For a concrete drive, I would think that one could cut grooves with a
saw, insert heating wires, and seal up with sealer. This would be like
how they put sensor wires in for traffic lights.


I'm sure it can be done, but it would also be like trying to heat the entire
planet as the heat will go down as well as up. I can't imagine the cost.
