Air Lift Technology for small recirculating systems?

For those that attended the Aquaponics Association Conference in Denver, they most likely spent time around the table Glenn Martinez and Natalie Diaz-Cash from Olomana Gardens had going. Their versions of burper pumps for demo were a big draw. I have a video of a tour at their farm on Oahu, Hawaii online at http://www.youtube.com/watch?v=-L0jeBy6GZs&sns=sms. Glenn goes into more on his pumps.

This whole topic got me thing what about an S-Educator Pump.  We used to use them in the Navy to drain wells, damaged ships.  The principal uses water to discharge water, in massive volumes.  Of course probably send some fish a flying, but the principal seems the same.  I added a diagram of one.

It allows a low pressure stream to create a high volume stream.  We have used 7lbs of water pressure to generate 100lbs of water pressure.  Why couldn't air or a combined lv delivery pump of air and water.  Just need to scale it down.

I love the idea of the air lift. Sort of feels like getting something for nothing. Especially when the low energy and extra aeration are figured in.
I believe Glenn talked about the use of air injected into the pump flow to assist the pump. I'm not sure what the flow and pressure differences work out to. I know he added a plastic drum and was able to get some decent pressure to use a hose.
