How to Build a Wind Generator - DIY Wind Power For Your Home

How to Build a Wind Generator - DIY Wind Power For Your Home

Why would you want to learn how to build a wind generator for use at home?

Although there are a wide range of benefits that are acquired from creating wind energy at home, the two most important reasons of learning how to build a wind generator are financial and environmental.

Financial, because of the horrendous free fall of the economy and its effect on our pockets and environmental, because if we don't start helping ourselves, our planet will be changed forever as we know it. If we could all make diy wind power for home use, we could in some way help ourselves on both fronts.

It would be impossible to explain how to build wind generator in this short article but this is how you basically go about making one.

1. You can make blades out of household items. Wood/plastic.
2. These blades have to be fixed to the wind turbine/generator. The turbine turns wind energy into mechanical energy. The generator turns that mechanical energy into electrical energy.
3. A shaft to fix the blades to the tower, letting them rotate freely.
4. A tower to keep the whole assembly high enough to make optimum use of the wind.
5. A base to keep everything in place.
6. The generator feeds its electrical energy into a charge controller or charge regulator. This limits the rate of current that feeds into your bank of batteries thus helping prolong the life of the batteries.
7. A battery bank.
8. An inverter. Your battery bank will have stored DC (direct current). This is no good for domestic appliances around the house as they require AC (alternating current). The inverter converts DC to AC electricity.
9. The AC needs to be fed into your electricity control panel. This is where by means of transformers and circuits, the correct voltage and frequency for domestic use is output.

Note. At point 6, if you want to add solar energy to give you another source of free electricity, it can be connected to the charge regulator to boost your power. Good quality plans will not only give you the blueprints on how to build wind generator, but will also include plans on how to build a solar power system as an added bonus.

Diy wind power and solar power blueprints cost about $50 or so and explain how to build your alternative energy systems for as little as $200 each. With the cost of pre constructed wind generators starting at $600, good reliable ones at $2000, several diy wind power systems could be made for the same cost plus the blueprints are always there for you.

They can be fantastic projects to carry out with family, are a lot of fun to make and are totally satisfying to complete. There are many good motives to build your own wind generator and solar systems but hardly any reasons not to.

Make use of the free, environmentally friendly and renewable resources the surround us and don't let them go to waste.http://www.homemadewindturbineplans.com

DIY Wind Generator For Cheap and Uninterrupted Power

DIY Wind Generator For Cheap and Uninterrupted Power

Wind is a type of solar energy. The irregular heating of the atmosphere by the sun, the irregularities of the earth's surface plus rotation of the earth causes winds. This wind flow or wind energy when "harvested" by modern wind turbines can be used to generate electricity.

DIY Wind Generator: Principals behind the working

When wind moves over the turbine blades, it generates a lift. The lift makes the blades rotate and hence rotate the shaft. The rotating shaft moves a magnetic field in the generator which in turn creates electricity.

Wind turbine include following parts:

  • Gearbox - Gear box connects the low and high-speed shaft to each other
  • Blades - wind blowing over the blades causes them to lift and rotate
  • Hub - the sphere object used to mount the blades on
  • Generator - Generator creates at least 60-cycle AC electricity
  • Tower - Tower is the metal pole the turbine operates from. Tower is at least 100 feet off the ground so that the turbine can capture the least turbulent wind
  • Rotor hub - Rotor hub is the hub and hold the blades together
  • Yaw drive - Yaw drive is required only for an upwind turbine; it keeps the rotor facing the wind
  • Yaw motor - It provides power for the yaw drive
  • Nacelle - Nacelle sits on top of the tower and clings to the gear box
  • Low-speed shaft - It is turned by the rotor at a rate of 30 to 60 rotations every minute
  • High-speed shaft - It connects to the generator and drives it
  • Anemometer -Anemometer is used to measures the speed of the wind

DIY Wind Generator: How it works

Wind turbine generates electricity by spinning a generator. This generator is connected to the rotor, which is made up of three blades, which is then attached to a tower. To make the turbine face the wind, the rotor has a tail, which works as weather vain.

Our DIY Wind Generator is generally an electric motor. While the coils in the motor spins past the magnets, an electric current is produced. The power which is produced is stored in batteries, which are then connected to an inverter that changes the DC to AC, which can then be used to power your home.

DIY Wind Generator: Where to Place Them?

Preferably you should put your wind turbine where it's going to catch the maximum of wind. This implies that fewer the obstacles around your wind turbine the better it would be. The higher you can put your wind turbine the greater electrical output you will get.

Take care not to put wind generators right next to your house or under a tree. Try to find a place where the wind whips all the way through, and that's the place for your wind turbine.

DIY Wind Generator: Size of wind generator

As different Sizes of wind generator requires different Start speeds. So it is very important to consider the start speeds, which depends on the size of the wind generators. Larger wind generator starts at higher speeds in comparison to the smaller wind generator which requires lesser speed.

Wind generator generates electricity only when they spin. You should rather have two smaller output wind generators spinning than one larger one sitting stationary.

So opt on to wind energy which is inexhaustible, cheapest and eco-friendly renewable source of energy.

Building a Wind Generator

Building a Wind Generator

Building a wind generator is not a difficult task and you will be surprised to know that hundreds of thousands of people across the globe are producing electricity from their own home made wind power generators.

Electricity from renewable sources such as solar energy and wind energy are much cheaper and at the same time if you adopt these, you will definitely save our environment from pollution and global warming.

Actually you can buy a ready made assembled wind generator, however the cost of it will be in the rage of a few thousands dollars. The advantage of building a wind generator is that you can assemble it within $ 200 and therefore you have a potential to save thousands of dollars, which otherwise have been spent on buying the ready made generator.

Before you actually plan for building a wind generator, you will need to know the advantage of it especially the cost benefits of the generator. A wind generator requires space and height for installing the tower and blades of the generator and depending on the wind speed, these blades will move and will convert the wind energy into electricity.

Therefore before building a wind generator, you should also ensure that in addition to space, the wind speed in your area is also sufficient enough to produce electricity. If the average wind speed is below 5 miles per hour, the wind generators are generally not economical.

So, if you are sure that you get sufficient wind speed in your area, although most of the people live in areas where wind speed is sufficient to produce electricity, you can try building a wind generator at your home.

Start building a wind generator with the help of a guide available at Internet. If you follow the instructions given in guide, you can easily build a wind generator and produce free electricity.
