How One Homesteader’s “Sun-Pipe Chimney” Cooled His Loft on the Hottest Days
On August 8, 1878, Denver recorded 105°F—tied for the city's all-time high. Nights stayed above 70°F. Frontier cabins built to hold winter heat became summer traps. Lofts turned uninhabitable.
One homesteader made a single modification: he cut a 10x12-inch grille in his loft floor, positioned directly beneath the existing stovepipe. Sun heated the black iron pipe. Hot loft air was pulled upward through the grille and exhausted outside. Cooler replacement air entered from shaded north-side gaps.
No new construction. No purchased materials. Just directed airflow using hardware already in place.
By mid-August, the loft was occupied again. His ledger recorded one line: "No more sweat on pillows."
