Hospitals always (?) have standby alternators, but what about, for

at all now? :-)

Do you seriously believe that any sensible person would arrange things
so that their very life depended on the mains power not failing over a
protracted time? *If so, perhaps they are more eligible for the
"Darwin award" than the people in question.

All electrically operated life-support machines invariably have an
alternate power source that will switch in automatically in the event
of a mains failure.

Dream on!

Bill the emphasis is on "electrically operated life-support machines". Maybe
not in your home but in hospitals, .. yes. At Sea as well. I have been very
heavily involved in the Marine Electrical Design business and I know that
the "Back up"" power supply is paramount. Not talking of the fun yachts
swanking around the Med chasing the sun and flashing boobs here and there,
but real maritime stuff.

But the real problem is that these people DO NOT take the generators
they take cable.
If the cable is missing your generators are useless.

or think of it this way you have a fridge freezer and a geezer comes
in cuts off teh plug,
and takes teh cable from your freezer, so all you have left is your
freezer and a 3 pin plug,
how will a generator restore power to the freezer, this is the problem
when they remove
cable from track, having another gernertor doesn;t solve the problem
of someone removing
100s of feet of copper.
Of course if the cable is live then ther's a chance that person
remopving it might get killed leaving the cable in place.
