How much power can a homemade windmill generate?
A small wind generator that you might put in a backyard might have a capacity of about one kilowatt. An average annual wind speed of nine mph would produce more than 200 kilowatt hours of electricity per year, and average wind speeds of 14 mph could produce more than 600 kilowatt hours per year.
What material should I use to make a windmill?
According to a report from the National Renewable Energy Laboratory (Table 30), depending on make and model wind turbines are predominantly made of steel (66-79% of total turbine mass); fiberglass, resin or plastic (11-16%); iron or cast iron (5-17%); copper (1%); and aluminum (0-2%).
How do you make a simple windmill model?
Attach a motor to the pinwheel to create a power-generating windmill. Remove the pinwheel from the straw. Place 3 to 4 strips of masking tape over the center of the pinwheel. Insert the shaft of a small motor and cover the end of the shaft with a cap, piece of cork, or a small blob of clay.

Are home windmills worth it?
Small wind turbines can be a cost-effective way to generate renewable electricity for your home. However, many residential properties are not suitable for wind turbines for a few reasons. For one, to generate enough electricity to make the upfront investment worthwhile, wind turbines need to be in a windy location.
Can I put a wind turbine in my backyard?
Most wind turbines aren't exactly small enough to fit in a backyard–since a bigger size means more energy, a single blade can be longer than a football field. And wind power can be noisy enough that neighbors sometimes complain even when a wind farm is miles away.
How big of a wind turbine Do you need to power a house?
A typical home uses approximately 10,649 kilowatt-hours (kWh), an average of 877 kWh per month. Depending on the average wind speed in the area, a wind turbine rated in the range of 5 to 15 kW would be required to make a significant contribution to this demand.
How thick is a wind turbine blade?
The turbine with the blade thickness of 2.6 mm and 10 mm have the highest value of Cp on TSR 0.3. On the other hand, the turbine with the blade thickness of 15 mm and 20 mm have the highest Cp on TSR 0.2. Overall, the highest value of Cp is 0.499 for the turbine with the blade thickness of 20 mm.
How do you make a small windmill for school project?
First cut the cardboard to shapes of windmill and glue them together to build the windmill. Then we create six blades for the fan, along with a circular cardboard. Make a hole in the center large enough for the wooden skewers to fit through it and glue six blades to the circular cardboard.

How much does a windmill blade cost?
Wind energy farms looking to stand up a wind turbine need to note in their budget a single wind turbine blade goes for $2.6-4 million on average. While using fewer, larger turbines can be beneficial, the cost rises as the wind turbine blade sizes increase.
How big of a wind turbine do I need to power my house?
Sizing Small Wind Turbines A typical home uses approximately 10,649 kilowatt-hours of electricity per year (about 877 kilowatt-hours per month). Depending on the average wind speed in the area, a wind turbine rated in the range of 5–15 kilowatts would be required to make a significant contribution to this demand.
Can a fan power a wind turbine?
After some painstaking work, he was able to turn a ceiling fan into a wind turbine (of sorts). While it's true that some generators and motors can be used interchangeably by reversing the flow of electricity (motors can be used as generators and vice-versa) this isn't true of ceiling fans.
Why do windmills have 3 blades?
A combination of structural and economic considerations drives the use of three slender blades on most wind turbines—using one or two blades means more complex structural dynamics, and more blades means greater expense for the blades and the blade attachments to the turbine.

How fast does an alternator have to spin to produce electricity?
Alternator may not generate sufficient charging voltage until alternator speed is greater than about 2000 RPM. Typically, alternators have their full output rated at 6000 RPM but can continue to spin up to 12,000 RPM or more without any additional increase in output.

How long does a windmill last?
A good quality, modern wind turbine will generally last for 20 years, although this can be extended to 25 years or longer depending on environmental factors and the correct maintenance procedures being followed. However, the maintenance costs will increase as the structure ages.
How much do small windmills cost?
Residential wind turbines vary depending on how much power they can produce and other factors. A rough range is $4,000 to $8,000 per rated kilowatt. A system that would offset most of an average home's electricity use (10,000 kWh/year) will cost roughly $50,000 before incentives.
Why do windmills only have 3 blades?
Any number of blades greater than three would create greater wind resistance, slowing the generation of electricity and thus becoming less efficient than a three blade turbine.
