I need a DC supply (could be split into 5 supplies of 1/5 the current)
that will handle a continuous current of 1000A total. So, 25-50kW,
roughly. Ripple at 60Hz should be < 2%, regulation and any HF hash
isn't too important.

Any ideas for something (relatively) available/affordable?

3-phase 480V/600VAC SMPS?
MG set?
diesel?

Since regulation isn't important how about a big stack of paralleled
lead acid batteries? Star topology wiring would probably be best.

Various manufacturers like lambda power and unipower-corp
make SMPSU modules that work in parallel.
Unipower TWRI series will do 9000 watts
