In 1927, John D. Rockefeller Jr. began discreetly purchasing large tracts of land in Wyoming's Jackson Hole region. He used a front company called the Snake River Land Company to conceal his identity during the acquisitions. Over time, the operation accumulated more than 35,000 acres at a total cost of $1.4 million. Rockefeller subsequently donated all the acquired land to the United States government. The land was eventually incorporated into what is now Grand Teton National Park.
A hospital in Sundsvall, central Sweden, has adopted an unconventional cooling method that relies on snow collected during winter months. The snow is stored in a large, insulated facility, and its meltwater is circulated through the building to regulate temperature in warmer months. Researchers emphasized that proper insulation is critical, as unprotected snow would fully melt by mid-June. The system proved effective enough to meet the hospital's cooling needs from May through August. The findings highlight stored snow as a viable and sustainable alternative to conventional air-conditioning systems.
