Speed bumps are not really something you would be raving about if you happen to own a vehicle, but the latest “models” in London are all set to change that conventional perception.
The new speed bumps designed by Peter Hughes and will reap free energy every time wheels roll over them. With a cost from £21,000 to £55,000 depending on size – yes, they don’t come in cheap, the metallic knob-like humps manage to earn their value back in just about an year.
Designed to tap the kinetic energy generated by vehicles that roll over constantly, the new technology uses the weight of the car to displace the metal plates underneath and set the wheel rolling to convert mechanical work into energy. Producing between £1 and £3.60 of energy an hour (each) for up to 16 hours a day, the energy will be used to power up street lights and road signs for a mile long.
Some £150,000 of funding has already been approved by the city council, so expect to see them pretty soon while you drive around London. [via EcoWorldly]
