Update (January 26, 2017): I made this video in early 2016. Since then I built a new greenhouse ( • $100 Greenhouse! Wood ... ), added a geothermal system to it ( • Vertical Geothermal Ea... ), and built a compost-based heating system ( • Heat Greenhouse with H... ).

Most vertical (well) geothermal systems circulate antifreeze down-hole for heat pumps. The "Earth Tube" system is a much simpler approach - blower circulates cold/hot air from the surface to underground, usually via buried plastic tubing. All the earth tubes that I'd seen previously were "horizontal" systems, meaning buried in trenches dug by a backhoe. Here, I drill small holes by hand with a Seymour post-hole auger. I show how such a system can achieve excellent efficiencies - coefficient of performance exceeding 15. In part 2 ( • Vertical Geothermal Ea... ), I describe how I constructed my pilot system
