Diy Wind Power Made Easy

In light of the fact that you found this article you are no doubt serious about employing DIY wind power to provide electricity for your home. The wind is a natural occurring phenomena which is actually created by the sun. Residential Wind Turbines have become incredibly popular over the past decade around the world and will continue to rise in popularity as we now complete the first decade of the 21st century.

Residential Wind Power and Solar Panels are on the verge of becoming common sites for homes throughout the world. As people become more aware of the potential for these sources of renewable energy for the electricity they can create, they are simultaneously learning that these forms of natural energy generation also reduce our carbon footprint.

DIY Wind Power and How it Works

Wind power is captured by Windmills or turbines, creating energy that is stored in batteries. The turning of the blade harnesses the energy of the wind and that then creates electricity. Some people refer to this equipment as windmills, some as turbines, but it is the same thing.

Kinetic energy, or physical energy, is created by the turning of the blades by the wind and gathered into a generator. The more wind you have, the faster the blades are able to turn, the more energy you can create. A home Wind Generator stores this wind created energy in a battery which then becomes the source of the electrical power for the home.

DIY Wind Power Will Save You Money

The short answer is yes, absolutely! How much money you’re going to save the plans on quite a few variables including how large your Wind Power Generator is, how much wind you get and how efficiently you capture it. It is absolutely possible to save a substantial amount of money on your electric bill.

DIY Wind Power Systems are very inexpensive to build. For under $200 in materials you can buy everything you need at your local hardware store or large home improvement store. And what makes this project even better is that it is easy to build. Almost anyone can undertake the construction of a Home Wind Power system and do so with success.

How Much Power Will by Home Need

Most homes use on average approximately 100,000 KWH up electricity per year. With that in mind, a Wind Turbine that creates between 5 to 15 kW should do the trick. Of course, the larger the turbine is, the more energy it will collect from the wind. It is even possible to create enough wind power that you not only completely cover your utility bill but you can also sell any unused electricity back to your power company and make some money from them.

The only down side of Homemade Wind Turbines is that they can be noisy. If properly maintained they are not exceptionally noisy. When the wind blows, the movement over the blades creates a whistling sound. Improperly cared for parts will make extra noise as does any moving machinery. Keeping the properly maintained and oiled is extremely important for minimizing sound. It is also a better option to build your turbine out of PVC rather than wood as wood will not hold up nearly as long.

If you are committed to the idea of generating your own power, DIY wind power is an excellent option. Easy to do, inexpensive to build it is a very doable project for the average homeowner. You will find it to be a very rewarding endeavor both in the short and long run. Save you and your family money and do your part to save our planet. It is a win-win energy option.

Could the wind turbines be any louder & be any taller?

Has anyone seen or HEARD the big noisy wind turbines that have been going up in Ohio and other Midwest states? They are so huge and loud. Big corporations slip in quickly & pay unsuspecting farmers to use their land. The corps. get their big tax break but never have to use, repair, or take down the awful things.
Gore and his fear tactics make me sick!

I like how the previous answerers did not mention having actually seen/heard the turbines so I must assume they have not.

I have seen and heard the turbines in Northwest Ohio and I agree with you. I would much rather live next to a coal plant than a wind turbine. I think anyone who has been near one would agree. They are so loud. I would prefer breathing in fumes than having to listen to the turbines endlessly.

In reality I would prefer to live near a nuclear power plant. I already live with in 30 miles of one so moving closer would not bother me. Nuclear power is the most efficient, several EU countries already use over 80% nuclear power. It is safe and efficient.

How Does A Wind Generator Work?

What is Wind Energy?

You may be surprised by the following fact: wind is a form of Solar Energy. It is produced by rotation of the earth, the uneven heating of the atmosphere by the sun, and the irregularities of the earth’s surface.

Wind flow patterns are modified by vegetation, the earth’s terrain, and bodies of water. Human uses this wind flow, or motion energy for many purposes such as flying a kite, sailing and generating electricity.

The words wind energy  describes the process by which the wind is used to generate mechanical power or electricity. A  turbine converts the kinetic energy in the wind into mechanical power. This mechanical power can be used for many specific purposes (such as pumping water or grinding grain) or this mechanical power can be converted into electricity by a generator.

