aluminum can and copper wire batterys

[The Observer]

Hello,

For the 4th I created the first in a series of Lamps hopefully powered by a Penny Pill Jar Setup.

Being my 1st Step Toward Energy Independence... This will be a 4th of July to Remember !

The goal is to have a Joule Thief do the lighting, but the  light's circuit will have to be a start.
   -note ... the  light's circuit has no inductor yet lights 1 bright LED w/ 1.2 V NiCad
            ... the Pill Jars (2.4 V in series) do not work directly in solar light's circuit, but light a JT just fine (brightly)

This lamp is going to be powered by both the ambient light in the room and the Pill Jars.
It has already changed the world as I have not turned on the lights I normally would have tonight.  ;o)

Best Regards,

@The Observer
With respect to your Post #60,

Good going!  Reminds me of my steel/aluminum can water cells.  I need a few more parts to attempt to repeat your experiment with what I have handy.
(I don't have the software you have to be able upload data to OU's server, but I can reference the 'Web wherever possible.)

@old man
I hope it is ok with you to post this in your thread.
I have made what I will call my “RX Water Battery”.
The first 2 were made 5 weeks ago â€" joined - and are putting out a constant 1.3v unloaded.
RX Containers â€" trash
Ground wire from romex, 15 inches - recycled
Galvanized steel wire, 18 inches â€" pennies
LED (20 asst from RS) â€" not expensive
Squealing like a little girl when it actually works â€" priceless
Below is a pic of my latest test â€" after approx 6 hrs I had to remove 3x5mm red leds, 1x3mm red led is still shining brightly with no sign yet of quitting.

Having this much fun should be wrong!

@all

Guys have a look a this fire from a potato.

One potato emptied in the middle filed with salt and toothpaste , 2 wire they seem the same material , so i don't thing galvanic here , 5 minute and voila enough current to start a fire , its probably a trick but if real really worth looking into .
