When you switch a kettle off it doesn't stay boiling for very long does
it.

No reason why it should - if you only boil enough for your immediate
needs.

That can't be done

Even sillier than you usually manage.

you need to biol more water as it evaporrates as it boils

Not enough to matter and you just put in the amount that leaves
you with what you need when you pour it into the cup etc.

and any steam coning out reduces efficiency,

Not by enough to matter.

and yuo get bits of lime scale in yuor cup
if yuo use every ml of water you boil.

Not if you aren't in a hard water environment.

Ideally you'd use one of those boiling water taps

Those lose some by evaporation too.

then no one would need a kettle would they,

I personally use the microwave but
they aren't as efficient as most kettles.

but I don't believe those taps are as efficient as a kettle anyway.

Corse they aren't, because they have to keep the water hot
for when you turn on the tap and so lose some heat that way.
