Hi,
I couldn't and still can't find the original post, but we seem to agree with
each other in that they absolutely have to be in phase.
My point was also that machines connected to the grid will not behave like
the above situation and will lock automatically, so long as they don't
explode first.

Are you sure you are right? Run an amplifier in bridge mode and you
basically have 2 electonic generators connected in antiphase and you
will get lots of power without one side trying to catch up with the
other.

Hi,
Yes, that's true, BUT: a bridge amplifier uses two antiphase supplies,
one on each side of the load circuit. The output voltage will be
twice the output voltage of one of the "half-amplifiers". The
original poster asked about outputting 110V from two 110V supplies,
so I assume (s)he wanted the supplies to be in parallel (i.e. grounds
both on one side of the load, hots both on the other side). This is
basically like taking an amplifier in bridge mode and connecting a
zero ohm "speaker" to it. You'd better be in phase!
