Well pardon me if any of you take any offense as you will note I am in no way a nazi or skin head or racial hating individual...

But here is the my other idea which I may settle for thinking on design ...

Think of a swastika with hinges more or less now imagine if when the wind blew half or more then half of one of the blades opened up...

This is possible below will be a picture of an overhead view showing what I believe will be a great vertical axis turbine design!

I would like your opinions on this design I think it will maximize energy production by reducing drag!

I am shocked at the lack of interest in power generation via wind and solar power!

They are working technology that can be replicated ...

It is not coils wound on a tinfoil hat I suppose so it does not make for good chat maybe?

I don't get it its like folks do not even want free energy they just want to talk and listen to a lot of far fetched tech...

I am sure there is other stuff out there yes I agree and you should give things a chance but in the mean time why not pitch in in these areas and build some stuff that works for free power to hold you over for the next big thing.

the hinge design is slightly flawed - it's still workable though, what you need are hydraulic brakes to keep the flap from slamming backwards and taring off the rotor, they might as well be spring drawn too, bringing them forward later in the cycle.

slaps some mags on the brakes and you could make a secondary generator - a third if your count each as a generator, it would me ac, ofcourse, you could even use the load-through-coil as the brake.

Hi Infringer,

Here is a design that uses hinges:

That should work well.

Take care,

Hi Infringer, I like your idea of the hinges design, but I think you lose too much power as the wind has to first open the panel then spin it.  I just saw this idea from greenpowerscience.com.  They have the idea to use two vert wind turbines, one on top of the other.  You have one spin one direction and the other spins the opposite direction.  Between the two, you have the "generator" part.  The magnets are on one and the stator part is on the other.  By spinning in opposite directions, you speed up the generator parts allowing you to generate more power.  I thought that was a great idea :)

Just had another idea, you can have multiple rows of magnets, stators and can multiply the power output.  Also, they are showing the use of neo magmets to support the turbines and they double as the bearings to reduce the friction from spinning.

I am shooting for the original thought I believe that will be easiest to make and in general the less complications the easier the matinence and everything...

Thanks for your input once again... I look forward to what others have to say it is reassuring to know that I am not the only guy out there thinking on a simplistic level but I am a little curious about magnet motors as well like the mylow's and so on so forth. But I know a wind turbine works so rather then waste a boatload of time and money attempting these claims and the many others I would prefer to start something that works and will pay off without a hitch well almost hehe!

The springs were an excellent idea and yes my design did have that flaw thanks for pointing that out but my rotor I believe will be axial flux based therefore I believe the only thing I will need to worry about in that case is the actual hinges no break should really be needed but the thing is no matter what it is it will wear on the bearing so you are most certainly correct!

Thanks

Hi Infringer,

I agree that the windmill is not very popular but it is mainly because of city restrictions on erecting one. I will make a vertical unit this summer probably 3 or 4 feet high so as to not offend my neighbors. I already have my axial alternator, charge controller, my inverters and batteries.

I have started to design 2 window motors but not like Bedini has done it as it is too inefficient. The way he shows to set the coil(s) is the worst you can do. The wiring schematic he post is not the one he uses (3 hall effect sensors), so we have to redesign that also... Why????? To protect the innocents maybe...

Take care,

Michel

Yes, he is the reference.

One of the site to get much info is:
http://www.otherpower.com/otherpower_experiments.html Their older site.

Good tricks there for construction. You have to go with a ratio of 4 magnets (on each side) to 3 coils setup and a star configuration for the coil connections. Many designs are outdated but a good read anyway.

Take care,

Michel

Edit: Go with the 2 rotor design, having one rotor (1 set of magnets) in not as efficient.

