Wind powered turbine power generators are available from many sources but they are unfortunately expensive. A lower cost wind powered generator would solve this problem for many power consumers who would like to generate all or part of the power they consume. Not only does this help mother earth but the free power from the wind is a money saver into the bargain. Plans for building a low cost wind turbine from auto parts,wood and a few odds and ends are readily available.

A small wind power generator can be mounted on the roof of a home or other building or can be free standing with its own support. Several can be built to supply all the power requirements of the home or business and excess power produced can be sold to the local power company in many areas. This is a wonderful business opportunity for anyone who can build these wind turbines at low cost and sell them to people who do not have the time or skill to build their own.

Any cottage,farm or even city home can be powered by electricity generated by the wind. Those who live far from a power line need not be without power. Wind power is one of the green forms of power generation which does no harm to our environment. It is in fact the cleanest form of power generation which can be harnessed at reasonable cost. Solar panels are also very “clean” but they are costly and have low power output.

The average person,who has some experience with a home workshop,can easily build wind turbines from new or used auto parts,some wood and simple tools. Several can be built for the cost of one commercially produced model. There is a ready market for these since many consumers want to install them to generate all or part of their power supply. Plans with instructions and illustrations are readily available for anyone who wants to start in this business,in their home workshop,or even to make a turbine or several for their own use. Why not get into this business now? The time is certainly ripe for any product which will help preserve the environment and save money at the same time.

WIND TURBINES

About the Author

John Mowatt is a retired business man who is interested in wind power as a means of producing clean “green” electricity. He has researched means of building wind powered generator turbines at low cost and has found that this is a great business opportunity.

However, are you aware that wind generators are very difficult to actually get up and running. There is five major things that we should address when it comes to dealing with wind turbine efficiency. These are the actual wind power, the altitude, any obstructions, the aerodynamics of your wind turbine blades as well as the temperature of the air.

Let us look at wind power first. There is a special formula that involves P = Wind Power, V = Wind Speed & F = Wind Force. So when put together P = kVF and in this case k is a constant. Basically what this means is you want a faster wind speed and a stronger wind force in order to generate more wind power from your wind generator. Areas have different rates of wind, so it is vital that the relationship between the speed of the wind and the amount of power being produced is understood.

The second factor is altitude. For this the best places to set your wind turbine will be on higher altitudes. They tend to have faster wind speeds due to varying factors in the atmosphere. Elevated areas will also have less obstructions in the path of the wind in terms of hills, trees or even buildings. It has been calculated that you can get a 12% increase in wind speed if you double the distance from the ground to your turbines.

The third factor is obstuctions. When you are surrounded by trees, hills, buildings or mountains your wind speed is much slower. This is because there is some friction generated that actually restricts your free air flow. If you are building a wind farm it maybe wise to evaluate the speed at one site for a whole year just to make sure that it is a good site to sit your turbines.

The fourth factor is blade areodynamics. Essentially your blades should be well designed and shaped so that they allow for maximum efficiency. Each airfoil will have its lift determined by the angle it has with your wind direction, also known as the angle of attack. The larger the angle of attack the more turbulence generated by the blades. You will also lose lift and the drag will increase too.

Lastly but not least, is the fifth factor which is air temperature. The power generated by your wind generator increases by up to 16% if the temperature drops from +20 degrees to – 20 degrees at any wind speed rate. This is because colder air tends to be more dense and ultimately increases the power being produced by the turbine.

There you have it a five factors that will affect the efficiency of your wind turbines. All of these five should be considered whenever a new generator is being installed into an area. This will ensure that you will get the maximum amount of wind power from your new installation.

It was also noticed that smaller blades will not spin faster, this just defies the laws of physics. It does not matter the shape of the blades, it will never slice through the air. If smaller blades where more efficient we would see them on all those huge wind generators we see in our growing wind farms.

The second thing  they looked at was the number of blades that each wind generator should have. It has been discovered that four to five configurations of blades do not help anything. They are actually less efficient than the tradition three bladed wind generator. Again we should look at the wind generators on the world’s growing wind farms, you will notice they all have a three blade configuration. If more provided more power, I am sure all these gigantic wind generators would have four or five blade configurations.

What actually happens is that any blade over the third one actually slows down the wind turbine by causing turbulence. The wind turbine with more blades may initially have a slower start up speed than the three bladed one, but as soon as it starts up, it will create a considerable amount of turbulence that your wind generator does not really benefit from. The other blades will then waste their energy on trying to overcome the turbulence.

