Build Your Own Windmills and
Protect Our Fragile Environment!
If you are reading this article you probably know already that alternative energy is something that everybody should turn to. Not only it will save you hundreds of dollars on electricity bills, but it is also eco-friendly and it will make our planet smile. One option to consider as alternative energy is windmills.
But you may ask yourself: How to build a windmill?
Before researching how to build a windmill, we must take into consideration the things we need for its construction. First of all, you must figure where to place the windmill. This is very important because an improper placement will lead to a low output of your energy source. You must make sure that there arent any obstacles near the windmill, like trees for example. The wind must blow with its full strength into the windmills blades. Its also good to know the direction the wind most frequently comes from.
Measure the prevailing wind speed on your property before considering a wind generator. In order for wind energy to be cost-effective, you need a wind speed greater than 8.5 to 9 MPH at least sixty percent of the time. Any slower, and the turbine won't spin fast enough to generate much electricity.
Now, in order to have a clear image about how to build a windmill for our own, it is recommended to build a miniature windmill first. For this you need only a few tools, like glue, paper, tape and a stick. Try to build this first, for a better understanding of how a windmill works. This should clear your mind a little before you start building the big one. Once you know how to build a windmill in miniature, youll understand better how to build a windmill for real.
For that, we must know the parts that form a real windmill. Of course, there are many little things that bring the whole piece together, but the main parts that you must focus on, are: the base, the blades, the tower and the gear box.
A simple way to utilize green energy without a huge installation cost or commitment to equipment is to buy green energy from your utility provider. Many utility companies offer customers the option to buy their energy from renewable sources such as wind, solar, or hydro. This allows you to have a positive impact on the earth without extra maintenance on your part.
The strongest part of a windmill is the base. It must be very solid and heavy because it sustains the entire structure. It must provide stability and strength to the windmill. For that, concrete is recommended as the main material. Still, sand bags are an option too.
The blades should have an aerodynamic shape to catch the wind. They can be made of carbon fiber, but if you want a more common material, wood is a very good one. For the windmill to work more efficiently, dont use too many blades. It will only slow the rotation. Two or three blades are usually enough.
Natural sources of energy can be unpredictable, which is why you should always have a back-up plan. Find out more about net-metering plans: in most towns, you will be allows to hook your system to the main power grid and use it when there is not enough sun or wind for your green energy solution to function properly.
The tower should also be strong and some proper materials for it are PVC pipes or aluminum. Finally, the nacelle (the gear box), for a personal windmill, can be a shaft, so it can link the blades to the tower, in order for them to spin as easily as possible.
Many people give up on the idea of building a windmill because they dont know how to build a windmill. But if you study the concept a little youll find out that it isnt that hard. Use the free power of the wind and start saving money on electricity.
