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.

This machine uses the power of the wind to knit one continuous sock. It harvested from time to time and sections are labeled with the time it was knit. Very cool.Be sure to check out the video in the link below. Wind Knitting Factory via CRAFT

I'm building a wind turbine for the first time and I want to share my progress and chat with people that have done the same type of thing. I'm a member of many different forums online and I value the information I pick up from them a great deal. (OK here comes the question) I've been looking for an online community of people that share this interest (residential wind power) but I'm not finding any large groups, or a central hub of knowledge. My question is , Does any one know of a large high traffic wind turbine forum ? My Googlefu seems to be weak in this area :(

Hi I have a UV-c wand which I acquired recently and instead of running it off mains or batteries I would like to make a wind-up charger for it (similar to the wind-up torches). It would also be good learning for me as I am a novice at electronics and it doesn't seem like too hard of a project. The mains input for the wand is 6v DC, you can also use it with 4 AA batteries. Instead of having rechargeable batteries I was thinking of having the winding mechanism to charge a capacitor. The UV light is rated at 4 watts and it would be great if I can get 3 minutes of use from 3 minutes of charging and even better if there was some sort of notification which would let me know when the capacitor was fully charged (like an led lighting up). Another way that I was thinking was that as you were winding, the light would be working at the same time, so instead of taking 6 minutes for the job it would take 3 minutes. Help and advice will be appreciated. Thanks

Any help here would greatly be appreciated. I work at a pizza delievery place where we use car top signs. In order to light up the signs we must plug it into the cig.lighter. I was thinking that it might be a good idea to use the wind from the car moving down the road to power the light in the sign to free up the cig. ligher for other things( Sirius radio). I have absolutely no idea on how to go about this. Anyone have any ideas? I would greatly appreciate it.

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.

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.)

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?

I play the ocarina. i got my very first one awhile back from my aunt alicia. it was from peru, and it had 8 holes. but 1 unfaithful day, as i was helping my sister clean our room, IT HAPPENED. the poor thing was in the floor under a pillow, and i stepped on it and *sniffs* it shattered! so my sister thankfully gave me hers. it's been about 4 years since that happened and now i have one made of plastic, and it has 10 holes, and it's a sweet potato ocarina.

I have a propeller with four blades that acts as a wind direction weather vane. What I would like is for the propeller to make a whistling noise when it is rotated by the wind. Someone told me if I put a small hole or a slit in each of the blades it will make a whistling noisy which should change with wind speed. Can anyone tell me what size hole/slit I would need? Also at what angle would the slit have to be? Or can you tell me any other way to get a whistle from the blades when the wind is blowing? The blades are metal and about 200mm long (400mm overall diameter).

Hi all can someone help me find out a way to make a wind up timer? - all it needs to do is manually wind up by hand, unwind through a series of gears slowly.....but needs to have a strength of about 2kg/cm torque. something to unwind for about 30 minutes would be perfect is there anything out there which can be used..or a simple way to make using spur gears and a coil spring? many thanks

OK, I have an idea that sounds kind cool but no working knowledge of electronics. How difficult would it be to make a bank of wind powered LEDS? A circut that progressively lights up more leds as the wind kicks up to a higher speed?

Hey guys, I decided to make a vertical wind turbine out of materials I had laying around in the garage/shed. I found everything I need; old bike, pvc/dryer exhaust pipe, old dryer motor. I wanna make something along this concept.... https://s-media-cache-ak0.pinimg.com/236x/b6/c1/cd/b6c1cd7b76e82cef51fefdfa4f62bfcd.jpg the wind turbine would be chain driven from the sockets on the bike wheel. I have the whole concept of the turbine drawn out and ready to go. But when it comes to the wiring on the motor im stumped. If someone could help me, that would be awesome!

Working in Haiti, Shawn Frayne, a 28-year-old inventor based in Mountain View, Calif., saw the need for small-scale wind power to juice LED lamps and radios in the homes of the poor. Conventional wind turbines don't scale down well -- there's too much friction in the gearbox and other components. "With rotary power, there's nothing out there that generates under 50 watts,"Â Frayne says. So he took a new tack, studying the way vibrations caused by the wind led to the collapse in 1940 of Washington's Tacoma Narrows Bridge (aka Galloping Gertie).Frayne's device, which he calls a Windbelt, is a taut membrane fitted with a pair of magnets that oscillate between metal coils. Prototypes have generated 40 milliwatts in 10-mph slivers of wind, making his device 10 to 30 times as efficient as the best microturbines. Frayne envisions the Windbelt costing a few dollars and replacing kerosene lamps in Haitian homes. "Kerosene is smoky and it's a fire hazard,"Â says Peter Haas, founder of the Appropriate Infrastructure Development Group, which helps people in developing countries to get environmentally sound access to clean water, sanitation and energy. "If Shawn's innovation breaks, locals can fix it. If a solar panel breaks, the family is out a panel."'Frayne hopes to help fund third-world distribution of his Windbelt with revenue from first-world applications -- such as replacing the batteries used to power temperature and humidity sensors in buildings. "ÂThere's not a huge amount of innovation being done for people making $2 to $4 per day,"Â Haas says. "Shawn's work is definitely needed.Â'http://www.popularmechanics.com/technology/industry/4224763.html?series=37

