Can someone please direct me to some plans for a small homemade water
turbine generator.
Not totally off topic because it is part of a solar school project to pump
water uphill via PV pump, then release the water later to produce some
instant power. The upper water tank is essentially the storage battery.
Thanks,
Gary

What is "small" ? Have you any idea about the rate of power you want to
create?

The amount of power isn't essential. It might be about a 8 litres of water
draining from a tank through a 5 or 10 mm tube.

Gary,
Just a suggestion... get one of those small permanent magnet motors used
in
battery powered toys, go to a model shop or simillar and get a model boat
prop
and put it on the shaft. Then direct the outflow from the tube against the
prop.
I would think you could scale down almost everything except the water
"head"...
the more height you have, the better the pressure... then you could measure
the
voltage output of the motor, or hook it to some miniature (model railroad)
lightbulbs in a dollhouse or something.
As for pumping uphill... they have little battery-powered pumps in those
tabletop waterfall things...

The Feb/March 2004 issue of "Home Power" has an article on small hydro
turbines with some good pictures.

One suggestion. Use a larger diameter tube with a 'nozzle' on the end. If
you use just a straight piece of tubing, the 'head' will be dissipated along
the entire length of the tubing. That's not what you want. You want the
'head' to be converted (as much as possible) to kinetic energy right where
the water impacts the 'turbine'. Less friction losses in the tubing means a
higher amount of head available to convert to kinetic energy at the nozzle.
