comment What is the secret of this perpetual motion machine with neodimimum magnets?
In the last part of the video, the device makes numerous number of cycles and shows no any (apparent) slow down, although friction in the lifting mechanism should be big. I can't imagine both of you sources provide enough energy.

comment What is the probability of quantum tunneling occurring in this CPU?
I think for tunneling to be observable, the device must be cooled to very low temperatures, like liquid Helium temperatures. At room temperature or at CPU heated temperature, one can't see tunneling in the loud noise of heat movement. Electrons are jumping physically as kicked but thermal movement.

Not everybody can control LHC. It is normal to try to interpret LHC results from the side, without using handsaw.

@CuriousOne don't consider jurisprudence, the question is physical

Okay, may be you are right. Anyway, I didn't think about initial energy from lifted weight. Simultaneously, it seems to me, that it is not sufficient source...

@CuriousOne so you think this is the trick, i.e. there is some hidden energy source?

Doesn't this energy return back once per cycle?

Why black holes can't erase information at the cost of heat?

comment How can Maxwell's Demon erase information while a black hole can not?
If heating transfers information by definition, then what was the problem with Hawking radiation previously? Object falling into black hole just evaporates into Hawking radiation and this would sufficient to solve information paradox!

comment How can Maxwell's Demon erase information while a black hole can not?
I don't understand, how the requirement to heat demon implies that he can't erase an information. From my point of view, he can freely reset his state, but just heat. Okay, let it heat. Heating will conserve thermodynamics, but violate information conservation.

comment How can Maxwell's Demon erase information while a black hole can not?
I disagree with "thus" in (3). Demons can't exist, but not because erasing is impossible. They can't exist because erasing information cause heating. Heating makes demon's work useless, but these useless demons CAN exist and CAN erase information.
