Well, the generator only gives about 55/s, which isn't enough to cover the drills and the converter, but is enough to deal with the power need during flight. I could use a few PB-NUK's but meh, it's pretty much just a scaled up version of those anyway. The setup works and it can get from Minmus, dock, and return without needing to refuel at the station, and not nessessarily needing to only go to equatorial deposits, then refuel while drilling.
