How to electric generators work? (Wind turbines etc.)?

I know the basic idea – turn a magnet in a coil of wire. But we did that in school and we could barely make a light stay on for more than a few seconds consistently.

So what is the design behind the generators in wind turbines? How are they actually designed in a real world situation (Not a toilet roll middle with some wire round it).

How do I make a model wind turbine?

I have to build a working model wind turbine for a science project. It has to actually produce energy but it cant be built from a kit nor can it use fancy equipment as it has to be made from house hold materials. I’v searched many web sites but i just cant find anything. Please help!
Thanks in advance

What are the some applications of trigonometry?

I know that trig is use mainly by surveyors, navigators, map makers,etc.
But how can a person like me, who is not a scientist nor professional mathematician to use trigonometry in everyday lives?Please give me some examples of problems where can I use it.(for example in home)
And please explain the solutions.

I just want to know because I found trigonometry to be hard if I didn’t know how to apply it.

Heard of new wind turbine with no blades?

I heard from my biology professor about a new type of wind turbine that was designed in Michigan that doesn’t have any blades, so it doesn’t effect birds & bats. Instead it has this circle thing at the top that twirls around.

Has anybody heard of it? I’m trying to find an article on it so I can add it to my wind turbine paper but I can’t find a thing.

im trying to find the size wind turbine i need. ive figured out my daily usage of electricity now i need to figure out how much a turbine makes per hour.

Comparing and contrasting wind vs. solar power?

I have to write a paper on something in english and I figured this would be a good topic. So I need help from people to tell me what they know about wind and solar power and any other things related. Any kind of information would be helpful. If you know a scientist or someone who does research on this kind of stuff then it would be great if you could also tell me their names because i have to add some sources and I think an expert on the subject would be perfect! Even a teacher would be good. If you get anything from like a magazine or an article of some kind please tell me the title of the article. (it’s fine if you don’t know any of the peoples names or articles title) Thanks.

Didn’t really apply myself in highschool, but now im 25 I want to become a ME. Is is impossible?

I really do believe being a Mechanical Engineer would be awesome. Not to mention there is a demand for it, and probably will be for years and years. I never was the smartest in highschool, in fact because I didn’t appy myself as I should, some classes were failed. Later on I made them up and passed them, some math. I have never taken calculus or physics before. Would it be a waste of time to go for a ME degree 8 years after highschool? I have GI bill that will pay for 36 months of schooling and tuitions. Im really interested in this field, and I do believe that if its put in front of me, and I put my heart into it, that I can do it. But I just don’t know in my case not having the necessary experience in math and having to learn what I need and possibly re-learn some, if its possible. Obviously I would need to take college transfer classes and all the basic courses. Is there anyone out there that decided to go down this path long after school, and been sucessful with it? Any motivation or reality check would be helpful. Thanks

how should i get the wind turbine to connect to the generator and the meter..do u know anywhere to buy pre made small windmilll/windturbines to hook up to generators

Is growing population really the problem.. or is it more like greed of consumption?

When we mention a population problem, people imagine an overcrowded world. There are six billion people on the planet. If everyone stood within five feet of each other, each person would take up five square feet. That would be over 150 billion square feet. Texas, for example, is well over 14 trillion square feet. All the people in the world would fit comfortably in a small space about the size of New Jersey without touching each other and all the rest of the land on earth would be empty. This is a population problem?

Will wind generators be outlawed since they are killing birds such as eagles?

The massive fiberglass blades on the more than 4,000 windmills have been chopping up tens of thousands of birds that fly into them, including golden eagles, red-tailed hawks, burrowing owls and other raptors.

It is illegal to kill eagles in this country. So will the windmills be outlawed?

Robert N. Patrick Jr., 51, was fined $1,275 recently on a federal charge of violating the Bald Eagle Protection Act and using a restricted-use pesticide.

Should they be banned?
lonewady – what a great answer. If you kill a bald eagle, you can go to jail. Without coal you would not be able to give stupid answers on Yahoo.

how does a wind turbine generator work?

I think I’ve designed a new wind turbine and I need to start thinking about the generator part. How does an electricity generator work in this case and where might I procure one in the UK?

why does the government not want a low cost way to make power?

7 years ago, I designed a short, low cost wind mill that will power two generators, yet the government that claims to want renewable energy has been in battle with me for years because they don’t want me putting the coal miners out of work. Can anyone tell me why the government will say they want a renewable energy source, yet refuse to allow mine?

What does it take to feed into the power grid?

because of the harmonic whatnot of the power grid – separate wind turbines, for example, have to be aligned to the frequency of the circuit to feed into the power grid

I understand this – but what does it take to have this occur?

What’s the least an individual would have to do to be able to do this on a small scale?

for instance, to be able to plug something directly into their wall socket that would be able to sell electricity back into the grid – by reverse-engineering a treadmill for example, resistance to power a motor – to sell energy back into the power grid?

how does a wind turbine produce electricity?

i have homework for school and i have no idea what the hell i have to do! this is the brief that was given:

You will be expected to describe how to produce an electric current by rotating a magnet in a coil of wire, as in a dynamo, and to describe the factors that affect the size and direction of an induced voltage.

please can someone help?

thanks.

Would increasing wind speed change the optimum design for a wind turbine?

I’m doing a project where I’m comparing the energy gain for a wind turbine at low speeds (5-20 mph) to an increase around 300mph (hypothetically), and I’m wondering whether or not a increase to that speed would change the way we would approach the design of a wind turbine?
