"The key insight is to use electric motors to drive a compressor"
Uhhhh what? This just does not seem like a good approach, admittedly most of my aerospace knowledge comes from KSP and Scott Manley videos, but the atmosphere thins out pretty damn quick and if they're saying that they can get a benefit on a first stage by getting their oxidizer from atmo in exchange for a bunch of hardware and batteries color me extremely skeptical. This is a field that has had it's problems attacked by a lot of very smart people and the even if this made sense (to my amateur eye it doesn't) the devil is in the details.

Hope I'm wrong though!
