I can’t believe someone else has had the same idea as me! Thats just super. Speed bumps are everywhere in Norway. In the city of Bergen alone there are supposed to be over 2300 speedbumps. I have no Idea how many cars drive over them each day, but if it was 100000 hits per day (it probably is ten times that) at 10kwh pr passing, that would generate 1 million kWh. Pr day! And that is a conservative estimate! At least the city of Bergen would be able to generate enough to run all its street lights and probably quite a few buildings as well. Got to do some more research on this now…
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.
Underneath the Electro-Kinetic Road Ramp
Inventor Peter Hughes spent �1m developing the ramps
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.
