Today’s Solutions: December 18, 2025

High temperatures and minimal rainfall have left the Himalayas bone-dry. To solve the water shortage, an engineer has come up with an ingenious solution called the “ice stupa”, an artificial glacier. Melted water from existing glaciers is diverted underground through pipes that lead to the stupa. Once there, gravity pressure forces the water up the pipe and sprays it into the air. Thanks to the bitter cold, the water freezes as it falls to earth and forms a cone-shaped glacier that stores water that can be used in the dry summer months.
