Waterfall Turbine/Magnetic Feild Inducer

  1. Nov 7, 2006 #1

    The link above, and the attached file are simple diagrams of what I plan to do.

    1)Magnetic Reservoir
    4)Metal Ring (non Iron)
    5)Magnetic Reservoir 2

    First let me explain what the magnetic reservoir is. A large amount of a high power permanent magnet (neodymium for example) will be ground down into as fine of a powder as possible. The powder will then be added to the two reservoirs.

    The damn will then be opened at the top, causing the water from the top to flow through the dam and move the turbine (The spinning turbine will create power for a load, EX: a light).

    Then the water will pass through the loop, the loop will create a current, which will be sent to the pump.

    The pump will then pump the water, which magnet dust, through the hose and back to the first reservoir. The water falling into the two reservoirs will cause the magnets to be stirred about and not clog the pump/dam.

    The process can also be switched so that the magnets power a small light, and the turbine is able to power a pump.

    Any input?

    The turbine will not produce enough power to drive the pump. You must understand that the amount of energy taken from the turbine depends on the height of the water, so to optomize the turbine, it needs to be all the way at the bottom of the system. At the same time, to get the most out of the loop, you need the water to be falling as fast as possible, so it also needs to be at the bottom of the system. You can move the two up and down 'till your heart's content, trading energy back and forth between them, but the total energy provided by the combination of the two, ignoring efficiency losses, will always be the same and will always equal the potential energy of the top reservoir. Toss in some efficiency losses, and you'll never get what you need to drive the pump.

    "Lisa, in this house we obey the laws of thermodynamics!"

    People have been trying to build perpetual motion water wheels for a milenia and they always fail. I recommend you stop wasting your time with it and learn some thermodynamics instead. Either way, we'll help you understand why it won't work, but we won't entertain crackpottery here - so be aware that this thread will have a short leash.

    What will prevent the magnetic poweder from attracting to itself?

    Well a group of us was working on this in my class, and amazingly no one realized that the powder would just stick to itself as the above post said.
