So to be clear their “200 kW VASIMR” is actually two 100 kW units strapped together… my notional version was a single engine operating at 200 kW…

…5 newtons at 5000 seconds would be great 🙂 …

… argon as both coolant and propellant simplifies the plumbing but we’re still going to need an additional radiator edge-on to the sun at -157 c and a liquifaction plant to compress, cold-soak, and expand the used argon in a classic refrigeration cycle… which takes more power which needs more cooling and thus more radiator mass..

… so can we keep the magnetic cores somehow insulated and running at -185 C while we pump up the engines to 300 C? Theoretically possible but the power cost would go through the roof…

… have we forgotten something…?