So how does a wind turbine generate electricity? It is the opposite of a fan. Instead of consuming electricity, it makes electricity. When wind blows the blades of the turbine, it turns the blades and spins a shaft which is connected to a generator thus making electricity.

Types of Wind Turbines

There are two main Types Of Wind Turbines: the vertical-axis turbine, and the horizontal-axis turbine. Horizontal-axis turbine is more practical and popular so we will only talk about it here. Horizontal-axis  turbines usually have two or three blades. These three-bladed  turbines are operated “upwind,” which means the blades are facing into the wind.

Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger turbines are grouped together into Wind Farms, which provide bulk power to the electrical grid. Single Small Turbines that below 100 kilowatts are used for homes, water pumping or telecommunications dishes. Small turbines are sometimes used in connection with diesel generators, batteries, and Photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available.

how does a Wind Turbine Work to create electricity?

generally Wind Mills have turbines that work the same as a dynamo based on the principle that “when ever there is a change in the magnetic flux linked with the coil an emf is induced in it”,when wind blows on the blades of the Wind Mill it starts rotating in winds direction. it is connected to a shaft with the windings of metalic coil around it .the coil is placed in the magnetic field,due to the magnetic field there will be a flux linkage & on moving the shaft with coil the flux changes and current is produced.

Wind Turbines at home

Domestic Wind Turbines are sprouting up everywhere now mainly because people are beginning to see tangible benefits of installing them. Homes as well as businesses adopt this technology as an alternatively source of energy that is not only green, but everlasting. With so much uncertainty around us such as fluctuating energy costs and financial turmoil, it has become necessary now to look at Renewable Energy Sources such as domestic wind turbines even for homes.

Benefits of domestic wind turbines

The advantages are obvious. Apart from helping businesses and families save on utility bills every month, the use of Wind Power reduces our reliance of fossil fuels. Wind energy is free whereas oil is not, so electricity generated from burning of fossil fuel is subjected to fluctuations of oil price. Furthermore, the burning of fossil fuel emits heat and carbon dioxide which contributes to global warming.

Domestic wind turbines used to be very bulky and need a large space for it to be installed. Not anymore, there are installations that can be done on roof tops and take up zero land area. Although most of the time, the use of Turbine will not totally eliminate the need to rely on power companies, it is still worth the effort. Some households combine the use of wind and Solar Energy for a complete renewable energy solution.

Costs and availability of components

Domestic wind turbines do not costs thousands of dollars to be installed. In fact, you can have a DIY windmill for less than $200. This is possible because many of the components needed are available now at your local hardware store or on the internet. What you really need is a step-by-step guide to help you build your first Wind Power System.

Is your house suitable for wind power system?

If you have land space of an acre or more, it is perfect for such systems where you can install bigger Wind Blades for increased power generation. But as I mentioned, you can still install smaller ones on rooftops.

The availability of wind, obviously, and wind speed is crucial for efficient power generation. You can find out the wind speed in your area by doing a quick search on Google. Generally, a wind speed of 10 miles an hour or more is sufficient.

George Tho is a DIY enthusiast. Read his review on a complete guide on how to assemble domestic wind turbines using less than $100 even if you are a complete DIY novice.

Little Alien Hobbit finds a friend in a boy! What 1980s movie is that? Wind Turbine Park California?

I am looking for a movie which came in TV around the 1980s ( not later than 85 ), about a boy, a loner who settles with his family into a new home and school somewhere in California. And one day a little alien Hobbit / creature crash lands and befriends this boy. In their attempt to sent him back, they have to evade the authorities and other people.

Mac and Me (1988)
starring Christine Ebersole, Jonathan Ward, Katrina (Tina) Caspary, Danny Cooksey
IMDb synopsis:
A Mysterious Alien Creature (MAC) trying to escape from NASA is befriended by a young boy (Jade Calegory) in a wheelchair. Elsewhere, the young alien is being sought by his parents.
Here are the movie trailer and Part 1 on YouTube:

This IS your movie! You can see the wind turbines at @6:30:

Though I hate to use the word, “Mac and Me” definitely is a ripoff of “E.T.: The Extra-Terrestrial”, which in turn was ripped off by “Nukie” (1988)!

