And the more changes in medium that you introduce into your system, the greater the thermal inefficiency and the greater the lost energy that you don't end up with at the far end.
The spinning discuss will lose more energy than your screw. What you want to achieve is the most amout of energy converted with the least loss of potential or latent energy from your source. (Been about 25 years since my energy conversion course) Your other problem with the spinning disc is mass flow rate of heat in from the solar source to kWh out to your electrical system.
The windmills are a good low loss choice, with a variable input.
The screw in the stream is as direct an energy transfer method as I can think of.
Except, of course, for your solar panels that use the direct change from solar to electric energy.
Sound like a combination of all three might put you in a good spot, however, cost effectively, depending on the vertical drop and hence potential energy content of the water source, I'd hazard a guess at the screw being your most cost effective solution . . . if it provides the power level you need. If you are running multiple refrigeration units, I'd have a good hard look at an optimization of fewest units and best insulation of each to keep your energy demand down.
