DIY Earth Tubes
Discover the forgotten science of earth tubes (ground-coupled heat exchangers). In this video, we show you how a simple $40 PVC pipe buried underground can capture the earth's constant 55-degree ...
Earth tubes ( earthtubes , or earth -air tubes ) are underground tubes that use geothermal energy to cool or heat temper the air for your home. It works like cheap air conditioning because you can build it yourself for several hundred dollars and it is FREE to run (no electricity needed).
Why Install Earth Tubes for Natural Home Cooling
