Essential Advice About How To Make A Windmill
Buying a ready-made windmill can easily cost anywhere from 12,000 to 30,000 dollars, so it is worth considering how to make a windmill for oneself. Actually, doing it yourself is very easy and can be done for less than 200 dollars. This will not be as big or grand as the shop-bought variety, but the potential savings are really significant.
So, what does it take to build your own windmill? Before starting to build your own windmill you should do some research:
- Average wind speed in your area. In spite of what others might say, windmills do not operate very well in average winds of less than 10 mph. The US Department of Energy publishes detailed wind resource maps, which should be consulted before making a windmill.
- Building Codes. Find out if you will be allowed to build the type of windmill you want. These usually allow the erection of small windmills, but it is best to make confirm this.
- Space available for the windmill. For a small windmill you should allow about half an acre.
- Next-door neighbors. Consult neighbors first about your ideas, and prepare to overcome any prejudices about possible noise, TV interference and so on.
- Windmill size. You only want a windmill that will generate enough electricity for your needs. The utility company will not buy any surplus from you, only offset against any power you draw from the grid.
- Batteries. If you want some independence from the grid you will need to include storage batteries. These are available for free if you know the secret source!. Or plan to use your windmill to partially offset your utility bills.
Getting the answers to these questions right is a little tricky, so it is really sensible to ask for expert advice before you start building. You will then be able to select the right plans for your circumstances, and make sure these include full lists of materials needed for the assembly as well as clear-step-by-step instructions.
You need only a few components to build your own windmill. Typically these are:
- A propeller (actually 3 propeller blades fixed to a hub)
- A DC motor
- A fantail
- A mounting shaft to which these are fitted
- A mounting pole
- Probably an inverter (to convert DC to AC)
- Storage batteries
With some electrical cable and a collection of nuts and bolts, that’s all you need. You probably have most of the necessary parts in your shed but, even if you have to buy them, you will find it possible to get all required items for under 200 dollars. It is quite feasible to assemble and fit a small windmill in a weekend.
