Heat from underground subway station to power homes in Paris

Eco Factor: Green heating system to utilize waste heat from underground subway station to heat apartments.

Doesn’t it feel horrendously warm while waiting for a metro at the underground subway station? Well, the builders of a new housing estate in Paris have come up with a pioneering idea to utilize this waste heat to generate energy for a low-income housing building located above the metro station. The high temperature in the metro station is a result of the 100 watts of energy expelled by each passenger and heat produced by the moving trains.

The project based on geothermal technology aims to draw heat from subterranean passages and transfer it to heat exchangers, which supply it to the heating pipes that help to keep the 17 apartments warm. This unique heating system slash carbon dioxide emissions by a third compared to using a traditional boiler room. The green and innovative experimental project is scheduled for completion in 2011.
