I have tried different solutions, everything seems to work, no matter what the mix, but today I tried it with just plain water and it worked. STRANGE!


K, so now this battery works even with water. I get 1 volt dc out of it. Time to make something bigger. Stay tuned!! This will be neat.


P.S. Still rechargeable with water?? WeirD!

AHHH HA!


Galvanic currents are generated by two dissimilar metals immersed in water. If they are in close proximity to each other they will generate a voltage potential.


Water has resistance to current flow, any form of acid or chemical can either increase or decrease the electrical resistance of the water. This solution is called an electrolyte.


Maximizing the size of the plates should also increase the current flow and voltage.

  iFred,

     We used to run crystal radios from a bowl of water back in the late 60's.  Same method using dissimilar metals.  Use larger plates and your amps will come up.  If you burry 2 sheets of metal in your back yard you'll be able to charge your Ni-Cads fairly quickly as long as the ground is moist.  If the power drops off simply turn the sprinkler on.

     Mount a microwave transformer about 3 ft from the power utility line... tons of free energy ( don't get caught... its not legal ).  String a wire to the top of one of your towers down to the ground.  Connect a one wire circuit at the bottom bingo free energy... ok not really free but its free to you... the power fluctuates but it will charge batteries...  also if you wind a coil around a flourescent tube and connect it to the wire you have a lighted pole.

     Energy is everywhere, just need to harness it!!


Have Fun

this will also work with RF energy from a nearby radio station, using a tuned circuit you can extract small amounts of energy through the antenna (you must be very close to the station antenna like 1/4 mile or less)

Are you using the hard drive Discs as they are with the iron oxide coating on them. Or are you modifing them in any way ?

My son and I made batteries 2 weeks ago.


Use 1/2c water, 1t vinegar, copper wire, galvanized nail. Drill 2 holes in popcicle stick, put nail and wire through it. Place popcicle stick over glass container with water/vinegar in it so both  nail and wire are in the solution. Hook voltmeter, + to copper and - to nail.


One made about 0.8v. We made 2 in series and the volts added together and we got about

1.6V.

Does anyone know how to build a lead acid battery that can be used for homebrewed wind power applications?
