another way to fight lorentz

[DreamThinkBuild]

@Gravityblock,

Thanks, that is some good information about the voltage decreasing outward from the center (bloch wall) and at the junction between stationary magnet and moving magnet I came up with this interpretation.

In this design the large magnet is only there to keep the smaller magnets in orbit. Instead of riding directly on the stationary magnet have a thin copper ring which is insulated from the center magnet which the smaller magnets ride on. If the bloch wall is where the highest voltage is then maybe a smaller cross section copper ring could be used. Thinner, the better to reduce eddy current losses.

Your free to modify the picture if you see any other ways.

I'm waiting for the ring magnets to arrive, so I can start testing some ideas.

I order 1 of these as the center magnet:

and some of these for the orbiting magnets:

It's my first post here, so hello to everyone

Ok guys, now some of my thoughts. Why a hell do you want to use a homopolar generator in your original project mr_bojangles ?? First of all there is no lenz drag in homopolar generators just as they are (if there is please tell me where ?), so why to invent a wheel again. There is no sense in it. The problem with homopolar generators is their huge current and low voltage generated. How do you want to utilize a huge current ? Another problem with them are brushes friction and big RPMs needed to make it work. All in all that's why people don't use homopolar generators nowadays (at least I don't really imagine where they would be needed) ;]

That's why you need to use classic coils (I liked a schematic with horseshoe magnets or a halbach array idea).

Another problem with Next generations of your original project are the machanisms making the discs stay upright. Any mechanism which is connected in anyway with the axis of rotation of the main wheel will ruin everything. Note, that in such a connection a lenz drag from the discs will be transfered to the main axis and slow it down as in classic generator. So all in all the best configuration for now is with the coat hanger wire. But hopefully there is something better By the way, I'm also wondering... maybe there is a configuration in which the lenz drag could be used to to make the main wheel go faster ;> That way we would not only cancel the lenz drag but also utilize it ;>

Personally I really like the idea of Mr. Th3Generat0r. I think this can really be able to selfsustain if the rotary speed of the big wheel is big enough (able to keep the ring magnets rotate all way round - which is needed to fully cancel any drag). His frictionless prototype is also really nice.

Also I'm thinking of another setup - pistonlike. But need to think of it a couple of days more.

If I'm wrong at any point just let me know - it's better to know that you are wrong than leave in a dream ;]

welcome and greetings

well to be honest the original design wasn't supposed to be an HPG, but its pretty irrelevant

andd to start off, there is a lot of lenz drag on every generator, including HPG's and all other types

lenz drag is induced into whatever mechanism you have that rotates the disc, in a normal set up, its usually a crank or motor, whatever

because the magnet is stationary, it can't give into the lenz force, so all of it is projected into the disc itself

the disc gains its own magnetic field, and opposes turning in the field of the actual magnet

the faster you spin it the harder it becomes to spin essentially

and currently there are no proven methods of using this drag in a beneficial way because no matter which way you push spin or rotate it, the force is always the exact opposite direction


this is the problem with all generators, but the real reason its an issue is because this opposing drag is essentially what is generating electricity in the first place

my original design used couterweights so this force would fight gravity, the problem is most definately in figuring out a way to keep them upright because centripetal force would make the counterweight ineffective at high RPM's

ive never messed with pistons, although i have been wondering about a way to apply this idea to hydraulics


appreciate the words of encouragement

ok please have a look at this document:
http://www.physics.umd.edu/lecdem/outreach/QOTW/arch11/q218unipolar.pdf

In this special case I don't really see any lenz drag - so if in this special case of homopolar generator there is no lenz drag why to build anything different that uses the same principle? This will simple not be OU and hard to utilize as said before.

[mr_bojangles]

lenz drag will be induced into the rotating magnet,
in the exact opposite way that the magnet spins

electricity can only be generated from movement, and whatever you spin will end up receiving the majority of lenz drag

if there was a proven method of doing this it would basically be OU by itself, that's why i find it hard to believe someone has figured it out already, especially using just an HPG, and it is what my own mechanism is designed for, a way to generate electricity without having to account for this
