Human Bodies Waiting Below for Paris Metro will Heat New Apartment Complex

Interesting idea!
I have been in NYC many New Years Eve's and have stood above the subway grates for warmth.
It's about time someone thought of this.
BTW for those that do not know how the system works, air never gets circulated through to the new apartments. The heat exchange takes the heat from the air and transfers it to another medium, whether it is water of fresh outside air. So your bio-terror fears should not be indulged!

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.

Soon they will be putting coma victims, in hospitals, into pods, to generate electricity!
Sorry, this made me think of the Matrix!

So true. S&F It is ingenious.
