What does an Engineer do?
Find a solution to a problem.
Let’s dive into The Story of an Engineer in Ladakh, India to find out what it takes to be an engineer.
The inventor of ice stupa, Sonam Wangchuk, had a problem which he wanted to solve and help his community.
Problem: Farmers in Wangchuk’s hometown were facing water shortage during farming season due to climate change.
Inspiration: While pondering on this problem in 2013, Wangchuk observed that ice, even at a low altitude and the peak of summer in his hometown, stayed frozen in the shade of a bridge.
Solution: This gave rise to the Eureka moment when Wangchuk realised that he could help villages freeze water in winter for use in spring by erecting a cone shape ice stupa with steep sides that has minimal exposed surface area of contact with the sun.
Science Concepts Applied:
- Exposed Surface Area of contact
- Fluid Dynamic: A fluid in a system always wants to maintain its level.

The Science behind the Ice Stupa:
The ice stupa is created using no power or pumps, only physics: “the ingredients are a downstream, an upstream and a gradient,” says Wangchuk.
“A cone is very easy to make with ice, because any dripping naturally forms a cone underneath — icicles are inverted cones,” says Wangchuk.
The Math behind the Ice Stupa:
But a cone has more desirable properties: “It has minimal exposed surface area for the volume of water it contains.”
That means it melts very slowly: the prototype, 20 feet tall and containing 150,000 liters of water, lasted from winter until mid-May, just when water is needed for irrigation, while all the surrounding ice on the ground had gone by the end of March.
