Erm, ok, so what is gravitational energy?
Gravitational energy is often harnessed and used as a clean power source for consumption.
When the grid requires power, this process is reversed.
The mass cars proceed downhill with the electric motors operating as generators, converting potential mechanical energy into electricity.
It can lower operating costs, including the cost of diesel, and eliminate rail system carbon emissions.
