  • Linear alternator fun

    Sorry, my cut & paste option screwed the first post up beyond all recognition. I Did the original post again in the reply to this. Start there and I look forward to hearing your thoughts on this theory.

    I'm interested in working with linear alternators because they seem well suited to DIY devices and might operate more effectively from lower input energies, including vibrations. Of course, I want to take my shot at overunity, so here I am.

    This idea stems from James Roney's research/YouTube videos on magnetic shielding and from the Ecklin Generator, which is supposed to bypass Lenz's Law.

    Consider this a completely open source project, if it eventually proves viable. If you are interested, please try it out and report back.

    Here's the setup I have in mind. Wrap a coil around a plastic or PVC pipe. Put cylinder magnets (Neos) inside the pipe, each one in opposition (repulsion) to the others.

    Next, put two stationary (neo) magnets, one at each end of the coil/pipe, a couple of inches away from the pipe/coil. Each of those two stationary magnets should be in opposition to the closest magnet inside the coil on that end.

    At this point, the magnets inside the coil are being pushed equally on each side by the stationary magnets just outside each end of the cool. The magnets inside should equalize, or settle, between the stationary magnets.

    Next, set up two discs on an axel below the coil. Discs should be plexiglass or plastic---something nonmetallic. On those discs should be 4 "shields" or inductors. These are made of layers of ferrous metal, like iron. The inductors of each disc should be staggered, so they are never in the same position at the same time. The discs go between the stationary magnet and the coil at each end of the coil.

    When the axel turns, the discs rotate. The "shields" on each disc rotate between the stationary magnet and the coil/coil magnets. Since the shields are staggered, they can arrive at either the right or left side of the coil, but never both at the same time.

    The shields should momentarily disrupt the repulsion between the stationary magnet and magnets inside the coil on one side at a time only. This should cause the magnets inside the coil to oscillate from side to side as each side is momentarily shielded. That oscillation should be seen by the coil as movement of the magnetic fields inside the coil, generating electricity.

    Since the discs with the shields are not subject to repulsion against rotation, their operation (spinning) should not be subject to Lenz's Law. The force of attraction will be a force against rotation, along with friction, but not repulsion from the coil. So, the ratio of input energy vs output energy should be different from a standard rotary generator that is subject to Lenz's Law.

    So, there it is. I have a ton of questions about this setup, and so should you. Will the output electricity be more than the energy required to spin the discs/shields? Will all those neo magnets in opposition to one another be demagnetized from oscillating like that? Will there be heat issues that demagnetize the magnets? Can this setup generate a usable amount of electricity? Will adding iron filings between each layer of the coil increase the flux from the inner, oscillating magnets? Will using laminated shields reduce heat from eddy currents?

    I don't know and neither will anyone else unless we try it out. I put a cylinder magnet inside a short piece of clear pipe, set a stationary magnet in opposition at each end of the pipe, then swept a piece of ferrous metal between the stationary magnet and the pipe's end. The inner magnet moved each time I did this, so I'm pretty sure those magnets inside the coil will oscillate in the setup I just described. I don't know how much energy I used to pass the shields between the stationary magnet and the magnet inside the coil, but it didn't feel like as much as bringing two magnets in opposition together.

    That's all I've got for now. At this point, this is only a theory, but I think it's worth trying. I've never seen this attempted before so I'm not sure what to expect. By all means, try it out and report back. I don't care who gets credit for what, so long as it remains open source and spreads if viable.

    Nice place you all have here, BTW. Glad to be your newest member.

      Mangyhyena Welcome

      Your proposed idea is intriguing we will ponder on this for a bit . . . it sounds like you have started a few initial experiments with your concept – congratulations and to this list.
      Perhaps you could share some pictures of your work so far.

        Hi Mangyhyena,

        I have made a simple drawing on your proposed setup as per your description, albeit I used a single disk to support the shielding plates just for simplicity but I understand your dual disk rotating at the ends of the pipe on a common axle.
        I did not draw the output coil onto the pipe.

        Does this drawing cover your idea?
