Earth Tubes Work. Here's What Happens in Year Three.

The physics of earth tubes is real. What nobody films is what the pipe looks like in year three. A video with over two million views shows how a buried pipe cools a house using nothing but soil temperature. It is correct. But it was filmed at install, and the part that decides whether you should build one happens about thirty months later, when condensation and biology catch up. This video walks the full timeline. The soil temperature data from Kusuda and Achenbach's 1965 NBS study. The dew point arithmetic that guarantees condensation in humid climates. What biofilm looks like inside a pipe that was never given a cleanout port. And where earth tubes still make sense, because in the right climate, they genuinely do.
