What's efficient?
Ever heard of a "hydro-ram" ?

(ie something like that scheme has been used to pump water for
150 yrs or so, and it is efficient in terms of low maintenance)
"

Yes but.
A hydraulic ram requires a supply of flowing water. What I was
describing requires rapidly pulling fairly hard vacuum on fairly large
volume to get a column of water moving up. The difference is in where
that energy comes from to get the water moving.
Mostly what I wanted to describe was a method by which it is possible
thru the use of suction (vacuum) alone to get water to a point higher
then atmospheric pressure would normally allow.
