The road system utilizes a series of hydraulic pressure devices to capture and store waste energy from cars travelling on the braking sections on the highway. It then uses that energy to generate electricity.
The system’s key components include piston plates, energy storage devices, and generators. The pistons are depressed by travelling vehicles and the energy is stored and turned into electricity.
The system is reported to offer up to 30 to 40 percent working efficiency.
