Broke: RFA using German automotive parts for rocket engines
Woke: Spark using Chinese EV parts for rocket engines
I kind of thought the Rutherford electric pump cycle was a bit of a dead end that wouldn't scale, but it makes sense that efficiency gains are unlocking more performance. It would be cool to see Rocket Lab keep upgrading theirs, but they're probably too all-in on Archimedes and Neutron at this point.
