The Highway That Generates Electricity From Passing Vehicles

Israeli scientists have developed a method to generate electricity by using the cars passing. In addition, they announced that next month will inaugurate two such highways that will generate energy.
Experts say that the cars which are moving on a distance of one kilometer can generate over 640 kilowatts, enough energy to power 12 small cars. As the vehicles go on the road, they press some piezoelectric crystals that produce a small amount of energy.
If thousands of such crystals are placed on the road surface, can be produced enormous amounts of energy. The electricity created can be transferred to the national electric network, or can be used for heating and lighting.
Innowattech, the Israeli company who leads the research, will develop the first highway that will generate electricity in only a few weeks. The company intends to apply this system for railways.
In August, the U.S. researchers have shown that the asphalt could be a cheap source of electricity and hot water when absorbs the heat generated by the sun. Experts have conducted experiments with different compositions of asphalt and have discovered that adding some compounds with a high thermal conductivity may increase the heat’s absorption capacity and finally came at the conclusion that asphalt can be indeed a source of green energy.
