I am interested in wind farms and I going to make a wind turbine for the science fair any websites for tips and directions

I'm interested in the Vertical Axis Wind Turbines (VAWT) produced by a Findland company called "Windside". Can anybody who has one, or knows of someone who operates one, actually attest to the viability of their low-RPM alternator/generators, and wind turbine designs?

I'd like to use a small VAWT on a condo roof, or to power an electric car or truck, like this one:

where or howto make a bladed prop for a wind turbine small 10 and 18 volts max per generator

Ok,
Were learning about renewable energy in high school, and were now talking about wind energy and turbines and generators and so on and so forth.
Well I was wondering, If you have a small scale wind turbine (fully functional, a little larger than a desk fan) and you had it so that the electricity it made would make a fan (or another electrically powered wind source) turn. If you put that fan in front of the turbine, could it be like never ending?
Or would the generator in the turbine not produce enough electricity to run the fan?

I was wondering if it wold be possible to rig up a mini wind turbine on the top of a camper van so that when you are driving it would create energy to store in a battery.

Or would the extra energy needed to drive the van due, to the drag from the, any energy made by the turbine?

If so can you get mini camping turbines?

Thanks,
Martin.
Thanks for all your replies, they are great!

The plan is to use the turbine to charge a separate battery, not the actual one used to start the car. The second battery will then be used for music, laptop and other small electrical appliances.

I saw a guy on the UK version of Dragons Den who had a mini turbine but I was thinking that someone else must have done it already!

If anyone knows of any websites that sell them then that would be a great help too!

I look forward to your replies, thank you all so much!

I am making a very small scale model of the wind turbine for science class. I need to find a really small generator. Where I can buy that? If there isn't one, if you know if any substitution for a device converting mechanical energy into electrical energy, please refer me to it. Thanks!

I'm studying an article on wind turbines. The article says that for electricity generation, a wind turbine rotating at high speed providing a low torque is preferable to a turbine rotating at a low speed and producing a high torque. Can anyone explain why this is the case? Surely the speed could be altered easily using a sequence of gears before the generator?

i am looking forward all kinds of generators which can be used in wind turbine(wind farms).
i search about real types and industrial of generators, not mankinds or labratoars ones.
thank you

i am doing this for my design technology and i am creating a wind turbine a small one for home use and i have to create a questionnaire, nd i have already ran out of questions to include.

I have a debate coming up about the Wolfe Island Wind Turbine Project (The second largest wind farm in Canada). The debate is whether or not the Wolfe Island Wind Project, as well as wind turbines in general, are beneficial to the environment or not.

I know there are the simple answers that wind power is renewable and that it doesn't generate any pollution (except in production it does). What I am looking for (without much success) are the BIG reasons why wind turbines overall benefit the environment (looking at environmental, economical, social reasons, possibly compared to other types of energy). Can anyone help? Links to websites would be awesome as well.

Hi Everyone, I am working on a business plan which I need to submit to an investment board in Pakistan and a some other countries by December 2011. After speaking to numerous people and reading many journals I would like to know what would be the equipment specification and cost for:
1) Wind turbine for 20 small houses (only lighting, perhaps 2 bulbs and heating the gas stove) would be required.
2) Solar panels for the same need.

I understand batteries and additional equipment will be required if someone can answer these question for me I would be greatly appreciative. The first market I would like to target is rural Pakistan and the resources for both the solar and wind initiatives are as follows:

The average daily insolation amounts to approximately 5–7 kWh/m2/day. Especially
the southwestern province of Balochistan and Northeastern part of Sindh . There the sun shines between 6 to 8 h daily or approximately more than 2300–2700 h per annum. The average daily insolation of 5–7 kWh/ m2/day means daily sun energy of 18–25 MJ/m2/day is available as
input natural resource of energy to be exploited for photovoltaic power generation or solar thermal applications.

Wind speed from 5 m/s to 7 m/s persists in coastal regions of Sind and Balochistan provinces
and in a number of North-West Frontier valleys

Given this data could someone be kind enough to tell me the kind of equipment required to power a small village on 20 or so households for just lighting and heating the stove. My business plan intends to alleviate the poverty of these villagers who have been living in Darkness for centuries and to improve their environment.
Any information will be greatly appreciated.

And how does the Wind turbine actually work?

long of a payback period -the amount of time it takes for the amount you save on your monthly utility bill to equal the amount you paid for the wind-turbine (without any government subsidies)- would you consider reasonable?

If a unit was made to be highly durable, and the payback period was 7 years but the unit was designed to last 30+ years, would you consider that a reasonable investment?

