Leave it to the French to do something that’s undeniably awesome yet leaves us feeling somewhat uncomfortable at the same time. An experimental heating system, being installed in a public housing project in Paris, will use the warmth generated by human bodies in a nearby Metro station to heat the building.
The system will tap the caloric heat emitted by the passengers milling about below ground as well as the heat generated from trains moving on the tracks, and funnel it through an underground corridor to heat exchangers that will push warm air through the building’s pipes. The system isn’t stand-alone, but will be supplemented by district heating.
