Just to be clear: this is NOT a hoax. The maker is explicit that his devices are not real PM: he makes mechanized 'realizations' of concepts from throughout the history of the search for PM. It's a brilliant concept - I know these devices are impossible, I know they are fake, but when I see them I still have trouble figuring out why they don't work for real. They look so intuitive! It's genius.

Interesting concept. It does show how quickly momentum can change.
If it is real and I didn't see anything to make me think it isn't, maybe people will lighten up on the "it won't work" routine ?

Brilliant love it looks like it should work it also looks like 1717, you know what i mean, if this is a con then i have been conned ,why does it not work, every thing really does seem to make sense ,oh did i just expose my stupidity , what the hell ,very interesting the weight rolling back would cause the lifting weight to do its work ,the issue for me comes when it lands it would need to apply its weight on to a ramp,here it shows a plinth, which would have to have enough effect to push the ramp down to reload the system ,a magnet would help i feel ,i keep the awareness of the pendulum effect and the lifting weight on the left moving to a lighter position ,some body educate me please this looks so convincing ,cheers.

I hope everyone doesn't mind my explaining how or why this works. The bearing is heavier than the washers.

edited to remove unnecessary dialogue, was being long winded. Still, this makes me feel good about what I'm working on because of done a lot of math as well :-)

[ME]

I think the washers should be slightly heavier, otherwise it wouldn't come down when the washers and the bearing have an equal distance from the center-pivot. I guess the hinged lever is supposed to be heavier which is counteracted by hitting the bump.
Then things go perpetual until the parts wear out (like a battery for the EM-repulsion for example)

[AB Hammer]

The ball will never have the leverage for it hit neutral at the end. Blunt is not leverage for the ball.

[james.lindgard]

AB Hammer and ME,
When the ball lands on it's stop, the washers continue upward. This is because they conserved momentum from the ball moving downward. When the ball is rolling inward on the ramp, the ramp is not lifted. Why ?
It is because the ball is heavier. And then when the washers have more torque or leverage, that side starts dropping yet the ball does not start rolling out again. Why ?
When the ball rolls towards the bend in it's lever, it has both linear and angular momentum. It is conserving it's own momentum as spin. And when it stops at the bottom of the ramp, it's angular momentum holds it in place just as it's linear upward momentum allows the ball to momentarily lift off the lever when the lever stops rising.
This is an excellent way to understand how the physics of momentum plays into Newton's Laws of Motion. And I think that's why I find Infinite Oscillation pretty cool, the science in it is pretty amazing.

p.s., AB Hammer, as I said years ago, there is an invention worth money but you seem to have little interest in inventing or making money. We'll never be friends but I'm not against making money while you seem to be.

edited to capitalize a letter. kind of a pun because to make money off of an idea is to capitalize on it just as taking a letter from it's lower case to it's higher case is capitalizing on it as well.

This is absolute nonsense. All that will happen when the ball rolls to the extremity is it will overbalance the washers and come to rest on the block.
There is nothing there that will cause the ramp to carry on falling until the joint hits the deck. Trickery me thinks! Possibly a magnet under the elbow joint periodically being placed and removed by someone. Hence the slight wobble half way through the film suggesting bad timing by the trickster.

I agree it is done most likely with an electromagnet or a another possibility of a control arm in the middle for the pivot is set to one side. Anyone who would take this as a possible working device has not done their homework.

[ME]

While we are here, I could be interesting to think about how he pulled it off.
I think the electromagnet holds the hinge long enough to let the bearing drop, and then reverses polarity as things jump up. Maybe the rest could be still be mechanical.

[KAS]

I actually think the electromagnet (if that is what is being applied) is is being switched on and off manually. There is a distinct lack of rythm to the function which you expect if say the bearing hitting the block triggers the switch. I would suggest manual operation - maybe even someone placing and removing a conventional magnet.

[james.lindgard]

This is funny :-D
With the "capture", the force of the extension and weight would be 1/2 on the pivot and 1/2 on the stop. Still, there is a way it could work. Just add a pendulum :-D
A pendulum would hold the arm tilted while the bearing moved. And then when the pendulum swings the other way, it would help to lift the bearing and extension. In this capacity, a pendulum would act as a flywheel and store momentum so that movements can be timed.
I was kind of hoping someone else would think of this. And if the pendulum's shaft is flexible, then it's movement relative to the cross bar will have some "play" in it.
And if this "innovation" I thought of is something that can work, then I just invented a Perpetual Pendulum.

edited to add; p.s., a pendulum can also be geared so it's movement can be more or less than a cross bar. Even a slip joint spline might work. With such a coupling, it's swing could be more than the movement of the cross bar although I like the gearing and flexibility option better.

[KAS]

I like you chain of thought James.
The only problem I can see is that the ball would need to be heavier to move the counter weight plus the pendulum weight out of balance in the first place.
This would throw the whole ratio out as if the ball needed to be heavier, so must the counterweight (washers). Paradox.
It would balance pretty quickly imo.
