Bearing confusion

[chrisofnottingham]

Well, since PM is fundamentally impossible people have to come up with bullshit excuses.

Magnets and wheels have been around forever. In the last hundred years we invented rocket science and computers and used them to put a man on the moon. If they can't get a spinning wheel to work over the same period then its never going to happen. And anyway, a cyclic system can never have PM because it has the same energy in the same position every cycle. It will only turn to move to a lower energy state.

don't use drugs!

[lecerveau667]

Chapeau! Genial!!

[weeeendog]

hmmm . . . so . . . what is this supposed to be? as presented . . . completely incoherent

[theoneagain]

and the sad thing is the guys at steorn havent got the guts to come on youtube and discuss or even upload a little video of there system It s all a load of bollocks.

[theoneagain]

steorn had their asses wipped by the supression illuminati

bearings my ass

[ololh4xx]

youtube is fucked up ... i CAN post new comments but i CA'NT answer to comments! Well i´ll just leave the little boy be, he'll soon discover that magnetism and its effects arent "drivel". I really wonder what he may think about alternators ;-)

[ololh4xx]

another test

[ololh4xx]

test

[DonHoraldo]

do an rpm test without the magnet.

[UnderMan1965]

Let's see him do it without the magnet first.

[ceriman]

The tachometer works, and shows that the wheel slows down immediately after he starts it spinning. From over 900 to about 500 RPM in a minute or so.

The "angled magnet" idea keeps popping up, and it still doesn't work.

[p3x797]

fit a dynamo to it

[autograssboy]

does this spin with out any current?? if it does job well done wb

[Soukup2955]

Was soll das sein,????

[theoneagain]

steorn have really gone dead site no longer active online but no mor updates

The men in black havcaught up with them i suppose

[LifesVoyager]

The great thing aout these guys is that their little hobbies help to keep these barking loonies off the streets and tucked away in their home 'labs' where they can do little harm.

[seshkanuri]

No. It may be much simpler to guess - The police have caughtup with him and put him where he belongs.

[theoneagain]

havent heard from you in a while i see you havent gone dead always something to say

[jamesroney]

Shielding my friend, incorporate shielding.

[shockferret]

At 2:35, the tachometer reads 363 RPM when the device is stopped.

[3LITA]

Ah yes, Top Secret Perpetual Spinning Top, also available on amazon for ten bucks.

[BigDriddiford]

If the science is faulty, it may be that the inventors are guilty of not testing rigurously enough. The laws of Physics are not all encompassing, and there are holes, as the general and special theories of relativity have proven. Just bear in mind that for every breakthrough, there are a million who have no success. Doesn't mean you should stop trying.

And Hairhorn? Just necause you can spell doesn't make you smart. Sarcasm is the lowest form of wit, after all.

[IdiotSlapper]

BigDriddiford wrote - "And Hairhorn? Just necause you can spell"

My reply - I think you meant to spell "because"?

Scientist produce science, engineers help design them and an inventor invents. Inventors do NOT create laws of science, faulty or not.

[BigDriddiford]

Ok then, while we are taking things apart, lets discuss. You may have a degree in stating the blatantly obvious, which is why many people have not commented on my mispelling.

Secondly, scientist do not 'produce' science. New laws wait to be discovered by scientists.

Thirdly, engineers 'help design them'. Design what exactly? Engineers use laws to produce and improve upon past inventions.

[BigDriddiford]

Fourthly, inventors produce new methods or ideas to solve a need (possibly the expression you were scrabbling for when you said 'invents').

In past history, every one of these processes has resulted in the discovery of a new law governing the universe, be it physics, chemistry or biology. It may be a limitation of the human mind as a whole that we do not accept a lot of laws discovered by those outside the spectrum of academia, but it may also be snobbery.

[BigDriddiford]

Never forget that Einstein made his greatest discovery while working as a clerk in a patent office, without personal contact with the physics community. He also made fundamental mistakes in his algebra calculations that a child would be scolded for.

I shudder to think what may have happened if he was around today faced with some of the people commenting on this site.

