you should use magnets to cut down on the noise

[embeddedprogrammer]

@stewartpowerandlight the noise is the plastic pipe rubbing against the steel pipe. I am trying to design a center bearing to stop that.

Hey Jeff, more quality work from you mate. You might want to offset the phases of the barrels differently so you don't get a wave shaped force travelling up from the bottom of the central shaft to the top with each cycle. If it is too nosiy once the gen is connected you could play around with the barrel orientation to tune a different natural frequency. _> Love your stuff.

@samdekok72 I'll check that out. The noise in the video is because it was rubbing somewhere which I am trying to figure out and fix, probably by adding another bearing half way up.

Hi, Are your DIY turbines capable of producing a decent amount of electricity or they pure experiments?

If yes, What do you think of the amount of time and money that goes into making them vs the amount of electricity produced?

fantastic a truly genius design

how many watts doesshe make hotel califorina escazu costa rica

Have you considered putting on top of the roof? That way you pick up the extra wind speed of air accelerating due to the roof slant.

what kind of energy are you expecting? What appliance could you run off of it. If nothing, whats the point?

[yakimaborn]

And exactly how much energy do you expect to get? What kind of applicance would it run?

@embeddedprogrammer . use automobile wheel bearing set up.  give you a breaking mechanism also. cheap to find in any junkyard. We did this 25 years ago with three 50 steel drums. would turn even if winds were so slow they wouldn't flap a flag.

cool turbine...and it sounds like an old steam locomotive......cool benefit. i just wonder if these would be more efficient if there was a plate blocking the ability of the wind to pass through the barrels where the 2 halves are joined together?..of course if that eliminates the steam locomotive sound....its no good!...lol

[chipsher42]

Very good comments! Noise results when air is moved. Some wind related sound is to be expected, but all other sounds in the system are the result of transfer/loss of energy; friction. You'll need "thrust bearing" to support the mass of the rotating/dynamic system. And you'll need radial control to minimize excursions from the rotating axis. Rigidity of components will lessen flexure & waste, but could hasten harmonics re: samdekok72. Very cool dude! Google: "neodymium magnets."
