This project got a lot of attention, but it's probably dead on arrival. As this article points out, there is so much more available space that is not being used for solar power that is also easier to maintain and use. Roads take immense abuse, and textured glass may work great in parking lots, but it would be terrible for a lot of roads. What about in places where it snows a lot? What happens overnight ? Since there is no power from the sun, how would the roads melt the ice? Are we going to draw power from the rest of the grid to heat roads? You can't plow on these roads, and salt would be awful.
Take your Solar Roadway investment and put it on to some panels for your roof. Makes a lot more sense.
