Basically, science really needs to provide the educational principles that will allow everyone to understand that a perpetual motion machine is really a concept, an unobtainable goal that is used as a bell-weather so we can measure just how efficient any closed mechanism or process may be. There should never be any discussion about achieving it, for that automatically becomes pseudo-science. This fact needs to be emphasized ad-nauseum in schools.

Seriously fascinating stuff here. I wonder why they don't sell simple stuff like flashlights with this technology?
Who says a perpetual motion machine or if you will a long running "free" energy device has to be a closed system? Why not several closed systems working together or an open system that's uniquely designed in ways we haven't thought of yet?

A sound understanding of the lingual nuances related to physics & engineering would enable you to understand the concept of a closed system and why a perpetual-motion device(PMD) can only be considered such if running in a closed system.
In this case a closed system means that the PMD can not receive an energy input from an outside source. It must power itself without any assistance at all and produce more energy than it consumes - It must have an efficiency of >100% to overcome any friction/loss.
II. Thermodynamic systems
Energy transfer is studied in three types of systems:
Open systems can exchange both matter and energy with an outside system. They are portions of larger systems and in intimate contact with the larger system. Your body is an open system.
Closed systems exchange energy but not matter with an outside system. Though they are typically portions of larger systems, they are not in complete contact. The Earth is essentially a closed system; it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero.
Isolated systems can exchange neither energy nor matter with an outside system. While they may be portions of larger systems, they do not communicate with the outside in any way. The physical universe is an isolated system; a closed thermos bottle is essentially an isolated system (though its insulation is not perfect).
Look at the video of the Free Energy Magnetic Moror.. the CPU fan and magnets from the hard drive. The only way you cant have this do electrical work that would cause the system to stop is if your getting that electrical energy from the magnets themselves that are spinning the wheel. I don't propose to do that. I propose to put a shaft on the spinning center of the wheel and then add magnets and a coil to the other end of the shaft - a totally separate system independent of the spinning wheel and it's magnets you see.. ( except that the other end of the shaft is being spun by that device) This creates electromagnetic induction to produce other electricity. That is the energy that can be used. This never crosses or upsets the fields of the spinning wheel and it's magnets so it won't stop the device.

OK so lets break this down into small bites since you can't seem to digest big bites. The second you just slap on a secondary shaft with magnets and a coil it will require REAL PHYSICAL WORK to generate the power.
Physics does not respond to semantics.... No matter how you phrase this idea it still won't work. Where you got the impression that electrical work didn't require physical work to create is beyond me.
Science only contradicts the functionality of a "free energy" device in a closed system. If the system is open, not only is there no problem with the laws of science, but such devices have already been invented, for example this device runs based on an open system, and needs no electricity to run until the bearings wear out:

Please explain the difference between rare earth magnets and semi permanent or permanent magnets. I have a rare earth magnet and it's a permanent magnet, isn't it?

Like I said you can't fool physics with clever wording. Just because you don't consider a separate shaft running a generator under load (aka charging a capacitor) requires a definite amount of work which PMM's can't do without winding down and eventually stopping. Heck even you have agreed this is the case at one point or another in this thread.
You know how prosecutors and judges will tell you ignorance of the law is no excuse?
This whole argument falls under the same category. You are arguing from a position of ignorance stating that things can or will do things they just plain can't or won't do. In addition you're arguing that because you renamed work to electrical work that it changed the fact that PMM"s can't function under load and keep spinning.
LIke I said in my first post in this thread. I'm on your side I really think there are technologies out there that can revolutionize humanity, but permanent magnet motors probably just aren't one of them.
Also just as a post script here try looking in a dictionary or science book for a separate entry for electrical work and normal work. You won't find on because work is work and PMM"s can run they just can't do work. Connecting the motor to a shaft to turn a generator is most definitely doing work.
