Good morning Tony;



Thank you for sharing your very complete account of these projects. I am sure
that mosst of the members are more than casually familiar with the principles
and similar applications, however it is always gratifying to hear a first person
shared account,especially

one which is so adequately annotated with photos and drawings. Thank you again,
it was a great read. David Murray, P
aris Ontario.

Doug, (the guy who wants to pump water uphill for irrigation).. this might not
be of help, but it gave me some great spin--off ideas.. check it out.....

simple..good luck .....Tony in Jamaica

Not micro-hydro-electricity, but rather a (mostly) micro-hydro-irrigation
experiment:

We want to pump water from a creek, up a steep bank (30 feet/10m vertical, 600
feet/200m horizontal) to drip irrigate the farmland above, using just the power
of a fast running creek. Unfortunately, there is almost no elevation drop, so
our first choice won't work (a self-powered hydraulic ram pump). We have no
electricity, and running a gas/diesel generator or water pump is not an option
for us, due to their expense, maintenance, and noise.

Next weekend I will be testing a propeller (not a paddle wheel), mounted on a
water pump immersed in the stream. I am expecting 5-50 litres/minute output, and
if it works as planned, I'll make available the results. If people are
interested, I'll also make up a kit of plans and parts to sell, including my
custom stainless steel prop-to-pump adapter, for those people in the same
situation as us (ie, proximal to a source of medium to fast-flowing water, but
without any appreciable elevation drop).

Lastly, any excess water not used for irrigation, will likely be run back
downhill through a very small microhydro system (yet to be chosen or designed),
to generate a few, to a few hundred watts, to continuously augment our solar
power and recharge the batteries. Inefficient, yes very, but convenient,
continuous and almost free....

Doug
