Electricity is one of those things that nobody wants to do without, but nobody wants to pay for it either. Then what do you do? Well, there are actually a few different ways to get electricity completely free (or at least almost free) if you are willing to do a little work to get there. There are three different methods of power generation that are most commonly used. These include solar, water and wind power. Of course, we can not explain all of these methods in this small article, but we will talk about how you can make wind power work for you.
Wind turbines are one of the best ways to generate electricity, but they do not work everywhere. Not all areas of the world get enough wind to supply electricity through this method. However, some areas will receive sufficient movement of sunlight or water, so these are other viable options to consider if you are not able to cross the area. However, if you do (and there are tests to determine how much wind energy moves through your area in a generalized time frame) you can definitely use this particular item to help you get better and cleaner electricity.
What does the aerogenerator do
Wind turbines (the part of the generator that actually picks up the wind and uses its power) works similarly to a fan. Now a fan will use electricity to create a kind of wind.
On the other hand, the wind turbine uses a blade mechanism to create something that looks like a fan but is actually absorbing the wind instead of creating it. You see, the blades of a wind turbine will only turn if there is already wind to push them. When the wind pushes the blades, an axis (the low speed shaft) will begin to rotate. This causes movement in the high speed shaft located inside the gearbox. Then, the gearbox will feed the generator and electricity is created.
The types of wind turbines.
Currently there are two types of turbines that are used. These are the horizontal or vertical axes. Vertical axis turbines are the ones that are most recognizable, as they are often seen as large windlasses protruding from the ground. On the other hand, the horizontal axis turbines have a more elongated shape and the blades rotate around the central support instead of rotating without the support.
These turbines can be constructed in a variety of different sizes, from very small (enough to feed a single house) to extremely large. There is no doubt that you have seen wind turbines at some time recently, as they are becoming increasingly popular. Large wind farms are also becoming very popular with a large number of windmill turbines in a small location. These are generally located in fields, although they can also be placed in the sea.
A traditional turbine, one that is used for commercial purposes, is generally capable of producing more than 100 kilowatts of power (up to several megawatts). Smaller turbines, used for domestic purposes or for pumping water, are generally only capable of 100 kilowatts or less of power.
These smaller turbines are generally very different from their larger counterparts in some key ways that we will discuss in the next section. These are not capable of feeding more than a single installation with ease and will not be able to take advantage of so much power in a single period of time.
Small wind turbines
As mentioned, a small wind turbine is capable of producing only about 100 kilowatts of power. This is enough to feed a house or a small company, however, it is not capable of producing much more than necessary for these uses. These smaller turbines are also not necessarily 100% “green”.
Instead of taking energy only from the wind and taking advantage of it to use it in the form of electricity, some of these smaller turbines are connected to diesel or battery generators to simply supplement the energy produced. In most cases, this is done when traditional electrical methods are not available.
Why use wind turbines?
There are several reasons why you (or someone else) may want to use wind turbines to generate power. On the one hand, electricity is expensive. Most people depend on the government to generate electricity for them and that means they depend on the cost of that electricity.
Do not really have much to say about how much you pay and if the electric company decides to increase your rates? Well, you really do not have anything you can do about it, right? But if you generate your own power, you do not have to pay those high rates.
Another benefit is that some areas will actually allow you to sell energy to the power company. What this means is that if your windmill generates more electricity than your home needs, you can connect to the electricity in the community where you live and sell the extra.
In fact, you can earn some money by generating your own power (which can often help offset the costs you paid in advance to create your generator). Now it is only allowed in some areas, so you will have to consult the rules, but it is definitely an interesting area to consider.
Finally, many people use wind turbines because they want to protect the environment. Many of the traditional forms of electricity generation are not good for the environment and can cause damage to both the planet and the animals that live here.
By generating your own power, you can protect the planet and help conserve a large amount of energy. When greenhouse gases are used less frequently and even natural resources that have a finite supply help preserve the earth. For many people this is reason enough to generate their own electricity.
Your homemade windmill generator.
Building a wind generator is not as easy as you might think. Although at the same time it may not be as complicated as you may think. This is because a wind generator will require some skill and a lot of equipment, but once you know what you are doing, you can reassemble it relatively well. Also, once you have done it the first time, it will be easier if you ever decide to add another generator for your home or for a friend.
Now, if you are going to build your own wind turbine, you must make sure that your area will support it. First, this means that you need to have permission from your city, municipality or other governing body. You must ensure that the construction and installation of a wind turbine will be allowed as some areas will not allow it to do so (a wind turbine will occupy some space and will definitely be visible from other houses after all).
You should also make sure that the area in which you are building has enough wind to run your turbine. You will not want to spend all your time and money creating this turbine only to discover that you will not even have enough wind in your area to use it. This is definitely not going to be a benefit for you. So be sure you can calculate the average wind speed in your area. The ideal amount would be something more than 10 miles per hour relatively constant. Now, if you can get higher, it will be better for you and your results, so keep that in mind.
The turbine blades will be one of the most important parts of your windmill. This means that you must pay close attention to what you are doing with them or where you are getting them. If you do not, you could end up with a turbine that does not work or does not work as well as you need it. Be sure to carefully consider this component even more than the rest of the parts of your windmill to make sure it is of high quality and that it works the way you want.
You can choose to buy your blades from a reputable manufacturer or you can create them from anything from wood to PVC pipes. You will want to use a traditional number of blades (three) for your turbine because this will provide the ideal blend of efficiency and power.
You can get the most power from your turbine because three will allow the turbine to spin more quickly than if you had to add additional blades. Also, three, like an odd number, is better than an even number like four, because an even number of blades are more likely to increase vibration in your turbine.
