build your own wind turbine

Post by hydrogen » Mon Jul 11, 2005 9:22 am

found this today, very interesting. It could be easily modified to be a water turbine. peak of 3.8 KW!

i know, i have been on it all day. i have learned a lot in a short time, theres some small water turbines that can charge a battery bank, and then there is massive wind turbines, i think this is valuable knowledge that we all should know incase TSHTF real bad.

More efficient generators are vertical-axis turbines.
These windmills do not need another axis to rotate into the wind, since their airfoils (on the lift-type designs) can garner windpower from anydirection immediately.

Not neccessarily. I have personally witnessed several sites with wind-power potential here in missouri. Up near a town called Macon, its damn windy. It may be true that this isn't a really windy state compared to other flatter states, but there are certain areas that receive a lot of wind. About 25 miles south of where I live, there is a sustainable living center that has many wind turbines generating electricity for them. They look to be around 100 feet off the ground.
For those interested, there is a two-part article in "Back Home" magazine, issues Jan/Feb 2005 & Mar/April 2005 on how to make a homemade wind generator. Its pretty cool and uses a brake drum as the hub.

Unfortunately, VAWTs are not self-starting, and exert great forces on itself, which means more maintenence.

http://en.wikipedia.org/wiki/Wind_turbine
and
http://en.wikipedia.org/wiki/Wind_power

have some amazing information.

I think this is the power of the future, or should be. Nuclear's too expensive and messy, we've tapped all the hydroelectric we should, and solar is way too inefficient. Yep. Wind's where it's at.

Hello
I have just found theese sites
http://www.poormanguides.iblogger.org/i ... p=magnum52" onclick="window.open(this.href);return false;
and
http://www.windplans.com/?hop=magnum52" onclick="window.open(this.href);return false;

I am realy interesting in homemade wind generator.There are a lot of plans how to built it (on internet) but you know most of them must be paid in advance.
I am quite curious if They are worthy of buying.So If you have experience with building wind generator please share them with us :)
Thanks

Welcome Karo.

This is quite an old thread, but that is ok.

Do you plan on building one from scratch or buying components and putting it together? You do understand that a scratch job would require a machine shop to get it together.

I plan to build one from scratch but I might buy some parts (blades, engine). I want to know how to build it by myself from garbage only in case.It would be great if I found some plans which help me build my own Wind generator.You know plans - step by step.

i was looking into wind turbines and i got to say i like the idea and wanted to get into it. i thought the above link would be a good place to start i know it really cant power much but it would give the basic idea.

then i would like to do that one

just wanted to get some input

FWIW, I've seen plans that utilize the box style window fans. You do have to replace the AC motor with a DC motor that has magnets (as opposed to field windings), but once done, you can mount it on a length of pipe in the yard. A larger diameter, capped pipe, holding the turbine assembly, slides over the first pipe, and a tail on the opposite side keeps the box fan facing into the wind. Several of them, tied together could provide more power than you might think, to look at them.

I'm just starting to skim the surface of the topic, myself. I understand how they work, and I know enough electric to make the connections to everything, I'm just not comfortable with my level of education regarding things like how big the blades need to be for a given wattage output range, how close together you can put them before there might be some interference, things like that. I'm also interested in why the blades are shaped as they are, when my initial impression is that an airfoil shape, like the wing of an airplane, might be more efficient. Since better minds than mine are the ones developing them, I guess there's a good reason for it.

I'm planning on doing solar first, and am still researching that, as the technology has leaped way ahead of what it was when I first learned about it. After I get that set up done, I'll look into wind power, as the location has a pretty steady breeze, if not full-on wind, almost all the time. The reason I'm not going with wind power first, is that I'd have to mount the towers in an active pasture, and I'd like to minimize the footprint of the towers, while maximizing the power output, and all the towers would need to have the lines buried- a LOT of work on an 80 acre farm.

I've only made tiny ones for fun. They only produce a couple of volts, but I suppose in a good wind could charge something like AA batteries. My problem is I live in town, and don't think a 10ft diameter turbine on a 30ft tower would fly with my neighbors.

This thread reminded of a page I read a while ago How I home-built an electricity producing Wind turbine.
He made a relatively small, powerful and cheap wind turbine - it cost him $140, he did have a few of his own parts and it was 4 or 5 years ago. Still, it could still be done quite cheaply.

Otherpower is great. They have a copy of a very good article somewhere on the site spelling out exactly the kind of wind speeds and blade diameters needed to produce enough power to run a house. It's larger than i thought. Much too big to put up in suburbia without the neighbours breaking out the pitch-forks.


But i suppose in a survival scenario you'd only need enough power to, say, charge a 12v battery (to power your 12v camping equipment perhaps) or 5v for usb-charged stuff. Something that only produces 10 or 20 watts would be a lot more portable. The tricky part would be getting it up into the wind.