Wind Turbine Energy To Heal The World

Environmental issues have become essential in our day to day life. Our world is being destroyed, so we need to take some action now. Using Renewable Energy Sources can be a wonderful option to do so. Wind and Solar Power are some of the sources for additional energy supply.

Wind turbine energy kits for domestic use are getting more popular these days. They are quite easy to install and really affordable for any householder. Commercial and larger wind turbine energy systems can be too expensive for residential use. That is why DIY Wind Turbines are an outstanding opportunity to reduce your ecological impact on the environment and save some money. Many DIY windmill constructing guides are available online. These manuals have great information about how to Build Your Own Wind Turbine energy system or how to recondition free forklift batteries for your windmill. They are quite cheap and the can provide the perfect assistance on very stage of the building process.

Residential Wind Turbine energy systems offer many advantages over the regular electricity supply.  First of all, wind is everywhere. I may blow slow or quite fast, but it is always there. There is no way we could eve run out of wind.

As the sun, wind is a renewable energy source, so it is completely environmentally friendly and much better than fossil fuels, because wind turbine energy does not generate any pollutants. It is known that 1% to 3% of the energy provided by the sun turns into Wind Power. This is about 50 to 100 times the amount of energy obtained from plat life and biomass over the entire planet.

The installation of a wind turbine energy system is much simpler than Solar Panels setup. Besides, Homemade Wind Turbines are smaller and need less space to be placed on. In fact, their size is perfect for a roof in a residential property. In order to meet legal regulations, it is essential that you get the established permission before you install the turbine.

Wind turbine energy can supply your electricity requirements and save you almost 80% of your electric company bill. What is more, you will never have to worry again about the electric company energy supply during a fierce storm or bad weather, because you will be able to power your home in an independent way. Most of The Wind Turbine energy systems have a set of batteries to store the exceeding energy generation and use it when required.

Regarding the production of wind turbine energy, much more advanced technologies have been developed. That is the reason why these Windmills can generate energy even when the wind does not blow so strong and direct where it is needed in an efficient way.

Even though homemade Wind Turbine Efficiency does not reach 1000 KW capacities, your domestic electrical requirements can be totally covered with it. Wind turbine energy systems are an exceptional possibility to save some money and they are also a great opportunity to use renewable energy sources to supply your routine necessities.

how much money does a 2.5 MW wind turbine make per day?

assuming 100% effeciency and 6 cents per KW/H

In this problem, efficiency is largely irrelevant, as the turbine is rated on *output* electrical power. Efficiency is (electrical output power)/(mechanical input power) If it’s a 2\.5mw Wind Turbine, its output capacity is 2.5MW regardless of the input power.

However, you will need to consider capacity factor. The capacity factor is the ratio between the average output power of a generator, and its maximum capacity. Because the wind does not blow at a constant rate, a wind turbine does not have constant available prime-mover power. It cannot generate more than its rated power, but it can generate less. Estimates of the capacity factor of wind turbines range between 7% and 30%.

Then, you must consider whether the income you are calculating is net or gross. For the wind turbine to be considered to be “making money” in isolation from the overall generation portfolio, one must presume it is connected to one of the deregulated electrical grids as a market participant of some sort. Normally, then, it will be subject to some contract whereby it has to pay for the use of the transmission system that it connects to, and may in addition pay a surcharge for any losses or congestion that it causes. It will also generally be paying either a land-use fee to the landowner where it is situated or, if owned by the land owner, and aggregation fee to the operator of the collector system to which it is connected. Transmission usage fees are usually based on a proportion of the power generated, while land-use fees are usually a flat rate.

So your calculation will be:
C=Capacity Factor
T=Transmission access charge($/MW-hr)
L=daily land-use fees ($/day)

Net income per day = C * 2.5MW * 24hr/day * ($60/MW-hr – T) – L

Making Your Own Home Turbine Wind Power

Imagine your neighbors told you they were going to produce their own home turbine Wind Power? Would you be shocked? Well, very soon that may be the norm. As we gain interest in making Alternative Power, we increase our understanding of making our own home turbine wind power. Lately, it has become so popular that a number of step-by-step instructions are available on the Internet, where in a short space of time you can learn to build your own home turbine wind power from scratch.

