Buoyant Piston PMM

[WeedJay]

Wanted to run this new idea I got for a prototype. I'm going to try and explain my hypothesis and link to a gif animation diagram I made as a visual.

The three main forces I will be combining here are:

1. Magnetism (in repelling setup)
2. Gravity
3. Buoyancy

Hypothesis:
We can achieve unity and possibly over unity by using strong N52 disc Magnets attached to each side of a cylindrical piece of foam float held inside a single cylinder filled with water (example 4 inch pvc pipe that is 6 foot long with end caps tight water filled with a foam core piston free floating inside the pvc and 2 large disc magnets fixed to the top and bottom of the foam float with the same north magnetic field pointing out of the PVC end caps).  On the outer perimeter of the cylinders circular path a spiral of magnets face north inward toward the cylinder and are fixed above the horizon of the cylinders path covering from 3:30 on a clocks face following a path counter clock wise past 12 o’clock to 8:45 (magnets placed so the spiral at 3:30 is closer to the cylinders circular path than the magnet placed at the 8:45 position) The rotor cylinder is held at the middle by an externally mounted axel allowing the tube to spin end over end from its center inside the outer magnet spiral. Once the internal piston floats to the top of the tube the magnets on the top of the float create repelling force against the spiral fixed magnet setup around the outside of the rotor (as they come into range of each other).  The outer spiral setup of the fixed magnets directs the top of the rotor cylinder around through the path of least magnetic resistance from the 3:30 position to the 8:45 position.  Once the cylinder is forced passed the 9 o-clock position gravity takes over dropping what was the top of the cylinder to the bottom forcing the foam float with magnets attached to restart its upward path again to run through the magnetic spiral path above.

The sticky spot that we see in the typical minato wheel  rotor setup people have attempted to make in the past have a  "sticky spot" where the internal rotor reverses direction after passing the outer magnet spiral gap, making the rotor fail...

The design I'm proposing does two things to remove this sticky spot.

1. The setup must be vertical and the rotor cylinder must spin end over end allowing gravity to be used to its full advantage.

2. The actual path of the rotor's magnets must physically make a path that avoids the protrusion of the magnetic field at the beginning of the out spiral so the sticky spot isn't in the path to begin with.  In my animation you can see a better visual of how the internal float piston travels inside the tube as the cylinder is slowed by gravity and the force of the upward buoyant movement of the internal float, pausing the circular travel of the main rotor cylinder momentarily as the internal float piston makes its travel back up to the outer magnetic field spiral, restarting motion (the rotor slows as the float avoids the sticky spot instead of reversing directional spin).

To calculate the exact piece of foam float I would need to cut, I would refer to the Archimedes Principle: "When a solid body is partially or completely immersed in water, the apparent loss in weight will be equal to the weight of the displaced liquid."

Formula for Density of immersed object relative to the density of the fluid object is immersed in:

Relative Density = Weight / (Weight - Apparent Immersed Weight)

From the Archimedes principle I should be able to calculate the correct size cylinder to cut the foam float in order to create enough buoyancy to push the weight of both magnets and the extra force to repel the cylinder rotor with the outer magnet spiral. The resulting piece of foam float material to be used after making that calculation would definitely be large enough to distance the two internal disc magnets attached at the both ends so that their magnetic fields do not touch.

Feel free to respond, I would like to know what you think…

A very ingenious setup!

I don't fully comprehend all dynamics yet, but fear there will either be an equilibrium position found, or even a reversal of movement. My gut feeling tells me at 9 o'clock, the picton will not travel inward quickly enough to allow continuation of the counterclockwise rotation. Until I find a specific reason why this won't work, it surely deserves further study, and building can't hurt.
Good luck!!

scrapping this idea...... won't work.
