Tips on wind power?

I am looking for tips on creating a small windmill to charge a twelve volt battery. what is the best type of motor to use? Does anyone know how to make a charging circuit, so that even when the winds are low, it can charge the battery? What is the best type of battery? Are there any other questions i should be asking about wind power, and what are the answers to them?

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!!

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

Working Wind-Up

I'd like to build a manually operated wind up key( the kind where the key turns slowly) for my costume. One problem; I don't understand the mechanism too well. If you could break down how it works as well as the parts that I would need to create such a device would be greatly appreciated.(P.S. I'm pretty new to this so if you could take that into consideration that would be great too).

Connect a wind powered generator, producing AC power, directly to my house?

What is needed to connect a wind powered generator, producing AC power, directly to my house? I've been looking into wind generators that use F&P Smart Drives. But all of the information I've come across is how to set up a DC system. Based on what I've read, and I'm no electrician, the F&P Smart Drive should be able to produce enough AC power to reduce my electric bill substantially. I'm hoping to find a list of parts, equipment, or a kit that an electrician would need to complete the AC connection. Thanks in advance

I would like to use my 110 volt Jacobs windcharger to charge my 48 volt battery bank. Then possibly switch over to water heat elements as a dump load when the battery bank is full. This last step could use the full 110 volts. The Jacobs is rated at 20 amps, about 3000 watts.

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 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.

wind generator blade speed

Okay. now I have a grasp on my amp (or should I say watt) draw. I now need to figure how to make this wind turbine produce what I need. I've bought a small 200 VDC motor to build my first turbine from. This is just my 1st hobby wind generator to see if I can & how well. Probably the wrong one, but it's cheap enough and sure I'll use it for something in the future. 400 rpm seems really fast to generate 12v! So that's my first question... is it? To achieve this speed , in my area (Class 2) I can expect 4 hrs a day wind of only 3-7 mph (trying to stay very modest), so I assume I need multiple blades and gearing. 2nd question; How do I determine how many blades, of what size I should make to obtain a certain rpm in a particular wind speed? Not sure I asked that correctly, so please bear with me. Once I have this generator in hand I will be able to measure the torque needed to turn it. Then I assume I need to determine a blade size and count to meet this need. If that is still not enough, I assume I will then need to gear it and re-calculate the blades. Anyone out there have the math to figure this?

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?

A min-wind turbine tower possibly tree like form

Http://www.megagadgets.nl/en/products/minikin-wind-charger-p-1265/ The image above show the small windturbines I would like to use withouth the battery compartiment, or something like wise. with the stormy weather, I was wondering if a vertical colum 3 wide, and say 3,5 m high could not be used to generate electricty. I then thought it would be better if it liked a bit like a tree, have a tree shape. So that in the bottom 0,5 m there are no mini wind turbines, but at the top end it would have tree like shape filled with them, all generating there bit of power and adding that to a battery system. As I consider it possible that to much power could be obtained, so the excess power would go to a kind of art installation. I wonder how to fabricate such a small turbine myself, but also what windspeed it could have, and how much power each one could generate. e.g. could it generate so much power that it damages itself. It may not be the most efficient form as that a small windturbine would do the same, but in total it would be flatter and with a nice color i´d like them more. I don´t really like the grayish color of those big ones they build along the road. The idea behind it is that you can then ´plant´ a forest of them. The images are merly to given an idea.

Guys need help to realise its feasiblity and pros & cons. This project will comprise of a renewable energy source which is controlled by TI msp430 controller by closed loop system. This renewable energy source will use a magnetically levitated vertical axis wind turbine with single phase permanent magnet alternator made by our team. There will be 3 stationary wind guide vanes/flaps of concave shape on the outer periphery of turbine. These vanes will be controlled by dc gear motor for constant wind flow and protection against high speed winds. Using perturb & observe MPPT algorithm on DC-DC boost converter, constant DC voltage for GRID integration is made. A lower energy Bluetooth module will send data on user computer about whole system parameter, hence making the whole system to be smart and hence data is saved in database. https://www.youtube.com/watch?v=fC5hYLjhO9U