Before attempting to build any home Wind Turbine, it is best to do your research, such as on the various blades designs, what type of dynamo to buy, and how to put all the components together to make a working Home Wind Turbine. While all the information can be found freely on the web, it is better to buy a complete step-by-step guide, with all the information in one place and easy to find. Another advantage to a guide is that it comes with free customer support if you need any help or assistance.

All guides are not the same, so investigate each guide thoroughly before pulling out your credit card. This can be as straightforward as reading customer testimonials and reviews, or contacting the seller. Things to take note of when reading reviews are:

1 – How simple the instructions are to follow

2 – Quality of customer support

3 – Quality of the finished home wind turbine

So what components make up a home wind turbine? And what tools will you need to complete the build?

A Home Wind Turbine consists of the following components:

The motor:

This is one part you are better off purchasing. Various motors or dynamos can be sourced over the Internet, but make sure you buy a dynamo that operates at low speeds. The motor requires the most maintenance and should be lubricated regularly to improve to lifespan an performance.

The charge controller:

The charge controller is there to ensure the batteries are not over-charged. Although you can do without it, your batteries lifespan will then be dramatically shorter.

The batteries:

To ensure power is available all day long, even when there is no wind, it is best to have batteries to store excess power. There are a number of batteries to choose, the best being 24 volt deep-cycle batteries that store the charge for longer and are big enough for you to scale up your system with.

The inverter:

Before the stored energy can be used to power your home, the direct current needs to fed through an inverter, where it is changed to alternating current. There are various types of inverters to choose from, each with their own voltage, but your power needs will help you determine which one to buy.

The tower:

With home turbine wind power the tower is the structure supporting The Wind Turbine. It can be made from any pole, and supported by guy ropes, and its height varies with the area’s wind conditions. For urban areas, its best to fix the tower on the roof for the turbine to catch as much wind as possible.

The tail:

The tail is fixed at the back of the dynamo and is responsible for keeping the turbine facing the wind.

The blades:

These are the rotors that catch the wind and spin the motor to produce power. They can simply be shaped from quartered PVC piping, but it can be little weak for very windy conditions. So it is beneficial to take the time to make them from tough, lightweight timber, such as balsa wood. The blades are generally about 8 feet in diameter so a decent sized workspace is essential.

The tools:

Like most DIY projects, the basic tools needed to make your own home turbine wind power are screwdrivers, a drill, a saw and some wrenches.

So what are the benefits of making home turbine wind power?

1 – The massive cost savings: When compares to getting a commercial Small Wind Turbine, making your own will cost you less than a tenth of the price.

2 – Lower electricity bills: Making your own Renewable Power results in lower electricity bills and tax incentives from government.

3 – Improved knowledge: The expertise you gain from learning to source the components to putting a fully functional home wind turbine together is priceless. Also, if you enjoy it so much you could make a business from it by building Home Wind Turbines for your neighbors and even your family and friends.

If producing your home turbine wind power was something you have always wanted to do, then there could be a better time to learn. So, start your new home Wind Turbine Project today, and enjoy the benefits that cheap power and knowledge bring.

Wind Turbines facts

Have any studies been done on the negative externalities of wind turbines?

I am curious to know what effect the turbines will have on other aspects of nature. I am not talking about people not liking the view or of birds and bats dying unless it turns out that some species or another is drawn to getting killed by these. The fact is that in this universe, nothing comes without cost. Sapping the energy of the wind decreases the airflow over the land; the question I have is whether anyone has identified any negative impact on the downwind environment because of Wind Farms.

There have been some minor studies about this impact, but no significant ones to the extent of my knowledge. A google search yielded this study by some Stanford U students:

http://www.stanford.edu/group/peec/cgi-bin/docs/systems/research/Investigating%20the%20Effect%20of%20Large%20Wind%20Farms%20on%20Energy%20in%20the%20Atmosphere.pdf

Realize though, that a Wind Turbine is no taller than your standard city skyscraper, and usually not too much taller than trees. The effect of (a) wind turbine(s) on wind and air flow is comparable to the effect of these things (trees, buildings etc). I suppose at the very worst we’re talking about a slight increase in surface friction for air flowing, and therefore a decrease in surface wind speed, but the effect is probably marginal at best. If a forest existed on the field prior to the Wind Farm, the effect would likely be comparable to this. Regardless, the area that would be impacted by this would be minimal (a few kilometres downwind at most, and a few hundred feet in altitude at most) since surface winds are fueled by air moving at much higher altitudes than the wind turbines typically reach.

