I copy you on that!

We ran the Welsh cottage on (for now) stone age hydraulic power. No mains nothing back then. We had a stream & a possible 150 feet of head pressure with 3~8 gal/min flow rate, if we wanted. I never saw the stream dry or 100% frozen.

We ran 1 1/2" pipe back about 80' & 2' up, mostly almost horizontal, to give us a 18" head & dropped it in 2 stages 45° for  a foot & a second 45° for the rest. We reduced the pipe to 1" then 1/2" as well. Used automotive electronics (Zener diodes & so on) & deep discharge big lead acid batteries for storage. Made the pelton wheel ourselves. It drove 2 generators (this was before alternators.) Charged 2X 12v banks & pulled our 24v supply.
We used RV lighting & domestic equipment as back then it was all 24v.

We had solar water pre-heating on the roof. zig-zag small bore copper pipes in black-painted shallow boxes with old scrap windows on top. Water slowly climbed it as it heated & got less dense, looped back round into a 75 Gal water heater with a busted element. It was higher than the inlet so it was self powering.

They'd be madder than wet cats if we did that here!HugCensored

We have a similar system @ the cabin. Solar electric system. Drives the lights, water pumps, TV, radio, & in summer - the fridge. (We have a propane fridge for the later part of the season). It works well. We've swapped out inverter after inverter, til we have it right. (Burnt one out by firing up the gen without locking out the inverter). We finally managed to source a "true sine wave" inverter", it works smoother.
It provides everything we need @ cabin. They wanted $10,000 to run the power to the property line..then we would have to run the line from the road to the cabin (450 meters) thru the bush @ our expense, plus maintain it. Solar was the better option. We use deep-cycle batteries. They are heavy & expensive. Last about 6 - 8 yrs.

The Coast Guard uses AGM batteries for solar systems. IIRC Sunliyte was the last brand I saw. 100 amp hour and will charge at really low amp rates. I use 4 AGM batteries running parallel into a 3000 watt true sine wave inverter with a 2200 watt generator for charging and back-up. Last outage lasted 4 days and propane fireplace, fridge, freezer and lights no problem. Turkey cooker makes a lot of hot water in a hurry.