So there you go, if you are planning on building your own generator at home. You now know that you only require three wind generator blades, any more than that will not generator more wind energy. They will instead cost you more in the long run. If you want a good blade for your generator, you should purchase the longest one you can afford. It does not matter if it is made of aluminum or steel the longest one will generate more wind power for you.

However now, a US company is offering a propellor free personal windmill, that can be set up in a city or surburb. They call it the Wind Spire. It can generate 25% to 30% of the power in your house. The 3kw version which is twice the width and the same height will generate 100% of your households power requirements.

This new generator was included in a green exhibit at the United States botanical garden located in Washington. They designed it from looking at an old version almost three thousand year old that was found in Egypt and utilized for grinding wheat. Independant tests have been conducted in Utah to show that this type of wind turbine can compete with the ones found on traditional wind farms with the huge blades.

The wind blades of the larger turbines are infamous for killing birds and bats. This is because their speeds are usually way faster than the speed of the wind, and this also means that they tend to produce more noise. The Wind Spire vertical axis wind generator however, is very silent and does not pose too much of a threat to birds. It has been designed to spin at only two and a half times the speed of wind so it is always visible to birds at all times.

The company has started installing the 9m tall devices which can plug into household power and customers can see on their home computers how much electricity they are getting from the wind turbine. It is equipped with a wireless transmitter which tells how much power is being produced and how fast the wind is blowing. All of this information is relayed to your home computer.

This type of generator is from the vertical axis wind turbine family. It consists of a rotor assembly that has more than two hundred disks stacked on top of each other with a narrow two millimeter gap in between each one of them. On the circumference of the rotors is a bunch of twisted blades made of airfoil, whose sole purpose is to redirect the airflow to the surface of the blades.

They have designed this generator to harness wind energy to the maximum possible extent. There are many different ways that this assembly produces wind energy from the wind. The first way is the most common way which is the standard way in most generators. It involves the simple lift and drag via the blades on the circumference of the rotor. The other way is through adhesion, which is when the air enters the gaps between the disks and adheres itself to the surface. This ultimately increases the rotation of the main rotor.

The Tesnic home wind generator is very small and compact, which means you can easily install it on top of your house, on your roof. A lot of research and development hours have gone into the design of this type of generator, in order to make it super efficient. It does not hurt to know that this is a very affordable wind turbine for any household.

If you are familiar with how other charge controllers work, like those for solar panels for example. You would know that they simply monitor the battery voltage and once the batteries are fully charged, the controller shorts the panels. This type of device does not work for wind generators, because they could burn out your controller or even destroy your generator.

Included with every Whisper is the new Whisper Controller. The Whisper Controller includes a diversion load to ensure quiet safe operation of your wind turbine when the batteries are charged.

It installs in minutes and it protects both your wind turbine and battery. The Whisper Controller fits easily inside your battery room. Add the optional LCD display and you will instantly receive real time data on the performance of your Whisper 100.

The display can be mounted on the controller or up to 1000 (300 meters) away letting you know what is happening. You can even add an anemometer to your controller and now you can measure wind speed and compare it to the output to make sure you are getting the most from your Whisper 100.

You maybe thinking why not just unplug the batteries once they are fully charged? Well, that will not work either because most wind generators will overload when they have no load and then go on to possibly damage the generators. This happened to a friend of mine recently, and he was not amused by this at all.

So this leaves installing a wind generator charge controller as your only plausible option. What this does is allow the batteries to fully charge, and the automatically switch to an alternate load that can continue to use the power being generated by the wind.

Some of the things you can use the extra energy include heating your water, powering your household refrigerator or even just using it for lighting the home. Wind generator charge controllers are available in different voltages such as 12V, 24V, and 36V to suit any model wind generator.

No wind generator installation could work well without a controller, your are doomed to mess up your own set up. This may result in you having to invest in a whole new generator, costing you more than it should have. So whatever you do make sure you have purchased a charge controller for your whole installation.

To help you with your learning venture, here are some quick facts about this energy source that is wind power.