How to Build a Simple Model of a Wind Turbine

Some people enjoy taking matters into their own hands and instead of paying for a Wind Generator, they prefer to create a project of their own and build one. Building a wind generator from nothing is actually not as difficult as one may think. In order to build a simple model of a wind turbine, you will need to go to a shop with basic power and hand tools, and have some degree of dedication.

Large Wind Generators of 2000 Watts and up are a major project needing very strong construction so prepare yourself in advance for the time and effort if that‘s what you want to do. But the smaller ones in the 700 to 1000 Watt, 8 to 11 foot range can be built with not too much difficulty.

In fact, it is highly recommend that you tackle a smaller wind turbine before even thinking about building a large one. You will need to be able to cut and weld steel, and a metal lathe can be handy although to make life easier on yourself you could take into consideration hiring a machine shop that turns brake rotors to do some small steps for you.

In most locations, gentle winds (5-15 mph) are the most common, and strong winds are very rare. You should try to make a sturdy machine that will produce good power in low wind speeds, and that will be able to survive high wind events while still producing maximum power. Remember, the power available in the wind goes up by a factor of 8 as the wind speed doubles.

Other critical factors are rotor size and tower height. The power a wind turbine can harvest goes up by at least a factor of 4 as you double the rotor size. And making a tower higher gets you above turbulence for better performance and increased power output. Putting a wind turbine on a short tower is like mounting Solar Panels in the shade it simply just does not make any sense, doing so, does it now.

Before you jump into something serious like building your own wind turbine, do your homework. Some things work and other things will not work. You can therefore save hours and dollars by learning from other people’s successes and failures.

Things You Need To Know To Build Your Own Wind Turbine

When it comes to ecological matters, there are many options to power your home with environmental friendly energy resources. One of them is the power that you can obtain from the wind. However, these ecological gadgets may be a little expensive and too large for domestic use. That is why Homemade Wind Turbines are becoming more and more popular these days. Plenty of easy-to-Build Wind Turbines systems are available on the market. Besides, they are quite affordable, as you only need to purchase the blades and the shaft. For less than $150 and a little time and effort you are ready to Build Your Own Wind Turbine and reduce your impact on the earth’s ecosystems.

Before starting to build your own wind turbine, you need to become familiar with the components of a wind turbine. Three mains parts are necessary to get this windmill to work: Rotor blades, a shaft and a generator or a transformer.  Rotor blades are usually made of plastic or wood, and the most expensive can be made of aluminum. They are intended to be very lightweight, so the wind can stir them easily.  The rotation of these blades is quite important because more movement leads to more rotational energy and more power to be used.  A rotor holds the blades and absorbs the rotation dynamics generated by the blades. This rotor is attached to The Wind Turbine shaft, so they can spin together and power can be transferred to the generator.  An electric generator or transformed is required when you build your own wind turbine. As power is directed through the shaft, the generator captures it and turns it into electricity. Some Wind Turbine Systems provide batteries to save extra power. Electrical wires feed into a battery, where the energy can be stored. This way you can supply your home with renewable resource energy anytime and reduce you impact on the environment.

It is strongly recommended that you check the wind patterns in your area with a little online research before installing your wind turbine. You should be able to determine the average strength and speed of the winds that blows over your place.

It should be placed in order get a considerable amount of wind, so it can work properly. The blades should be facing the right direction, so they can take as many winds as possible. You should take into account that 45 degrees or more will stop any possibility of power generation.

To get to build your own wind turbine will mean a reduction in your ecological footprint. It will also save you a lot of money, as you will not buy a commercial turbine and will do it yourself. Besides, the electric power company bill will be highly reduced, as many of your home appliances will be supplied by your homemade turbine. You can have major savings in your domestic budget and a environmentally friendly house with your small scale Homemade Wind Turbine.

How do you feel about the act of tera-forming on earth?

