Added: 2026-05-25

[00:00:00]You're standing at the mouth of a tunnel that runs underneath an Amish farmhouse in Holmes County, Ohio. No wires, no compressor, no thermostat, and the air coming out of it is 55° in the middle of August. This $300 system cools any home to 55° using nothing but the earth beneath your feet and a fan that draws less power than a light bulb.

[00:00:22]The Amish have been building it for 200 years. The cooling industry has known about it since 1930, and in 1930, they made sure you would never find out. So, I went back to Holmes County, and what I found underneath those farms is the same physics the Persians used to store ice through 120° desert summers 2,400 years ago. And yes, this works even if your house was built 50 years ago.

[00:00:57]Summer, winter, doesn't matter what's happening above. Oak Ridge National Laboratory, that's the Department of Energy's own research facility, measured it city by city.

[00:01:06]In Chicago, the ground sits at 55° year-round.

[00:01:11]In Atlanta, 62. Denver, 58. Phoenix, 67.

[00:01:18]Minneapolis, 52.

[00:01:20]And in Holmes County, Ohio, right where those Amish farms sit, the soil temperature stays between 54 and 56° every single day of every single year.

[00:01:31]It never changes.
