Now that is pretty darn neat!!!
Wow! No more 9v to run my fans. Thanks!
Cool. Where did i put those magnets? ??
I've heard that it also produces a free lunch!
Look closely at video, in final segment, before he tapes on 4th magnet..... why is that corner already taped up? And that is the corner that the wire is running from.
I could be wrong tho, once I saw this video that said Dutch was working on a suspensionless hammock.....
I am so happy to see that the worlds energy "problems" have finally been solved.
I've got a couple of bridges for sale if anyone is interested.
That is amazing...I will incorporate that technology into my car so I can drive for free!
Those of you following the "Hammock magnetism" thread might want to consider that actually using such a hammock may cause you to spin out of control.Attachment 39435
I don't quite understand the naysayers.... People have been making magnet motors for a years now. Look into it a bit before slamming it. I may give this a shot if I can score some rare earth magnets.
I think it's physics which is the naysayer here, but by all means, rare earth magnets are fun (though still operating within the rules of physics).Quote:

This is not a new technology. If you have 2 old hard drives and a 120mm computer fan, you can create quite a breeze with no batteries. Simple physics that works and works quite well. No more hot nights in the hammock - just hang the fan from your ridge line with a piece of wire near the foot end.
So who has made one already?
Your avatar is fitting for the discussion.

You can generate a small amount of voltage from something like this but it is not enough to be something significant for solving the free energy quest. To make this into something large scale will not work because of basic physics. Friction is mother natures way of keeping things from being too simple to solve. But this would still be a great way to power a small fan. Something one should consider though is even with the electromagnets, the fan would randomly stop on its own from time to time when the RPM got out of whack. Not sure if this would still be a problem with magnets. Ill build one and find out. Already got 2 magnets out of an old hard drive sitting in my drawer. Gotta find 2 more.Quote:

Sorry guys. The trick to a magnetic based motor is that the rotor (moving part) has a series of magnets that alternate n-s-n-s-n-s, the coils are activated differentially to pull or repulse the fixed magnets, which rotate, and then activates a switch (in the case of computer fans, a hall-effect sensor) which switches the polarity of the electromagnets, causing the rotor to move again, which activates a switch, which reverses the polarity, lather, rinse, repeat.
I can stack magnets all day long, and nothing will happen... except the North facing magnets in the rotor will align with the south facing magnets.
There's this funny law of thermodynamics: You can't get something from nothing. http://www.physicsplanet.com/article...thermodynamics
In the case of the fan, the video poster has not only created a "perpetual motion machine" but a way to create energy from nothing...(yes, it takes energy to move air) If that were the case, I'd stack a HUGE array of magnets and drive my car, or better yet, power a generator and sell electricity for less than San Diego Gas and Electric, Convert EVERYTHING I own to electric motors, and RULE THE WORLD... Heck, the world as we know it would be very different, and yes, Nikola Tesla would have been richer than John D. Rockefeller.
But alas, I toil like the rest of you... for energy does not come from nothing. That said, gigawatts of power is pumped int the air in the form of radio waves every day. Unfortunately, we can't get that power back, except in nanowatts. (wireless power transmission, what Nikola was dreaming of is grossly inefficient, but I digress)
I'll eat my words if anybody can send me a working model that I can disassemble, and independently verify... oh, I'll send you $110 paypal, too. Then we'll go into buiness and make bazillions of dollars manufacturing fans that move air for free.
There... I said it. Sorry if this offends anybody.
I love that...an offer of independent testing. I, too, will volunteer to independently test and post video results for anybody who has made a "free energy" fan by this method. Like JohnSawyer said, not trying to offend anybody. I would love to see how to make this work, but don't see it being viable.
The energy comes from the magnets, it is not free energy. Permanent magnet motors will de-magnetize the magnets after a while of use. It takes energy to make magnets. There are plenty of examples of working permanent magnet motors out there. The video posted is not the sole example of a CPU fan being run by magnets though. There are quite a few videos of the same concept in work. Does that prove it? No, one would have to whitness it first hand. If I could just get my hands on some magnets, I would give it a shot. I'm a hands on see it to believe it kinda guy. It seems that nobody likes to ship magnets to APO addresses, I'll have to search a little harder I guess.Quote:

BTW, no offense taken here at all. All offerings of critical thinking are welcome. Second guessing and input only improve design theory.
Well, I have some hard drive magnets at the house, which is what it appears was used in the video. I also have several rare earth magnets. Now, if I can find an old PC case fan, I will give this a test run.
OK, here you go guys...this SHOULD (and i stress should, because there are always those who try fly in the face of reason) end all discussion as to whether or not this is possible.
First of all, magnetic fields are not a kinetic (active) energy source. Magnets can, however, be a potential (passive) energy source. What this means is that it's impossible for a magnet to move an object without interference from an outside energy source:
For a magnet to apply force to an object it requires kinetic energy to move the object (or magnet) into the magnetic field. This builds up potential energy, which is again released as kinetic energy when the external force is removed...so the hand in the video is the external force...it spins the fan...the fan can only spin for as long as the hand's force allows it to...that is, until friction brings it to a halt.
Electro magnets require electricity to apply force and regular magnets require a object to move into it's field to apply force on it (in which case, the 2nd object is the source of energy)
...what is being suggested in the video and by some here, is that a magnet can create kinetic energy on it's own...according to our current understanding of physics (specifically, Netwon's Laws of Motion) this is not possible...especially when this specific situation implies that the fan is working against friction (moving the air).
Magnetic fields can sustain a state (floating...etc) but cannot change it without an external force (physical or electricity).
That said, I'll still play around with it because I find this stuff fun to play around with and I know I have at least fan with a burned out motor laying around...but I understand physics and electronics well enough to know that this isn't going to work as described.
The magnets will not demagnetize as though the magnetism is being used up to power the fan.
i never ment for this thread to get like this. all i was trying to say is that a cpu fan would be a good way to stir a little air inside a bugnet, i dont know if the magnets or not. but even if you have to use a 9 volt. to run it i think it will do better than the lil off fan because it uses up 2 aaa's overnite.
Hey, it was done with good intentions and for what it's worth, I'll now be attempting to make something like this myself (just not with magnets of course)...probably powered by a solar panel/trickle charger or something along those lines.Quote:

A computer fan does work well when combined with a 9v battery.
However, I do still have those bridges available if anyone would like a money making opportunity.
I personally love the DIY process and the creativeness that goes into creating gear. I appreciate the OP bringing something to the table that looked new/exciting. Please don't be discouraged by the responses...like I said, I appreciate anything brought to us in this forum.
So I asked my Professor who has a PHD in Electrical Engineering about the magnet fan and he said it is possible. He said when he was younger he was trying to make one but couldnt get the correct amount of magnets positioned just right to make it work for more than a few Revolutions. He then directed me to check out Muammer Yildiz and watch a video on his recent invention. He said that Yildiz has several patents on the new invention and has proven his invention valid in the Scientific community. It is possible to get free energy according to Yildiz invention. You still have to replace the magnets every 20-30 years and the barrings wear out after few years but other than that, the energy is free.
Many people dismissed this invention as a spoof until he tore the machine apart in front of them and proved that it is valid.

Edit: As for the first video posted. I am guessing that it is fake. But the theory seems to be proven true by Yildiz.
