Hello I am new on here. I have been doing some research on pelton wheels but there are some questions that I havent been able to find answers for. Is it possible to build a wheel with a motor (generator) attached to it if you dont know how much head you have to work with? What RPM do they work best at?

The reason I ask is I am a college student and I eventually plan on living off the grid once I get a house built.

I also plan on having a small machine shop. Is it possible to put a 3-phase motor on a water wheel? I plan to make it an overshot wheel with a cup size paddle on the wheel. How many CFM are required to do something like this? Is this the type of wheel I should use? Should I use a water wheel?

anything will help, I am just starting the thought process and trying to figure out how to do everything.

Thanks for the help

Dont be blinded by some calculator on a web site by the figures it spits out, in reality the actual power value will be way under whats quoted in a calculator.

Its nothing more than a guide and far from a bible to follow, you must remember to add a tool (the calculator) to sell a product, the results of it will always be on the high side of a perfect situation, mind you we never have that.
