How do people sleeping in the streets regard an Indian moon-shot?
Probably the same way American homeless regarded the moon landings.

The artificial glacier growing in the desert
In 2014 a local mechanical engineer, Sonam Wangchuk, set out to solve the water crisis of the Ladakh region in northern India.
The natural glaciers are shrinking due to rising global temperatures. For that reason, they provide far less water in early spring but then release a lot in the summer heat, shrinking even more.
Wangchuk had a simple idea: he wanted to balance this natural deficit by collecting water from melting snow and ice in the cold months, which would normally go to waste, and store it until spring, just when farmers need it the most.
“I once saw ice under a bridge in May and understood that it’s the sun that makes the ice melt, not ambient temperature,” he told CNN.
“I realized that ice can last a long time, even at low altitudes.”
The ice stupa is created using no power or pumps, only physics: “the ingredients are a downstream, an upstream and a gradient,” says Wangchuk.
