Why this seesaw is working against physics laws

I get what you are saying, and can see/feel the momentum
But won't this be absorbed by compressing the spring?


falling ball compresses spring, spring pushes the ball back up


our 25 J is (partially) returned to us when it resets
But we have to put 25 J more do go another cycle.
So we lose part of the 25 J each time.


Like in your video, when you use your hand to lift it up.

It is a very strange way to transfer gravitational potential into momentum


But in experiments I am not able to achieve excess power, greater than the input.

I'm really curious now how a Chaos-Pendulum would perform,
if the weights were in tubes......

Dear Sir,
We will have to use the absorbed energy in the spring to tilt the device.if we could use this absorbed energy then there will be no need of extra energy to tilt it  and device will sustain it's momentum.

Even if we perfectly balance momentum and springs
There is still friction and wind resistance.
even though the total change in (mgh) =0
I think it is the same as just spinning a wheel


It just seems mathematically confusing.
I was incorrect by using the wheel analysis
To use that, the weights must revolve a full circle
around the axis.


The lever analysis gives the correct answer.
Change in E is -

Each time the ball moves, the center of gravity changes