B Question: Seeing as many of the units currently on the market are hideously ugly, what style elements or design cues do you think might be more appealing to consumers?

I am doing a project for my college, Im coming up with a petition to get a big wind turbine to power a 1000 student college. I need big wind turbines, not residential there too small. websites would be great

I almost bought a wind turbine. I want to be able to harness natural resources and I'm worried about our polluting of the planet.

But.... I'm glad I didn't invest in a turbine.

When I pressed the vendor if he could stand by his claims for the power generation, he went all furtive and withdrew his original offer.

He said I'd get my money back and even be able to sell electricity BACK to the utility companies. Sounds brilliant.

But he couldn't give me a single example of anyone that does this.

In the past, I've bought a couple of solar panels, and neither of them worked.

I do use a wind up radio though.

Can anyone help me? I want a real example of power generation. What's the average power generated by a wind turbine? (I want the real figures, not the idealistic figures)

I looked a Hugh Fearnley-Whittingstall's river cottage web site, which publishes daily figures for power generation, and the figures don't look too impressive.

I want to build a machine that translates my physical exertions into useful energy. For example. If I could row for an hour, I might be able to turn a drum and get my laundry done.

Or cycle on a stationary bike and use that energy to turn a turbine or grind up all the packaging from my dustbin.

Where do I start looking for equipment?

Thanks

I like to know how much it would cost to by a wind turbine to power my home an that includes professional installation. How much on average would i have to pay yearly for maintenance costs. Would i get a task cut from the government. If you can answer my questions that would be helpful. Thanks!

I want to purchase a 60K wind turbine and plant it in 29 Palms, CA wind farm. If all the electricity produced is returned to the power company, what would the monthly yield be?

if i needed to power a pump with these specifications:
1.5hp, 240v, 8a
how many watts would the wind turbine need to supply?

I live in a subdivision and previously thought using wind power to generate electricity was reserved for people with more acreage.

I was watching "Living with Ed" on HGTV and I see where he has installed a small, cylindrical wind turbine on the side of his house and I wonder who makes it and where I can get one.

Does anyone know about "subdivision-safe" wind turbines?

topic, im looking to use .5" neodymium magnets to build a low resistance wind turbine, and i dont know how to determine what would be the best size of coil & diameter of wire to generate a given amount of electricity per rotation/etc...

can someone please help me? id be ever so greatful!!

It seems to myself to be common that when someone opposes the dogma of AGW, or proclaims that the risks presented by elevated atmospheric CO2 are overstated, that the accusation inevitably comes that they are receiving money from 'Big coal, oil or mining'.

Do these people not realize that companies typically have broad portfolios. An energy company is likely to have both renewable and fossil fueled generating assets. For instance in my country of Australia the three major energy companies all have stakes in coal, gas and wind power generation, often with hydro and other renewables tacked on.
By the same token large Oil companies do not solely produce fuel for vehicles, they also produce lubricants and other industrial chemicals which will remain in demand irrelevant of any need to reduce carbon dioxide emissions.
Same goes for mining companies, renewable energy options still ultimately consume raw resources that come out of the ground, from the aluminium in a wind turbine to the silica in a solar cell.

My question is that why does it seem to be suggested that reducing carbon dioxide emissions is going to be so detrimental to these companies that they would fund online bloggers, when the reality is that these companies still have a huge stake in what is considered the alternative to fossil fuels.
Isn't it far more likely that all that a reduction in the consumption of coal for power generation or oil for transport is simply going to force these companies to change their business model, rather than render them economically inviable?

I am working on the design & manufacture of small scale wind turbine. I need help in determining the size of model should i get manufactured for testing in the wind tunnel for its accuracy. What parameters are necessary while scaling down the actual blade design? In other words, what should be the ratio of model size to the internal cross-sectional area of wind tunnel?

I am making a small scale wind turbine for school as an independent study. I will be following the plans on the following sites/videos:

http://www.wonderhowto.com/how-to-make-wind-powered-generator-with-make-magazine-272175/

I will need a way of measuring the power generated and will probably require a battery bank to do this.
I'm sure it will depend on what motor (generator) I use. I was planning on using an old treadmill motor if I can find one and if not probably one of these:

http://banebots.com/p/M4-R0062-12

My question is what form of battery should I use? I have a relatively tight budget and would need the biggest bang for my buck. Should I use a bunch of 12 volts? larger? when it comes to batteries I'm kind of clueless so any help is VERY MUCH appreciated.
It will be running for quite some time and I need to track how much energy I can generate over an extended period of time without using a logging tool (they cost too much)
