Work from 2 magnets > 19% output 2

How much energy is required to turn magnet 3 in that video?
If both magnets are rectangular, they would  be hard to turn 90 degrees of each other.
I know about the slide-force-part, and that require less force to do, but what about the displacement needed to slide them apart?
Would the displacement needed for sliding be 4 times the displacement needed to pull the magnets directly apart?

I'm sure it depends on the shape of the magnets but you can bet it's not the 25% as he is claiming.
From his sketches I would think it would be closer to 80-90%.

With all the moving parts in that design I'm sure any gain would be quickly lost to friction.

Thanks, I'm thinking on /  looking for some simple design, but pretty much stumped / busy at  present.

@ Lumen and Low-Q

I also think the mechanical linkage design, in the Jessie R. Johnson video would be a very ineffective one,

But also I think the sketch was probably just intended to illustrate the idea of / necessity of... mechanical
linkage and timing of RO and SL in order to get cyclic operation.

I'm thinking more along the line of the Steorn nodding donkey!
Is it possible that they really did have something and couldn't release it because it wasn't theirs?

I'm setting up now to do some actual measurements on real magnets both to see how close the results match the simulator and to collect some real data before building anything.

@gotoluc

Lumens nodding donkey idea sounds to me like a good starting place
for a simple desigh ?

@Low-Q
Are you looking into electro magnet design variations ?  see the design

My test measurements on the real magnets produced a gain of only 12%.
That is about half of what the simulation suggested and is what I consider to be within error limits where there may actually be no gain at all.

My scale was not accurate enough to detect the weaker forces of the small magnets with a resolution of only 10 grams and so may possibly account for some error.
The good news is that it does indicate a possible gain.
