I'm curious as to what was happening. Did the pump keep the tank full
because it was boiling off steam, or was the excess water overflowed for
Thinking about it, it's a shame you couldn't just run the power to the
local grid. If it was 60 Hz, all you would have to do is synch up with
the power, and feed the feeders. Or else disconnect the feeder and just
supply the local AC loads.

PUNCTUATION - Apostrophe
Incorrect uses: (i) the apostrophe must not be used with a plural
where there is no possessive sense, as in ~tea's are served here~;
(ii) there is no such word as ~her's, our's, their's, your's~.
Confusions: it's = it is or it has (not 'belonging to it'); correct
uses are ~it's here~ (= it is here); ~it's gone~ (= it has gone);
but ~the dog wagged its tail~ (no apostrophe).
