Your science creds are instantly dubious to me
First of all, I'm not committing the
faux pas of engaging in the logical fallacy of an
appeal to authority, so my personal credentials are irrelevant to this discussion. You don't have to take anything on my authority, or even on a singular person I cite - the concepts I discuss are pretty pedestrian high school science (biology and physics). The values I use for enthalpy, specific heat, caloric value, etc, have been derived and confirmed by numerous private and public agencies for use in scientific study and industrial processes.
You don't understand the basics of science or its practice, instead treating your favored 'experts' as holy priests - a dangerous streak of ideological authoritarianism.
f you know so much about "the fundamentals of physics and chemistry" tell me the theoretical limit (max efficiency) when it comes to outdoor burnings or indoor, whatever.
The theoretical maximum efficiency for any combustion process is a 100% total conversion from the reactants to the products. For example, a theoretical maximum efficiency (100%) for the combustion of methane would look like this: CH
4 + 2O
2 → CO
2 + 2H
2O. If you'd recall chemistry from high school, you'd remember this practice as stoichiometry, its quite useful! Naturally, this is all
theoretical, as real-world examples of any process have issues that result in left over reactants, but 100% is the
theoretical upper bound. This applies to processes like vaporization, as well, with energy as a reactant to drive the phase state change.
The fact that you thought this question was some kind of 'gotcha' or clever retort just demonstrates your lack of understanding in either chemistry or physics.
Give us some numbers. You like science so let's talk science.
I did earlier, up-thread, to which you have flip-flopped between telling me the numbers don't matter because they had magic crematoriums no one has ever seen, or used magic burn pits that require even less fuel.

"There are no bodies because they cremated them all to dust."

"Where did the fuel come from for that?"

"Well they don't need that much fuel, they had crematoriums."

"Well that doesn't seem possible and the photos you've posted seem show burn pits, not even crematoriums."

"That is because they did most of the burning outside."

"THAT REQUIRES EVEN MORE FUEL SO WHERE DID THE FUEL COME FROM?"

"Look at these guidelines for sterilization prior to burial of diseased cattle corpses using air curtain technology that wasn't developed before the war, using the kind of fuel the Germans were most desperate for at the time. That proves they would only need an impossible amount, not an incredibly impossible supply!"

"That makes no sense, besides the time-traveling technology, as now you're restricting the fuel sources even further. Which only begs the question: WHERE DID THE FUEL COME FROM?"

"They don't need much, they had fat jews to fuel specially designed magic crematoriums!"

"What? You just said they used burn pits! Now magic crematoriums? This is implausible on its face! Where's the evidence?"

"Well here is a memo from a guy who knew a guy that heard in a bar that it happened, and a patent application from after the war!"

"What? That isn't evidence, just some statements we can't verify. Show some photographs or maybe-"

"There are no photographs, all photos were banned and its ridiculous to even ask me for them! Only a Nazi would ask for a photograph of the crematoriums!

".........."

"Now let me show you a photo of an open burn pit, staffed by people with no uniforms or identifying features. That PROVES that 6 gajillion Jews were holorcoasted!"

"What? You just said that photos were banned at all these camps and asking for them would be silly!"

"Silly for you, of course! All evidence proves the Holocaust, and the lack of evidence just means you can't disprove it!"
and [you] mostly have played dumb.
Impossible, nobody does dumb better than you, Chugger.