I was revisiting some of my old instructables, being a narcissist, and realized it had been two months since I posted my windbelt. Now I haven't done anything with it, it sits in the junk box, but considering the great excitement when the concept had first come out, I was wondering, has anyone done anything interesting since?

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...

WARNING: Mechanically inexperienced Newbie post below. Your patience is appreciated. :)Some of you may have seen this lamp online somewhere:http://www.hulgerisation.com/?page_id=60I'd like to try and make a lamp that works like this. As mentioned above, my experience is virtually non-existent when it comes to taking machines apart and hacking into them, but I possess a decent amount of common sense, and I'm pretty handy when it comes to tools. I'd like this to be my first project of this type. It seems simple enough: take a lamp base, a clock spring and a dynamo flashlight aaaand.... then what? Okay, so maybe it's not so simple. But to some of you, I'm sure it's probably a piece of cake, right? So if you've got the time and would like to explain how to do this, I'd truly appreciate your help.I found this instructable to be informative, https://www.instructables.com/id/The-Wind-up-Headboard-Reading-Light/but ultimately, it's not what I'm looking for. The key is the key for me with this lamp. It is visually appealing to me. Secondly, I would like lighting component to be that of a standard lamp- incandescent or CFL. If anyone has some kindly advice to offer, I would truly appreciate it. Thank you for reading!

I'm sort of undecided on the best way to go with a water pumping project and hoping someone had some advice/ideas. The goal: pump water from a small stream into a rain barrel (or IBC tote) in a location with no electricity. It's for having water available for watering fruit trees and doesn't need to pump much volume (even 100 gal/week would be great). It does have to do it while I'm not around though and I'd like to do it as cheaply as possible. My idea is to make a small diaphragm pump out of pvc (for the housing) and some rubber (for the diaphragm) and a couple check valves. My inspiration is this guy's pump. I could drive it with a small DC motor powered by a solar panel. Maybe install a float switch that turns it off if the barrel gets full. Any other ideas on making a diaphragm pump using cheap or found parts? I've never done anything with solar and would appreciate any advice on components. What needs to go between the panel and the motor, if anything? I've heard talk of a "controller" but have no idea what it is or what I'd need... Also a goal is to design using as low power motors as possible so that I don't have to spend much on panels. I've also played around with the idea of something wind powered, like this thing (but cruder, presumably). And had this other crazy idea to make a bellows-style pump for a windmill using a toilet plunger. Anyway, any thoughts and ideas are appreciated!

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.

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 :(

I'd like to know how to wind a torodial transformer with a toroid that I just happen to have. I would like it to work at 60Hz at 120 volts (US mains) and have an output of 36volt centertap (18-0-18) or maybe a little less (I'm building an op-amp powersuppply that gets regulated to +-12volts) and as many amps as possible (well, safely). The toroid I have is painted a light green with a blue ring on one side. it is 1.25" outerdiameter, 0.75"innerdiameter. It's 0.5" thick. It looks like the bottom left toroid in the picture below, just bigger and no wire. I do not know what gauges to use, how many windings (well, I know the ratio), how many amps it can deliver, how I should wind it, etc.

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

I'm looking at adding a not too obtrusive wind generator to a house I just bought. One of the best I have come across is the honeywell BTPS (Blade Tip Power System) - it isn't as sleek looking as a lot of the turbines I am looking at, but it seems like a good concept to me. http://www.earthtronics.com/honeywell.aspxI can't believe that this company is the first to come up with the concept; has anyone here seen any other similar systems, designed to run in the lower speeds/altitudes common in a smaller residential setup, but generating decent power?

Hi all, I would need your help with a project I have in mind... I've been at it in my mind for a while, but I'm getting nowhere fast, as I'm rather a newbie in electronics!! I did enlist a friend to help with that, though! ;) I would like to find a way to have the wind trigger the lighting/fading of a led, the same way one could do with a variable photo resistor (variable-resistor-wind-sensor-like, or could it be more slight-motion-based?). It needs to be compact and inexpensive, as I would need to make a whole lot of those. Ideally, it would be an analog sensor, but I am open to other ideas. No Arduino, though, please... I'm not there yet. Either one sensor for each led, or one sensor for a few leds at a time. It could be powered by an external battery. Any ideas? Thanks!

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.

