Ramp generates power as cars pass
Electro-Kinetic Road Ramp
The ramps generate up to 50kW of power
A road ramp that uses passing cars to generate power has been developed.

Dorset inventor Peter Hughes' Electro-Kinetic Road Ramp generates around 10kW of power each time a car drives over its metal plates.

More than 200 local authorities had expressed an interest in ordering the 25,000 ramps to power their traffic lights and road signs, Mr Hughes said.

Around 300 jobs are due to be created in Somerset for a production run of 2,000 ramps next year.

Plates in the ramp move up and down as vehicles pass over them, driving a generator.

"The ramp is silent, comfortable and safe for vehicles," Mr Hughes said.

Depending on the weight of the vehicle passing overhead, between five and 50kW can be generated.

The prototype was created and tested at Hughes Research unit at the Westland Helicopter base in Somerset, at a cost of 1m.

The concept has been developed by Dorset-based Mr Hughes over the past 12 years. He recently approached councils across the country with the final patented project.