 Infringer-
  See if you can get your money back on automotive alt and conversion for it. Go to Otherpower.com and immerse yourself for a few months of quiet reading.... Don't ask them any questions until you have lurked and studied for at least 3 months.
  Do I sound harsh? Not intended, just factual. You can waste a LOT of money and time building marginal junk, or you can be on the
bloody blunt cutting edge of successful homebrew technology and learn how to make your own effective and (relatively) low cost wind
turbine.
  Have you looked at a wind map yet? Do you get decent wind where you are? Auto alt conversions need to spin fast to make any
power, 6 blades is slow, high torque- I know, gearing losses eat up speed and efficiency and geared turbines need higher initial wind
speed to get started.   You said 5 foot blades- do you mean 5' radius and 10' diameter, or 5' total diameter? If 10' diameter then you
might be able to gear up as much as 2.5:1 and still be able to push past cut-in speed... Depends on several factors. If only 5' total
diameter then forget gearing, and build yourself an axial flux alt (ala Otherpower) sized for your blades.
  Don't get mad and don't get discouraged, but DO do all your homework first so you can save some money for good batteries ;)

yes according to the wind map from 2007 14mph is common

Anyhow I have made my own observations I have had a decor type wind turbine up for some time now...

So my area is plenty capable of producing power from wind.

I have also read the whole otherpower website nearly did all of it sink in not really but I got 145lb n42 mags and 11lbs of 13 gauge magnetic coil I am working on getting the fiberglass resin and hardener...

I will take the altenator and the replacement stator as a loss for now...

I may do something with it though in the future stationary bicycle for charging possibly not sure yet ...

What I need from everyone is the best coil and magnet setup to achive maximal power I plan on designing a rotor and stator on the top and bottom of my VAWT to maximize power production should be fairly easy I plan to document everything too for those who are interested everything from start to finish but I do need to know the sizes of the rotor and stator and how to properly wind the coils for high output.

Besides that why go elsewhere why not archive the information here as well I see no reason not to have copies of the info here then that way if the website goes dead we still have that info.

I like the design using roof flashing but most likely I will be able to obtain my plastic barrels at little or no cost depending...

Hi Infringer,

The setup you describe is the Savonius Windmill design, at least for the wind part of it.

Take care,

Michel

14mph average?! YEEhaw! No wonder you want to put one in the air.....

OK, then.... 13 ga. wire, nice & heavy. Sounds like no more than 2-in-hand then. So what are the physical dimensions of your magnets?
How many of them do you have to work with? Are you designing for 12, 24 or 48v? 3phase? 5phase?
We have to size your alternator before we can size your blades. I would suggest you use used brake rotors to help keep the cost down,
and try to find the largest diameter ones you can. If you slip the guy at the Brake Depot (or whatever brake shop you go to) a fiver or
maybe a sixpack he'll probably throw them up on the lathe and smooth the faces for you so long as you swear to him that these are
NOT going back onto a vehicle.
Do you weld? You can save more money doing you own welding- no welder? 3 deep cycle 12v batts in series connected with heavy
cable works well, up to 1/4" thick steel...

I'm looking forward to your build- write back with the info and we can move forward with your design.

I am leaning to fiberglass and wood for the rotor and magnets for less drag if need be I will go carbon fiber.

Its all reasonable if you search for resin and hardener ... Just make sure the resin you use is compatible.  I've done fiberglass before and yes I have welded before as well more stick then anything else...

I want to keep everything sturdy yet light weight plus I want to minimize eddy current therefore I will not be using disc breaks sorry for not taking this route it just seems a bit overkill for what you are trying to accomplish when making a home made alternator...

Lightweight and sturdy is what I am shooting for something that will make use of lower wind and handle higher obviously I will need to do some balancing on the stator and rotor it appears that the stator (Stationary portion equipped with coils) is in almost all cases I have seen is larger then the rotor (portion that rotates with the magnets on it) just a hint the way I figure if you take the two barrels a little under half the distance should work and you can make the alternator quite a bit larger in diameter then the barrel itself my goal is roughly 4 inches larger...

Indeed I have 3 seperate posts discussing differnt topics about the build forgive me but this topic is kinda broad I was seeking specific help in the other  posts 

I wish I could do some decent graphics work then I could show you exactly how I will be accomplishing everything but give it time cause it may be a while before I get all the required equipment!
