Heat From Underground Subway Station To Power Homes In Paris

If you often take the train at the underground subway station during rush hour, you’ll probably have noticed that it’s incredibly hot and stuffy. The builders of a new housing estate in Paris have come up with a rather innovative idea to harness this waste heat and use it to generate energy for a low-income housing building located above the station. The high temperature in the station is a result of the energy expelled by each passenger and heat produced by the moving trains. This unique heating system aims to cut carbon dioxide emissions by a third, compared to using a traditional boiler room. This experimental project is slated to be completed in 2011.
