For an animation from 1992, this looks amazing.

Hello! I am a student of engineering in Spain, I am completely amazed to see this!,

This simply paves the ideas for a road that humankind has yet to move on. Soon, it will be time to show what we really know.

Dude this guy's subscriber count is caught up in anti gravity. Never goes up or down I tell ya

My father came very close to 'perpetual motion' type of machine. However it relied on free swinging weights. On one occasion he only had to give it a small push in the right direction and it would speed up, then come out of timing. I counted twelve revolutions of acceleration before it flew out of sinc. I have no doubt at all that PM (type) will one day be mastered and deliver a lot of positive power output.

I was also so surprised of its balance! Thanks Andy!

Which is?

ahaveland, you have impressive demonstration, I have come out with the almost same idea as inertial proportion as you have here. The primary reason this may be going to work is that we get different angular velocity of weight add at different distance from axis, result in acceleration of mass and produce force, when it spin upward, distance of mass further from the axis, angular velocity increase(provided the flywheel can keep it constant angular velocity). (continue next post)

I know it wouldn't work but if someone built it.

Ars did exactly what your device does . I built functioning model that created an unstable torque issue but I recently figured a way to stabilize this thing . I've got several mechanical devices patented and in use. I would be happy to collaborate with you on this , your a genius I assure you.

I'd love to see this vid redone--beginning with a brief explanation and diagram of exactly what's happening and why it's noteworthy.

its a work of art

I like your thinking. I built a similar machine in the 90's as proof of concept. It does work the problem is it must spin very fast for much benefit. Mine was built on a small cart and the inertia is variable to prove it is not just shaking itself around. I believe these mechanisms (I call DIM or Directional Inertia Mechanism) are what will make interstellar travel possible. The first practical application would be multiple DIMs in a thrust-pack for extravehicular jaunts by astronauts. keepitup

it can also be used as a gravitational pump, using enough out-of-balance gears around the central hub and orienting the wheel with the weight tangent to the external circle (the one that would give the direction when the mechanism would be used as an engine) at 90 degrees to the gravitational force.

WOW! Well I'm sure that would work son. You go on and build it now. That's some cool shit right there!
