Harness Hydro Power


Hi, everybody. Sorry that I havn't written for awhile. I started a new job and have been busy.

A friend showed me this article today and I thought I'd share with you.

I was thinking this could be made on a small scale as well. Like using 2 pvc pipes (12 inches in diam and 18 feet long standing straight up or partially buried). This would give about 200 gallons of air columns. The pressure would depend on the head of the incoming water. The water would be a stream and piped just like you are running micro hydro. In fact, you could run micro hydro just before the inlet. It would go into an eductor that sucks in air as water flows through it and into the piping. The water outlet could be elevated with another pipe or a automatically throttling valve could be set on the output. You could then use the water for irrigation, drinking, or direct back to the stream.
A schedule 40 pipe 12 inches in diameter can handle 79 psi and a schedule 80 can handle 137 psi.
Every 32 feet of water drop should give roughly 15 psi. So, typical property wouldn't see more than 30 to 45 psi. But if you bury the pipes you could add a little to that.
