Ricks Pipe Dream

Thread for the project by YT user TheRickoff from the U.S.

The setup consists of a bicycle wheel built into a PVC pipe structure with square Neodymium magnets glued to the rim in groups.

The stator assembly is also made out of PVC and is movable sideways.

Per his request an image explaining my idea of how to time the stator movement using aluminum bars and a stator spring.

Hi AquariuZ,

Thanks for the diagram, now I see what you were suggesting.  First, I'd like to point out that my rotor magnets are rectangular, not square, and that they are not glued to to bike wheel rim.  They are simply held there by attraction due to the fact that the rim is chrome plated steel.

As to your suggestion, I suggest that you build a Pipe Dream apparatus and try it out.  I may be wrong, but I think that any use of rods in such a manner as to knock the stator arm out of the way would not only be very noisy, but would also cause the rotor to slow down and grind to a halt because of that slapping action.  Further, the idea is really not to push the stator arm away to avoid something, but to pivot it slightly so that the south of the stator is used at one end of the magnet group while the north is used at the other end.  Thanks for the try, though.  I appreciate your efforts.

Best regards,

Maybe a cam device?

Or another magnet mounted on a rotor arm above above the wheel that repels a magnet attached to the stator arm? less friction involved?

Nice solution AquariuZ, but I share Rick's view on this.
Even in the bars interact efficiently with the stator, they may not result in the most preffered position of the stator in relation to the rotor magnet groups at all times. The stator is only controlled through a short part of the cycle, it seems? It might work in a fixed RPM setup, when timed perfectly.

If Rick would be able to establish (which I'm sure he's already done) the preferred location of the stator in relation to each degree of rotor movement along one or two magnets groups, a belt/chain drive could be designed to closely match that. Round or even oval cogs connecting rotor and stator. A smooth, silent and efficient operation would be attained.

I believe Rick reported that moving the stator arm in vs. out oer a group goes naturally or requires overcoming over resistance.
By adding a second stator, and connecting it to the former one, or making it part of the the rotor-stator drive/timing mechanism, one stator would be moving in (overcoming resistance) while the other is moving out, the way the stator magnet wants to move by itself. The two might in part or completely cancel out, and net a low energy drain from the rotor in forcing the stators to always be in their optimal position over the passing magnet groups.

If moving the (connecting bar or linkage of the stator of the) magnets takes less energy than is added to the rotor through acceleration, the thing will run on its own.
Even if Rick's hand-assisted rotation was under unity, perhaps having two stator working together might already be closer to achieving this.

At higher rpm, I think the weight on the movin stator assembly will become a greater "jerking" factor, making at least 2x more cycles than the rotor itself.

Depending on the preferred stator movement, I have various ideas to design the timing mechanism, at least conceptually.

Thanks for starting this thread [and others]
Question: I see your design would be good for high torque low rpm

Do you think in magnets, the available power is the strength of the very first attraction and repulsion on the wheel?

Or as in Ricks design [which seems like it will always accelerate ] will its power be limited to this first pull and repulsion ?

Or are we looking at a magnetic turbine using the fields as fuel ?[which might have more potential energy than the first pull/repel]
