Almost Perpetual Motion

a no (wishful, but it's gonna be close) emission motor

My idea for the 2017 Hackaday Prize. It's been a "What If" for a while now, and with the Hackaday prize rolling around, why not make it real? Cars suck (from an enviormental pov, personally i think the whole "global warming is one of the biggest scams in history, but getting off topic) they emit fumes, and there are only so many decomposing dinosaurs to make fuel. Other than that, for the backcountry hillbilly's like me, free (or pretty cheap) energy! Okay, here's the idea, and nobody better make copies. If you put a bunch of bar magnets in a circle, with the same side, let's say north, pointing inward in a circle, they'd repel, right? if you contained it, and put a pole with the outside south, all the magnets would try to attract it, and it would spin. All I want to do is make it spin at first. Stopping, starting, and reversing might come later. Think of a permanent magnet DC motor. I'm not sure, but if you upscaled it, i think you could ma

There are a lot of complicated designs out there for motors using permanent magnets. Search Google for "permanent magnet free motion machine". My idea is relatively simpler, maybe the other designs have plusses or minuses, i dunno. i guess that's part of the learning curve. Some other designs:

My idea is closest to the last one, but the middle is a little different.

there we go, the radial magnets repel, the shaft spins. that's about it. Second thought, the blue one, where is it..

  • 9 × Bar Magnets You can do more, it'd probably be stronger, just put more on the outside

    I ordered my magnets from https://www.xump.com/Science/BarMagnet.cfm, 50 cents is really cheap, and i need a lot of them. I decided to go for the blue one in the details. I was going to drill a hole in the middle of 8 magnets, and bolt them to a piece of plastic in a circle. Cut the middle one in half, it won't affect the polarity. Countersink a hole for the rod, and attach it to the magnet. Hold the rod in place and leave it room to spin. I'm pretty certian it should work, now to research waterwheels..

  • Case, Magnet Configuration

    I would welcome anyone with 3D printing experience who wants to help out with the case. I have one at the local makerspace, but have never used it. Also, I wanted to mention something about the magnet configuration. From what I can see, you can get either bar magnets or ring magnets. There are a lot of different north/south configurations, but only two that i can see as helpful for this.

    Radial:

    Diametric:

    (Sorry, couldn't find a bar magnet diagram)

    I'm going for #2, Just put the other ones on there because

    Configurations:

    -Bars around Bars (arrange the bars in a ring in the center, a ring on the outside

    -Pros: Bars are REALLY easy to find

    -Cons: Keeping a structure on that would be like REALLY hard

    -Bars around Radial

    -Pros: Bars are easy to find, somewhat easy to setup

    -Cons: Bars need to be held together, Radial hard to find

    -Radial inside radial

    -Pros: Simple, Clean

    -Cons: Radial magnets are hard to find, custom orders take a while

    It's impossible to make a perpetual motion machine with magnets because magnets go bad. A magnet is made of iron, and in the iron the atoms are "relaxed". Don't ask me how, but to make a magnet, you need to "charge" the particles. Eventually, the particles relax again, and the magnet dies. How long depends on the type of magnet and the usage. So, in conclusion, unless you could get enough power to control a "magnet charger" after 100 years or so, you can't do it. you can, however, make a really long lasting motor.

umm, a lot i guess, it depends on the magnets. i read somewhere they should last for 75 years or so

  Are you sure? yes | no

I'm not sure it is a lot in a normal magnet, because when you use a magnet, generally you apply just as much energy as it gave to remove it. But i doubt many magnets are made to the highest potential power. I think the longevity isn't related to capacity, but it is a great testament to the long term power storage potential.

So looking at the top image in your project details, the motion produces energy while the magnets, demagnetise. So in actual fact it is a magnetism based battery?

  Are you sure? yes | no

ah, i didn't think of it that way, yeah definitely. that's really cool!

Whats the potential energy density of magnetism?
