Gravity Motor Patent 7/10/08

[TinselKoala]

I am very happy to announce that I have successfully tuned the upper stator arrangement in my embodiment of the Mondrasek Magnet-Assisted Gravity Wheel. It turns out that a little "centrifugal force" is needed, since the attraction to the wire must be so light. I don't have time this morning to demonstrate it by video, but if anybody is still building, this idea works fine as intended, and is simpler and more efficient than mechanical latches would be. The best part is that it does not add perceptibly to any "wall" or energy hill. I have not had time to do rundown tests, but so far--no go, Even with the apparent imbalance caused when the latches function as intended, the wheel still will not turn of itself, and we know the reasons why.
Just looking at it, it is hard to see how there could not be several gram-centimeters of torque generated by the off-center magnet arrangement produced as the stators fire. Spin the wheel by hand, stop it to see the magnets and all the magnets on the right are out, all on the left are in, as they should be when clockwise turning. It is fascinating to see.
I almost believe it would run, myself.

We want video !

Good work with the retuning. Also looking forward to the vids.

Please read this. It is a constructive and possibly important post, unlike some of the little digs we've had at eachother over at the Archer Quinn thread. I think this could be the key to getting a wheel like this to work and the main reason why things like the Besseler wheel don't work. I know these don't use magnets, but it all has to do with the position mean centre ('center' for my friends in the USA) of the magnets as opposed to the wheel axel.

Has anyone tried out my idea of firing the bottom stator earlier (say, at 4.30 or 5 o'clock, maybe even earlier)?

The way I see it, by firing directly up at 6 you are creating more negative torque than neccessary and fighting gravity more than at any other angle.

But, more importantly, the natural movement of the magnets with gravity when firing at 6 also puts the centre of the weight of the magnets to the bottom right of the axel (on a clockwise spinning wheel) which is definitely not ideal. You want the push to come from the top of the wheel. Also the shape of the mags that is being created by firing at 6 and 12 keeps the weight fairly well centred across the horizontal in general by pushing out a shape resembling "cD", where "c" is the small circle created by the rising side of mags affected by gravity and "D" is the falling side. Notice the symmetry? You really want to throw this thing off-centre as much as possible while keeping the mean centre of magnet formation to the upper falling side of the axel.

I really believe this wheel will never work when firing at 6 & 12 as originally planned in the patent, it is too balanced across the horizontal.

@Clanzer - Any chance you could try this too?

I will be testing out these ideas myself shortly. I will buy some magnets and materials on the weekend, I'm getting a little impatient waiting for my package from the US!

BTW If this does by some crazy chance work by using my "early firing" idea and this contribution makes the patent null, I will personally send a donation to Mondrasek but I declare this info public property. If it works but doesn't make the patent null, I urge Mondrasek to be careful with whom he deals.

I can't believe I am gonna go here, but...  Halbach Arrays.  If you force 5 square magnets together in the proper orientations in a Halbach Array you move most of the magnetic field to one of the long sides.  That side now has a North and South pole of nearly double the strength centered around the second and fourth magnet.  But what happens to the wall if approached from the side?  I believe it would be pulled closer to the edge of the array, but then be proportionally stronger, requiring just the same amount of energy to traverse as that of a regular magnet of equal strength.  Like the magnetic field lines have been squeezed on the sides.  Is this correct?  Anyone know of a diagram that shows the field lines on a Halbach Array through sections cut in each of the 5 magnets?

@Shakman,

Are you wanting to fire the magnets early (before 6 and 12) due to the time it takes them to travel to the other end of the switch tubes?  So, in effect, they fire early (advanced), but make it to the other end exactly at 6 and 12, or at and equally late time (retarded)?

I like this idea.  For example, if you fire the bottom switch at 5:45 and the magnet arrives at the other end at 6:15 at the optimized RPM.  Am I following you correctly?
