I was going to tell about an alternative power discussion group I found
online. I thought it was called "Otherworld" or something, but I
couldn't find it again. There was a guy talking about using a simple
jet of compressed air to force water up (he only had 50 feet to go).
But what do you know? I not only found out what my pump's actually
called: AIR DISPLACEMENT pumps, because the air displaces the water.
But also, here's a company called Air Well Pumps that makes exactly the
same model that I'm building, with a simple water-level detector to
sense when to change the 3-way solenoid valve. This little .pdf has
really given me some helpful tips! They talk all about some
non-electronic control methods, and the problems they have.
