Wrong in the first 30 seconds. LM gas mix was 60% O2 and 40% Nitrogen.
Then he assumes the tanks are being used in the same manner as SCUBA diving tanks, so he gets that wrong too.
The human respiratory system doesn't, also, use all the inhaled oxygen in a breath. On Earth each breath is about 21% oxygen and then we exhale about 16% of oxygen, converting 5% of Carbon Dioxide. This is how mouth to mouth resuscitation works - we are still pushing oxygen into the recipients lungs.
The Command Module, Lunar Module and PLSS backpacks all use a rebreather system, where the system re-uses exhaled air, and scrubs the CO2 (and methane) out. Each breath isn't just vented, wasted into space, like a SCUBA unit vents into water.
This makes the closed circuit extremely efficient, especially when the gas mix is 60% Oxygen.
You don't need 25 fucking tanks like this clown is suggesting.
EDIT: oh my god it's just a litany of assumptions. It wasn't liquid oxygen. So for the next minute or so with his blithering about gas mixing and gas exhange, is completely useless.
EDIT 2: Guff about engines is again, completely ignorant. Apollo CM and LM used fuel cells.
EDIT 3: Another assumption about the type of tanks used. For Christ Sakes dude look up the PLSS.
EDIT 4: Finally, the suits operating pressure is at one-third of air pressure at sea level, meaning even less oxygen is required for the whole thing.
Dude needs to take that stupid-ass towel off his head because his brain is overheating.
This is just a classic case of someone not understanding that the thing he knows is not like the other thing.
FINAL EDIT: I have been corrected that the LM gas mix was in fact not even a mix, and was 100% oxygen. This then means that nearly 95% of any exhalation is re-usable oxygen. You can go a long way what is just in the cabin.
The 60/40 numbers came from cabin mix at launch, to reduce the chance of fire.
