David: where are you located on planet earth?
I'm one who enjoys building my own anything, often with the feeling that there is a better or more efficient way to go. At this time I'm real busy working with a "different" type of battery chemistry thats proving out so far and solar PV panels, which are on hold right now while I run a K of fencing to keep my goats off the local mountain lion menu (lost 3 the last week or so).
My water flow is variable due to how wet the year and the flood control dam 5 miles up river, so will feel lucky to get a steady 1Kw from 1 cubic foot a sec. and a 2m head, hence my developing the batteries and a diversified system. I've got a left testicle I'd trade for 10Kw constant
I have learned over the years what I can live without and have lived off grid on 45 watt solar, RMH, propane fridge and running a small gas gen twice a week to watch a movie and charge up batteries and don't realy miss most of the so called modern conveinences.
Please keep us posted on your choices and progress and please post the data on that gen system so that you might get some feedback before investing?
