If there is no light (because it is blocked by the snow), there will be no additional heat.
Yes, but it can prevent the snowfall to some degree in the first place. Won’t work in Maine, I’m sure, but I’d bet most of the snow that affects most of the people in America falls at over 27 degrees.
However, if you maintain it, it may be easier to eliminate the snow because it’s half melted under the heat. It’s about reducing the labour, not the elimination of labour.
If you want to eliminate labour, that’s what children and children are for.
One problem with aluminum is that, although it heats up fast, even a perforated version would give little or no traction. You could turn that snow into a sheet of ice depending on your outdoor temperatures.
Most of us have black asphalt driveways... once they’re covered in snow it doesn’t matter what the color is, metals and everything else have their own heat retention measures, so its not solely the black paint.
sunlight penetrates snow... it is a miraculous thing... like it was planned that way.
just make the concrete darker and save on painting and clear coating...
bam.