The art of moving and shaping nature in order to constuct a better place for mankind. Such as: a city wanted to build itself with its local river in mind, and decided to carve water canals in a twisting meandering way throughout its residents and businesses locations. The city was beautiful and everyone had access to crystal clear water canals. Such as: a large circumference tube was raised higher and higher into the atmosphere with a horizontal opening at the top which could catch the earth’s jet stream air current and channel the air to earth where it was used For Wind Turbines and for the substution of fossil fuels in that it could be used to transport people and items, such as todays bank-teller tubes but on a much larger scale. Such as: Mountains were scooped up and placed into the deserts so that the rainclouds could therefore go to the desert area, since before they had been blocked by the mountain ranges. Thereby turning the deserts into farmland

Its a very interesting idea. Scientists are always trying things out before thinking them through carefully. Its sound good, but there are always consequences when manipulating the forces of mother nature. Some times the consequences can be quite devastating.

It does deserve to be thought through.

Another Reason to Build Wind Turbines – if You Want a (better) Job

If you gain experience in Building Wind Turbines for your home, it won’t only reduce your power bills and maybe get back some money from the power company like in California, but as a recent survey shows there is a serious shortage of qualified Wind Turbine technicians across the country!

 We just read the results of Frontier Pro Services’ survey of approximately 75 Wind Farm operators in the United States. This reveals the aforementioned problem, and that this is an industry-wide situation and a serious threat to current Wind Farms.

Apparently manufacturers also face similar resource struggles because the services offered under warranty – like gearbox lubrication and general oil changes – prove to be a challenge for maintenance teams caused by their limited resources. These operations are essential in order for the turbines to continue generating electricity.

The most common failure is gearbox related and it could be prevented with regular and high quality maintenance thus avoiding the very costly repair of the already broken parts. These can total 15-20% of the price of The Wind Turbine itself. Experts say that a $1,500 bearing fails unnoticed it can cause severe damage to the company including revenue loss and the need for a replacement gearbox with the price of $100,000!

Gearbox failures account for the largest amount of downtime, maintenance, and lose of power production.  These costly failures can total 15-20% of the price of the turbine itself, making wind turbine and gearbox maintenance a high priority.

You can find out How To Build Wind Turbines (in a smaller scale compared to industry sizes of course) to power your home only with the help of the wind, lowering your bills with 80% or sometimes completely eliminating them.

Save lots of money by using wind

As fuel prices continue to rise, so do utility costs. The cost of maintaining the need for electricity is called by the escalation of hours, and people are more In addition to finding suitable alternatives to conventional energy. Renewable Energy booths as the most appropriate alternative, with wind energy option is the most popular and growing fast. In addition to highlighting the skills, Wind Power differs in its cost-effectiveness and potential savings.

Between 2000 and today, the production of energy wind has increased four times. Wind energy is increasingly popular because it is clean, renewable, easy and inexpensive access other forms of renewable energy. Wind turbines have emerged in the world that people are increasingly installing do-it-yourself wind and take out the network. Imagine considerable savings compared to getting a commercial system installed energy renewable!

Although wind energy accounts for only 1% of global consumption of Alternative Energy, some countries have made great progress. Denmark uses wind turbines to 19% of their electricity production, Spain, Portugal and the use 9% and Germany and Ireland use 6% each. As more people start using wind turbines and technology develops, the cost of acquisition wind is down. This is great news for those looking to save money by using alternative energy.

Your electricity bill can be reduced by half immediately by installing a single Wind Turbine to produce half of its energy needs. The amount of electricity you need to determine the type and size of the turbine, you will need. To save even more, you can Build Your Own Wind Turbine from auto parts standard. Do you get excited now?

A turbine house can be mounted on the ceiling or on a separate tower, which can be concrete. Your property can contain as much as you want or need, provided you have the space. In fact, several wind turbines home can cost less than commercial turbine. If you can build few 5-10 foot Wind Turbine Blades, of course, it can feed the whole family!

In addition to saving on utility bills and installation cost and maintenance free solution, you can also save money by selling energy to the company utilities. In many countries, any excess energy produced by wind energy system can be sold to the company electricity, to make payments to almost zero. There are also government tax incentives available for qualified to switch to Alternative Energy sources.

