    a question for the tech heads out there.i put up a home made vawt made out of blue barrels and it seems to be okay but i have 2 barrels on a shaft between bearings and one above it in savigion fashion at 120 degrees to each other .i reckon now the top barrel will be subjected to too much centrifugal force and will bend.would the turbine be as effective with extra barrels between the two bearings on the shaft ,either at 90 or 120 degrees to each orther .hope you get the gist of what i am tryin to ask

    I understand the question - and I have no answer... :(

    But am very intrigued - any chance you could put up a few pics? What is the turbine doing exactly?

    I have a half grasp of the question, I had to read it 4 times. It would be so much easier to read if you used proper punctuation such as capital letters, commas, spaces between words and full stops.

    sorry for being a nitpicker

    I recon that you would have less chance of the barrels bending if you put them at 90 degrees to each other.

    Would love to see some pictures too

    Jaysus, keep_going - more information again needed now... ;)

    Pumping water - how? What height?

    You'll have to explain it all now, no other way around it, now that we know it exists... ;)

    On a serioous note, I am madly interested in it, and would love to hear more on how you went about it...

    Im trying to pump it up to a tank maybe 50+ft up.yerra everything im using was in the yard bar a length of flat galv 50mm bar.i tried an old diaphram milk pump this evenin and it pumped away but only reachs just below the tank. The milk pump pumps too much water at a time and slows down the turbine.what i need is some sort of small piston pump or diaphram pump and i,m going to work it off a crank.a sprayer pump or some sort of ram with 2 one way valves

    Gear it down slightly? Pump at a slightly slower speed to take the load of the turbine.. You may have a problem in a gale that the turnine will spin it'self out of control.

    Hi OP, well done so far. I think you have 3 barrels up, 2 at one level and one on top? You are thinking maybe of trying 4 barrels all at one level, at 90 degrees?

    You should be able to gear down the milk pump by putting a bigger pulley on the pump and smaller pulley driving it. (think of the gears on a bike)

    Good windy weather for it.

    If the seat's wet, sit on yer hat, a cool head is better than a wet ar5e.
