O2 Concentrator instead of O2 tank

You would not net any additional oxygen from the concentrator...



Think of the concentrator as a splitter.. it sends the nitrogen down one
tube (a waste port).. and the remaining oxygen down the supply port to
the pilot/patient/person whatever.

You arent creating anything new, or creating mass.... (so no physical
laws are broken)

but you ARE directing a stream of concentrated, nearly pure oxygen down
a supply tube at flow rates of up to 3-4 liters per minute.

you ARE increasing the overall inspired fraction of oxygen to the person
who inhales this gas stream. The oxygen doesnt know and doesnt carehow
it got there. Doesnt matter if its concentrated from an ambient air
source at near ambient pressure (conentrator)..... or if its
cryodistilled, vaporized, compressed to 2200 psi, then stored, shipped,
reduced to 25-50 psi working pressure before its returned to near
ambient pressure (tank).
