Why can't we get free energy from magnet motors, according to scientists?

If this is sooo simple, why is it not everywhere?

Because it won't work?  Even if you could shield the magnet, you would find that the device would get stuck at an equilibrium point, where the magnet is half shielded and half not.  The see-saw would probably be horizontal or close to it, depending on weight vs. magnet strength.

I think we have gotten a little bit of topic here.
And there is still no logic explanation to read except some old theories and many personal theories with no backing.
Isn't there really any other scientifically explanation except equilibrium points of why magnets cannot provide power.

Will it always take more power to overcome the equilibrium point in every design?
I was thinking of the Sprain wankel motor or the Hilden Brand valve.
These solutions do not depend on magnets interacting with shields or gravity.
They are put to work in a more straigth forward way to do hard work.
The Hilden Brand valve doesn't even suffer from an equilibrium point, what I know of.

Who knows?  While adding magnets to the mix is a relatively modern idea, man has been trying to overcome the equilibrium point for over two thousand years, and it has not yet been done, so sadly, that is the current state of affairs.  I really think the key is to make devices and see what works.  Theory only goes so far, because nature has a way of equalizing things in ways you do not expect.

I don't believe in PM machines where people try to shield or balance it or someother mechanical way to get past the equilibrium point.
Those who manage to find a way will discover their machines to be extremely weak and the slightest load will stop them.
Just take a look at the Finsrud device. http://www.overunity.com/index.php/board,23.0.html
Another example is all of those PM motors that people strangely enough is connecting to capacitors to slowly see a raise in voltage.

What we need is raw power and torque from the magnets. Or just plenty of electrical output at low power input.
If the device is to weak, like 101%, then no one will be interested in commercializing the invention.

Even COP 1.2 is very weak compaired to the high oil prices of today.
Let's say you want an output of 5 terra watt (like a power plant) then you would have to produce 25 terra watt.
And the return feed of 20 terra watt is not an easy task to perform.
The power plant wouldn't be very economical when considering the cost of building and maintenance.
We need big time COP to efficiently suppress the oil dependence, not puny almost non existent OU.

I know I will get hell for this statement but I'm so tired of all those devices that really never works.
And perhaps we will never get OU using magnets. The laws of physics might just be right about this.