If you were not sure before, you should be safe now. Energy Wind power is the way forward. This is the best alternative energy source to protect the environment and ensure a lifetime of savings.

which is an advantage of using wind rather than combustion of fossil fuels to produce electricity?

Also for another these describe a drawback of using wind rather than combustion of fossil fuels to produce electricity if you answer my question please answer two questions involving A or B or 1 and 2, but you need the advantage and disadvantage.Thank you !!!!!!!!!!

After considering all the factors that you will find that there is really no advantage. After the energy used in the manufacture of parts and repair of wind turbine, you will consume more energy than it will ever produce. same problem exists with cells Sun. There is an abundance of fossil fuels and land is always more. It is part of the natural cycle of the planet. H2O + CO2 + sun creates oxygen and hydrocarbons (plants). So until we have the sun, we have the energy. When the sun goes away, too.

Dry Type and Liquid-Filled Transformers: A Quick Comparison

Transformers under load generate heat due to winding (copper) and core losses occurring during operation. There is an ‘acceptable’ temperature rise for transformers used in power applications, and this can even limit their size. This acceptable temperature rise is directly related to the limitations of the transformer materials; safety regulations; or component parts in close proximity that may have high-temperature reliability problems.

High temperatures can damage the winding insulation; the heat generated from core and winding losses must thus be dissipated. This dissipation can be achieved with a combination of radiation and convection from the exposed surfaces of the transformer. Dry type power transformers up to several hundred kVA can usually be cooled by convection or even by fans. Power transformers can also be immersed in coolant liquids – which can range from mineral oils to silicone-based oils or ester-based vegetable oils. .

Based on the type of cooling used, transformers are thus classified into ‘dry type’ and ‘liquid-filled’.

Liquid-Filled Transformers

1. Oil-filled Transformers
   Oil-filled transformers primarily use mineral-based oil and cellulose paper (Kraft or Aramid) in their insulation systems. This proven combination exhibits outstanding thermal and dielectric properties at a relatively low cost. So popular and effective are these units, that all other transformer designs are judged in relation to them. They are still unparalleled in terms of purchase cost, among all the options available. The inherent weakness of a mineral oil-filled transformer, of course, is flammability; which is why oil-filled transformers are usually restricted to outdoor installations, or indoor installations that have elaborate means of fire protection.

   Typical Applications:
   Oil-filled transformers, thanks to their lower purchase costs, find applications in literally every sort of power distribution. Of late, the awareness of the fire risks associated with mineral oil-filled transformers has created a movement towards safer alternatives that use non-flammable, biodegradable liquids, or even dry-type transformers.

2. Non-Flammable Liquid-Filled Transformers
   Polychlorinated biphenyl (PCBs) were produced in large quantities starting as early as the 1930s, in response to the electrical industry’s need for a less flammable substitute for mineral oil as a cooling/insulating fluid for transformers. Several industrial incidents, however, brought the toxicity of PCBs to the fore. As confirmed organic pollutants, PCBs were banned by the late 1970s. A number of alternatives have since surfaced – major ones being silicone, perchloroethylene, high temperature hydrocarbons, and mixtures of oil with perchloroethylene. The first high molecular-weight hydrocarbon-based fluid (HMWH),  was introduced in 1975. This fluids possesses similar dielectric properties as mineral oil, provide remarkable levels of fire-resistance, and do not have undesirable environmental fallouts.

   Typical Applications:
   Non-flammable liquid-filled transformers can be installed indoors and outdoors, close to buildings, walkways and rooftops. Usually, no additional infrastructure is required to address issues like fire safety.

1. Biodegradable Fluid Liquid-Filled Transformers
   Animal fats and vegetable oils offer substitutes that are significantly less harmful to the environment than petroleum oils. However, vegetable oils were not used in transformers for a long time; a fluid which could be stable in the transformer environment and available in the required quantities was simply not available.

   Transformer manufacturers have since worked on transformer designs that utilize Vegetable Oil-based dielectric fluids. Comparable in size and electrical performance to conventional liquid-filled units, these transformers are filled with the less flammable dielectric fluids mentioned above. The immediate advantages of biodegradable fluids are clear: higher fire and flash points, thus reducing flammability concerns. The other, and perhaps more long-term advantage, is the fluid’s biodegradability: it has demonstrated high environmental assimilation (over 95% in less than a month) – and it has the virtue of coming from a toxin-free resource.

