Crazy Homesteader Wraps Cabin in Metal — Stays 55° Warmer While Neighbors Freeze

Описание: Montana, 1947. When Frank Morrison wrapped his log cabin in a surplus military Quonset hut, every builder in the valley called him crazy. Then winter hit -38°F... and his "insane" design held 55° more heat while using 1/5th the firewood. This is the true story of how one desperate engineer proved everyone wrong and changed frontier heating forever.
Frank Morrison built a solid log cabin in Montana — 12-inch spruce logs, fieldstone foundation, steep roof. By frontier standards, it was respectable. But his first winter (1946-47) taught him the brutal truth: wind doesn't just chill air, it strips heat directly from walls through convective cooling. His family burned through 4 cords of pine in January alone, feeding the firebox every 3 hours, and still woke to frost on interior walls. The cabin stayed around 45°F on good days. His daughters slept in winter coats.
Drawing on his experience building military Quonset barracks in the Aleutian Islands, Frank had a radical idea: wrap the entire cabin in a 20-foot Quonset hut, leaving a 2-foot air gap on all sides. The metal shell would block wind before it touched the logs. The air gap would act as a convection barrier — like the dead air in a double-pane window.
Total cost: under $120. Build time: 3 weeks.
The neighbors thought he'd lost his mind. They called it a "tin coffin," a "sweat box," predicted it would rot his logs with condensation and collapse under snow load. Even his own brother, a professional carpenter, said it looked "desperate."
Then the winter of 1947-48 hit — one of the most severe in Montana's 20th-century history. For 23 consecutive days, temperatures never climbed above zero. Nighttime lows reached -38°F with wind chills below -60°F.
While neighbors burned 2+ cords of wood per month to maintain 40-42°F indoors (with families sleeping in coats), the Morrison cabin achieved:

63°F average interior temperature (vs. 42°F in standard cabins)
55° more warmth than neighboring cabins
0.75 cords of wood per month (vs. 2-3 cords in standard cabins)
70% less firewood consumption
Children playing in cotton dresses while outside was -38°F

The county extension agent who'd warned the system would fail came with a calibrated thermometer, determined to prove it wrong. He measured a 99° temperature difference between inside (64°F) and outside (-35°F). He wrote in his notebook: "I was wrong. Completely wrong."
