I got an email from a very nice fellow the other day having looked at the
homebrewhydro.com (i'll paraphrase)
'Why not use a hydraulic ram pump to recover the used water from your
hydro-electric system to refill the upper pond, once it's full it should
be almost perpetual motion'.
So I thought hmm. Just how much water could I recover with the drop
left on the hill after the turbine? Found this very handy site
http://www.thefarm.org/charities/i4at/lib2/hydrpump.htm
with a nice chart giving the working drop, flow etc. Using high estimate
values I figured I could lift nearly 90 liters of water back to my pond
every 24 hours with such a pump .. and since I'm using just around 80
liters a minute I could recover an extra minute +/- of hydroelectric
output every 24 hours ..
I explained that to the fellow how much pipe and labor was involved and
how I didn't see how an extra minute of power production every 24 hours
would be worth the effort. And gave a little exposition on conservation
of energy and such ...
Undaunted, our friend informs me he will have a working design up and
running by labor day. I told him 'more power to you mate' and said I'd
await his real world findings, not being one to piss on anothers creative
fire.
Needless to say I'm waiting with baited breath. This could be it!
I'll let you know if he's cracked it.

LOL. We'll look forward to your reports. I can't imagine what you'll do with all
that power.

I'm with the great minds on that subject:
Quotation: "I have nothing but contempt for anyone who can spell a word
only one way."
Variations:
1. "You should never trust a man who has only one way to spell a
word."
2. "Pity the man who can spell a word only one way."
3. "I never met a man so narrow that he can spell a word in only one
way."