I am no Einstein, but unlike certain others, I like to investigate things before ridiculing or expecting something to fail.

[ms2333]

I agree with you almost 100% except for two statements. Einstein did work as a clerk in the patent office but he had a masters degree and was in regular contact with the physics community. Some of his best friends and colleagues worked for the university in Bern and it was to the academic community that he published a number of his papers (photoelectric effect and others). His first wife was a brilliant physicist as well.

[ms2333]

I'm less certain about the mathematical errors you mention he made but I can tell you he didn't fail maths as the urban myth goes. He was indeed brilliant at it and excelled in maths and science studies. He was, however, disdainful of the scholastic process and mused that (I'm paraphrasing) it's a wonder scientific curiosity survived the process of schooling.

[ms2333]

In fact, his PhD was a point of contention as the university board wanted him to do a dissertation and wouldn't count his other groundbreaking works. He stubbornly refused and this delayed his PhD and professorship that he so yearned for.

[BigDriddiford]

Gotta take my hat off to you, ms2333. I'm not up on some of this as much as I'd like to be. Just using it to illustrate a point is all. I was just saying that it's much easier to make these discoveries if you're in the right evironment, and even great people make mistakes.

I find nothing more abhorrent than willful ignorance.

[ms2333]

oh I think we can agree on that. It's very easy to be a skeptic.

It is well known that a vital ingredient of success is not knowing that what you're attempting can't be done. ~ Terry Pratchett

[flowerbower]

ms2333: point of accuracy. All things are 'relative' (sic): Einstein was certainly a good mathematician as compared to a layman, but he was NOT a particularly good mathematician when compared with other mathematicians and physicists. For instance, his friend, Grossmann, had to help him out constantly with tensor theory.

Efforts have also been made to 'paint' him as being a 'Renaissance-man' because he also played a musical instrument. He did, but not very well.

[clanzer]

This was one of my test rigs.

It is a simple test Rig. Not self running, Not OU.

It should not of been made public and I did not release it.

The bearings are RC bearings Top and bottom.

No Mystery, nothing clever, but it was made to ask a question, not to show anything else.

The point is these little RC bearings have taken alot of beating even though mounted in Polycarbonate and span at very high speeds and are still going, that was the point, nothing more, nothing less

[mickster00]

Is that a proper bearing or a bushing? bushes always wear out quickly and you get a weird noise develop (that sounds just like yours does) as the wheel vibrates on the post.

Get a proper bearing in there if it's a bushing, something like a skateboard bearing with the seals taken out and all the grease removed to get it as frictionless as possible.

Also mount it vertically, it will remove the sideways pressure on the wheel too.

And please fit more stator mognets! I want to see it work =)

[terryeo]

How obvious can it be?  A single magnet in the stator makes the rotor go at a pretty good rate. Two magnets in the stator do what? It is pretty obvious. There is something to the angled, edge of magnet meeting face of magnet, that science hasn't defined.

[theoneagain]

i still havent recieved results from steorn yet . anyone know what has happened to them.

[hairhorn]

wow... a disc that gradually slows down when you spin it by hand. Revolutionary.

[terryeo]

The bottom plastic wheel shows about 75 slots, each of which might hold a magnet. With a single magnet in a single slot, the video present a slight force, spinning the rotor. One can see the possible bearing stresses involved. A low friction, light bearing is wanted to get the thing running, but when running, high bearing stress could develop. Add to this the unknown element, we don't EXACTLY know what happens where two magnet corners meet.

[dareka11]

Check out a 'crank1' on flickr. He supposedly has photos of the kinetica toy and then some. Posted in FEBRUARY 2007. It looks interesting..... but again just another piece of annoyingly tantalizing information......

[maryyugo]

So, let's see what's *under* the table.

[flowerbower]

Never mind what's under the table: how do we know that there is no jet of air playing on that otherwise pointless fan assembly?

Oh, we would hear it? Not if the voiceover/sound-effects have been recorded separately.

[superstitionadd]

The issue isn't wheather or not it's being spun up by jets of air. This assemble will do exactly what it is doing unassisted it's just normal physics, it's not trickery and he doesn't try to state anything overunity is happening. Your comment is ignorrant of the laws of physics.

