When the Cold War began, engineers needed bunkers that could survive not just bombs — but decades underground. What they discovered was a ground pressure and heat layering technique that made their structures last longer and stay drier than any survival shelter before or since.
This episode uncovers the Cold War shelter hack that modern preppers completely overlook — the method that stabilized temperature, redirected humidity, and resisted collapse even without maintenance.
🏗️ What You’ll Learn:
The Cold War airflow design that stabilized underground shelters
Why air layers beat thick insulation
