I recall seeing that it is even illegal to heat a driveway or
sidewalk, but I sure don't know that for a fact. (could be some
leftover trivia from the energy crisis) To operate it, I'd say
you'd
have to hit the lottery or be the CEO of a major corporation. A
big
snowblower would pay for itself in a year.

I would not be surprised if it is illegal in some locations. We
have
them were I live, including government buildings.
Why in the world would it be illegal?
