What a HOT battery!
Jalapeno's make for a good battery. In this example
I used a copper wire and a regular steel nail. You can get voltage just
by probing the pepper with a sensitive meter {from 0 to about 2 volts.}
Although we get about a half a volt, the current is only about 2
to 4 milliamps.

What
a Lemon!
This is the best smelling battery I have tested.
This is a good metal cleaner also. {see below} Once again using the same
copper and steel as bi-metals. As with the jalapeno, you can get voltage
without bi-metals but they are better for these tests. The voltage is better
than the current with the lemon. The acid in lemon juice, vinegar, Jalapeno's
all make good electrolyte for batteries.

What a metal cleaner!
These metals were oxidized before the lemon test.
You can see the metal shine where it was inserted into the lemon. This
might come in handy when cleaning coins etc. when you can not use abrasives.

You call this a battery?
This was a test using the length of the bi-metal
exposure to determine voltage and current. Solutions such as salt water,
vinegar, jalapeno's were tested. The current of this battery is about 10
MA. As you can see ALL of these test use household items. Carbon, Zinc
and Copper are used in many batteries. I'll bet you didn't know you
could charge a potato! Some say the eyes look better after a charge.

Voltage between Metals.
The best battery I made used Galavonized pipe, and a copper pipe using
jalapenos for the electrolyte. The voltage per cell is 1.2 volts and a
current of 800 milliamps. Store bought batteries are better, smaller and
have more current for the size, if they are available. Bringing two dissimilar
metals close together without touching will produce a small voltage and
about 200 Microamp..
