again.

Perhaps aluminized Rayon?

And what is pictured is fine for non-flexible parts of the body, as silly as it looks. I just need something that flexes better than aluminized mylar.

No and no, neither of those are practical. The actual operating parameters are more like 125psi/350F, but I want a safety margin.

So I'm looking for a material that is capable of withstanding 450F steam, but flexible and light enough to make a jacket out of.

/sci/ got any ideas?

>>4414185
Again, I really don't see the suit getting anywhere near 125psi. The pressure of a steam line is going to drop enormously in the event of rupture, it won't just suddenly make the entire tunnel 125psi.

>>4414171
Yes, but there is a big difference between what is in the steam lines, and what a reasonable worst case for someone even close to the steam lines will see as far as pressure. You don't really hear about the blast from steam explosions injuring/killing people, it is the heat.

>>4414162
Sort of a worst case scenario for the actual steam lines.

The suit will never see anything close to that unless you sit on a steam line while it explodes.

>>4414143
Actually, this is a not so hypothetical plan to explore steam tunnels...

>>4414135
Also the suit would obviously have to either seal rather well, or else use an open circuit SCBA.

I'm attempting to design a hypothetical suit that would protect the wearer from close proximity to a steam explosion, in addition to high radiant heat for prolonged periods. The steam would be at 125psi and 350F in pipes, although in the event of direct steam exposure the pressure would have to have dropped a lot due to pipe rupture.

I'm imaging something along the lines of NOMEX coveralls and hood for conductive heat protection with an out aluminized mylar shell as a vapor barrier and radiant heat shield. The suit would have an "escape SCBA" in the event of pressurized steam exposure, which would buy the user enough time to escape from the source.

The visor would probably be something along the lines of a cellulose-acetate faceshield with regular mirror tint window film applied for low emissivity.

The general configuration would be similar to a fire prox suit (pictured)

Any more brainstorming on this?

>>4341138
Yes, are we for sure that this *is* a CO2 laser?

I also said, perhaps it is 700nm? Could that be what the 700 is?

4.0 in EE?

WHERE THE FUCK DO YOU GO TO COLLEGE?

I mean seriously, I don't think there is even a single guy in my program who has a 4.0 by junior year (I'm at a big name/high rank/cutthroat school)

Well fuck, son. I'm stocking up now.

OP's pic looks just like my calc 2 TA. He was a real hardass

I am currently writing a histogram kernel in CUDA for a 128 TeraFLOPs supercomputer.

AND FAILING FUCKING HORRIBLY AT IT.

-In terms of time (ie how many hours worth) how much breathable air can a space suit with a PLSS carry?
>8 IIRC
-Are these suits bulletproof? My research indicates that they are heavily insulated ans specially designed to avoid breakage, but can they stop bullets?
>I would highly doubt it, possibly 22LR, but that would be about it
-How strong are the glass(?) panes on the helmets? Are these bulletproof?
>Again doubt it, 22LR at most
-If broken (ie torn, broken, leakage occurs) will the wearer undergo explosive decompression?
>Sort of. It isn't really "explosive" though
-How well do conventional firearms (ie pistols, rifles) work in space?
>Perfectly
-Do the answers to the above questions change if on the moon, as opposed to in space?
>Not much

Correct on it being two different dogs.

Also here is the pubmed on RJ white's monkey head transplant: http://www.ncbi.nlm.nih.gov/pubmed/4997130

Confirmed for not fake. The scientist behind this was Dr. Demikhov (sp?) if I remember correctly.

His contemporary was Dr. RJ White, head of neurology at Case Western U for a couple decades, he "successfully" transplanted two monkey heads in the 70s.

There is still similar work going on, just look through medical journals. These experiments were basically the basis of the modern ECMO.
