Rechargeable Cell
This is a homemade rechargeable cell that will charge in either direction —like a capacitor. The cell is made using two non magnetic stainless steel condiment cups. The insulator is common kitchen paper towel. The electrolyte is Mg S04 (Epsom Salt) and tap water. Magnets are used to hold the cell tightly together. A simple reed switch pulse motor is used to show how the cell can be charged in either direction. I also show how the cell can ‘rebound’ from a dead short –in either direction. At the end of the video I briefly charge the cell using a 9v battery and show how the cell will power the motor. A 5 second charge from the 9v battery will run this motor for 15 minutes. This is not a very good energy storage device but it is interesting.
