While most of us are taught to rely on expensive mechanical compressors to survive the summer, every home in America actually sits on top of a free cooling system. I’ll explain the engineering behind the thermal battery effect and why the soil 6-10 feet below your yard doesn't care what season it is. I also uncover the "Code Wall" that keeps this technology out of reach for many Americans. From the ancient Yakhchals of Iran to modern passive house standards in Germany, I explore why the US HVAC industry spends millions on lobbying to keep you tied to the grid. If you’re interested in sustainable living, slashing your energy costs by 50%, or building your own geothermal cooling setup, this is the blueprint you've been looking for.
