Does anyone here have experience with these? I'm in the process of gathering and machining everything I need to build one, and would like to be able to use it to spin an alternator, essentially generating electricity for next to nothing.

I have all of the magnets, I'm going to try it with strong rare earth magnets. I'm currently experimenting with the angle of the magnets, which angle generates the most push. I'm using rare earth magnets for their power, and hope to build one with a decent amount of torque...hopefully enough to spin an old phone generator in the future. The wheel I'm using is 36" in diameter, so the centrifugal force should be enough to do it.

I'm using precision needle bearings to mount the wheel, which, in my experiences in the past, are one of the best bearing styles to use in this application...very little friction, so I should be able to reach some fairly high RPMs.

I'll be using a flexible coupling to attach the 80 amp alternator to allow for any minute differences between the two.

I'd like to be able to get this to charge a bank of automotive 12-volt batteries at first, then locate a decent generator and produce DC current.

I'm not sure that this will eventually go anywhere, but it should be fun. Part of it is for personal reasons, and the other part is for financial gain.

I know that the average lifespan of a permanent magnet is about 300-500 years, depending on temperature, but I'm trying to figure out of the power drops off suddenly or if it gradually drops off, and at what percentage.

I've studied as much as I can find on the internet about Howard Johnson's Spintronics, but there seems to be some information missing from the 'net.

Anyway...has anyone here delved into something like this?

Is there a reason that you think a "HoJo motor" will allow you to generate "electricity for next to nothing"?

It consumes no power, operates on permanent magnets, and has the potential to power a generator, producing electricity...what is there not to like? It's the closest thing to a true perpetual motion machine.

Do you have a reason to believe that it will actually do what you just wrote there?

In my original post, I stated that the wheel will be large enough to provide enough centrifugal force to turn the alternator, my first experiment, at the required RPM and then some. My hopes are to make it work with a generator to provide DC.

It's hard to beat the laws of physics.

Energy is conserved.

The nineteenth century law of conservation of energy is a law of physics. It states that the total amount of energy in an isolated system remains constant over time. The total energy is said to be conserved over time. For an isolated system, this law means that energy can change its location within the system, and that it can change form within the system, for instance chemical energy can become kinetic energy, but that energy can be neither created nor destroyed. - wiki

The energy from the magnets, pos versus neg, is turned into kinetic energy, which in turn is transformed into electrical energy via the alternator.

Basically, it's trading one form of energy for another, multiplied. The initial start up energy would be my hand starting the wheel into motion, the magnets take over from there.

Anything that could actually provide free energy would already be happening in many locations. It's not going to work. Electric motors work because the magentic field changes position as the commutator goes under the brushes. Permanent magnet motors have one half of the equation permanent magnets, the other half the changing electomagnetic field.

Is this thread just pulling our collective leg?

With today's technology and materials, it may be closer to happening...This ought to be fun!

I'm a toolmaker with a mechanical engineering degree...I design and build machines for a living. My experience includes automation, small turboprop engines, heat seal machines, and lately, industrial fluid pumps. This is the type of work I love.

The potential is there, and was researched by Howard Johnson, the father of Spintronics, prior to his death in 2008. The research I've done has come to a road block, as I'm not willing to pay for his plans and research, so I'm on my own here. The theory is out there, and videos of other machines like this are all over YouTube.

This isn't a joke...

No I have seen it being promoted reciently. You have to believe in perpetual motion machines and I cannot do that. I would like to be disproven though.

That there is always a loss occuring in energy transfer is absolute. I have enough working background in electronics etc and enough of an open mind to examine almost any concept.

If you want to share what they suggest as a working thesis please do. Magnetic force fields etc are well understood by many on site.

The closest example to perpetual motion I have ever seen is getting the wife upset. Does not take nearly the input energy that she puts out when I do.

One of my losses in life was I had the chance to purchase and develop a high waterfall once. This was before the local hydro company would purchase surplus power. In those days there was plenty of surplus electrical generation equipment around at scrap prices as well.

The system plans and description are ten to twenty dollars on the ad runing right now. I cannot tell you where as it was a pop up a day or two ago. It was a creative pop up that was fairly hard to get rid of as well.

The ad is full of the usualy mystery approach with a few more spins on it. About the same as why the two hundred mile per gallon carborator is supressed by the auto industry. Instead this time it is the hydro industry doing the suppression. The only certainty is that if it works you will have people beating a path to your door.

The world has been waiting quite awhile remember for anything that does work. So far zilch to the best of my knowledge yet I try to keep an open mind believe it or not. I will go to utube and have a look at spintronics though. As always I could be wrong. The last time I knew everything I was two years old.

Iran into that ad this afternoon. I've seen others offering them for $200. I don't plan on buying them, as it's a ruse, but the idea and fact that the machine actually works isn't. Making them generate electrical energy isn't a new idea either, but hasn't been proven to make enough to be beneficial yet.

Below is the video that got me thinking about this...

Site with the hype is www.mag-power.com. Before investing countless time in the large unit. I would build the small unit on the old cd disk with perimeter magnets and a small dc motor with no load as shown on one utube. On u tube he shows a flickering small light bulb as a load. If you can get any form of continious running then move on the larger unit.

I just do not believe what I am seeing on the various u tubes. Again I might be wrong. Make the cd motor work as we can trust you and you will have some company on your venture.

I have been weighing if it could be involved with the earths magnetic field in some form of parasitic way. I do not know if the earths magnetic flux is in constant motion for example. Yet this indicates it is. I doubt anyone that has built one of these understands it totally if it works.

That working is still a big if as well. I am in no way a smart ass type of guy. Consider doing the mini model first. Far less than half a day should do it. If it works it is getting energy from some external component in my opinion. It cannot make it's own energy.

That external force or energy source should be the earths continious flowing magnetic field but I would have to think about it for awhile. I am kind of glad you posted this thread. New things and approaches are always interesting. Once again I can easily be wrong. Magnetic fields do expand and collapse of course as well. It takes energy to enable repeating this though.