[flowerbower]

It is accelerating up to speed with no apparent input. The overall implication is that the fraudulent Steorn apparatus was genuine. If you think that objects can behave like that with no input, then you are accepting the ludicrous concept of over-unity. Big words about the 'laws of physics'; you have obviously never opened a physics textbook in your life or, if you did, you were only capable of misunderstanding it.

[superstitionadd]

haha, it accelerates up to speed cause he flicks it! the magnet just keeps it going for a while, it slows down the whole time. Magnets will generate a push in an assembly in that arrangment but they also generate a braking force and eventually slow the wheel.

Use some sense mate. "Big words", come off it.

[flowerbower]

The 'magnet keeps it going for a while'? And I suppose that a cigarette-card in a bicycle wheel also keeps that wheel turning for a while. You obviously think that magnets are magic.

[superstitionadd]

If a cigarette card gave the spoke a little push as it passed just after braking it then of course it would keep it going for a little longer than if it just caused a braking force on each spoke. Thats not thinking it's magic thats just called thinking about it for a minute rather than just blindly following what you are told. Oh and by the way thats not a fan is it, its just the positionings for the magnets. Think about it!

[ololh4xx]

have you ever heard the words "magnetic force" and "dipoles" before? No? Then shut up and go back to school.

A magnet _WILL_ push the flywheel a few hundred times, but it _WILL_ also attract it in the opposite direction even more, therefore the movement stops

[flowerbower]

I haven't been 'to school' for years and, when I last did, I was lecturing - and not misunderstanding (as you seem to have spent your time doing). My current job is to keep this sort of drivel out of textbooks and journals. Try to think more logically.

[metaspherz]

To: Flowerbower. Fringe science will always have its detractors. Indeed, you are one. The few frauds & honest but deluded dreamers will flood the scientific community with their unrequited dreams & theories. But many of those alternative energy devices they promote are legit & deserve recognition. I suspect that before the world was proven spherical many acedemics logically lectured that it was flat or bowl shaped. So think twice about that which you call drivel. Tomorrow it may well be fact.

[flowerbower]

Fringe science is fringe science because it avoids the checks and balances that real science would apply. These nonsense-ideas do not survive because they have been tested, but because they avoid being tested.

And please drop the flat-Earth nonsense; it was generally accepted, that the Earth is spherical, over 2000 years ago.

These people are not fighting detractors; they are fighting every single careful scientific experiment that proves them wrong.

[Crusading4Truth]

If flowerbower is here...1 can be 200% sure it works :)

[lecerveau667]

Qui! FB est un con du premier ordre!!!

[akinadownhillace]

Couldn't you arrange the fixed magnets, on servos to counter the braking effect with the correct timing when the servo mounted magnets to come into range of the disk mounted magnets? The only way it would work is if the electric power going to the servos controlling the magnets, is LESS THAT the kinetic generated by the wheel with magnets on it powering a electric generator. Well that's how I see it.

[emspectra]

Holy crow... this is a working Orbo! the bearing seems irrelevant in this video, as the thing appears to be working!

I cant quite make out the field orientation and the magnetic interactions, as he painted the wheel black...

[xiaou2]

I find it amazing at the lack of common sense from someone who has the capability to construct such a device to high tolerances. Its simply shocking.

[clanzer]

@xiaou2

I find it amazing that you gob off your mouth based on only knowing a small percent of the conversation that this video was part of.

Heat tests etc have been done, this video is one small part of a question.

I CNC my own stuff and do not use a 3rd party workshop, I know how hot the Poly gets when cutting, yet I get a accurate cut each time. Wizz a 2 flute bit across some poly at 20'000 RPM and you will know the heat produced. It tough stuff.

300W halo ROFL do me a favour!

[xiaou2]

Bearings function differently in a vertical

position than horizontally. Also, have u heated the unit up wth say: 300 watt halogen bulb pointed at it? Metal expands with heat. Plastic deforms.

Combine that and drive the unit vertically with a motor at high revs, and C how long it

will perform under those stresses.
