old-fashioned VOM (analog unpowered multimeter) it may be loading the potato too much to register. If you are using a VOM, try a VTVM or FETVOM (analog meters with internal amplifying devices made to reduce load on the measured circuit) or a good quality ...
