    Yeah, bs on the free energy from car tires and pedestrians, and more bs on the ever-so-soon cold fusion plants. Either it's a total hoax that just likes the attention, or they're sniffing for investor money (YOU could get in on the ground floor of a NEW technology that will CHANGE the world.) and it's a hoax of criminal proportions.

    Thread Segue... Cold Fusion... again

    The science news story I am keeping an eye on is the latest in cold fusion (or whatever they think it is). <http://phys.org/news/2013-11-italian-company-portable-cold-fusion.html#ajTabs> has a story about an Italian company (ECAT) building cold fusion plants for sale early next year. The website phys.org seems like a reasonably good science mag type site, otherwise I would have shrugged it off as B.S..

    Hi
    "Wind generators slow Earths rotation....
    Wave action restriction can also affect the planets rotation..but in a small way"
    Surely the wind action is generated from solar energy and the wave action is from the moon and the earth hurtling through space massive residual energy from the "Big Bang"
    No such thing as a "Free Lunch".
    All we have had is theory based on personal opinion. It seems that we still have sellers of the new "Scientific Snake Oil" to grab money for their own ends.

    IIRC it was a supermarket that had a system installed where cars drove over it into the car park,the electrical energy generated powered all the checkout tills.

    Most of these people were the ones that received a "failure" grade in Physics class
    Energy can not be created, only transformed...... they never learned that !
    You can't take from one without affecting the other

    So they try to "save the planet" and have zero thoughts on the above
    Wind generators slow Earths rotation....
    Wave action restriction can also affect the planets rotation..but in a small way

    The posters original comments about the Mexican approach is right on ...why not make all sidewalks the same way ?
    then walkers would generate power by going up a set of stairs.

    I remember that. It was in an article in Pop Mechanics or Mechanics Illustrated. I liked the idea of capturing tidal water at high tide and then letting it out at low tide through a water turbine/generator. But both of them would be fantastically expensive to build and maintain in relation to the energy that they would generate. Just not practical.

    Yea, but how does the driver control it? The devil is in the details.

    D'yeh think that's what they meant? Not from what I read.

    And less brake wear? maybe, traded for suspension and tire wear.

    In Illinois the roads are so rough know one would notice little ramps in the pavement to generate power.

    Here in DeKalb County we must have over 100 wind turbines. Opinions are mixed on the value of wind energy. We never hear if the wind turbines are making money or not. I see huge wind turbine blades being trucked down I-80 so they are still building wind turbines. I have a hunch someone is quietly getting rich off those turbines.

    I have to ask, what would be the time frame for a return on investment for such a left handed way of obtaining this "free" energy?
    The associated maintenance costs alone would be staggering for the energy recouped never mind the initial infrastructure costs.
    May as well put little propellers on the side of the road in order to catch the wind from passing traffic and convert it into even more "free" energy.

    hah, not if your a Prius driver,,, you would be cursing them for the lack of battery charge and the more money at the pump...

    As for extracting the energy while braking, that has been done, but in the vehicles, not in the road. It seems to be a lot more practical and probably more efficient that way. I mean, how would you transmit that energy to the road?
