Storing the sun’s energy underground could help keep Canada’s roads ice-free in the winter months as a safer and cheaper alternative to plows and salt.
I’d be really curious to know how long and cold of a winter they are talking about.
For example: would this work in Saskatchewan or Manitoba where the snow starts falling near Halloween and isn’t gone until May? With regular temperatures below -20C and severe cold snaps below -40C?
I remember reading somewhere that Oulu, Finland has heated streets that stay perfectly clear and dry all winter. Though it was just a small section of the city and not on any highways or anything.

We’re part of Canada too.
Judging by the national media’s coverage, you’d never know that.

Oulu’s averages are warmer than Saskatchewan and Manitoba generally speaking. Still not a direct comparison, but I appreciate the info anyway.
They also have a lot of easily accessed geothermal heat.
It might work in regions that have natural thermal vents (such as in the mountains), but I don’t think that’s an option across much of the country.
