What type of turbine is the most cost and energy efficient for a single household?
And I am wondering how I calculate how much water pressure I need to produce X watts of electric power.
How steep of an angle, and long/wide does a pipe need to be to produce X amount of force, and how much water volume does one need per second, etc.
(how do I figure out if a stream is good enough or not?)
Can someone point me in the right direction and what terms are used?
I'm no math genius, so please put it simply if you can, thanks!

Maybe this is simpler to answer, what type of system do I need to get 3000watts +, continuously?
