A two-member student team from Indian Institute of Technology Kharagpur have come up with an innovation of a cooling tanks inserted into walls.

These water filled cooling tanks within walls can be an effective substitute to air conditioners and lead to a 50 per cent reduction in cooling cost.

The concept is India’s entry in the five finalists of Shell Ideas360 audience choice awards.

Team Takniquee comprising Sahashranshu Maurya and Somrup Chakraborty of Department of Geology and Geophysics at the institute has proposed a cooling system called passive solar water wall which revolves around a rectangular water tank fitted into a wall.

Maurya said ACs contribute to about 35 per cent of total household electricity consumption and produces 1.5 tonnes of carbon every year.

The water is heated and passively circulated keeping the inner wall relatively cool, reducing the air temperature and the need for air cooling systems , Maurya said in the pitch for the awards open to voting by audiences.

“For a basic set up, an initial investment would be about a lakh of rupees. The design would evolve depending on the architecture,” he said.

“A large number of ACs contribute to the increase in local urban temperatures. The efficiency of the ACs depend upon the temperature difference they are trying to maintain. They are creating the very problem they are trying to solve. Also consider the scenario that the global average temperature is increasing. The number of Acs in the market is going to sore. Is that the real solution?” the team posed in their pitch.
