Gravity Motor Patent 7/10/08

[TinselKoala]

TinselKoala's (evil skeptic) Mondrasek rotor, with non-magnetic bearings (sapphire balls, plastic races).
It's a 12-holer, but I only had enough magnets for 6 holes. They slide fine both with gravity alone and with "firing" stator. The little slot halfway in is for the latch magnets (so far this idea seems to work too, if you have tiny magnets for the latches). The retainer screws are plastic, #4-40.
I used Acrylic instead of Delrin because, well, I didn't have a big enough piece of Delrin scrap.
Plus the clear plastic lets one see where the magnets are and what they are doing.
This represents about 4 1/2 hours work (I don't use CNC, it's all by hand) and about a quart of WD-40.

Tomorrow I'll mount it on a vertical stand and make the stator mounts.

Very nice work Tinsel.
I hope all the hard work goes towards curbing your skepticism

Just a quick note on Clanzers brass rods.

Ever drop a magnet down a copper tube? http://www.youtube.com/watch?v=pcVG6c_OvYU&feature=related

Or even slide in in an aluminum track?

Using highly conductive materials (yes even salt water) around magnets, will impede movement due to the eddy currents.

Lenz's Law applies.

I don't want to sound like a broken record but Harvey is absolutely correct. Experimenters need to source
non metal, non conductive, materials for use directly inside magnetic fields. Think, carbon composite, fiber glass,
lucite, plastic pipe and engineered stone material for weights. If you don't do this then one experiment does not
immediately let you conclude the success of the next. Note that Lenz braking will be proportional to mass.
In the final version after you sure you've optimized everything then you can try adding in metal. You may be able to
use your device as a space heater who knows? Just Kidding. Remember when Archer said his machine became more
powerful...when he removed his magnet arrays. Also Steel and ferrous metals will magnetize over time changing
magnetic parameters...*if* permanent magnets erase themselves try an aluminum buffer sheet again ala Archer. It
may be that magnetic domains move because of brownian molecular hits causing permanent mag fields to be
slightly more noisy than electrodynamic fields and aluminum may filter and smooth this out.

Thanks, shakman. But there's only one thing (or set of things) that will curb my skepticism, and that's building one that works. Or seeing someone else do it.
I build them myself, generally because nobody will believe me when I tell them their ideas won't work. So I try to get around the objections of improper materials, inaccurate builds, and overenthusiastic designers who only see what they want to see, by building one myself to the designer's specifications or with obvious improvements or buildability mods. Unfortunately, even when these things are done correctly, the devices still won't work...
Except for one time, when this technique backfired on me...but that's another story altogether.

So with my mondrasek rotor, I know it's a bit small and the magnet/weights don't travel very far. But the wheel itself is well-balanced and the bearings are pretty good, and it only takes a miniscule out-of-balance to make the wheel rotate. Even if only one single magnet is out while all the rest are in, the weight shift is enough to overcome friction and rotate the wheel until the heavy spot is down. The magnets slide nicely in the channels from gravity alone at about 30 degrees from horizontal--so if the magnet is near the hub (top magnets) when the wheel rotates so that the channel is about 30 degrees below horizontal, themagnet will slide to the outside under its own weight. Ditto the other side--if the magnet is at the outer rim, as the channel comes up past about 30 degrees above horizontal, the magnet slides under its own weight to the inside stop.
I expected greater angles would be needed--I guess I got the inside of the magnet tubes sufficiently smmootthh enough.
Tomorrow the running mount and the stators.

Interesting design do you have a working unit that you could put up on youtube in action?

I think its logical but how does your heavyside remain heavy do the magnets slip past the little wisbone switch you have made once they reach a certain part on the wheel I guess functionality is kinda a question here how does this wheel function ?
