Does Anyone Make One of These?
The TrailBlazer's 4WD has failed with a very useful icon: a wrench next to a simplified drivetrain. In the meantime I am looking for a better solution to my aspirational glacier. We get a fair amount of sun when it isn't actually snowing, and even enough when lightly snowing to produce photovoltaic output. My thought is a small solar panel and a small storage battery feeding a resistance heating unit abutting the edge of the asphalt. It doesn't have to heat up all the asphalt; once one section is clear, the asphalt absorbs infrared and soon, the rest of the asphalt engages in sympathetic magic, and melts the snow. Of course, a thermostat shuts off the coil above freezing. Put a few of those along a silly long driveway like mine, and in mild snow conditions, you have a clear road. In severe conditions, with a day or so of full sunlight, it clears.
