BUT efficiency is actually 100%. As we can see when we build a heat engine where a black hole serves as a heat sink. This engine has 99.9999999 efficiency, or 99.999999999999999999999 with bigger and colder black hole.
When energy goes downhill in an electric power line on a hill side, voltage and amperage increase.

No Jartza, I'm not sure how it will express itself but I don't see it as impossible, you need to have really high energies for it to be noticeable I think. And the same arguments as we use for describing 'frames of reference' should be applicable. But you have a really nice argument there. And what I think it is about is. "What the he* is energy"?
You are climbing up the stairs - you are not doing work.You are climbing up the stairs carrying a box of photons - you are doing work.A box of photons is tumbling down the stairs - photons are doing work. (making noise is the work they do)
