My issue with it is the scaling. They had a test installation in sidewalk which proved to be woefully inadequate. Yet the pushed on, largely unchanged. They took two things which have significantly different requirements and tried mashing them into one. Solar panels need to be oriented towards the sun to maximize energy, and need to get as much sun going through the glass to the panel as possible. You basically end up multiplying many variables together to get the end efficiency, and we're actively degrading 3 by a significant degree by adjusting the glass/plastic to withstand the weight of cars and semis, scratching the surface over time with the dust and sand, and mounting them flat. Roads need to be cheap to install, need to be long lasting, and need to assist vehicles in stopping quickly. I'd love to know the difference in stopping distance and coefficient of friction between this and traditional roads.
