Video of YAPMM (Yet Another Perpetual Motion Machine)
Enjoy this video of a perpetual motion machine in action. I don't believe it for a second, but it's fun to see the thing in action and listen to the guy's patter. Also, the sound the wheel makes as it spins is pleasant. Link (Thanks, pooty McDooDoo!)

So its my understanding that perpetual motion using interactions between small magnets has been shown to be impossible? My question is what kind of shenanigans is this guy using to get the center wheel to spin so fast?
I almost bought it until I realized that magneto-kinetic Judson dampers are incorrectly polarized for that gauge of stator!!!!
How embarrasing.
Well the odd pulsing from the orange light and humming item certainly set the tone for sci-fi.
An electric motor? A miniature gas engine? Flubber?
I'd like to see the bottom of his device.
If this is a perpetual motion machine, why isn't it running when the video starts? I suppose he had to demonstrate how it works, but if I got one started, I'd certainly not want to shut it off.
I suppose that's why I'm not a scientist, though.
So, he can build a machine that violates the laws of physics, but he can't operate a video camera and an overhead light well enough to say...umm...take a decent picture of his device. Or even illuminate the display on his little RPM meter. Or actually discuss it coherently on camera.
Uh huh.
Amusing indeed.
I have no idea how this thing works. It isn't a perpetual motion machine, of course. It might make a nice magnetic fly-wheel, which can spin for hours, but eventually slows down and stops. I wonder how long this PM machine has run before un-perpetual?
That video is a repost to brighten the original a bit. If you follow the link to the original ( in the comments for the link posted ) you can read in the poster's comments that it is NOT claiming to in fact be a working MPPM.

@Bret - Getting the center gear to spin fast isn't the problem. The real question is 'for how long?' The magnetics exert a force at a right angle to the motion of the center wheel and will require more energy than they generate to sustain the speed.
Amazing how this device looks like the Steorn one...
As with all physical systems that we know of, the maximum amount of energy we can get out is equal to the amount originally put in. My guess is when the device "syncs up" is the moment when the battery pack is turned on. When you have acceleration like that in a system you need some sort of external energy.
#7, according to an entry in the Pure Energy Systems wiki page (linked from the blog entry that BB linked to), "Something apparently causes the device to stop every few hours"...

In other words, this is a perpetual motion machine only for small values of "perpetual".
the wiki article says it stops after a few hours,
so not perpetual. but really really cool.
I'd love to have a device like this.
It looks cool, and appears to "work" well (as opposed to many other perpetual motion machines than never quite start)
Of course it's a hoax of some sort but if the batteries were well hidden; it could still be a lot of fun
Here is the Steorn thread:

This is not a perpetual motion machine, however, it is deceptive. It is deceptive because the real driving mechanism is hidden from view (possibly a magnetic driver undernieth the table.) He stands to make a lot of money from investors though.

