    I suppose since compost is later turned into fertilizer, composting is a bit less truly wasteful than throwing uneaten food into the "regular" trash, but I doubt that distinction is meaningful since in either case the food is no longer edible.

    The only "meaning" it has is to their particular recycling and waste disposal programs. As you say, this is not about waste at all. It is only about where to put different kinds of trash.

    If radiation enters the boundary and goes right back out, we need to account for it entering and exiting. That's why there are separate terms for "power in" and "power out".

    Just no. If radiation goes in and comes right back out, we do not need to account for it, because then the NET amount of that particular radiation crossing your boundary is ZERO. A = A. You do know how to add and subtract, right? You know what a zero is, right?

    There is no net "radiative power in" from cooler to hotter. It's against the second law of thermodynamics, and it violates the S-B radiation law: (e * s) * (Ta^4 - Tb^4).

    That's exactly the equation Jane should be using to calculate electrical heating power! It has separate terms for "power in" and "power out" so it can describe power entering and exiting a boundary. If Jane would use that equation, he'd honestly be only saying there is no net "radiative power in" from cooler to hotter.

    Just no. This is a ridiculous assertion. The equation above is for heat transfer, not radiative power.

    I used the proper equation for radiative power, which at steady-state doesn't depend on other bodies. So there is no "difference" term. Just temperature. That's simple physics. You are trying to use a heat transfer equation to calculate power out of a single body at known temperature. That's just plain WRONG.

    So Jane refuses to retract his absurd claim [slashdot.org] that view factors vary as the radius ratio, which violates conservation of energy. A cynic might have expected as much, given how Jane flagrantly violates conservation of energy by incoherently ignoring radiative power passing in through a boundary around the heat source.

    I made no such claim, you liar. As you well know, the view factor from the surface of the inner sphere to the inner surface of the outer sphere is 1. The calculated view factor from the outer sphere to the inner was 0.9998. BUT, since all the radiation going IN which strikes the hotter body is effectively reflected or scattered, it goes right back out, AND the small amount of radiation from the cooler body that misses the inner sphere ALSO goes right back out, then the EFFECTIVE view factors in this case are both 1.

    All the radiation going IN from the cooler body just goes right back OUT again, making the NET radiation crossing your boundary from the cooler body zero. If that were not so, then you'd have net energy being transferred from a cooler body to a hotter one, which is a violation of the second law of thermodynamics. As I've explained to you many times now. You're just plain wrong.

    Jane's campaign of educating ignorant, stupid physicists about physics has only just begun. Jane still needs to educate Prof. Brown [slashdot.org] and Lonny Eachus still needs to educate Dr. Joel Shore [rit.edu].

    Apparently you did not read what I wrote:

    NO!!! This is just plain bullshit. I do NOT object to a term for electrical power. I simply asserted a physical truth: in our isolated system, the electrical power to the heat source, called for by Spencer, has zero dependency on the chamber walls.

    What I object to is your insane insistence that the electrical power to the heat source requires a term for the chamber walls. This is sheer nonsense. Standard, textbook physics says the thermodynamic temperature of the heat source, since it is "the hottest thing in the room", as it were, is independent of radiation from the chamber walls. Since it cannot absorb net radiative power from the chamber walls, any electrical power calculation is similarly independent.

    You are attempting to add a term to "account for" radiation from the cooler chamber walls, but no such accounting is necessary according to the Stefan-Boltzmann radiation law. No net radiative power from the chamber walls is absorbed by the heat source. The chamber wall do not somehow magically cause it to output either less or more radiative power, therefore the input power is not dependent on the chamber walls. QED. I've explained this (truly) about 10 times now.

    Ranting about imaginary violations of the Stefan-Boltzmann law won't help Jane understand physics. It might help Jane to draw a boundary around the heat source and think carefully about exactly why Jane keeps ignoring the heat radiated in from the chamber wells. Accounting for that radiation doesn't "violate the Stefan-Boltzmann law" but ignoring it violates conservation of energy.

    There is nothing imaginary about it. I am the one who told YOU to draw your boundary around your heat source. According to the Stefan-Boltzmann radiation law, no NET RADIATIVE POWER is absorbed by the heat source from the chamber walls, and the chamber walls do not affect its radiative power out. I capitalized different words this time in a (probably vain) attempt to get you to understand what is being said here. YOU are apparently imagining some kind of magical net energy flow from less thermodynamically energetic to more thermodynamically energetic, which is a violation of the second law of thermodynamics. The chamber walls neither transfer any of their net radiative power to the heat source, nor do they cause the net radiative power of the heat source to be any less. They have NO EFFECT. Net energy flows only FROM the heat source to the walls, and the temperature of the walls effects heat transfer only, not radiative power of the heat source.

    For about 100 times now, I do not claim "no radiation" is absorbed. Just no net radiative power.

    Jane/Lonny Eachus can capitalize "NET" all he wants, but it doesn't change the fact that Jane's equation assumes warmer objects absorb no radiation from colder objects. Here's an equation which only says there's no NET radiative power input from cooler objects:

    electrical power per square meter = (s)*(e)*(Ta^4 - Tb^4)

    The above equation satisfies conservation of energy and says there's no NET radiative power input from cooler objects.

    Right. Exactly. That's the Stefan-Boltzmann radiation law, as I've stated many, many times now. Note that it is an equation for heat transfer.

    But Jane's equation is different:

    electrical power per square meter = (s)*(e)*Ta^4

    YES!!! This is a different equation! It's not an equation for heat transfer! It's the Stefan-Botlzmann RELATION between radiative power out and temperature for gray bodies. It is used for calculating
