Waayy outside the box

I like it. There's all kinds of potential benefits, but one problem I see without giving it much thought is the fact that the ground tends to shift, move, sink and heave - especially in colder climates. Glass may be easily hard enough, but it sure doesn't like to flex. I suppose a grid system of flexible joints could be devised, but up pops that nasty "cost" thing again.

That is an interesting idea and could work. Buzz pointed out some of the potential problems and there is one other that they will need to overcome that I have seen happen around here with solar panels. If they get dirty, that tends to cut down the efficiency a lot, and with the rubber tires there is going to be rubber marks and dirt. Also the replacement of sections of panels would have to be worked into the road as there are going to be some get broken or just go bad.
