Portland Cement Battery.ASF
This shows a battery made using postland cement and Pacific ocean beach sand. The mixture is in an coke can and is rock hard. Tap water was used and the setup time was a couple of hours. The battery is 18 hours old at the time of this video time and is producing 1.25 volts. I show it here running a small pulse motor. This was a stepping stone project to help me learn how a real “crystal battery” works. I consider this “cement battery” a purely galvanic battery until it completely dries out which could take months. It is the final power observed (if there is any) that is of real interest. Many thanks go to John Bedini for sharing his knowledge on true crystal batteries.
