Self Contained Power Source? 397
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."

What is most sad about the story is that it appeared on the front page of Slashdot. "News for nerds" turned into "News for idiots". This leads me to believe that if even the supposedly scientifically minded Slashdot editors and submitters are willing to believe such crap, the general public will probably be even easier convinces.
Sad, sad, sad... I blame the primary education in this country.

Want to increase efficiency over 100%? Start with a motor that has 40%, make one that is 80% efficient - you got 100% increase!

You could assume to you would be cutting 4 minutes from your mile.
If I were to say
"This will increase your runnning speed substatially, over the 4 minute mile barrier"
The assumption would be vastly different.

100% isn't a barrier if it's a relative increase, as you correctly point out. It is a barrier if you're talking about absolute efficiency. By talking about it as a barrier, the author almost certainly intends for us to read it as "100+% absolute efficiency."
I'd be happy to be corrected by anyone affiliated with the posted site, but until then, I strongly believe that they're talking about a motor that's more than 100% efficient. Which, given a few caveats as discussed in this thread, is accepted as impossible by mainstream science.

Even the title reeks of faddish words. Remember last year's warm fusion fraudster? This year is mirroring Cell processors and the tech that it uses.
It makes me wonder who is really submitting these articles to Slashdot.

the key point it if there is any net gain at all. The static force analysis simply does not give the answer. As I said adding a spring would do exactly the same thing as adding a permenant magnet. But then it becomes obvious that there no net gain because the you had to pay the effort of loading the spring.
Since they rely on this static argument without giving a dynamic argument it seems like bullshit to me. My bullshit detector is further raised when they present the finite element calculation to back up the static arguments. It's a huge calaculation that backs the worng argument. this is just plane weird. it looks like a delberate attempt to inject bamboozle ment into it. Do they know what the hell they are talking about? Then where's the dynamic analysis?

The iron filings move because you're moving the magnet. Don't move the magnet? No little iron filings moving.
The exception is when you first bring the magnet close enough to the filings to make them move. They will move towards the magnet. That movement is due to their potential energy (energy of position). Now, why don't we harness that? We'll just move the filings away and drop them again... oh, wait, that will take the same amount, or more, energy as we get out. Okay, let's turn off the magnet and them move them away. Oh, wait, you can't turn off a permanent magnet. Okay, we'll use an electromagnet! Oh, wait, the electricity it takes to run the electromagnet is equal to or more than any energy we get out. Oh well.

If we could get some investors to back us, we could build a space ship that could go out and collect all this free "vacuum" and bring it back to Earth.
