    Turning traffic into electricity

    Turning traffic into electricity

    Taking wasted energy from auto traffic and turning it into electricity sounds hard to believe, but these Israeli researchers may be onto something (h/t LukeHandCool):

    Scientists in Israel say they have invented a way of turning traffic into electricity.

    The bright sparks at the country’s Technion Institute of Technology in Haifa have developed a road that generates power when vehicles pass over it.

    And they hope the technology will reduce our dependence on fossil fuels.

    In a university car park, Haim Abramovich and his team run a heavy truck repeatedly over a special stretch of tarmac….

    It could be used to power traffic lights or street lamps already, but with sufficient progress the technology may one day generate enough electricity to send power to the national grid.

    A company called Innowattech is working with the team to develop the technology.

    It estimates a kilometre of ‘electric road’ could generate enough power for 40 houses.

    Of course, all these Israeli inventions are nothing compared to the advances in technology, medical care, and science which come out of the countries that hate Israel.

    Why all the resistance and ungrounded skepticism regarding this current research? Israeli “juice” could transform the world, were we to amp up support and not re-fuse shocking innovation.

    I say, more power to all of us, or is my reasoning circuitous and me too wired from morning coffee?

    Unfortunately, this is stupid, wasteful and does NOT “reduce our dependence on fossil fuels”. In fact it DOES use fossil fuels–the ones powering the cars. You cannot get free energy from nowhere. It comes from the motor driving the vehicle. Systems like this have been tried before, including one that harvested energy from speed bumps, from cars idling at fast food drive-throughs, etc. They all are incredibly inefficient and harvest barely any energy, and they all have a real cost in gasoline that has to be accounted for. You don’t have to be an expert in the laws of thermodynamics to realize that it would be much more efficient in terms of output and costs to simply hook up a gasoline engine to a generator. Feelgood ideas like this are worse than doing nothing.
