Subject: [microhydro] Any real potential here for AC power, guys?
There is a pond that is served by diverted stream water in a 6" pipe.
Total
head to pond water level is about 14 feet or so including a 8" drop
into pond
via waterfall. Meanwhile, pond discharge via syphon valve 10"
diameter PVC.
The water really rockets out of the discharge point and am wondering
if a
turbine could be employed at this point. My untested guess is 40 gpm
that
seems pretty constant. Is the head meaningless, with actual pressure
being
driven by pond volume and syphon physics? Is this worth pursuing or
is there
a fly in the ointment? Seems like the pond reservoir allows for good
regulation
of discharge with any variations of inflow reflected in surface level
in pond?
Problem
might lie in 10" diameter which is not "full." Could discharge be
split via Y
fitting into one 5" pressurized, enclosed pipe to turbine with any
extra flowing
through the twin "overflow" pipe?
Any advice or education for this non-techie is welcome.
Thanks,
George
Dear George,
I forget where, but somewhere on the net (that narrows it down!) I
remember seeing a family that had taken and put a boat prop on a shaft and put
it on the end of a pipe coming out of a dam. The shaft then came out of the
pipe and went about four feet to dry land where it was attached to a DC
generator. Simple, easy to build, and cheap!
I will look around when I have the time and see if I can find it. I think
it may have been on Otherpower.com.
Sincerely,
Dennis
