What about Zoltans? They look to be made of pure energy, yet they breathe too.

How would they expel the heat efficiently in both atmospheres and in vacuum? (wasn't the premise that they couldn't expel the heat from any refriggeration/heat exchange system?)

why did I mention watercooling systems in the first post if I already made a premise that rejected them? :roll:

I think he's excluding the idea for vacuum now. I believe what he was pushing at is that if it was simply a matter of cooling, it wouldn't matter whether it was oxygen or some other type of air, hence if just your O2 system got knocked offline, it wouldn't really matter. That's why he says the cooling explanation doesn't make sense.

ah you mean when there's no breach or open airlock? I assumed that without air circulation the rooms that still has atmosphere would be turned into saunas and heat up to dangerous levels. I mean if you heat exchange into a closed system that system is going to become hotter and hotter over time. ;)

I thought he was talking about dry ice since he mentioned refrigeration.

A race with immunity to asphyxion would be OP.

I was kind of meaning in-universe reasons, not gameplay-wise. I think we were all thinking that, too.

hmm, because rooms go red without O2 system in the very same way as with opened airlocks - we can assume that the ship isn't really fully airtight and is constantly venting atmosphere at a small rate. Generator just keeps refilling the atmosphere at higher rate than hull can lose.

Expanding on the original post, I'm wondering why the Engi (and all the other types of crew) aren't vulnerable to hyperoxia, considering that they're exposed to nearly 100% oxygen for the duration they're on a ship...

Not to mention that an oxygen rich environment is bound to be begging for fires to happen.

Maybe the percentage is the oxygen levels required to live?

Noone said the oxygen counter shows total amount of oxygen in the air - it's more reasonable for it to show the percentage of nominal level of oxygen.
So to have pure oxygen atmosphere on board, indicator would have to dial about 500% of nominal level.

(as a side note - pure oxygen atmosphere is easily tolerable by humans - as long as the atmosphere pressure is reduced. For short periods of time, even normal-pressure pure oxygen is well tolerated, as was in case of Mercury, Gemini and Apollo 1.
OFC, that WAS an accident waiting to happen and it did happened: http://en.wikipedia.org/wiki/Apollo_1#P ... atmosphere

"US spacesuits have been pressurized at (...) 30% earth sea level pressure, but (...) the gas in the suit is 100 percent oxygen instead of 20 percent")
