I've seen all kinds of theories is it possible and has anyone accomplished it if it is...?

No. The laws of physics say you can't get something for nothing.
Perpetual motion refers to a condition in which an object continues to move indefinitely without being driven by an external source of energy.
The term is commonly used to refer to machines which display this phenomenon. In the macroscopic world, perpetual motion is not generally considered to be possible. Perpetual motion machines (the Latin term perpetuum mobile is not uncommon) are a class of hypothetical machines which would produce useful energy in a way which would violate the established laws of physics. No genuine perpetual motion machine currently exists, and according to certain fundamental laws in physics they cannot exist. Specifically, perpetual motion machines would violate either the first or second laws of thermodynamics. Perpetual motion machines are divided into two subcategories (some physicists, including the noted professor of thermodynamics Mark W. Zemansky, include a third), defined by which law of thermodynamics would have to be broken in order for the device to be a true perpetual motion machine.

Lisa Simpson made one but the damn thing just kept getting faster.
The only thing perpetual about the perpetual motion machine theory is that dumb people perpetually believe that such a thing could be possible. use your brain for goodness sake.

No, not possible. Not if you consider ALL inputs...even nuclear power generation is consuming matter, and the total USEABLE energy is less than the energy equivalent of what was consumed.

Well, If its true that a photon has no mass, then according to E=Mc 2 --no mass no energy--
So all those trillions of photons charging my calculator is a perpeptual machine.

Lots of people claim to have, None have proven it; none have been able to put it into a product.
Our current view of physics is that no physical process can even approach 100% efficiency, much less exceed it.

research string theory. everything is energy when you see interaction of strings you see matter or you see many forms of changing energy levels but in essence the fix point of energy never really changed, you just perceived one of its oscillating frequency points

that's the general idea of a nuclear reactor
