Why it is repeating multiple times?

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

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!

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.

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.

If erasing information is not possible, then demons CAN exist, because they should not care about information anymore. They can't erase it, hence they won't heat, hence they can work easily.

comment Where does information go if thermodynamic death?
Still not clear for me, but the answer is probably correct.

What about thermodynamics law? The same reasoning can be applied to violate it: if I have cooled teapot, I can trace molecules movements back and reverse heat it (with the help om Maxwell Daemon, of course). I.e. collect heat back again.

How to ensure that current bulbs are not close to maximum? Your plot for 3000K shows maximum is already almost in visual range.

P.S. I expect that we should redraw spectra you posted so that the area below the curves be the same for all curves (and equal to 60 W). Theses curves drawn for the body of the same surface, while we will get smaller surfaces if we want hotter filaments.

Sorry, still want to enforce the clarity. Suppose we have access to materials of any infusiness. You mean that we can make bulb the same brightness as the Sun, for example? Just make very thin filament and we will have the Sun inside? We will be able to dry the fish and brown our bodies from single bulb? Is this really true? Isn't this very thin filament become dimmed because of it's small size? And if so, doesn't this mean that there is some limit therefore?

Suppose I have infusable material. How to make 60W filament, heating to million degrees?

P.S. Sure I agree with your definition of brightness.
