Yikes.
Yes, I believe it might "evolve" into many different things if people begin to dabble with it a bit.
I once built a small vertical axis wind machine that looked a bit like a pinwheel.
It consisted of four cardboard notebook binders attached to 4 horizontal arms.
Each binder had a string across the edges so that it could open no more than about 45 degrees.
When you stick it out in the wind, the wind catches and opens the binder on one side, pushing the assembly around. All binders heading into the wind are shut and offer little resistance.
Essentially, until the wind blows, there is no "wind machine", only some notebook binders sitting there on sticks. Adding some wind, each binder, in turn, opens, thus momenarily becoming a passive energy-rectifying transfer device with it's intercepted energy then being transferred to the axle shaft.
What I'm getting at is that we feel free to accept the idea of purely mechanical forces in our environment being captured through passive entrainment. Yet, we have difficulty believing that the same can be done with electrical or magnetic forces in that same environment.
There will never be any "defying" of the laws of thermodynamics.
There's no need.
The term "perpetual motion" is nonsensical and the term "over unity" should just be replaced with "C.O.P." figures. The only working machines in the known universe are those that tap energy from one source and transform it to another form, doing work.
All machine efficiencies should be rated using C.O.P. alone
(power output to user)/(user input)
Obviously it's better when those energy sources are FREE for us to use, or very close to it. I almost wish I lived next to the garbage dump, just so I could tap the methane that the city wastes on an open gas release torch.
In your minds eye, at least try to imagine a small-footprint electromagnetic device that draws a very small amount of energy from a battery. Using that small amount of power it builds a larger(than the device itself) cross-section EM "passive particle entrainment zone", drawing in a larger amount of the ambient energy and concentrating it in a storage device of some sort. The device itself would be the analog of a wind machine hub. The "collection zone" would be the analog of the blades, mounted to catch the wind, having a much large cross-section than the hub itself does. Now, imagine that the blades were set up so that it required a small battery to "unfold" them from the hub, like a flower in the sun. When you disconnect the battery, the blades just fold back into the hub.
Now you should pretty clearly understand what I'm getting at.
As with any other natural energy flow, one must only place a device of the proper design "in the way" in order to extract some of it's power.
No energy is truly "free". But, if you can passively collect it, it gets a little more "free" with each passing minute.
