I searched the engine for turbines and ventilators, cos in summer it's kinda hot here. And today my room-mate used a tool-box to keep the kitchen's door open, so that we possibly get sum air/wind coming through the kitchen's window and the corridor to cool the rooms of each one of us, but i guess i need an idea of a ventilator. Say, not a usual one like my ceiling ventilator that hardly compensates my comps' heat, but a kinda turbine that i can build and hook onto our kitchen's window. If i had more of them, i probably could stream the wind systematically through all rooms. (what i think about is a litle bit like water-pumps); air in these times is not moving, but you need air's movement to cool, so i have to get the air moving and a "kit" that you can build, eventually amplify to get a "bigger one" of the ventilators (for the main stream from the kitchen). I wanna stream my flat with air ! My room.mate went in a min ago and he said, i should try it in my room - sure, but i got my ceiling ventilator and that one sucks the air from abnove to push it downwards, but i keeps stayin the same air, cos it dun move it from outside the house to inside and out again. Umm, sry, i've drunk a lil bit and it was really a weird day today, so sorry, if it sounds weird. I just wanna get rid of the heat in here and wanna do my part as crafter against the condition as it is. So, if you got any idea, would be great...

Wind turbine questions.

I am asking these questions on behalf of another member who has English as a second language. He is building a vertical axis wind turbine (savonius style, I think).  The mechanicals don't worry him, it's the generator and the windings. He wants to arrange six coils and six magnets.  The magnets are going to rotate with the turbine.  He has made the coils himself - each is wound clockwise, with 100 turns of wire. He assumes (and I agree) that the magnets should be separated by 60° of the circle, alternating which pole faces the coils (S-N-S-N-S-N) and the coils should also be separated by 60°. He would like to produce 12V DC, to be fed into a battery. What is the best, or most appropriate way to connect everything to achieve his goal? Links to sites that he can examine (and/or translate) at leisure would be nice.  Or sites in Turkish. (I suspect that Picoturbine documentation would help, but it's in long English.  Still, I've added it to the topic in case it is of help.)

Wind turbine placement?

I live in a rural area and we have two blue Harvestor grain silos. One has a 25 foot diameter and is 90 feet tall and the other is 4 feet from it with a 20 foot diameter and is 70 feet tall. I was wondering if it would be possible to mount a wind turbine on top of the taller one. I don't know much about turbulence though, if there would be too much? Or how high it would have to be off to clear the turbulence? This is my first try at it, I was going to try a treadmill motor, something small

Wind Turbine help?? Answered

Okay, so I'm making a small Wind Turbine to charge a couple of Rechargeable AAA batteries. But my problem is that the motor I'm using only generates voltage when moving clockwise and one of the fin designs I'm using spins it counterclockwise... So I tried a VAWT designs and it spins it clockwise but not very fast... I'll post pictures so you can see the designs. Thanks!!

Dinosaur wind turbine

I am in Kenya and being of a technical persuasion have been asked to fix this geriatric wind turbine. It is an electromagnet (as apposed to permanent magnet) based generator that my friend bought from the Italian scouts. I cannot for the life of me get anything more than about 3V from it. Has anyone ever seen anything like this before and if so have any idea where on earth I might be able to find out a little more about who made it or how I might be able to fix it. I have tried everything I can and still no cigars. Any help much appreciated. I am here setting up this organisation if anyone is interested access(hyphen)wind(dot)com

Wind turbine to charge batteries

I have a solar electric system with a battery back up for power outages.(it is also grid tie) I would like to add a wind turbine to charge the batteries in extended outages with no sun and hopefully wind ( we normally have low wind but storm outages have lots of wind). The batteries are 12 volt connected in series to produce 48 volt. Can I, should I, get a 48 volt turbine and connect direct to the batteries or some other voltage and go through the inverter like the solar panels do and if so how and what voltage turbine?.. Chris

