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.

Theory or truth?:
100' of dropping water through a 1" pipe creates enough electricity for
several people.
Water hits a disc of wood/metal/plastic and spins it to generate the
electicity?
Has anyone heard of this skill/technique?

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.
