In 20 years do not be surprised if shingles in your roof are producing solar power. And the paint on your car.
We are only at the very beginning of this technology. Yet another side benefit to the billions spent on space exploration in the last 50 years.
The day will come when electricity is so cheap that it will not even be a household in the budget consideration. That might take 50 years but it will happen.

I have no doubt that much of this will indeed happen.
With shingles in the roof or paint on the car, the power has a ready target (house or, well, the car).
The problem with the photovoltaic roads is not one of producing the energy, but harvesting it.
Also, it is being touted for the ability to use built-in LEDs to alter traffic lines at a moment’s need – not going to work in daytime….
New technologies are awesome and exciting – but we need to use reason.
