How To Build a Climate Battery - Day 3 - Construction In Passive Solar Greenhouse

In this video we continue the process of building the climate battery for our new passive solar greenhouse. Climate batteries also called GAHTS and subterranean heating and cooling systems store energy in the earth when there is a surplus of heat in the greenhouse for later use.

We spent most of the summer performing thermodynamic analysis on our greenhouse to determine if they even worked and to our amazement they do. In fact our analysis showed that they have the ability to store energy seasonally which was better than I was expecting.

Our model anticipates that we should be able to keep our greenhouse above zero until January 15th of most years without any fossil fuels to keep it heated. This should provide us with 3 seasons of robust food production with minimal costs.
