Solar Earth Climate Solutions
The "Climate Battery" a type of geothermal heating system was developed by Jerome Ostentowski and Michal Thompson; inspired by the work of John Cruickshank.
These heating systems are fairly easy to build requiring inexpensive materials. A climate battery utilizes a fan to force the heat from the apex of the greenhouse structure into the soil in the heat of the day, both cooling the air and removing humidity. At night the fan, connected to an automatic thermostate reverses to warm the green house.
Solar Earth Climate Solutions will custom design and install your green house with a climate battery.
