 I have this master plan, and I would like a bit of advice from you
all. I have a creek about 300 yards from the house, and in the winter
the water level is pretty good. I was trying to figure out a way to
pipe hydro power (for charging) up to the house without running copper
lines to attempt to save a few $$. Here is what I came up with.

Floating sled water wheel to run a compressor
Vain motor to run a generator (The guts of a worn Honda 1000UI
generator)
Charging system to be ran from generator

I'm really new to this design and plan stuff, so if there is a more
efficient means to transfer the power uphill, and 300 +yards without
running electrical transmission lines, please advise. I'm worried
about the ware and tear on the pneumatic machines and maintenance
expenses making it not worth while.

Every conversion creates large losses. Using an AC generator, feeding the output
into a step-up transformer, and running smaller (higher voltage) wires to the
house could minimise wire costs, but add transformer costs. Unless you are
talking large amperage, wire can't cost that much. How much power are you
talking?

so for charging batteries? Can you just move the batteries closer?

Why the aversion to running wires??
It's the simplest solution.

If the eu1000 is like the eu2000 then it has a 3-phase permanant magnet
alternator that puts out up to about 240 VAC. If you are using it to charge
batteries then I'd think you could get by running wires to your house
without too much voltage drop.

What I did with my eu2000 PMA was to rewire the alternator from Star to
Delta thus giving me lower voltage and higher amperage. I'm able to charge
my 48 volt battery bank via my OutBack MX60 charge controller at 20 amps
with the my engine barely running above idle so I'd guess that if you can
turn it with water you might be able to get enough RPMs to make it
practical. You might want to read some of the posts "z" wrote recently
about his hydro system that he's working on.

I still need to make some kind of regulator so my PMA voltage won't exceed
the 141 VDC limit of my MX60. Once I do that I should be able to speed up
my engine and get 40 amps or so. That exceeds what the eu2000 can do when
connected to the inverter which makes me think there is a substantial loss
going on there.
