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

type of things battery powered nowadays? Indeed, are such things used
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!
