I thought that I would try to make an Earth Battery. I managed to do this with some items that were in the garage. By the end of the video I had 15 Earth Batteries putting out 8.5 DCV. This managed to light five LED at the end of segment(I am holding three,other two are on the bench) This did allow me to see in a pitch black garage, wich is hard to show in the clip. If you know how I can step up the volts please let me know…oh yeah…ZEER Pot Fridge not a ZEEK Pot Fridge…brain farts eh !!!
