Generating Electricity from Passing Cars
The first practical test of an innovative technology to generate electricity was conducted by Innowattech and the Technion - Israel Institute of Technology.The test was accomplished by drivers passing through the Hefer intersection,Israel, without even realizing it.They generated electricity while driving over a ten-meter strip of asphalt,underneath which lie generators capable of producing some 2,000 watt-hours (Wh),the power was relayed to batteries situated beside the road.
The technology is based on piezoelectric materials that enable the conversion of mechanical energy exerted by the weight of passing vehicles into electrical energy. As far as the drivers are concerned, the road is the same.Edery-Azulay added that expanding the project to a length of one kilometer along a single lane would produce 200 KWh, while a four-lane highway could produce about a MWh - sufficient electricity to provide for the average consumption in 2,500 households.
If the pilot test is successful, the project is expected to be expanded. Generators will be situated in one-kilometer strips along Israel's highways.
