Answer by William Shanker
…most likely NONE as the cost of a wind-generator and everything involved in its construction and set up is ENORMOUS !

Answer by PointBlankResponse
You need like a thousand more points of detail in order to answer this.

-How huge a house/how much energy do you use? how much are you paying?
-where you get the turbine? how huge is it? how much energy does it generate a year?

Answer by Mohammad
Wind Turbines are costly and need a massive area to be constructed.

A 20kw wind turbine will cost you at least 80,000$ .

So, I think you save NONE!

Answer by Tim C
It depends on the purpose of the questionnaire.

Answer by Ray;mond
Will any one in your household object to noise and vibration from even a small wind turbine? If so, the turbine needs to be on a separate tower, not attached to the house.
Are there any nearby tall trees? If so, the cost of a tower taller than the trees might be 80% the total cost. Trees reduce the average wind speed. Worse trees cause variation in the wind speed from one second to the next. This increases the wear on moving parts in your turbine. Electrical watts out is proportional to the 4 th power of the wind speed = 6 mile per hour winds produce very tiny electricity.
Did you check your location for frequent high wind speed? If not you might be very disappointed in the watthours you get. Neil

Answer by Have a scientastic day!
just get a small electric motor. I recommend you go to a place like electronic goldmine to find one.

Just build a turbine out of balsa wood or cardboard, connect it to the motor shaft with glue.

Hook the motor output to a voltmeter or a couple of LEDs

blow on the turbine to make if spin and voila! electricity.

Answer by Stephen C
1. Vertical axis turbines are not as efficient as axial turbines.

2. 5km/h is 1.3m/s virtually no wind turbine on load will operate at this speed.

Answer by Snotalie
you should be able to cut 1/3 off your poweer bill. if you have three you could power you whole home.

Answer by Mr Radio Man
Very little… Windmills do not hardly make enough to power one home. Just use electricity…

Answer by starshyne59
Here’s the link to a map that shows the wind strengths in the US. This will get you started.

http://www.windpoweringamerica.gov/wind_maps.asp

Here is another site with some great information to get you started in your search for wind energy:

http://www.awea.org/faq/rsdntqa.html

The actual energy output will depend on wind strengths and durations in your area. Good luck!

Answer by billrussell42
wind makes the blades turn, that turns a generator that makes electricity.

for more detail, look at wikipedia “wind turbine”

Answer by mensajeroscuro
Well, a turbin works by recieving a flux of air at certain speed. This air hits the “fins” of the turbine and because of this they begin moving in a circular way. Then the air leaves the turbine with les kinetic energy than it had before and the rotational movement of the fins is the win’s energy turned into mechanical energy. This can be used to move an electric generator or anything else that needs mechanical energy.

Hope this helps.

anyway, how how much power does one produce? any stories on going wind power only???? any ideas. thanks

Answer by OrakTheBold
Depends on what part of Oregon you live in. You need a constant breeze of at least 8mph.

Take a look at this pdf:

Answer by bbullough
you will probably have to contact a supplier, and pay for the drawings. Firms seldom put that kind of detail out for free; they make some money by selling info and services. There are some general info available, such as this: http://www.windturbinewarehouse.com/pdfs/nordtank/Nordtank_150_SAC_DSM_4_20_07.pdf

Answer by dickn2000a
You have not provided adequate information for a reasonable answer. As inefficient as a Savonious generator is compared to other designs, the more massive the S buckets, the more massive the generators and greater wind or water flow… the more electricity they can generate. Without some defining parameters it’s impossible to answer your question.

Answer by Norrie
You do not use a motor (a driver) for a Wind turbine. The wind turbine uses the energy of the wind (as in a windmill) to drive a generator.
Go to a automobile dump and obtain an alternator. Connect it up to the shaft of the wind turbine and electricity should be produced.
A 3 to 4 -foot diameter wheel should be plenty huge enough for an alternator which will put out power at slow speeds (as when your automobile is idling in neutral, it continues to charge the battery).

Answer by aviophage
Sounds like you are attempting to build a miniature model for a science project, rather than a full-size turbine that might use a automobile alternator. The automobile alternator would require a massive turbine, maybe 15-20 feet in diameter, and a tall tower to place it on.

Also, a stepper motor can’t be used as a generator at all. That idea simply will not work.

What you need is a small permanent magnet DC motor of the type used in model railroad locomotives, slot cars, rechargeable electric tools, and the like.

If you apply torque to a permanent magnet DC motor, you can read a voltage across the windings. Such motors are available in hobby shops, electronic shops, and on the internet. Just pick one of the appropriate size for the model wind turbine you want to build.

Good luck.

Answer by jito11rivera
I would concur the previous answer. You seem to require a small motor, a PMDC is what you require.

YOu can find them anywhere….look at old toys that run on batteries, cordless tools that are broken, there are lots of them in junk automobiles (look for the window washer pump, or power mirror motors).

Nice place to one brand new is at Jameco on the internet.
They have Mabuchi, Johnson Electric, Star, and Igarashi DC motors…try the blow link. Good luck.
