Tubewell Operated by a Windmill
A grassroots innovation by two brothers from Darrang district in Assam, who had just graduated from high school has
proven to be a blessing to the salt producers of Little Rann of Kutch in coastal Gujarat. Windmill-powered pumps have
replaced diesel pump sets, on which they were previously reliant, to pump out seawater for salt production. This has
resulted in a 40% reduction in operational expenses. Their low-cost alternative was constructed from locally available
bamboo, tin sheet, strips of old tyres, and an iron shaft, which was then attached to a hand pump.
