and boy was he right.  (apologies to many for not re-emphasizing the
subject: line in the message text, 50Hz is the goal)

Some UPS-like equipment will do this - stuff designed for running
computer equipment in a field in the middle of nowhere, normally for
pseudo military use; take any Generator input (which can be 30Hz-70Hz),
any input voltage, normally close to sawtooth or triangle wave and
covered with crap and artefacts, turn it into DC, put it into a few
lead-acid batteries, and then work with the back-end of a conventional
UPS.

yup,  that seems to be the general approach.  i have leads on a 220/50
ups of this type, and plan to feed it 220/60.  but, as you say, feeding
it 110/60 might work.
