It seems there is actually quite a bit of relevant research and info out there;
it's just that
they use different, more complex terminology.
I had a simple idea yesterday which seems to me that it may allow lifting to
greater
heights: Incorporate some loops in the tube/pipe carying the water and air up.
My thought
is that this should help maintain a more effective mixture of air with the
water. (Basically
making stages or "stair steps" in the system.) Here's some relevant info I
found: http://
