My guess on how it should work.

With the correct measurements and what not that might work.

Seems like only half the possibility is there. Why not extend the offset shaft on the wheel to the other side of the wheel and have an identical lever arm and magnet assembly on the other side. Having double the push energy from dual magnets you could then increase the 'flywheel' weight which should increase the power without having to add another wheel.

Okay.. brain far* there. Of course if you extend the arm to the other side it would hit the support for the wheel hub. Duhh. You can get around this by having the wheel turned and supported by the rim and not the hub. I will have to see if Sean have any luck before I try..

I will be curious to see how the trigate work with it.

@Omega_0

 I looked at your animation and it seems to me using two magnets that attract may be a little tough on the return.

@hydrocontrol
Connecting many cranks on a single axle is possible, but I wanted to keep it simple and stupid. Its only a 3D model after all :)

@AB Hammer
Do you mean in the original machine, there is only one magnet and the other piece is iron or something?

Here's a very tedious paint modification that is inspried by other ideas...

(http://broli.dommel.be/gravmag.PNG)

But this shows a way to weaken the magents attraction when the weight is going down. I have to point out I have little knowledge of the effects of shielding and what not though. And also I think it could be more powerful if the magnets are in repel mode. The shield would weaken the repulsion enough so that the weight can make its swing more easily. All theory untill proven working :p.

Edit I was thinking. As the shield is passing by the magnets BOTH are  interacting with it so the net force is ZERO by the magnets. Meaning you get the shielding for free. Please tell me I'm correct  ;D.

broli, good thinking on the shield , but perhaps its too big as shown here and will disrupt the wheel's balance. It may not spin at all with this much load.
Now I'm thinking the earlier design was a bit rigid. It must have the wobble.

Hi Tinu,
Thank you for your colorful post. I couldn't help but include the truth about the girlfriend. I just wish I had gotten coverage of her when she came in that night, drunk with angry behavior, as though jealous of a goofy, awkward gizmo that drew my attention away from her. Please feel welcome back to the site. The video was edited "in camera" (at the time, I felt all else was redundant) Technically the only thing that would change over the time frame that it would "mimic" initial "start-up" rpm was actual rpm would apparently, gradually, slow over a 12 hour period....then would gradually pick back up throughout the next 12 hours to a peak....& repeat.

kind regards, Ronnie

Interesting video, no doubt about that. Thanks for posting. But it?s too interesting imho. I can see a similar scenario like the past ones: short movie; made n years ago; don?t know what happened meanwhile; everything else (much more relevant) is lost; I?m too stupid to see it?s something that could change the world if real; emphasis on something different (this time his girlfriend); good video editing despite short duration but still giving enough clues for ?replicators?; perplexing simplicity; highly motivational, not at all scientifically/technically; easy to fake; dubious user profile.

The mechanism reminds me of an old sewing machine (pedal powering a flywheel; ?Singer? trademark) my grandmother had from her mother, long before electricity was introduced to masses. It was still functional when I was a child and I was always fascinated at that age by building momentum into that flywheel.

Now, I know that gravitational motors can not possibly work. (Some will disagree but they have their opinions and I have mine.) I also know that magnetic motors can not possibly work. Same bracket applies. Why shall I buy a clumsy story about a gravi-magnetic motor, as long as it is also known that gravity and magnetism are independent forces? I?m sure plenty will buy the story, anyway. Just felt like posting for the ones decided to rip apart their bicycle as of tonight then regretting tomorrow.

Time will tell.

Cheers,
Tinu

Hi, My name is Ronnie...... (itsblockdog)   the gravity/mag/wheel/device is on youtube. Please forgive me if this communication appears intrusive. I humbly hope to extend my hand in friendship. (I must not presume deeper readings within posted conversation but, "a bit rigid" YES. Of my experience to "it" ..... IT demanded for the "wobble" in effect of the "orbit" IT would travel. The "wobble" was the physical action, point of exchange, (in polarities) as the magnetic fields switched from attraction to repelling. The "orbit" was one like that of a comet.(These are only statements in regard to what I eveluate, limited to my own reasoning.)  I hope to make your aquaintence.

Kind regards, Ronnie

Just an idea...on how to implement this wheel.
 

@Omega

Fantastic Graphics mate, well done for the time and effort, excellent job.

Cheers

Sean.

Hi Gwhy!

Good graphics mate, well done.

Sorry to say the Tri-Gate lacks one thing and that is Torque, Okay you can added stronger magnets etc, but you then increase the size of wheel etc etc to match.

But good idea as I know exactly where you were coming from apart from you would have to rotate the middle magnet before the roller could do the down stroke.



Hi Sean,
I had a very quick play with this setup when the link was first posted very intresting but more to the point it did start me thinking again about tri-gate arrays and what if's. The rod end takes a elliptical motion so why not fix a roller mag on the end of the rod then have 2 fixed sets arrays at the bottom either side of the roller mag pushing the rod up on one side then pulling down on the other then then lay the whole thing flat so it will not have to fight gravity. It is something I do intend to have a play with. I hope you know what I am trying to say.    If not and your intrested let me know and i will try a draw it for you.

edit: managed to draw something up quick to try and show what I mean.

Got to agree here, cool idea Broli and can see a simple steel shield being usefull on the upward stroke to alow release.
ummm got me thinking now.

Hi Alan,
I hope this communication does not appear intrusive. I'm stumbling my way through here and found you. Thank you again for your kindness. I'm trying to get sav vy to this site..... (I'm a "newbie?")    All the best to you and yours.
Kind regards, Ronnie

Welcome to the forums Ronnie

Well you have got our attention and this weekend I will be trying a Bike Wheel. As the Missus pointed out the other day, the kids bikes are in the shed and they never use them, so will pinch a wheel or two LOL!

Have you not tried to build this since Ronnie?

Cheers

Sean.
