What exactly is the problem with these devices?

[Rosphere]

I have been doing some research into PMMs for about a year now.  I have been reading watching other peoples creations and sometimes I wonder what they were thinking when they built it.  So far the best devience I have seen is the one Sterling D. Allan created.  So my question is what is problem with these devices?  What is the one thing that keeps them from becoming main stream?  I?m 18 years old I sometime in the future plan on building my own.  I think that one day this could work.

Metastability; I think that control is the problem with these metastable machines, like squeezing a wet soap bar.

We are attempting to tap finite amounts of an enormous natural vacuum energy.  It hides behind a thin, yet tough, vial.  There are many ways to do this, (or so I have heard,) but it must be done exactly right.

Today's internal combustion engines are stable: still able to run with a lean or rich fuel/air mixture and only stopping at the extremes to one other stable state: stopped.  Stable-running, easy to control, and forgiving.

Metastable machines are unforgiving, like a woman.  You need to treat them just right to get the performance that you desire.  But if you cross the line, you may experience a life changing event for the worse.  Sort of like a sticky window; hard to budge, yet easy to throw open--do this with the vacuum energy and it will destroy your machine, and maybe even you too.

Some devices, by the nature of their configurations, may offer better control of this metastable condition than others.  We, at the very least, seek to control devices which have a failsafe to a stopped condition if falling out of "tune," or if any one component fails.  Magnet motors appear to offer this quality: runaway acceleration will meet with increased bearing friction before shaft meltdown grinds it all to a stable stop.  We do not expect any crazy EMP type of events with this type of device.

Welcome to the forum, young man.

standing by for the omnibus smot injection.  Hayden...I have several non working designs that i would have sworn that i have solved the gate problem.  You are young, i am 52 you will see it in your lifetime and it might be you that solves issues...welcome to this obsession for OUFE!

well like i have said before i think some people that create these devices are trying to make them too complex. I have a few designs in my head that are simple but some are close to other peoples designs just a couple of things changed. I would like to build a prototype but one problem is money working three jobs and college and be a drain but hey it will pay off one day.  Speaking of money does any one know of any small grants for projects like this?

Simply put:
Magnets which is not changing magnetism on demand, cannot induce rotation or work. An electro motor is working because of the change of magnetism. All electromotors, even those running on DC-power supply are in fact AC-motors inside because they allways are able to change magnetic polarity as they rotate. That's why they work, and permanent magnet motors does not work.
If you even add loads of energy into DC electro magnets, as long as the magnetism does not change, they will just consume energy without doing any work. So how to make a permanent magnet motor to work, is to me a big puzzle.

But never give up. It's very educating to learn about magnets and magnetism, even if you should fail in your projects.

Actually, you don't need to switch polarity in a motor to create work.
You can design the motor to let a magnetic rotor chase a rotatating electromagnetic field.
This will just cause pull on the rotor, but not any push.
Just like any electric motor but efficiency and power density is dropped due to the missing push.
But still there is work being created. No need for AC fields, just switch the electromagnets ON and OFF.
