Re: Need advice on a small water-powered electrical system? I certainly hope you meant feet and not inches for your stream measurements. |

No, the inches are an accurate guesstimate. We are hoping that the supply trough/pipe fall rate in combination with gearing of the alternator drive will be enough to supply the force needed. |

OT - Nice country down there. Used to have a relative that lived in Hickory and I traveled a bit there.

It's all about power (energy/time), not force.
If the water doesn't have enough energy then no gearing will help.
You need to supply X watts of mechanical power to the alternator, plain and simple. |

We have not done any flow tests as of yet, I guess that would be priority at this stage. I will see what we can come up with. Thanks everyone for all the info so far. |

Would it be possible to dam the stream and form a small lake?
Do you know the source of the stream?

The stream has not run dry to my knowledge, a small dam could be made but nothing large...it is a spring-fed stream.

| Not to discourage you but when we purchased our property had visions harnessing our small stream for hydro power.
Looked great in the spring after snow melt but by August it slowed down to a trickle.
As cowboyro  posted it is all about flow rate and head. Need a fair amount of both to make the project worthwhile.
In NC at least you don't have to worry about the stream freezing in winter.
