Six Barrel Savonius Vawt

[muck1monkey]

Jeff seeing as you have got 3 times the amount of barrels why not go for 12 barrels . . love to see how much bracing you need for that lol

It would be nice to see final results in a video with charge controller and grid tie inverters all setup and running with tests done with multi meter to show us all

[nekbiodieselworks]

fantastic a truly genius design

[brucecohen69]

how many watts doesshe make hotel califorina escazu costa rica

[realestatenow]

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.

[yakimaborn]

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?

[dirtydogvideo]

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."

[ImaWalkerYesim]

@embeddedprogrammer How Many do volt that (vertical wind turbin) can do ( n minute if you can :D thanks)

[Behemoth2334]

What is the point of this? It's awesome but what's it for?

[alfaia]

@Behemoth2334 Free clean energy!

[planetdarwin]

this tickles my inner engineer-artist

[psychowolf666]

hello, nice idea:)

like it, does u have an simple idea of the power? like u hold it in place and how power does it want to run?

try to use two magnetic neodyme ring to support the weight of these barel, and and skateboard bearing at the top and the base an u wil nearly lose no power in friction

[Ashitaka255]

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?

[EatDrinkSmokeBeMerry]

How are you going to stop it for service? Or from keeping the rpms from getting too high?

[gabydewilde]

@EatDrinkSmokeBeMerry you hug it

[stewartpowerandlight]

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.

[bogdan1bogdan]

how much power do you get out of that? kind of noisy; but it's ok as long as it's "pet safe" :d nice work anyway.

[angurisloud]

So there's no load on this... so it's a whirly-gig right now... I'd like to see how fast it spins with the generator attached and the production data. Keep up the good work, but let us see the data

[forgiveaspie]

That's a pretty great turban.

[VantorBando]

you figure out how much energy this pumps out on any given day??

[comptonassjt]

whats the part that turns and generates power?

[eddieconnors]

Wow, Great video.

Will you take a look at my list of DIY courses at IMECOFARM com.

We have a 3 day build a wind turbine course ! Thanks Eddie

[jstsmegy]

it spin s we get it !

[haansgruber]

Making the barrels spiral in an upward fashion will redistribute the wind loading

you could also thin the barrels toward the top by sloping inward gradually to create less top end resistance

some good ideas here from readily available materials

peace :)

[drannard123]

very nice I have already watch the part one,thank you very nice ideal intelligent

[Bertziethegreat]

So, when the turbine spins, is it spinning the magnets, or the coils?

[Kdanc86]

Could you tell me what sort of turbine you would use for this sort of thing?

[shairemagrib]

Sir, can I have your contact information please, this is for overseas project thanks

[zeitgeistgreece]

amazing work you are doing!

[samdekok72]

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.

[YMSAltrincham]

Didn't think of it until I read this post, but Samdekok is right, for example in a straight 6 engine the cylinders fire 1-5-2-4-3-6. Great project though, sorta wish I lived somewhere windy now.

[embeddedprogrammer]

@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.

[boogyman62190]

i think what you are making is very clever, have you thought about making a wind generator by connecting a belt around the shaft of the turbine connecting to an alternator i realy think your design with the six drums will create great success

[padraigAZ]

@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.

[robertsulley]

Excellent, I especially like the alternating colours, surely worth a few more watts!

[dookerized]

how many of these would i need to power my whole house?

[unix001]

@dookerized it doesnt really matter how many barrels you have but more on the speed of your rotation and the design of your alternator/generator

[ScarFace9797]

@dookerized 6 of em would do you just fine but if your like the average person with a family it would take about 4 or 5 depending on how much you leave the lights on.

[KingRyltar]

what kind of wattage are you seeing with it?

[embeddedprogrammer]

Haven't hooked it up yet. I am digging a hole to permanently mount it in concrete now.

[embeddedprogrammer]

I am hoping to get in excess of a kilowatt.

[ultrakool]

@embeddedprogrammer so what could a kilowatt power? for instance, maybe a home theater system?

[KingRyltar]

@embeddedprogrammer

ah alrighty then, looking forward to hearing what its output is, when you have it done.

ty

[ghettobirdgimp]

torque monster!

[TheBillythekid2010]

Ya Know its like myjestic the way it looks and what I like about its a DIY!!! Good job and can't wait to see the power that comes from it.

[cowsaymoo2x]

thats awesome. I wish I had that much room to build something ike that.

[GunClingingPalin]

What is the RPM range on that turbine? Is there a way you can measure the RPM at different wind speeds?

[embeddedprogrammer]

RPM is about 10-250 RPM. We have a hall effect sensor but right now I am using it on a different turbine. We are looking into ways of measuring rpm by analyzing the signal from the alternator. You can see wave peaks each time a positive magnet passes a coil and divide that number by the number of magnets divided by two to get the rpm (I think). Then you don't need to put hall effect sensors and run separate wires from these turbines to measure RPM.

[mouayad888]

u gotta put a piece of plywood to separate the two pieces caus there is a risistance the air is in and out it should be in only if u know what i mean in another way there is no pressure at all to turn the turbine.

[WSBToulouse]

There is lots of future in wind towers as we see it here. One could place it next to buildings, attach it and making it less visible.

[emagnets]

Dude, That is Crazy!!.. i rated this vid at 7 stars..your own unique creation, i bet you had fun building it. cant wait to see power comming out of it.

regards

Sam

[embeddedprogrammer]

Sam, Thanks. Your comment made my day because I am a big fan of your designs. I will put out a video with power generation after I mount this in a concrete base.

Jeff

[magemaniac33]

I love you videos there so awesome xD i made a windmill because of you and it worked!

[embeddedprogrammer]

@magemaniac33 Excellent. Thanks.

[robertwgardner]

There should be enough torque there to power a real generator (as opposed to an alternator).

I'm concerned about the support lines. That may need to be steel cable.

[embeddedprogrammer]

@robertwgardner You are correct.

[field16]

Looks great. Would love to know the numbers on this one... how many watts, amps, volts... Or maybe you haven't hooked up a generator yet. Love your back yard.

[embeddedprogrammer]

I haven't hooked up a generator yet. I think I am going to have to add some roller-blade bearings in the middle because the plastic pipe is flexing and making a rubbing sound which probably is also sapping power. Then I will hook it up to power and make a mph/power graph and put it on my blog.

[field16]

OK, great then. Look forward to seeing that.

[michael970]

Looks like a great spot for wind power.great job

[embeddedprogrammer]

Thanks for your comments.
