The two-kilometre-long (1.2 miles) stretch of highway, situated in
Jinan, could charge electric cars as they are travelling on it.
The two-lane road could also warm itself up in sub-zero weather to
melt the snow on top so drivers could drive on it more safely.
Formed with special weight-bearing solar panels, the road can hold medium-size vans and has strong friction.
Once it’s completed, the highway would be connected to the power grid so it could provide electricity to the city.
The solar highway is formed with three layers.

The top layer is paved with the so-called ‘transparent concrete’,
which is said to be as strong as the traditional road-surfacing
material, asphalt concrete.
The middle layer is the power-generating layer consisting of solar panels.
The bottom layer is the insulation layer which separates the photovoltaic system from the damp earth.
