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