How To Make An Earth Battery
I knew from watching a documentary a few years ago that the ancient folks of Baghdad made batteries from earth. They are called the Baghdad batteries and have been dated to over 2000 years old.
I don’t know why, but the documentary came in conversations so I decided to do a little research on a more modern approach to the old school earth battery. With as something as simple as an old ice cube tray some soil a few bolts and copper wire you can get about 5 volts of electricity. This is enough to power a few LED lights, calculators and if you are really tech minded even a mobile or USB device.
