This $300 Tunnel Keeps Your Home 55°F Forever. Why Is It Banned in the U.S.?
This $300 Tunnel Keeps Your Home 55°F Forever. Why Is It Banned in the U.S.? 54 degrees Fahrenheit. That is the temperature sitting beneath your foundation right now. Constant. Unmoved by blizzards, heat waves, or anything happening above ground. While your furnace fights to lift freezing winter air to 68 degrees, the ground is already holding 54 for free, in silence, and it has been doing so for thousands of years. The ancient Persians knew this. So did the Romans. And modern Germans are legally building systems that tap into it for around 300 dollars in materials. #offgridliving #sustainableliving #persian
