DIY wind generator - Things to remember

Here are some basic tips to remember when you are building your homemade DIY wind generator.

Generator Tower

You need to be sure that the tower is sturdy enough to hold your structure under the highest winds that are recorded in your area. A good idea is to look up the previous maximum wind velocity over the past year because you do not want your structure collapsing. Also remember to allow the tower to pivot at least 270% so that it will move with the changes in wind direction.


Windmill Tail

If your tail is not big enough then your wind generator will not be able to rotate with the changing wind direction. You can even sand the edges a bit to make it more wind dynamic.


Blades

Wind velocity determines the amount of blades you should have.

  • High winds = Less blades
  • Low winds = More blades

HINT: Be sure to attach the blades at an angle and if possible with a slight twist to the blades themselves, this increases efficiency.


Generator (battery)

As a basic rule of thumb remember this formula:

The higher the voltage of the generator then the bigger the rotor needs to be.

You can relate this to different sized cars and fuel consumption. The bigger the car the more fuel it consumes because it has a higher energy demand.


Build your own windmill

If you seriously want to build your own windmill then I am telling you now to have a look at the link I have at the top/right of the screen. It will show you diagrams and a link to the best instruction manual you can find.

DIY Wind power

Did you realise how much energy can be generated from wind? Do you know that over 80 countries in the World are using commercial wind power because it is environmentally friendly and there is not a limited supply of wind, opposed to fossil fuels.

Principle of wind power
To put it simply the wind force creates rotation of the turbine blades which generates energy that is transferred to the attached generator. A basic example is when you ride a bike your legs create rotation of the peddles that generate energy transfer to the wheels that create your acceleration.

Can you create your own wind power?
Yes you can do this on a smaller scale and build your own windmill. It is obviously much smaller than the commercial windmills you see but the principles are the same and you can build a windmill from most house hold materials and at a small cost to yourself. If there is wind power of about 10mph then you are looking at a situation that you are going to save yourself quite a chunk out of that utilities bill.

How do I build a DIY Wind Power Generator
You need a few things:

  1. Time to do a home project
  2. A relatively steady wind current
  3. Basic home tools
  4. Some building materials
  5. Windmill Plans
