Updated parametric study of orbital fuel depot atmospheric gas collector designs, notably PROFAC. Some of the study decisions I take issue with, but the results are useful. Generally, unless serious tricks are involved, particularly power density, air scoopers aren't happening. Good match for beamed power applications, and there might be room for tethered scoop trawler designs that get more of the power system mass in lower drag higher orbits.

Apparently they have a good high temperature steam electrolysis SOEC that can produce hydrogen at decent efficiencies, for feeding into a RWGS conversion reactor syngas production rig, to eventually produce synthetic methane (combining syngas from the reactor with additional H2 from the SOEC), or eventually via FT, synthetic liquid fuels. They don't seem to be doing a coelectrolysis SOEC to crack steam and CO2 simultaneously in the same cell stack though.

Scooping atmospheric air (PROFAC revisited)

Hrm, PHARO variant resembling a ramscoop connected to a solar array kite joined together via an electrodynamic tether, to possibly eliminate the MHD ramjet for propulsion and increase solar array size? It would also keep the large solar array out of the high drag regime. You could even go for an inflatable solar array. Though vehicle dynamics gets ugly, and now you are dragging around two and half objects through crowded airspace.

PHARO is the electric version of the PROFAC ramscoop atmospheric propellant collector/diver, using concentrated reflected light from SPS' dumping on a passive cooled solar cell array at (?5x-50x?) solar intensity for roughly 175KW to power an MHD ramjet thruster running on collected liquid air/nitrogen. Quick and sleazy mods I can think of are using ground based laser beamed power (rather than simple SPS reflected concentrated solar), inflatable frustum collector nozzle expansion, and perhaps a VASIMR engine (though the MHD ramjet in principle is similar to a VASIMR, with fuel coming live from the collector).

PROFAC is the nuclear thermal atmospheric propellant ramdiver, PHARO is the electric MHD engine version (ostensibly powered by 5x concentrated solar power beamed from an SPS constellation). It actually makes sense, especially if you have an offboard power source (PHARO was looking at a 200KW range power receiver). Easy mod is an inflatable frustum over the collector cone to increase the size of the of the capture inlet.
