Is the Efficiency of This Electric Motor Too Good to be True?

I think this is a hoax.

they power out > power in.

A maverick inventor's breakthrough electric motor uses permanent magnets to make power -- and has investors salivating

If you've ever read the book "Voodoo Science" by Robert Park (and I highly recommend it), you'll find that virtually all newsertainment stories about perpetual motion start exactly the same way: a maverick going against the "establishment," usually self-taught (as so not to learn the correct science), etc.

As for his "invention," yes, once you see Eout>Ein, you can dismiss it without a second thought, but let me see if I can find the specific flaw in this one...

...yep, a very, very common one:

Apparently the angle and spacing of the magnets is such that once the rotor is moving, repulsion between the stators and the rotor poles keeps the rotor moving smoothly in a counterclockwise direction. Either way, it's impressive.

Yeah, its impressive allright: magnets that don't obey conservation of energy.

Minato assures us that he hasn't transcended the laws of physics. The force supplying the unexplained extra power out is generated by the magnetic strength of the permanent magnets embedded in the rotor. "I'm simply harnessing one of the four fundamental forces of nature," he says.

Although we learned in school that magnets were always bipolar and so magnetically induced motion would always end in a locked state of equilibrium, Minato explains that he has fine-tuned the positioning of the magnets and the timing of pulses to the stators to the point where the repulsion between the rotor and the stator (the fixed outer magnetic ring) is transitory. This creates further motion -- rather than a lockup. (See the sidebar on page 41 for a full explanation).

Translation: 'I understand physics - this is a hoax, not an error.'

This is probably the most common type of overunity efficiency motor hoax there is. Proving it works is trivially simple: connect the output to the input and disconnect the external power. Go figure: no one ever does it. But showing apples=>oranges voltage/amperage comparisons is an easy way to trick people.

Well, since its OVER unity, why not connect the output to the input with a couple light bulbs hooked up too and utilize the 'free' energy to do some useful work. Actually, with 330% efficiency, better get a whole bunch of them. Look, I'm lighting up Giant's stadium from my pocketwatch! :)

Nice recommendation Russ, I'll have to pick that up on my next Amazon order.
