‘Swing’ pump to fetch water and produce electricity

An alumnus of BIT-Sindri in Dhanbad, SN Singh and two others invented a unique swing which is used to fill the water tank on the roof as well as to produce electricity by converting mechanical energy into electrical energy.

IIT Kharagpur praised Singh, along with principal of ITI Kalpatru in Patratu, Ramgarh Sanjeet Kumar, and technician Bhagwan Sharma for this invention.

The spring pump, which took the trio one year to make, has been installed at a school in Ranchi where students enjoy swinging, which fills up the school tank without the need for electricity.

Kumar said it cost only Rs.10,000 and can also be used to generate electricity and help farmers irrigate their fields.
