water electic

If you want to produce more power, I would suggest a larger than 1" pipe to
increase your volume.

Pelton wheels work on a ratio of pressure (head or elevation) and volume
(cubic feet per second or gallons per minute) The size of the pipe will also
limit that due to friction loss of the pipe so the larger the pipe the more
potential volume. Your volume is also obviously limited by the total volume
you have available at your source.

If you have more volume you can have less head  and vise versa.

A good resource for this are renewable energy catalogs, like Real Goods,
Jade Mountain, Alternative Energy Engineering. You make have a local company
that sells these products. They can help you size your system.

What you need to figure out is how much energy do you need at any one time.

Truth, you are probably referring to a Pelton Wheel generator.
Water is forced through a small nozzle where, upon exiting the nozzle it
strikes  small cups (usually 4) that are mounted on arms on an axle that is
connected to a small generator. If you imagine a wind anemometer, you'll get
the picture.
I am away from my references sources, but I believe that you do not need
100' of head to run a pelton wheel.
Check the Real Goods catalog.
