Yeah, I agree, anything with the magnetized ball bearings is superb.

Magnets?

I'm always curious about the 'free energy' claim.
Even if it's not expensive, it won't be 'free', and if it is so perfect that it's free, what happens to the millions that work in the energy field today? I'm not suggesting that issue is in any way a reason to not go forward, just that it's an issue that must be dealt with in the eventuality that 'free' energy becomes reality.
They should hype it as possible 'cheap, efficient, clean energy', never 'free', imo.

Are there any reactors trying to use both methods....magnetic confinement/compression and laser compression combined? It seems like they could use much less powerful (and less power consuming) compression/heating devices if they used both together.

I think his rope is already split into 3 pieces, connected by small magnets. Two longer pieces, and another smaller one measuring 1/6 or so of the total. He cuts of small bits only at the 2 ends without magnets. Need to watch it more for the rest..

Using a trubine in a vacuum doesnt make any sense. I thought it was magnetically driven like the bullet train.

way cool

The can being non magnetic I thought the magnetic field would just pass through it.

Ahh, but the magnets don't actually *disintegrate*... Maybe "centrifugal separation".

Still, I like the cut of your jib.

@Payback -- The Youtube comments area is not to be considered a potential source of rational discussion.

Assume that one concedes to your point about "terminal velocity" being the wrong phrase to use here. What would be better? And I'll note that there are many potential metrics for "better" -- conveying the correct idea precisely, doing so in a concise manner, etc.

"Neodymium Magnets Reaching a Velocity at Which the Centrifugal Force Upon Them Exceeds the Magnetic Force Holding Them Together" makes for a more accurate title, but might lose brevity points. The "Terminal Velocity" title conveys maybe only 75% of the accuracy of the more precise title, but with a greater than 25% savings in length (5 words vs 19). Although I'm sure a more optimally brief AND accurate title exists.

Not trying to be snarky, and I 100% agree that there are situations where saying something with complete accuracy and careful precision is extremely important. But perhaps an online video about magnets spinning apart can be at least partially excused for opting for brevity over accuracy, especially in something as trivial as the title. Especially when the inaccuracy can be noted and explained in the comments section by well meaning viewers.

True, but "terminal velocity" conveys decently close to the right idea and there isn't any specific word that means the speed at which magnetic force is overcome by centrifugal force. As far as I know, anyway.

Escape velocity ("the lowest velocity that a body must have in order to escape the gravitational attraction of a particular planet or other object") might be arguably closer to the mark, but gravity is not the same as magnetism.

In regards to it not being a single take/cut, to me the video looks like someone was experimenting with what they could do. It would cost a lot to buy enough of those little magnets to pull it off in one, and it looks low budget though i say that affectionately. Some of the stuff is absolutely ingenious.
