Snow Melting Driveway – Why Don’t I Have One Of These?

I like to consider us a pretty advanced civilization.  We have smart phones, smart TVs, tablets, etc., so where the heck has this thing been my whole life?  Shoveling snow has certainly become an antiquated method of removing snow from driveways and sidewalks.  Many of us have snow blowers to ease the burden of the snow removal chore.  So why haven't we mastered this process?  Hopefully this is something we will all have at our homes.
