I have an artesian well that overflows year round a constant 25 gpm. The well is 135 feet above my proposed house site, which is 1300 feet away. Using an appropriate energy equation (head x flow x 0.18 x 0.30) I get 182.35 k. The location of the turbine to the batteries (assuming the batteries are adjacent to the house site) is about 200 feet.

What size piping and product would readers recommend?

Has anyone else generated power from an artesian well?

Thanks,

Steve:

You are not clear with the placement of the turbine in reference to the artesian out flow ( to determine the lentgh of the pipe) to define the pipe diameter for not more than 5% head loss.

I use metric since I have 10 fingers and not 8.

Water = 25( 3.78/ 60)= 1.57 l/s

Head 135 *0.3048 = 41 meters

Gravity 9.81

Gross Power watts = 1.57 * 41 * 9.81 = 630 Gross watts, expect around 320 watts

inch pipe will give you the best arrangement, about 1.2 psi or 2.67 feet head loss.
Inch pipe , will give you 9.2 feet head loss or 8.3 psi.

Cost wise 2 inch and go for it.

Head ( 135 - 8.3) * 0.3048 = 38.3 m

and gross output power 630 * 38.3/ 41 = 588 watts and around 290 - 300 watts for a total of 7 KWH / day.

A very easy to do would be a Turgo Turbine attached to a 2 HP Induction motor with biasing capacitors and transformers to bring the power down to the battery bank voltage.

www.h-hydro.com has low cost stainless steel turgos.

If you go this route I have a drawing for the casing ir such is desired.

Most people in the US have 8 fingers and two thumbs

STILL 10 FINGERS

Gosh, I only have 4 fingers and one thumb. Maybe if I didn't use the other

hand to count with, I could come up with some more!

Nando,

Thank you for your reply.

The penstock will be 1300 feet to the turbine with a head of 135 feet and a flow of 25 gpm.

If I was to purchase from a supplier (as I am not crafty enough to build something) who would you recommend?

Thanks,

steve

Steve,

I have no personal experience with hydro, but I can't help but wonder about whether water or electricity may be transported at lower cost and lower loss. In other words, are you better off piping the water all 1300 feet, or shortening the pipes and running electric wires for the saved distance? Especially if you generate a high voltage (to reduce current/loss and use smaller wires) and then regulate down at your batteries using a fairly-efficient switching regulator?

Don't forget that you can put the hydro-turbine below your house elevation and pick up extra head. The electrons from the generator aren't fussed by running uphill. I would put the turbine at the lowest point feasible.

Ok Wooferhound, that was funny.

My 14 years old son is asking:

Say kind 01 is "Know binary" and 10 are "don't know binary". Does kind 11 are the one that know that they don't know.

"Don't forget that you can put the hydro-turbine below your house elevation and pick up extra head. The electrons from the generator aren't fussed by running uphill."

There is a red spot on my forehead where I just smacked it, I can't believe I never thought of that before...so simple, but major improvement! I'm thinking about a home-made Pelton wheel made from a 4-wheel-drive front spindle brake disc. Robust, cheap, and easily able to handle 1,000 RPM. -Ron

Heres another one for you:

Oh, and the way you say it, there are 10 kinds of people. (Unless there is an extra hidden sub-species of some kind that sometimes reads binary and sometimes doesn't)

I think it's supposed to be a continuation of the joke. It implies that the writer is a member of the set that DOESN'T understand binary, and has it confused with unary (where you put down as many "1"s as the integer value you're representing.)

And there are 10 kinds of people that understand binary. . . those who do and those who don't!

Of why we should request [or demand] that folks keep comments topical. Courtesy would dictate it be so but none of us seem to have that respect.

Maybe its time to make it policy. It has been getting worse lately.

Hi Steve. Check out the Harris. With the flow i would go with a 2 nozzel.

Man, you want to stifle all creativity?

TomW · « **Reply #19 on:** July 14, 2007, 11:41:42 AM »

Ha, not at all, but I would like to encourage courtesy of keeping at least semi topical. Running on about binary numbers due to a .sig line has no bearing on the thread. Neither do my comments, either of course.

If I were truly as bad as some think I would not let such comments remain.

I think the bottom line is that regardless of what I say you will take the opposite stance so arguing it is pointless and further diverts the thread. Pop over to IRC and we can discuss it like men face to face or as close to it as online can provide. I am always open to ideas to improve things here but generally powerless to implement real changes.

If I can't be honest then I don't want to play.

I just thought it was time to pull your chain a bit. I do sympathize with your point of view. There are times when a new thread should be started, but some of the comments, my own included, do not deserve a thread of their own. Generally, I simply ignore those parts of a thread that do not interest me, such as that gun bit that showed up lately. The amount of bandwidth that text uses is small, so it's pretty much harmless when a thread is hijacked, in my view. Anyway, guilty as charged. Sometimes you can't resist. Oh yeah, you'll only find me here. I could get on my soap box and rant or argue for hours, but I try to keep that to a minimum.
