Why overunity MUST be difficult or even impossible to replicate.

Another simple means to harvest energy from the sun light is Stirling Engine; some sources say, it's much more efficient over solar panels.

Somebody does not need to invent a device.It was done many times in the past. We have already one big wheel available for everyone... Wheelwork of nature ;-)  We only need to persuade all people to stop stupid wars and concentrate on really important topics.

What is possible does not always make something better, sometimes it makes it worse.

Dark energy violate first law (Universe expanding) and that energy keep it's density the same (constant) ...
Oh no we are going to perish in a hellish fire because if the first law violated we are going to have an energy overload 
Aside that I agree that finding OU will be difficult and will be tapering into an "unknown energy source" if we discover one, but that doesn't mean this energy source is limited (like dark energy).

Well golly jeepers,, the Universe is expanding at an increasing rate,, is that not run away creation.

and that would be energy.

The definition of the Universe to me is "everything in existence".

I think it is a stretch to say that the Universe is being "added to" from nowhere. All that is, is already contained in the Universe
by definition. The Universe expanding if it is is nothing more than a similar effect to a bullet when fired from a gun, the bang
goes off but the bullet accelerates up to it terminal velocity, the bullet does not instantly go fro rest to terminal velocity it must
gain velocity at a given rate, and that rate changes throughout the course of the projectiles flight.

Same with the Universe, the big bang was not the creation of everything from nothing, it was simply the beginning of another
cycle, everything in the Universe at some stage contracts to a dense point of mass, then it goes "Bang" and it all expands at
an accelerating rate for a certain period before it slows down then contracts again.

It can be the only way. Everything that exists now and will forever is contained within the Universe. The Universe expands and
contracts and at some point will be expanding at an accelerating rate and at another point it will be contracting at an
accelerating rate.

Surely we can all agree that "something" cannot come from "nothing".

Time is a mental construct to make sense of the passing of events, there is no end to "time" or the Universe and there was no
beginning to "time" or no beginning to the Universe, after all if it began where did it come from.

Simple answer is that all that is is the Universe and all that is is all that has ever been, things just change.
