		<description>I calculated the energy in a magnet once.   Even if you could get it to somehow stay in motion, the energy in a powerful neodymium magnet is very small.   I&#039;m talking about a few dozen joules per cubic centimeter at the absolute most.   As noted above, the most powerful magnets on the market are only 397.9 kiloljoules per cubic meter.   That&#039;s nothing.

It would be a very expensive way of getting very little useful energy.    Worse than wind and solar even!

Getting kilowatts out of it is impossible.   The laws of physics preclude it.</description>

		<description>Well I am certainly not a theorist, but you are certainly a liar: you did not build and run an overunity device.

Claiming that you have is a lie. It doesn&#039;t matter how often you assert otherwise it will still be a lie.</description>

		<description>Drbuzz was the only one worth reading.  You others just proved my point.  You are all (maybe) educated theorists with no hands on.  I have dealt way too many times with the lot of you, and not just in forums.  Rather than trying something, you take what you have learned in school,in a book, at a seminar, on Discovery channel, or just heard someone smarter than you speak, and go from there.  So you are an electrical engineer, who isn&#039;t?  I used to be you.  Thought I knew it all UNTIL an uneducated person proved me, and all written documentation, wrong.

I am not looking for infinity, I am not looking for decades.  I am looking for a simple, non solar, non wind solution for a home in the middle of nowhere.  Do I have to replace it in a year, no problem.  In a week, nah, not good.  I know I will not get 220v 10kW from the motor directly, righht now at least.  But if I can get enough to transform into my needs and power my oven, I am good.  

There is an old saying, ya gotta crawl before ya can walk.

Yes, it was knocked off balance.  That is what happens when you perfectly balance something and some other force shifts it off ever so slightly.</description>

		<description>[quote comment=&quot;19458&quot;]Just a question here.  Besides going off theory, readings, (un)common sense, etc etc, has any of you ever tried this out?  I mean, man once said, and wrote, that a piece of metal would never fly, or float...  So the magnets would cancel themselves, in theory and law and whatnot, but what if they wouldn&#039;t?

Try it, use your intellectual brains to build a disproval then comment that it will not work.
[/quote]

I&#039;m not going to build a disapproval, because I don&#039;t want to spend a lot of money on magnets that will either prove I was right or possibly get damaged.

I&#039;m schooled in electrical engineering so I know ALLL about how electric motors work.  I know the theory and how they&#039;re built and I can design them.   If you think putting magnets in a circle is going to make a magic motor that goes forever and gives you energy then you have no idea how a motor really works or how physics works for that matter.</description>

Bull.

&quot;knocked off balance&quot; my ass.    They will cancel themselves because it&#039;s simple: energy can&#039;t come from nothing.  If you draw energy out of anything it will be limited.   Magnets seem magic but they&#039;re not.   7watts for a month?   I really doubt it.</description>

That does not make any sense.   If you look at the force lines of a magnetic setup you&#039;ll realize it&#039;s impossible for it to be repelled indefinitely in a standard setup.  The magnet simply will land in a point of low opposition.   If the system is low friction, it can give the illusion that it is moving due to some energy, but really it&#039;s just that it has low enough friction for the momentum to keep it in motion for a while.

All the classic designs suffer from this.   The moving magnet just eventually finds a one of the areas of low opposition and settles there.

There has been some effort made to try to avoid this problem by using a system of movable magnetic wheels where any time that the central magnet gets close to settling in an area, some kind of ratcheting mechanism or a secondary magnet moves to stop it from settling.


A lot of design effort has gone into overcoming the problem of the thing just settling into equilibrium, and in some designs this problem has been solved.   When it is, a larger problem arises.    If you can build a mechanical system where the magnets are always in opposition and moving against each-other, guess what happens?   You can get a small amount of energy but you degauss your magnets.   It&#039;s like the classic example of creating a magnet by stroking a nail with a magnet, except in this case the magnet is being stroked in reverse, thus the field is degraded by each rotation.

Many have found this to be the Achilles heal of the attempts.  They spend a long time trying to build a motor that will not settle down and stop.  Finally they have one that seems to be generating its own energy (which it kind of is - for a short time).   They get excited.  Then they notice it is slowing down.  Then comes the final rude awakening:  All their effort to extract energy from magnets has extracted a small amount of energy and in the process their expensive rare-earth high gauss magnets have been destroyed.

You can&#039;t win here.   Magnets can do work, but it must be in equilibrium when it comes to energy or the magnetic field is degraded.</description>

It is that simple.

If you consider &#039;free&#039; to not include having some high pressure sales to buy a truck which was more expensive than I was in the market for.

That&#039;s how they get you!  Now bare in mind that you could probably get a free lunch, a free dinner and a free air ticket if you are willing to sit through a weekend of a very intensive time-share marketing session.

		<description>The calculations on the energy potential of rare earth magnets appears to be correct, but off the top of my head I would have guessed they had a bit more energy than that.  I knew it was low, but that is extremely low.      Permanent magnets were once used in accelerators and that kind of thing in the very early days, but they simply degrade too quickly for any use in modern systems.  They were used to guide ion beams in the very early days of research on much smaller scales but any stress on the magnetic field will degrade the polarity very quickly.   The larger systems use superconducting magnets.
