... The random-type order of heat energy simply isn't enough to
produce a particular function. He mentions that heat is used
all the time in heat combustion engines, so I'm obviously wrong
to say that heat energy, by itself, is worthless when it comes
to obtaining "useful" work. The problem, obviously, is that
without the order of the engine itself, the specific arrangement
of its parts, all being there in just the right order, heat
energy added to the mix just won't do anything useful.

You're being too literal minded. All that's required for useful
work is a heat source and a cold sink.

I have to agree with Sean here.

Then you need to lie down until the feeling passes. Make sure that
you don't operate any heavy machinery.

You need things something like
pistons, valves, cams, shafts, etc. Even if you take the basic
hardware as given and claim that all of the 'information' for
extracting energy is in the cam, you still need something like two
to three bits of information in the cam to open the valves at the
right time, etc. Otherwise you don't get power out of your heat
source and cold sink.

Study a little thermodynamics before you start blathering on about
'information.'

I've done that. Now explain to me where I am wrong. Show me a heat
engine which still works if the order of the operations is changed,
or if the directionality of any "one-way-valves" is reversed. I'm
pretty sure it can't be done. The closest I've seen is the work
of Anthonie Muller on convection-driven engines for producing chemical
energy from enzymes in an abiogenesis context, yet even here, a slight
change in the specification of the enzymes would make the system
non-functional.

You do understand that the preceding paragraph is a complete non
sequitur, don't you?

Nope.
