I try to keep my self appraised of the current news in the field.
I can not say I fully understand it, and thus the questions I am about
to ask.

Question #1
--------------
If you have 21 entangled atoms, and one was separated for x distance
and then used for data transference, would the data transferred to the
other 20 atoms affect or apply to them equally (if any)? and if so, in
what ways and forms and types could this energy be transferred or
altered into? for it would seem to me that if one affects 20, then the
same would hold true for 1 for 1000.
for even though they them selves have the same energy as the one and
could only transfer the same, the others by shear numbers would
affectively generate much more energy.

a single ant may not be able to move a large leaf, but many of them
together can.


New forms of abundant energy, and if possible, negating the need for
copper wire or electric lines, or perhaps even car batteries, with
direct wireless transference.

Just a thought.

----------------------

Question #2

At some point in the history of the universe, it seems to me the
conditions for entanglement would have been naturally achieved. and if
so then therefore it would seem to me that we would or could find
naturally entangled atoms and the like, perhaps out in space or flying
through the universe. if such could be found then wouldn't it seem
plausible to use what's found to spy on what's happening in the other
parts of our universe? perhaps as seen through a type of entanglement
degeneration?

#1 NO, multiple particle entanglement does not work this way. There are perhaps thousands/millions of permutations. Even 3 is complicated. The 2 case is more straightforward.

#2 We don't know if we are entangled or not. However, decoherence theory suggests that residual effects would be minimal after a relatively short time on a planet (interacting with other matter).

the law of conservation of mass-energy still holds so even if we kept transferring the quanta (of energy) among photons/electrons it would still remain the same and not multiply (not "generate much for energy").

Quantum Entanglement: Questions

can anti-matter be entangled?
---
In the regions of where we suspect dark-matter resides (cold-space), could a lasting entanglement occur?

What do you mean by "entangled" here? As long as you can keep antimatter far enough away from matter (which is not an easy task in our matter-dominated environment), it behaves pretty much like matter (thanks to the CPT theorem). So you can, in principle, produce entangled states with antiparticles as with particles.
