Earth Lights 5In this video I show how to hookup a second transistor in the base circuit to shut off the earth light during the day. Also I will show you a simple earth cell and what I found to use to enhance power level of these cells.What I found can be bought in a grocery store in the spice section, it's called Alum. You only need a little bit added to water and it does not seem to eat the magnesium away.John B
