Giant Storage Battries

(1/2) > >>

   Was just on YT and saw this video about a gent that made a giant battery, aka 55gal plastic barrel size. It was made with two lengths of copper pipe with a tubular magnet seperating the coiled up tube. Specifics are a bit lax but wanted to pass this around to see if this is correct or just more YT junk.
   Starts out with 5 meters of copper pipe about 3/4" cut in half. Sleve magnet (?) with both ends inserted. Other ends are taken out to the top for the connections. Suspended in the barrel, then filled with honeycomb charcoal broken up. A spout to fill up with rain water. Then charged for 5 hours. Shows to have a very good amp and voltage rating.
   This could be a great way to store solar out in the boonies for the off grid guy at a good price.

I would like to get some serious replies on this idea. Not sure on the life span of this idea but easy to get parts and make. Earth friendly too. Reuseable container to make more with. Think the copper surface area will govern voltage and amps available.


This battery ist Just not possible to do this way...
You could only charge this up to about 1 or 1.5 Volts, because the
2nd dissimular metal is missing...So there is probably a hidden power source inside the drum...
And charging it up would not work,
Cause it can not store the energy this way.

If this would work, it would defy all battery and Supercapacitor theory...

  Many thanks for the corrections here. Thought it was one of those to good to be true YT vids. So wished they would go  take an areonotical fornication with a rotating pastry.
Wastes so much time.

Wait a minute, charcoal is mostly carbon, isn't it? Why wouldn't a carbon / copper battery work?

Easy enough to make a small one to test the idea.

But what's with the magnet? What is that supposed to do?
