Dispute for propellant usage
[edit]I'm disputing the claim that, as a matter of fact (as opposed to opinion), WAVAR is not suitable for propellant production. This use is hinted at in the citation developing the original concept, and shouldn't be dismissed out of hand in this article just because it's dismissed in the Zubrin citation.

- we know mars humidity is saturated at night, but not day. so i estimate from water partial pressure at -47 C, around 5 Pa, n=PV/RT = 2.7 mmol/m^3 or 50 mg/ m^3 might be harvested by cooling additional 20C or so. to collect 1000 tonnes of H2O to use as feedstock for propellant, you would need to process, with high yield, 2x10^10 m^3 of martian atmosphere: or 20 cubic km in about 700 days. that will be 330 m^3 per second. feasible? or not? how does it compare to zubrin's? -- Waveguy (talk) 06:22, 19 May 2022 (UTC)
