Here is a geothermal air conditioning system you can install for about $1,000 that only uses about 100 watts to operate 24/7 cooling your house, garage or greenhouse. You can watch the video at www.youtube.com
The Simple Tek YouTube channel has lots of interesting content on solar, heating, cooling, greenhouses, and more.
Awesome, thanks! I love appropriate technology. Elegant and simple… efficient and effective.
