California is testing whether its heavy traffic can produce not just emissions and air pollution, but electricity. The state’s Energy Commission says it will spend $2 million to examine the potential of using piezoelectric crystals embedded under asphalt as a way to send the energy created by moving cars to the grid.

The state’s Energy Commission says it will spend $2 million to examine the potential of using piezoelectric crystals embedded under asphalt as a way to send the energy created by moving cars to the grid.
The crystals generate energy when compressed by the weight of moving cars, but tests of the technology at larger scales have failed or been canceled in Tokyo, Italy, and Israel, according to the Associated Press.
