    California is well known for its car culture, traffic jams and smog.

    All of those cars and trucks consume energy, but soon they could be made to create energy as well, with small generators called piezoelectric devices.

    When pressure is applied to piezos, they produce electricity. So if piezo devices are embedded in the pavement, every passing vehicle would create voltage.
