Answer by freesiaoriental
Vibration is not so different from the movement of an earthquake…
Why do not you look into research done by the Japanese engineers?
There is a way to manipulate the foundations of the turbine or whatever it is so that the shaking will not affect anything it’s attached to.

Answer by Bob
Don’t worry about the vibration, first think about how you will deal with the horizontal forces imposed by the wind on the turbine blades, this will be transferred to the telecom tower and try to push it over.

Depends on the diameter and pitch of the blades.

Answer by bill
i would assume so, if there was no friction or drag acting on the second one, and All of the air from the first one hit the second one…..but there is friction and drag, im saying no

Answer by enginerd
obiously, the “energy” in the wind exiting a turbine is less than the energy of the wind entering the turbine by the amount of work done by the turbine plus losses.

the reduced energy is manifested in properties of the exiting wind including velocity

the change in velocity will depend on the orginal velocity, the size and design of the turbine, the load (say electrical generator or whatever) on the turbine and other factors

I recently saw an article on Yahoo news about a guy that purchased a wind turbine for personal use. He spent around $ 65k. He figured it would take about 8 years to pay for itself.
That might give you an idea on what to expect.

Answer by GABY
I work a lot in west Texas. They have thousands of them. Most of them are about 1.25 MW, and cost about $ 2,000,000-$ 3,000,000 each. That would probably serve about 80-100 houses when producing full power. Of course, you would need another source when the wind is not blowing over 6-7 MPH.
They also pay the land owner about $ 3000/yr lease payments. I do not know what the cost of connecting it to the grid, all the environmental permits, etc. would be.

Pretty costly power, but would be good for the environment.

Answer by j p
GABY’S answer is correct.

I knew of the price of 1.5 million Dollars per wind turbine, but in this price range a tiny more or less is rather insignificant, since those who dream about this could not afford to purchase one in the first place.

GABY please e-mail me the location of the retirement community in Mexico. I have been playing with the thought to retire down there myself, like so many others. It certainly would cost a lot less living there. Thanks in advance, JP.

Answer by billrussell42
Depends on the type of motor the fan has. Only DC PM (Permanent Magnet) motors will also work as a generator.

.

Answer by sweeti_butt
It depend on the size of the motor that is connected on the other end of the turbine. If you have small fan then you use small motor and get small power! But I do not think it will be an economical to produce electricity with fan, the reason is that you are using fan which is running with electricity, so first brief your question then I will clear you.

Answer by gintable
Wind turbine blades are specifically designed differently than fan blades, because it is more optimal to taylor the design to the application, even though in theory they have opposite energy conversions and could be geometrically identical.

The same is true with the motor and generator. Motors and generators both work in either direction, but they work superior when operated in the direction for which they were specifically designed.

How do I do this? DON’T!

Get a wind turbine and get an electric generator, both specifically designed for the application intended.

Answer by lare
if your home is in Alpena, you will need to get it past the zoning board first. While wind chargers is a green way to make electricity, the are also a miserable source of noise pollution.

Answer by cliffinohio
Good luck. The small wind turbines aren’t really cost effective yet. They are expensive, do not produce as much power as you use, and the payback is nearly infinite. So it’s unlikely you would spend your own money on one.

On top of that the “stimulus” money seems to be going to government agencies, not individuals.

But let me know if you get funding for it. I’d like to get in on that too.

Answer by Rudydoo
Hey Henry, good question. Actually, there has been quite a bit of work done in this area. Wind turbines this day are basically around 33% efficient. There are variations of course, the more blades a turbine has, the less its efficiency. Turbines with multiple blades are generally built for high winds, such as an arctic weather station, or on an offshore oil platform. The theoretical maximum efficiency for any wind turbine is 59%, it’s called the, “Betz,” limit, named after an engineer that did work in the field years ago.

If you want to learn more, you can go to the source. The American Wind Energy Association is a non profit group whos sole mission is the advancement of wind energy. There are some other places to look for information on the subject, I will list some other groups below. The easiest way to get right to the math work is to google, “Wind Turbine Efficiency,” and look for a link to an AWEA website. They have all the formulas and examples spelled out for you right there. There are a couple guys considered the gurus of wind energy, Mick Sagrillo and Paul Gipe. They have each written books and articles on the subject and instruct courses regularly as well. You might find some of their work on the web or at the library.

We have a wind turbine at our home in the Northern Great Lakes. It’s our third, the other two did not work out as well as we hoped. To be honest, this one is a good unit, but it’s had it’s issues as well. Wind turbines are not for everyone, but if someone has some acreage, good winds, and doesn’t mind fussing with the machine from time to time, it can be an interesting pastime, much like growing your own tomatoes instead of buying them at the grocery. Hope this helps. Good luck, and take care.

Answer by Prem
Hey Dude,
It is simple. Get a small DC motor. Get a Diode. Connect the diode cathode to the the motor terminal and anode to a LED and the other end of the LED to back to another terminal of the Motor.

Motor can act as a Generator, that is the point. Now to rotate it, fix a small fan at the shaft of the motor. Get a vacuum cleaner and keep it in blow mode. Point it to the fan to make the motor shaft rotate. This will generate small current enough to make your LED glow.

Presentation is the overall thing than the concept. People like to see, not to under stand.

ALL THE BEST

Go to the nearest “habitat for humanity” store, pick up a second hand ceiling fan, and mount it sideways on a pole.

Hi
building a small wind turbine is really simple – but you have to work carefully and ideal follow a good instructional guide.

Before you spend money, check with your local zoning department on their regulations.

Answer by rottendog93
You are superior off purchasing the equipment. It’ll take a high capacity system to do you any good. Geothermal would be a superior bet.

Answer by john h
You are wasting your time, at ideal wind turbines are no more than 22% efficient at ideal and solar panels unless you live in california or arizona I would think are next to useless.

Get in touch with a company called Daiken they manufacture an outdoor condenser unit which using hot water is far more efficient and therefore cheaper to run than gas fired central heating and you can use most of your exisiting central system with it.
