WE already harvest the power of the sun and the wind. Soon we may also harvest the power of potholes. A new type of shock absorber under development by the Levant Power Corporation converts the bumps and jolts of vehicles on rough roads into usable electricity.

Usually, shock absorbers dissipate the energy of bouncing vehicles as heat. But the new shocks can use the kinetic energy of bounces to generate watts, putting the electricity to use running the vehicle’s windshield wipers, fans or dashboard lights, for example.

The devices, called GenShocks, can be installed both in ordinary and hybrid vehicles, lowering fuel consumption by 1 to 6 percent, depending on the vehicle and road conditions, said Shakeel Avadhany, chief executive of the company, which is based in Cambridge, Mass.
