Wind Dam

Architects and designers Chetwoods have proposed building a wind dam. A giant sail would funnel air flowing through a canyon into a wind turbine to generate electricity. The pictures look unreal, even for CAD models, but the idea is pretty cool. More here at Inhabitat and Ecotality Life.

wind generator ?

Has anyone had experience in using magnets to help propel a horizontal wind mill or vertical wind turbine .what I mean is putting them in a circular series where the north propel against the north creating , forcing or helping the windmill to move in a circular motion?

Coil winding :(

Someone please help me.. My hands are getting so tired from doing this!! Ok, My first attempt was simple, Put cardboard on sides of pen, hot glue it down, wind coil. Works great for 18 22 gauge. Got some new 14 gauge wire, well, its A LOT harder than I expected :( What can I do to make winding 40 ft of 14 gauge wire fast and easy? Is there any way I can get it on a power drill or at least something that will make turning it easy? After 2 neat layers on my pen and a lot of tight holding, the 3rd layer started pushing the lower layers away, making the coil get messy :(

Wind Generator

Hello Guys, I am working on a small project that involves wind energy, I am basically looking for a generator, preferably DC and as small as possible, my goal is to generate at least 17V and between 1.5 and 2A.  Does anyone know where I can find something like this? Thank you Alejandro Moncada

Inductor winding?

Once again, I come to you for help. I recently became interested in some kind of 555 device metal detector. The schematic calls for a 10mh inductor. However, my local Ripoffshack doesn't carry inductors, and instead I decided I could make my own. It's just a coil of wire right? Right, so I have some formulas to find inductance given things like length and width, and I wondered if there's anything I need to be aware of. Does a ferrite core increase inductance? Where can I get a ferrite core? Do I need one? Is there a sweet spot for inductors? Thanks, Mr. Merino

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 harmonic generator?

I had this idea a while ago. There's a nylon strap strung between two trees. It's let's say 2 cm wide and 5 meters long. A strong wind is blowing across it so that the strap is resonating, displacing through, say, 20 cm at 10 Hz. What is the maximum power involved? If you had one or more wire coils running the length generating current, what kind of efficiency over all could you expect? I'm thinking of this as an ultra cheap and easy means of wind generation.

Parallelized Wind Power

This started as a blog post on Make http://blog.makezine.com/archive/2008/05/parallelized_wind_power.htmlIt 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: http://www.speakerfactory.net/TURBINES/GRANTS/Selsam%20EISG%2002-18%20Final.docAlright. 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

Methods for winding coils

When I read up on the coils used in power generation, I found that the wire used is a type of magnet copper wire, and I bought 1600 feet of it on ebay. My only problem now is winding the coil. I figure I can do something like wrap it a few hundred times around a pole thats slightly larger than the rare earth disc magnets I got. Anyone have any suggestions? Btw, most of my information is adapted from normal rotating wind power generators.

Wind turbine to charge batteries

Wind Power Charge Regulators

Hello!! I need some help here...I am very "green" when it comes to alternative energy, so bear with me please! I recently decided to put together a small wind generation system to power my workshop. System is comprised of a 38v Ametek PMDC motor, 6.8' tri-blade array for propulsion. I also intend on installing a 2000 to 3000 watt modfied sine wave inverter powered by my battery bank to provide AC voltage to the shop. I want to be able to used the majority of the power created by my wind generator. I understand the concept of using a "shunt" but do not have a need for hot water or useless lighting. My question is this, would the Flexcharge NC25A charge controller (www.flexcharge.com/flexcharge_usa/products/nc25a/nc25a.htm) be sufficient enough to used in this system? Or is there something else out there that would maintain my battery bank without shunting the load when the bank is fully charged....Thanks in advance.

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 phase...it 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.

Wind Powered Quad-Cart

I haven't seen anything this on here so I thought I'd step up. Engineers (or anyone who fancies themselves A DIYer) I found a few days back I little some very interesting Wind Powered Rides...six-or-seven-ways-wind-powers-vehicles OK so we know it CAN be done, but can it be done by a DIYer? OK here's my concept, Design and shape are optional but basic components are such: Take a pair of multi-speed Bicycles, their gearing will be the basic propulsion for this vehicle. Take one of the "bikes" and hook up a prop where the pedals "where" and set the wheel output to be higher then the prop speed, this should take care of the foreward movement once going. Now for the initial starting power (Bike 2), this can either be by petal, or by electric (solar/battery- up to you) But the basis for this whole thing is simple energy transfer, if the moving air over the prop causes the drive wheels to go, and by having them geared higher, the vehicle SHOULD move faster the faster you go ..Right? Can I get some math to back this up? it sounds like it would work.

Wind-up motor for a blower

I have this idea for a desktop toy which needs a blower. I could just use an electric blower, but I'd rather make a wind-up motor instead. I'd like the blower to spin pretty fast, to make enough air pressure to give the effect I'm looking for, but I don't want it to conk out after ten seconds, three to five minutes would be acceptable. I was thinking I could salvage the parts from something like an antique wind-up record player or phonograph (because they run pretty long), but I'm on a tight budget and I'd rather not destroy something that cool already. Please, any help would be much appreciated! Thanks! I'll post an instructable of my final product (if it ever gets done!)

Wind-powered phone-charger

Here's one for the tower-block dwellers - a wind turbine you stick to your window. On the inside, you stick the matching base-station, and the set uses electromagnetic induction to transfer energy from the spinning turbine to the phone in the charger's cradle. It's a neat idea, but I don't know if it's a real product - I tried tracing the links back, and ended up going round in circles in the blogosphere. What I am sure of, though, is that somebody reading this has got the skills and motivation to build their own version.  You don't need to use the same design of turbine blades, and it's up to you how it sticks to the window (suckers?  magnets through the glass?), but I bet you can do it. Just remember to post an Instructable. Traced back to Yanko Design.  Originally seen on NOTCOT.
