'Ice stupas' in Ladakh help fight water shortage and wastage
Sonam Wangchuk, the man who inspired '3 Idiots', has introduced artificial ice stupas as a way to combat water wastage and shortage problems in Ladakh. These self-building structures collect and store wasted water from streams in geometrically shaped formations. The artificial glaciers are further shaped in a way that they don't melt until late spring.
