Self Contained Power Source?
McOSEN writes "Your Server Cabinet could have a 100% self sustained power source. It's called Parallel Path Technology and it's being coined as a revolution in the magnetic motor industry. From Segways to Vacuum cleaners to Server Cabinets. The article talks about the technology but doesn't exactly lay out specifics."
From TFA:
1. It's a motor, not a generator. It sounds like it could be a neat motor, but it's still not a generator.
2. "The technology claims to be able to increase magnet motor efficiency substantially, even over the 100% barrier."
That's right folks! It's perpetual motion machine!
So, this is about a motor that makes claims that are pretty universally accepted to be impossible. The poster, of course, is affiliated with the site hosting the page, so he really should have read the article the same way I did. Even if he didn't, maybe ScuttleMonkey should have.
I would be more annoyed, but this fits ScuttleMonkey's past science articles. Could someone send him a few pop-sci introduction texts, so we can stop having the Electric Universe, perpetual motion, and other fringe theories on the frontpage as science?
I hear this was developed specifically for the new Phantom gameconsole and online service. I cant wait to get duke nukem whenever going on that baby!
I thought they were called squirrel cages. And they're not perpetual, someones gotta feed the squirrels!

"Lisa, in this house we obey the laws of thermodynamics!"
So the first lines of the article basicly claim it's a perpetual motion machine, and than later in the article it says this is impossible. Wonderful when even the articles contridict themselves. I really enjoy the part where they state that they recieved a patent, like it actually means something.

Why is it that every new PMM for the last two decades has involved permanent magnets? Is there some kind of mad-scientist cabal that decrees these things? Will the fashion turn to something else soon, like, I don't know, materials so bouncy that they rebound with more energy than they hit the surface with? (Name that classic SF story.)
Seriously: Editors, please shitcan perpetual motion machines before we have to waste precious seconds on them. When a real PMM is possible, you'll know it's happened because suddenly the universe will have stopped working properly, and you'll be instantaneously and very thoroughly dead.
When all you have is a hammer, everything looks like a skull.

If you like exotic motor designs, check out these "thin gap" motors. These brushless permanent magnet motors can reach 90% efficiency, which is very impressive. The windings are made from thin copper plates rather than round wires. These are real. You can order them.
There's some interesting work going on in motor electromagnetics, but the "greater than 100%" motor probably isn't it.
Bullshit detector overload!
This is Slashdot, for crying out loud. We're nerds, we don't fall for this idiotic screed even a high school freshman could debunk.
Ooooh, big words are scary! Stator, rotor, magnetic flux. Dammit, both the editor and article submitter should hand in their geek cards.
This guy does have a real patent, though. I don't know which is worse, the ignoramus patent examiner who allowed this one through or the baboon who posted it to Slashdot. Check the USPTO link here.Like many here, I read the article and got the idea that they were talking about a perpetual motion machine (could be the "The technology claims to be able to increase magnet motor efficiency substantially, even over the 100% barrier." at the beginning of the article that gave everyone that impression...), but the only place that I can find such a claim is from the author of the article...From the way it's written, it just doesn't appear that he knows what he is talking about.
I glanced through the patent at USPTO and it appears to me that what this is is a more efficient electric motor, not something that outputs more energy than is put into it.

It's clear that the writer of TFA didn't understand much about what (s)he heard/read about this. I'm sure that the developers of the technology make no silly claims about greater than 100% efficiency. More likely, this is just an improvement on existing technology that gives, perhaps, somewhat better efficiency, or higher power in a smaller size, less weight for a given power, etc. Any of these would be good, but violate no physical laws.
BSA: "Would you like a free Software Audit"? me: "No, thanks. My software is all Free".
I really wish these kooks could separate the perpetual motion crap from reality here. They are not "over-unity", perpetual motion, or what have you. The do in fact obey all laws of thermodynamics. These motors are real and can deliver as much as 98% efficiency. We've seen them, they work. I was at the presentation recently by Boeing Phanton Works that featured these things. ..Chuck..
*Condense fact from the vapor of nuance*
> Electric motors are already 80-90% efficient, while this might make
> it closer to 100% it won't go over, unless someone discovered some

The only natural law involved here is "There's a sucker born every minute".
Warning: this article may contain humor, sarcasm, parody, and perhaps even irony. Read at your own risk.
Current electrical motors/generators are up to 99% efficient, and the loss is mostly in resistive loss in wire.
/. readers: You have one C++ programmer, and you need more work done. Just hire one more programmer, and to your surprise, you get 4 times as much done.
There is no room for any meaningful improvement unless you claim to have more than 100% efficiency, and they do. Lunatic bin right here!

I was curious as to what they based their claim on?
First, go to http://www.flynnresearch.net/ to se some details on this.
The answer is:
Just doctor up formulaes: Force is proportional to magnetic flux. Se http://scienceworld.wolfram.com/physics/ Look up 'amperes law', 'magnetic force' and 'Lorentz force'. As you can see they are all _linear_. I.e. F=B*k. (Force = Field times some constant. Flynn makes the relationship quadratic: F=B^2*A/2u.
To translate for
"Fix it"
Is it reasonable to assume you can get more output power with better efficiency? Try this article titled
Increase Efficiency 10 Percent and Double Output:
I think the original poster/editor misunderstood the original claim...
They're absolutely right. The submitter was wrong about the subject matter, and the subject matter obviously had many misonceptions about how the technology works (greater than 100% output... WTF?) But here is a look at how the technology actually works. It seems to be a motor that is simply more efficient, which is indeed a positive and achievable goal.

The energy stored in a permanent magnet (from rotated domains held from returning to their equilibrium condition) is called magnetic energy density, and is given in SI units of KJ/m^3. A more common unit used to be the Mega Gauss-Oersted (MGOe). T [1 MGOe = 8 kJ/m^3]. For most nifty permanent magnets, the KJ/m^3 value will be in the 20's to 30's. Now consider the volume of magnets that would fit in a motor you could hold in your hand, and thence calculate the energy density. Then calculate the effect of releasing ALL this energy in one minute, say of a 100mm x 10mm x 10mm magnet, releasing its 0.3 J in 60 seconds, for a whopping 0.005 Watts of power, leaving an unmagnetized lump of metal.
