Once again, how bizarre. The whole reason Slayers deny that an enclosed source warms is because that implies greenhouse gases can't warm the surface:
I stipulated before we got into that discussion that we were discussing ONLY Spencer's experiment, nothing else. You agreed to that condition. And now, you're violating it by extrapolating my comments to a completely different context. Which is no surprise to me at all. And it is equally of no interest to me, except where you distort my meaning by using my words out of context.
In other words: bok bok bok BOKKKKK. That's what I thought. Jane/Lonny Eachus is chicken.
Hahahaha. I have already stated my reasons, so let's be clear: I already know the answer to the problem, and that answer is supported by multiple textooks and experts in the field. So please explain to me what possible motivation I might have to bother, much less bet, Prof. Cox about it?
As I wrote earlier, if you feel you would like to make such a bet, go ahead. If I had been "afraid" of what you would find, I would not have encouraged you to do so. I just have zero reason to do it myself.
If Jane/Lonny Eachus were a real skeptic, he'd at least consider the possibility that Jane's "radiant power output" equation doesn't describe "electrical heating power". Jane's textbooks don't say to use a "radiant power output" equation to describe "electrical heating power".
If I were a "real skeptic", I would have researched the real answer to this problem. But wait... I actually did! Unlike you, who found some equation for "electrical heating power" which applies to a space that is air-filled and subject to conduction and convection, I looked up the actual power equations for a vacuum-filled space with only radiant heat transfer.
And Prof. Cox isn't alone, not by any stretch of the imagination. For instance, Grant Petty is a professor of atmospheric science and wrote A First Course in Atmospheric Radiation. He wrote a letter:
Spencer's experiment is not "atmospheric radiation". It involves a vacuum.
The rest of your comment is similar irrelevant straw-man fluff, attempting to support your fallacy.
