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."
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.

I love how the "Lab" in the picture looks a whole lot like a kitchen.

Whoo, signature!

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.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.

The only natural law involved here is "There's a sucker born every minute".

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.
