I am building the battery system from old burned out lap top batteries. I have 7000 watts of the 21000 watts I need already, that I salvaged and tested.

They are being stacked into 24 volt sticks at 60 watts each.

The Earth Battery is a loop of pipe buried in the ground deeply enough that it stays at 58degrees F. In the winter it will warm the air, in the summer it will cool it.

The wallipini is a greenhouse that is buried underground to regulate temperature.

you sound really enthusiast about your work , that is good , I feel people will learn a lot from you x

As I build these systems, I will post them on steemit. It may help others become independent too!
