Evenin, folkses...

That bidness of the under-driveway heating was done, sorta, in Pullman, on the WSU campus. Maybe lots of places do it but I'd never heard of it before.

Pullman gets a few feet of snow in the winter and it stays for the duration. Seems that all the buildings are heated with steam from a central steam plant and all the pipes are routed through town in tunnels that run under all of the sidewalks and such.

It works really well. Snow and ice arrives in November or so and stays through February but all of the sidewalks and walkways stay melted and warm and ice-free.

Maybe lots of places do this sort of thing. But I've never seen it before.

Perfect use of the leftover steam!

When I lived in MN, I visited the U of MN campus a couple times. In addition to the radiant heat under the sidewalks, they also have an extensive pedestrian tunnel system. You can get from building to building without having to go outside.

Pretty handy stuff when it's -20° outside.