Kinetic energy is formed when air moves that causes wind. This is the kind of energy that is created when mass is in motion. The kinetic energy coming from the wind can be captured using the right technology developed by humans. The captured energy can then be converted into various forms of energy, including mechanical power and electricity. During the early years of its development, people in EuropeChina used windmills to capture the energy from the wind and convert it to power up grind grain and to be able to pump water. As of today, the more advanced wind turbines can be used as a stand alone to power up utilities and machines or can be used to support other systems like the solar power to create more energy.

The source of wind power is natural, clean and inexhaustible. This can actually be used for a long term goal for these reasons. This is also safe for the environment because not only this is clean, it also doesn’t cause pollution to soil, air and water. It doesn’t create wastes that are hard to manage like the wastes being created by nuclear power.

3. The location is the main problem that is usually encountered by those who want to build huge project to set up machineries for wind power. This must be done on areas that have large tracts of land. This can also be created along coastlines or in places where the wind movement is at its full force. These areas are usually devoted to the development of agriculture and urban growth and development.

4. Through time, people will realize how cost-efficient this project can become. There are various wind power designs that are continuously being developed to make the project more feasible as years pass by.

Your best bet is to find a professional who deals with this kind of project. They can give you an estimate for the whole project and how long can it be done. They can also give you clearer ideas as to the benefits that you can gain when you have decided to set up your own source of wind power.

Brief Overview

The source of wind power actually starts from the sun. This is one form of solar power. The reason for this is the fact that the wind is brought about by the sun’s heat. Heat radiates on each part of the Earth’s surface on an uneven level. The heat radiates on various kinds of surfaces like water, stone, sand and different types of soil. These surfaces absorb, maintain, reflect and then release the heat at various rates. This state causes the Earth to be warmer at day and cooler during nighttimes.

The air that can be found above the surface of the Earth warms and cools in various rates as well. When the hot air rises, the pressure that can be found near the surface of the Earth is reduced. Through this, cooler air is drawn to replace the hot air. This movement is what causes wind.

It may seem like a complicated idea. But once you have delved deep into the subject of urban wind generator

, you will not only understand how amazing it is. You will also appreciate the labor and genius of people behind the concept and those who utilize the tool to make it richer and more up to date.

The concept of wind power is when the energy that can be found in wind is being converted into electricity. This can be done through windmill or the newer version that is the wind turbine. These two are similar in many ways. But windmills are usually used as a direct power source for machinery, like a grinder for grain. Wind turbines, on the other hand, produces electricity that is to be used off-site.

Both windmills and wind turbines are mounted on a high tower. The main reason for this kind of set up is for these sources to be able to get the most energy. The usual height that is used for mounting these two is about 100 feet and up above the ground. This can give access to faster winds that are less turbulent. Turbines have blades that look like propeller that is responsible to catch the energy from the wind. Typically, there are two or three blades that are mounted on a beam that take the figure of a rotor.

The blade can be compared on an airplane wing. As the wind blows, the downwind side of the blade catches a handful of air that has low pressure. This low-pressure air pulls the blade toward where it is. This causes what is called lift, the scene when the rotor turns. The front side of the blade is also exposed to wind’s pressure. This is called drag. When the lift and drag combine, the rotor spins like a propeller. This turns the shaft to spin a generator and this creates electricity.

Wind turbines can be used in various applications. These can be connected to a power grid or used alongside a photovoltaic system or solar energy source. And these can also be used on stand alone purposes.

Wind generators are great because they allow us to use wind, a natural resource to provide us with energy. Not only do we get to use a renewable resource, they also do not omit any pollution so we will not be hurting our ozone layer. This is especially ideal for people that live out in the country or for island living.

There is an awesome wind generator available called the islomaniac and this wind power generator is completely portable and suitable for small scale use. The convenient thing about this portable generator is that it does not only take advantage of one resource, it takes advantage of both solar and wind power and unlike many systems that are on the market today it is quite easy to set up.

A lot of these turbines weigh under 80 pounds and the dual solar panels are capable of generating 80 Amp-hours per day. At first the initial cost to have a portable wind generator could be a little expensive. However do keep in mind that like most green power systems, the system requires little investment beyond the initial purchase that you make. Just think how great it would be to pay as little as 5 cents a day for energy.

Another convenient thing about portable wind generators is that the standard wind generator normally sits on top of the house and is very hard to move. However the key word in the product is ‘portable’ which means that it is quite easy for you to move it around from place to place. So what better way to help the environment, save money, and have convenience then to invest in a portable wind energy turbine.
