I'm going to try a funnel inside of this 3" coupling in an attempt to produce centrifugal pumping. I may need a vane of some sort to make sure the water is spinning at the maximum velocity, but I'll try it first with only surface friction.

Here is the funnel inserted in the coupling:

The idea is to self prime the turbine so I don't have to fill it up each time. I've resolved to figure out some sort of a centrifugal pump as a solution. There are a number of possible choices. I'll try the simplest ones first and and then work towards more complex configurations until I find a winner. It may take a little time but it's a basic necessity. Then we can concentrate on the fun stuff.
