More benefits from Paris Metro

Heat exchange is a wonderful thing, often seen as a windfall by engineers. In this story on a Paris Metro station, we see that the heat generated by milling bodies waiting on a subway platform can be tapped to heat 17 apartment buildings.

One more reason to get that ridership up. But don't pick them up to soon. But don't let them wait too long either.
