Hydrothermal Cooling- Latest technique to save power

Toronto, one of the largest business hubs in Canada is saving 61 MW of electric power by a novel product of technology - Hydrothermal cooling. The technique uses water of Lake Ontario to run air-conditioning systems. Three large pipes have been run into Lake Ontario, to a depth of 83 metres. The water is piped to a filtration plant and then to a heat transfer station on the mainland. Here, the 'chill' is transferred to another closed loop consisting of smaller pipes that supply the towers of the city's financial district.

As many as 36 buildings in Ontario are using this technique to run their air-conditioning systems. Not only does it save power, space of cooling towers which used to placed on roofs is also saved.

These kind of innovations not only mark the utmost in technological skills mankind has achieved but also its increasing concern towards a greener world.
