    At Cop 15 a company named Hidro displayed sustainablepowerstation.com ,,they were only ones allowed, so we thought it had some merit but not sure?. Principle is that the amount of energy used to put a little air into a tank is less than the amount of floatation work that air tank lifts to the surface? Then on the way back down the air is first released and gravity does some work to go down. I believe it does not take as much energy to float the tank as the float ride up gives out? Maybe someone knows more. I know the rule is energy in equals energy out, but maybe there is an exception ? gravity ? floatation ?

    It's purely a scam. I visited their website: http://sustainablepowerstation.com/

    And noticed they were VERY careful to not mention any figures for power requirements OR any claims of power output.

    Sure, the gadget could produce a minuscule amount of electricity, BUT there are power conversion and friction losses in any system. And once you factor those in, plus the fact that it takes as much energy to displace the water (more, actually) than could be recovered by the buoyancy, you'll quickly see the whole thing is nothing but an energy drain. (Negative gain.)

    Agreed. They are purely out for the dough.
