Ramp creates power as cars pass

The Electro-Kinetic Road Ramp generates power each time a car drives over its metal plates.


The plates move up and down as vehicles pass over them, driving a generator. Depending on the weight of the vehicle passing overhead, between five and 50kW can be generated.

More than 200 local authorities in the UK have expressed an interest in ordering the ramps to power their traffic lights and road signs.