Parallelized Wind Power

This started as a blog post on Make was suggested to head over to instructables and get some stuff going here and it seemed a good idea. Also, in the meantime I found (of course) a bunch of cool wind projects here (about 20). I really like the vertical Savonius turbines. I wonder if those could be stacked with a similar effect?I've been wanting to do a wind power project for a while, and it seems like a good one to work on with others. Here's a brainstorm to kick things off. Please add to it or suggest alternatives problems etc.- total parts cost < $200- leverage off the shelf parts as much as possible. - little or no machining.- over 100 watts, (ideally 300-500) (this could be totally unrealistic with a $200 price, not sure yet)- usable in small yards, urban roof topsThe guys who made the original did some research for a grant and the paper is available here: Hopefully this is enough to kick off some discussion and gather up interested parties. I think the first step will be to tack down goals and solidify a general approach. Ideally in the end, we can come up with a good parts list from a minimal number of sources, and an instruction set that's relatively easy. A group might also leverage some purchase power by getting some of these parts in bulk (ie. a whole bunch of airplane props). Tim

Wind Turbine from a cordless drill?

Hi guys i have come across an old 18volt drill. i connected it to some small pvc blades about 12 inches long in the hope of generating some small amount of power. Pointed it into a reasonably stiff breeze but the blades wont turn due to the gears of the drill. Anyone out there got any ideas on how to make this work.  is there any way to free the gears so it turns easier or any advice on what size blades would be required to turn the motor.

ceiling fan wind turbine

I am in the middle of building a ceiling fan generator/wind turbine.  I know that the electric current produced is AC (I think it's 3 has 3 wires coming out of the fan). I do not know electricity that well, and am learning as I go... I would like to use the wind turbine to drive a small garden water fountain pump that is 120 volts.  What do I need electrically to complete building this wind turbine? Does anybody have any suggestions on resources on how to connect such a device electrically?  (Do i need a diode, rectifier, ???)  Does the voltage produced by spinning the generator have to equal the volts required by the device ( small water pump)?  Thank you for any and all help as I'm trying to learn and hopefully complete this wind turbine by summer.

Using a fan to drive another fan

Hi all, This may very well be a stupid question but after a quick bit of searching I cannot find an answer (which probably means it is stupid). I have been thinking about setting up a wind turbine to generate some electricity for my home. It occurred to my that it would be good if the wind turbine did not rely solely on the wind from outside so I started thinking about using another fan to blow air into the fan or fan used to create the electricity. Does anyone know if this is possible? I guess what would be ideal is if fan A was powered by the electricity produced by fan B but fan B also produced a little extra electricity that I could syphon off. This could then easily scale up to produce more power. [ fan A ] ~~~~~> [ fan B ] ~~~~~> electricity I suppose if fan A takes more energy to run than fan B can create then it won't work. Has anyone looked into this?

Apartment Wind Turbine ideas

Hey all. I would like to gather opinions on 2 small wind turbines I'm thinking of constructing. Difficulty: I live in a third floor apartment (it's also the top floor). My first idea was to modify an old box fan and mount it outside my window. Then I walked into my bathroom, which has a noisy exhaust fan in it. I accidentally turned it on and realized that I could build a collapsable darrieus turbine that would fit up the exhaust vent, expand when outside, and hook that up to the exhaust fan motor already in the vent. Does this sound feasable? My goal is to see if I could charge a cell phone from the power generated by one of these two options. apologies for the quick-n-dirty sketch below.

Question on wind turbine design

Are the poles on the top face of your magnets or at the ends? The former arrangement exists in circular disc magnets and the small bar mags used in brushless motors. You may find that you can get more coils in your motor by winding multiple winds around a piece of stiff plastic. Similarly with disc magnets, alternating N/S with a smaller gap between them you may have more magnets and more coils. Also in many hobby brushless motors, the gap between mags and coils is small, 1-2mm. Do you have the mag coil arrangement on both the top and bottom? I am assuming that you have centering bearings top and bottom, but do you have thrust bearings? These are cheap and are simply balls in a nylon ring at the cheapest end of the market. You would have to sandwich these between big washers or metal plate. I think if all of this was done, the efficiency and output would increase. Dave
