Graphite-Paper - Aluminium-Foil galvanic cell with 1.7 to 1.92 Volts

[hartiberlin]

Hi,
here is a video of my new test cell with
graphite paper and alufoil generating up to
1.92 Volts.

It can drive drirectly a red LED.

Here is the first video of a few more I already made,
but must still edit.

Youtube is still working on the HD version to render and convert,
so come back later to see it in HD.

Regards, Stefan.

Stefan:

Nice video.  How long will this effect last do you think?

Nice work.

Hi Bill,
as long as the Alufoil will last.
You just need to change the Alufoil from time to time.
The graphite paper is not consumed.
If you build it this way, that the layers of alufoil and graphite paper are closer, it will also have more current and can be used to drive a Joule Thief.
Regards, Stefan.

This kind of reminds me of a regular 12 volt battery, except you are using caustic as the electrolyte.

This does give off hydrogen gas constantly though, and you won't be able to stop that until the aluminum is completely oxidized and consumed.

Hi Stefan.

have you tried using two different forms of carbon as a battery, 1. Graphite, 2. Charcoal, add an electrolyte and see if a Galvanic reaction takes place?
