Super-efficient electric motor
I was reading Slashdot and found this interesting article.

Inventions like this can pave the road to a solution to our impending energy crisis that we will face in the US (and the world) in the next few decades. I can picture vehicles being powered by motors like these with much smaller power supplies and fuel. I'm not talking about running a Volvo on a couple of D size batteries, but a modest fuel cell, or rechargable battery or even solar panel assisted can comfortably power a family sized vehicle and even aircraft. Do you think this will change anything?

or, alternatively, the system is loosing its magnetization.... which will have more issues later...
as far as the rest, this type of propulsion is not new... most high efficiency electric motors don't drive continuously...
If it gets beyond "japan.com," maybe then it's a big deal. Big deals have a way of verifying themselves over a course of media attention.

Bzzt.

There ya go. Energy is energy - the fact that it's using magnetism as essentially 'fuel' is the interesting bit.
It's kind of like the Segway... the gyroscopes allow it to use the potential energy of falling on your face to move forward.
Heck, I can show you how to get unlimited free energy with some water and a 17km sealed tower... uses gravity.

True, but they rely on the coasting of the high-efficiency bearings, this relies on the additional propulsion of the opposing permanent magnets.
High efficiency motors have been around for a while. Outrunner DC motors (these are really a type of AC motor) are very efficient and used as wheels in those solar powered race cars.
P.S. You'd think a motor like this would interest the auto industry but I've not seen a SAE paper yet (SAE papers are usually fairly timely in this regard).

Lastly, if the thing is making more power than it is using then they could attach the output to the input and not bother with the battery. Give it a quick spin by hand and viola! The MG would supply itself with enough power to spare...
Too bad its a hoax though.

There isn't that much energy stored in a "permanent" magnet. If extracting energy from the magnets is essential to the motor's operation, the magnets will quickly be depleted and will have to be replaced or re-magnetized.
There'd be no help here in reducing fossil fuel consumption unless you happen to have a big stockpile of very strong magnets sitting around waiting to become your next non-renewable energy source.

Yup. No argument there. Just pointing out the obvious that there *is* another energy source being utilized here beyond the electricity, before the 'you can't have a perpetual motion machine' babble starts.
But there are a few which look more promising:
http://website.lineone.net/~aarekhu/
This device..actually there are several on the premises...have been operating two decades or more and have been examined by a team of engineers, who said something to the effect of "yes it works according to the claim of the designer/s but it shouldn't (!)".
Inventor T. H. Moray of Salt Lake City back in the 1930s designed "over unity" device which was examined exhaustively and nobody could figure out where the excess power was coming from.
It has been suggested by some that these people have designed devices which tap into the "zero point energy" of the vacuum. This property has been successfully demonstrated experimentally (the "Casimir effect").
When Pons and Fleischmann announced "cold fusion" (what a misnomer!) in 1989 (albeit in a thoroughly inappropriate fashion, no peer review etc etc, very poor scientific method overall), in amongst the garbage there were some anomalous results which, although not repeated, have not been explained satisfactorily. Other "cold fusion" (!) reseachers have noted similar peculiarites. Maybe the energy excesses could also be attributed to "ZPE" as well?Just hazarding a guess here.
I am interested in the subject because of the inevitable environmental and energy crises we face. As Carl Sagan used to say "extraordinary claims require extraordinary proof". All these claims should be examined with the utmost rigor...but hopefully the scientific world is not going to "throw the baby out with the bathwater" in the mistaken notion that "we know all there is to know" about the subject.

Antimatter is more real than these over unity machines though. Every particle has an antiparticle but these anti particles tend to combine with they opposite counterparts within moments of creation. Heck, every nuclear reactor is a little antimatter generator. http://www.space.com/scienceastronom...un_030929.html
sitting near a black hole we get into how hawking suggested a way for the universe to be composed mostly of matter...
the swiss evidently have a super secret way of generating/storing antimatter...
final thought on antimatter -- how did the anti-hydrogen experiments go?
