The body heat of about 250,000 commuters in Stockholm’s Central Station is now being used to warm a building across the street. Engineers and designers in Sweden have figured out a way to harness the excess heat energy from the activity of people who pass through the station each day. The technology works through the use of heat exchangers installed in the station’s ventilation system that convert the heat into hot water. The technology has been around for a while. The difference is the water is then pumped to the heating system in a nearby building to keep it warm.
