So it goes with hydro enthusiasts. Motivated not so much by money as by the chance to continue playing in that ditch other boys forget when they grow up, they achieve a sort of immortality. Since a turbine's useful life is 50 years or more, wheels stamped HARRIS and NEW and CUNNINGHAM will still be spinning long after their makers are dead, transforming falling water into eternal delight.

    Vincent,
    What you are proposing is a perpetual motion machine, something that produces more energy than it uses. Or let me put it this way, in a perfect world with no mechanical or electrical losses, the amount of electricty that could be produced by 1 gallon of water falling 10 feet (say) is just enough to repump that 1 gallon back up 10 ft. In the real world, the 1 gallon falling 10 feet would produce enough electricity to pump the 1 gallon back up about 7 feet.
    Cheers
    Bob

    Hi i know this is an old article but ill see what happens. I'm just
    wondering whether a closed circuit with an electric pump that
    produces flowing water around a pipe system with a number of
    generators in it then back to the pump to start all over again
    would produce enough electricity so that both the pump could be
    powered by it and also there be an excess of electricity that could
    be stored in a battery for home use? Not being a physics student I
    have no idea how to crunch the numbers. If you can be of any help
    that would be much obliged, if not thanks anyway.
