How He Stacked Hay Bales Around His Cabin Three Layers Deep—And Never Needed Firewood Again

A frontier man with no firewood left stacks hay bales around his entire cabin three layers deep on all sides and over the roof, leaving only the door and chimney exposed. The hay traps so much heat from his body and a single candle that he stops needing his stove entirely. From the outside the cabin disappears — it looks like a giant haystack with smoke coming out the top. The cheapest warmest shelter on the frontier.
