So, as I said over on the FF jet engines thread, the standard FF setup would be
giving 15151.51 joules of net power per pinch.
At 5 Hz that would be 75,757.55 watts… 75.75 kWe is plenty to run ISS on with
ample margins for growth.
(Those huge solar arrays spend a lot of power during the “daylight” portion of
each orbit charging up some very large battery packs for the “night” portion of
each orbit)
So a test unit that could take ISS from proof-of-concept to current power levels
to 5 MWe as the tech is proven, radiators are developed, and a backup
module installed.
All without the overhead and upkeep of said same huge solar arrays, their rotating
joints, and the MMOD erosion that inevitably afflicts them.
