Two generators back-to-back, one operating as a motor and one as a
generator, with set of gears between them.  This method only works with
three-phase.  They had one at the college I went to.

God, merkian domestic electrical wiring is appalling.  No such thing as a
ring main, every socket is a spur from the distribution board - so dozens

it.  And as for the earthing systems....