The next most important component of your turbine is the actual generator it uses. You want to make sure it is high enough to provide power to your entire house (or whatever you have chosen to connect it). This means that it needs to be able to maintain a high voltage and that it can be used with a low rotation speed. This will ensure that it is compatible with your turbine and your windmill. Must be able to generate at least 12 volts constantly.
Most likely you will come across a DC generator, so be sure to get an energy inverter to convert your electricity to AC before you enter the house. If you use an AC generator, you may not have enough electric field to produce what you need. You will also want to have a deep cycle battery bank and a charge controller to connect your generator and inverter, as this protects both peak power and low wind periods (that way you will not have to buy additional materials). ).
Putting together a homemade wind generator.
To start, here is a video of a commercial wind generator that is being built and installed so you can see how they really look and how they work in the commercial arena.
A wind generator will require three blades (we have already commented that in the last section), a bucket, a head shaft, a generator, the vane, the flange of the iron floor, the nozzle of the pipe, the base, the duct , the charge controller, the battery, and isolated wires. Each of these pieces (along with a variety of screws and bolts) will work together to create the wind turbine and generator that will be used to power your facility (be it a house or a business or anything else). You want to make sure you have high quality parts so you do not end up with a product that does not work properly.
The first thing to do is take your three blades and attach them to your hub. You want to make sure that they are approximately 120 degrees apart from each other and that they are angled in the same way. This will allow the blades to turn in one direction instead of simply being hit by the wind. If they are not evenly spaced or if they are tilted in opposite directions, you may not be able to get the power you really need from them when the wind blows.
You can create a 2 x 4 head shaft if you do not have anything else and it is meant to keep the blades out of the tower. This will allow the weather vane (which will be attached later) to get the breeze and turn on the turbine. Do you want a hole approximately? to 1/3 of the downward stroke of the 2 x 4 so that you can place the generator closer to the hole and pass the wires easily without tangling or the turbines get stuck when your blades turn.
The generator must be connected to the spindle axis at this point. You can do it with metal strips or with blocks of wood or PVC. You will want to protect your connectors from the elements. Keep in mind that the metal can oxidize easily and the wood will begin to rot.
If any of these things happen, it can cause problems to your turbine or it could even be damaged, stop working or be completely disarmed. By protecting these parts from the elements, you will not have to worry about these problems (although you will still want to check your turbine frequently and assess the damage).
Place your wind vane on the opposite side of the head shaft. The palette does not need to be large or complex. In fact, it may simply be a piece of sheet metal that is about 1/3 the length of the 2 x 4 you used for the axis of your head. You can easily place this palette on the axis of your head by simply creating a small slot on the 2 x 4 and placing the palette on it. This will help your turbine turn when the wind starts (since we all know that the wind will not come from the same direction all the time).
A 1-inch piece of iron floor flange will be used under the spindle shaft to support the entire shaft. Be sure to screw it correctly and firmly to ensure that it will support the shaft and the parts above the shaft. Then you will want to screw a 1-inch tube nipple into the flange. This will allow the turbine to turn with the wind and allow the turbine to move in the manner that the vane directs.
Finally, connect the blades and hub to the generator shaft and check that everything is balanced. Both sides of the piece you have built must be level and uniformly weighted. If there seems to be too much weight at the end of the paddle, you must add some weight to this side to level everything before continuing to create the tower for your turbine. Note that if this piece is not level before it starts, it may end up with a top heavy turbine and could break when the whole piece is placed at the end.
As you build your base, remember that you will support the entire turbine. This means that it must be strong, big and heavy. If you want to create a permanent base, you can do it with concrete or sandbags. Remember that you want your base to be horizontally at least 1/3 of the height of the tower.
Make sure you know how tall your tower will be before starting this step or take the time to resolve it before completing your base. You will also want a 1-inch diameter tube placed in your concrete base before it dries and attaches to a 1-inch tee and a tube nipple. This will allow your tower to stop.
Cut your conduit for the tower making sure it is thicker than the pipe nipple (at least 1 inch in diameter). This is the height of your tower, so be sure to measure carefully before cutting and keep in mind the diameter you used for your base when cutting this tube. Once you have cut your pipe, you will be ready to put the pieces together and start using your wind turbine.
Connect your charge controller to your battery before connecting it to anything else, as this will prevent power spikes (which could ruin your turbine before it starts). Next, make sure that there are insulated cables connected to the charge controller and make sure the unit is disconnected from the battery so you do not have to worry about turning the blades while trying to install the turbine. You do not want the blades to hit you and you do not have to worry about the electricity that runs through the system as you move the pieces.
Pass the cable through the base and into the shaft of the tower from the T that you installed on the base to the top. It can take a little time and effort to make the cable reach the end or you can use a rope to thread the cable to the top of the turbine.
Remember that you want to do all this before actually mounting the tower shaft, so it will be much easier to thread the cable through and out of the top so it is ready when you are ready to start your turbine.
Use clamp cables to hold your shaft while mounting it on the base and then mount the head of the wind turbine on the shaft. Be sure to pass the cables through the top and connect them to the generator. You want everything to be installed correctly because shorting cables can be difficult to replace once your generator is fully assembled. Connect all your cables to the generator and reconnect the cables from the base to the battery so that the turbine starts spinning. You are ready to start enjoying your electricity (almost free).
Creating your own wind generator is not for everyone. It is something that not everyone can do due to government regulations, but it is also something that not everyone will want to do.
If you are interested in generating your own power, this is an excellent way to do it. If you are just looking to save some money or are trying to save the planet, you can definitely make a difference with your own generator. Not to mention that it can be fun to do some things on your own.
