(yes, I'm sure pages ago this was all mentioned but I just got here)


I can definitely see that as a viable gravity engine...  but it's lots of torque and not a lot of horsepower... kind of like a huge flywheel... or a static resonant tank... sure you can get get KW cycling, but if you try and pull from it, you kill the whole thing and have to start it spinning again....


but with a small continuous input, and NOT taking the whole energy... like only take a portion of the energy ... should be able to run some numbers.... I'd try and build it in space engineers but they don't have pivoting joints, only linear... and there's lots of CV or universal joints that can be used...


And sure it's low speed, but so are wind generators...

So I've been considering this.  The only way something can fall is if it is higher than it started....
from equilibrium/stop condition, the first motion at the top actually raises the weight slightly.
gravity acts not on an entire body... but is really about the center of mass....

*thinks* ... need some better sketches and models...

Edit:
I'll have to dig way back into memory and pull out some calculus I guess...
as the top moves (rotates is the simpler model), X degrees, then the center of mass is lifted, and then falls at an angle and creates a rotation as it falls back to its original height.   This path is always longer than the height it was raised, so it must take a longer time, therefore it's accelerated by gravity for a longer amount of time than the time which it took to raise the weight in the first place.


if the angle at the top of the shaft is very slight, then less work is applied to raise the weight, though it then has a much shorter distance to fall... but the angle of incline should resemble something like a cylinder rolling down a hill accelerated by gravity.  So it's forward motion will be sin(slope) * m * g...   But; that would only work if slope < 90 degrees... if it's vertical m has no bearing.... so then is it really a cylinder on a slope?  (feather and hammer drop on moon).

(distraction; not applicable: hmm a long chain falling out of a beaker goes up first... like way up over the beaker

)


Hmm... well due to inertia, the mass falling vertically must have the same force being applied if it's non vertical, and something like the cos(angle) vertically and sin(angle) around axis or rotation... but then to get to the bottom it must apply that force for a longer time than it took to raise the object in the first place, resulting in a net acceleration of the object greater than the initial impulse....


search for "gravity acceleration tilted axis -accelerometer -digital -sensor" didn't reveal any useful math... so maybe again it's a case I don't know what physicists would call it?


or 'acceleration deflection gravity around tilted axis -accelerometer -sensor'

Hmm; I didn't notice the first time that the drive on original Skinner was linear.
I guess as the eccentricity of the drive ellipse flattens, you require more work to raise the weight to a higher level, but you get a longer cycle where the weight's falling is... going to be ahead of the drive.  that may be an interesting path to a solution of acceleration.

Picture; Red is highest force applied to lift weight, pink is lower force, but still requires power, light blue is 0 to slight gain in drive, dark blue is positive feedback on the drive, where the forward acceleration will outrun the drive.

Looks like a sum of equal parts to me... or a continuous loss... Well it will be a lot of light pink and light blue segements so it will balance to zero... the first slight impulse will require power, but the weight will outrun the drive quickly being slightly blue, which in turn will slow, and the drive will catch up slightly and apply more force....

i just wanted to write something like that

the easy way to emagine john device is to emagine a huge weight that is rotating on a nail
starting easy,and picking up speed it would seem like the output is huge .like he claims,
but in reality he never counected output becouse it would only stop the device.

Hi All,
The conduct energy efficiency measurement, test on a small unit of the machine Skinner did not reach the expected results may be due to:
- The weight of the mass (rotating) is not large enough.
- The velocity of the mass (rotating) the kinetic energy generated is not high.
- Mechanical friction of the rotating parts is too much.
- Convert mechanical energy into electrical energy to achieve low performance. . .