Is the audio mucked up for you too?
Replication, Replication, Replication.
For everyone unfamiliar with it:
http://en.wikipedia.org/wiki/Noether's_theorem
"invariance with respect to time translation gives the well known law of conservation of energy"
In other words, the fact that the laws of physics are the same today, tomorrow and yesterday implies conservation of energy.
Even if fundamentally in some sense the mathematical framework of the Noether Theorems is insufficient for the theory of everything, then these mathematical frameworks are still good enough to describe all observed phenomena within regimes far exceeding those this toy probes.
The impossibility of perpetual motion (in flat background space time) is probably one of the strongest statements possible in science. Meaning it's stronger then the statement: "If I let go of this apple it will fall down."
Certhas said, "The impossibility of perpetual motion (in flat background space time) is probably one of the strongest statements possible in science. Meaning it's stronger then the statement: "If I let go of this apple it will fall down.
If you could have flat background space time, that would mean no mass, and that means no gravity. In that flat universe a perpetual motion machine is not allowed to exist, since it has mass and would then have gravity, and that would put a little dimple in spacetime. The very thought of anthing lasting forever is a null-concept. At least it is for humans.
As I understand it you can actually build a motor of sorts from rare earth magnets but they have no torque. I think that is what Steorn did and so makes them deluded rather than con-artists. The problem with such "motors" is that they repeatedly place the magnets in opposition. This wears them down (they either degauss or become saturated) and may be why this device is slowing down after a few hours.
according to the original youtube posting (now removed) -- the author DOES NOT claim that it is a perpetual motion machine, merely that it is an interesting anomaly.
Heh, I should have known to be more precise here *g* Okay:
As long as the systems mass density is small enough that its complete gravitational behavior can be accurately modeled through first order perturbation theory using g_{\mu\nu} = \eta_{\mu\nu} + \epsilon h_{\mu\nu} with \eta the Minkowski metric.
Alternatively: If the gravitational interaction of the system can be modeled entirely as a geodesic motion.
Or if spacetime is asymptotically flat.
Which incidentally includes pretty much everything we have ever measured I think.
As conservation of energy is tied to the structure of time, it is no long valid in GR which itself is a theory of the structure of spacetime. It remains valid in certain scenarios in different senses, eg the first case has a notion of energy similar to our standard one, the second one has a purely local concept of energy, valid only along each geodesic, and the final concept of energy is purely global and not the sum of the energies of local systems.
There is no energy density in the solar system significant enough to create even measurable, never mind exploitable effects to this end by a many orders of magnitude.

the only source of perpetual motion is our desire for it
Everybody is so skeptical! I'm completely willing to believe that if the geometry was correct, and the polarity axis of the stators were synced as he said that this thing would spin.
I could see how 3 stators would provide more force to get the spinning to happen, but any slight mis-alignment would probably limit the rate it would spin - which would give credence to it accelerating when two are stopped - synchronization is no longer needed.
I am not sure though why the two stators don't introduce drag once their spinning is stopped - I'd think they would have to be removed from the field, but they are not. Anyway I'd guess you could get more rpms and more torque out of more and properly placed stators, but it would probably benefit from a microprocessor controlled servo positioning them precisely - once somebody understands where they need to be positioned!
More interesting is people seem to be willing to claim the physics are impossible, less willing to call the guy a liar!
> the sound the wheel makes as it spins is pleasant
I think it's interesting that Mark said this...precisely because sound indicates a dispersion of energy. i.e., it can't be a perpetual motion machine.
:)
This machine has already filled a patent in Argentina:

(the applicant has to pay a fee for "final review", but he didn't. I think he won't do it.
It would be interesting to see if someone could use a setup like that to draw from magnetic decay directly...
Wow, this comment thread has a lot of very knowledgeable posters in it. I just wanted to comment that the name of the person who sent this in made me laugh. Pooty McDooDoo, haha!
Such cowardice shares a good portion of the blame for perpetuating the current energy crisis(along with price-fixing.) The number of so-called "laws" broken by far exceeds the number postulated throughout herstory.
Think for yourself and then act on what you know directly. A video should not be enough to convince one way or the other.
Certhus said, "As long as the systems mass density is small enough that its complete gravitational behavior can be accurately modeled through first order perturbation theory using g_{\mu\nu} = \eta_{\mu\nu} + \epsilon h_{\mu\nu} with \eta the Minkowski metric."
Is this testable? Finding a mass density small enough that it's behavior can be modeled to what extent? Quantum mechanics has limits with regard to mass and gravity. What if gravity is a result of spacetime, independant of mass? What if higgs bosons (the field) always make friction an issue?
I have a design for a energy device and need to use a cad system to plot a draft so that I can have parts made for a prototype. Is there a cad system that can be used by an amateur and not cost a fortune. I'm not saying its possible to build one that works but looking at the designs I cannot figure out why this one wouldn't. So in order to have peace of mind I will have to build it to see one way or the other. If it doesn't work I can get back to the rest of my life with peace of mind and if it does work either I will be fantastically wealthy or the CIA will have me whacked!
Take a CADD class at the local community college and use the school computers to do your "homework".
