When you have money, you can do interesting things. Race car driver Mario Andretti has an Italian Villa style home with a block driveway - can't really run a plow on that as it would rip up the blocks. There are water pipes under the block - in Summer, the heat is used to heat the water in his pool. In winter, warm water is circulated through the pipes, and in a light snow, it's enough to keep the block warm enough that the snow never sticks. But get a heavy snowfall, and it's game over, it can't keep up, the snow eventually cools the block enough to be able to accumulate, and it gets all covered like any other road. Not sure what they do then - keep circulating the water until it melts, or end up hand shoveling it all, or use a snowblower or plow with a generous clearance setting at the bottom (since the warm water can probably easily melt an inch of snow off, set the blade high to avoid scraping any brick, and let the heated block take care of the rest).
It's partially solar - he has solar panels that heat the water - but there's no way to get enough heat just from that. I've driven past during light snow - other driveways and sidewalks are covered, the main road is not due to traffic, and neither is his driveway.
I do like the idea of putting a standard solar panel installation on the roof there and compare the output to the Solar Freakin Roadways blocks. Heck, just a single panel could probably outgenerate those silly things.
