There is no electrical input what-so-ever it is basically a bunch of neodymium magnets fashioned together in a way around a center which also has neodymium magnets. This is expected to spin with enough energy to power a generator itself and create electricity. All I can tell you is I know it won't work because of research I've done myself; I was simply hoping for a ground-breaking explanation that I could throw at my dad successfully to win an argument.
And by the way I was only trying to be modest when I said I don't know very much about physics. I figured that being on a physics forum I should stand down which seems okay to me... I'm still not saying I'm an expert, but I very much enjoy and understand the subject Newtonian thru SR/GR and some quantum basics.
Here's how I might try to explain to someone why an all-permanent magnet motor is not possible:
In all cases of electromagnetic motors that actually work there is some element of
change, and it is
because of this change, and
only because of this change, that the motor runs. In the simplest motor, invented by Faraday, the element of change is the flow of current. In more complex motors there is current flow,
and, the polarity of the electromagnetic coils is changed at the proper times by commutators or by feeding the whole with alternating current. Energy from some source must be used to cause the change. Generally this is chemical energy from a battery or mechanical energy input into a generator. The important broad thing to recognize is that motors work by harnessing the change that is taking place in their power source. A thing which is not changing does not represent a power source.
The field of a permanent magnet does not change, it is
static. Attempting to make a motor exclusively from properly configured permanent magnets is not much different from trying to make a motor powered by properly configured bricks. Bricks exhibit about as much spontaneous change as the field of a permanent magnet. As long as that field remains static, does not get stronger or weaker, or change polarity, there is no continuous motive power to be had.
The wondrous pulling power the amateur tinkerer feels when he brings two magnets close to each other is as useless as gravity as a source of
continuous energy. Once two magnets have pulled together or pushed apart they remain that way until acted on by an outside force. There is no continuous energy to be harvested here: if you pull them apart they'll go back together, but this is no different than stretching a spring: the energy came from you doing the stretching, it isn't inherent in the spring. The energy in a dropped brick comes from the person who lifted it against gravity, not from the brick. A spring sitting there not acted upon by an outside force will just sit there, as will a brick on the ground.
Electricity, it should be understood, does not emanate from magnets. Magnets are used in generators because magnetic fields have the property that, when moved, they push the free electrons in conductors. So long as the magnetic field is changing; in strength, polarity, or position, it will displace electrons in the conductor causing increased pressure (EMF) and current (electron flow). A magnet at rest relative to a conductor causes no EMF or current. Faraday was a bit frustrated to discover this: there was only current when there was change in the magnetic field. At rest there was no current. The energy represented by current flow, therefore, comes from the energy expended in moving the magnet (or the conductor) or changing its field somehow. Energy doesn’t come from magnets. They are simply a tool that allows you to convert other forms of energy to electric current. They are a kind of dedicated wrench that allows you to grab electrons: you, or something else, has to provide the energy to work the wrench: burning coal or oil, nuclear powered steam, windmills, or waterfalls, something, has to be at work changing the magnetic fields.
Since the fields of permanent magnets are static (macroscopically speaking) they are, likewise, useless as sources of mechanical power, which is derived from change.

In all cases, too, where an inventor thinks he is on the brink of a new machine that generates more power than it consumes: beware a flywheel or pendulum effect. A lot of these machines run for a while then stop because all they are is complex, obfuscated flywheels or pendulums. They are running on the energy used to get them ‘started’. This is the most likely scenario in machines that are started with a battery, or a good crank, and sit there and run for an awfully long time, but cannot be used to do any work, because they stop very quickly when pressed into service.
Hope this helps.