On the morning of March 26th, on the dry Lake Ivanpah, The Ecotricity Greenbird driven by British engineer, Richard Jenkins smashed the world land speed record for wind powered vehicles. The Greenbird clocked 126.1 mph (202.9 km/h) , eclipsing the old, American held, record of 116 mph , set by Bob Schumacher in the Iron Duck in March 1999 at the same location.The fully-composite craft (the only metal is in some of the bearings) used a solid wing to reach speeds up to five times that of the actual wind.The wing also provides unwanted lift, so it uses the same downthrust technology as F1 cars - at speed, the 600kg car presses down on the salt-flats with a force of almost 10,000N.Greenbird website.

Good afternoon, Im making an exhibition piece that will have children working a set of bellows that are connected to a (pretend) blacksmiths forge. What I need to represent is the more the bellows are pumped the more the "embers" will glow. Im thinking a turbine tachometer that leads to an LED driver set to display as Bar so the faster the turbine spins the more LEDS are lit, or they trigger a series of LEDs to light (this thing has to get pretty bright not sure one LED per step will do it. Trouble is im good with the theory and pretty good with the practical its just the technical that is letting me down. If anyone could see there way to giving this some thought and maybe doodling a circuit diagram / shopping list that would be awesome.

This is best placed in the green group as it is for the production of green electricity, but I think that it would not be out of place in the science section also. I have an idea, quite probably not an original one but an idea all the same. It came about as we go camping as a family and have been off the grid a few times. Basically we have had no way of charging our electronic devices for longish periods. Solar power I hear you cry, well that is all well and good if you live in a country that has good sunlight, but here in the UK it can be unpredictable and not produce enough charge to power modern devices. I am mucking about with dynamo’s on the bikes (pedal ones) and wind up devices. Something I am looking into is things like wind power or improved dynamo power. The basic principal behind all of these forms of power production is that of passing a conductor through a magnetic field to produce a potential difference on that conductor. Simples (reference to meerkat advert http://www.youtube.com/watch?v=NBu0OtC6m9g). It has been a very long time since I have done anything like this (way back in school all those years ago) so please stick with me on this one. If I remember right the principal theory is that 1. The higher number of conductors (or loops in the coil) that passes through the field lines causes the voltage to be higher. 2. The stronger the magnetic flux the higher the current production within the conductors. This is a bit basic to some of you I am sure but I still need to get it out to confirm my thoughts. If this is wrong please correct me, as the title says, an expert is needed lol The bar magnet field lines project from the N end and loop back to the S end in this fashion Image 1 Putting two bar magnets together with N and S facing gives a field pattern like this Image 2 Now this is where I need the most help with. Toroidal magnets produce a different field pattern, and as far as I can make out from the internet it looks like this Image 3 & 4 What I want to know is what happens when you put two toroidal magnets on top of each other, what happens to the field lines then. I have thought that there are a few possibilities on this, the first is that the circular lines will extend to encompass both magnets creating like an hour glass formation in the cross section. The second is that field lines will combine/intermingle between the magnets and create a figure 8 pattern. In either of the two possibilities the field strength will be increased to what could be considered a focal point between the two magnets. So with the technical thoughts out of the way and progressing on the assumption that I am correct so far my thought of a high powered dynamo is this. A central shaft that is spun by wind or other means, attached to this shaft are disks like platters on a hard drive, attached to those platters are the toroidal magnets. The magnets are aligned and spaced to give maximum condensing of the field lines between the upper and lower platter. In the centre of the two (or more) platters is a fixed platter, not attached to the shaft and is stationary. On this stationary platter are the coils, fixed into position. Image 5 The coils are shaped and could be something like the voice coils out of a hard drive, which would be good as they would determine the size of the platters, being key stone shaped they will fit together to make a ring of coils. Image 6 The whole idea is based upon the maximising and focusing of the field lines from the magnets to a point producing the maximum amount of energy as the coils pass through the lines. I also think that due to the shaft being turned having little resistance or weight that even small amounts of wind energy would be able to turn it to produce the desired outcome. Now this is where I ask you all to comment and take my thoughts to bits where I have assumed things that are wrong. I have no problems being told where I am wrong as long as it is not in a nasty way. Cheers all

Due to the larger magnitude of solar PV power output fluctuations relative to those of wind at time scales shorter than approximately 31â2 hours, the costs of large scale solar PV integration are likely to be larger than those of wind.via Treehugger

Texas is now far ahead of California, and the rest of the country, in production of wind power.From the NYTimes:Texas, once the oil capital of North America, is rapidly turning into the capital of wind power. After breakneck growth the last three years, Texas has reached the point that more than 3 percent of its electricity, enough to supply power to one million homes, comes from wind turbines.Texans are even turning tapped-out oil fields into wind farms.