   Typical Applications:
   Biodegradable fluid liquid-filled transformers find application in wind turbines, and other indoor and outdoor areas of heightened environmental and safety sensitivity.

Dry Type Transformers

1. Vacuum Pressure Impregnated (VPI) Conventional Dry Types
   Dry type transformer construction uses high-temperature insulation that exceeds the ratings of cellulose or ‘O’ and ‘K’ class fluids. Modern conventional dry type transformers feature insulation systems comprising carefully coordinated high-temperature (220′C) materials coated with a high-temperature, moisture-resistant polyester sealant. On better quality premium units, the polyester sealant is typically applied with a vacuum pressure impregnation (VPI) process. Units built in this fashion have exhibited high resistance to most chemical contaminants. Dry type transformers are generally rated up to 30MVA; performance under overload is demonstrably limited, but the addition of cooling fans can usually help augment this.

   Typical Applications:
   Dry type transformers have been used effectively in diverse commercial and industrial environments for decades; at ratings exceeding 15 kVA. Appropriately designed and installed, VPI units can even be an exceptionally economical choice in medium voltage distribution (15 kVA, 10 MVA ratings), even with the inclusion of installation costs. Because of reduced fire risks, these transformers have been used successfully in special applications where the public are in close proximity, such as underground tunnels, residential apartments, oil rigs and more.

2. Gas-Filled Dry Types
   Gas-filled dry type transformers are designed for applications where low flammability is a vital consideration. N2, C2F6, and SF6 gases are the ones used in these designs, providing a dielectric medium that is external to the windings. Apart from being the dielectric medium, these gases also act as the thermal medium to transfer heat from windings to tank walls. Gas-filled transformers are an alternative to dry-type construction with fewer fire and contamination risks. 

   Typical Applications:
   Gas media have somewhat limited thermal capabilities; and gas-filled dry type transformers usually do not exceed 3750 kVA (C2F6) or even 2000 kVA (N2). Their design also makes them considerably larger than oil-filled units – anywhere from 20% to 30% bigger. Properly designed and installed gas-filled transformers can operate in any environment and remain truly non-flammable. They are commonly installed in dry-docks to provide local power for shipbuilding. Dry-docks (including transformers) are eventually flooded to float the ship away from the construction site.

3. Vacuum Pressure Encapsulated (VPE) Dry Types
   Military shipboard use is an exacting requirement, and VPE dry type transformers were developed to meet these needs. VPE transformers are similar to VPI transformers, but employ a resin made of silicone instead of polyester. The VPE method includes several dip processes to encapsulate the coil assembly; the coatings are then cured in an oven. The resin coating in the VPE design is also typically thicker, sometimes by as much as a factor of four; as can be expected, the thermal classification of the insulation system is markedly different for the military than for commercial applications. VPE transformers are more resistant to harsh and wet environments than VPI type counterparts.

   Typical Applications:
   VPE dry type transformers typically find applications in very harsh indoor and outdoor environments. VPE technology allows the transformer to be highly resistant to humid and caustic environments, but carefully designed enclosures are still a must.

4. Epoxy Coated Dry Types
   Epoxy coated, or ‘epoxy shielded’ dry type units offer the benefits of better environmental protection, minimal noise, high basic impulse levels and better short circuit strength than cast coil types. Epoxy shielded transformers are also usually less expensive, flexible, smaller and lighter. There are typically two variants of epoxy coated transformers – in one, a VPI dry-type is given an overcoat of epoxy varnish; in the other, the epoxy varnish is used as a complete replacement for the polyester sealant.

   Typical Applications:
   Epoxy coated transformers can be ideally suited for environments that may be polluted with acids, alkalis and chlorides. They are also resistant to the effects of Salt Water and high humidity, thus finding numerous applications in areas which concentrations of these problems.

1. RESIBLOC Epoxy Cast Dry Types
   Unlike conventional VPI dry type designs, RESIBLOC  Epoxy Cast dry type transformers do not use insulation papers in the windings. Instead, pure epoxy resin reinforced with glass fiber rovings are wound directly with the wire. Winding processes controlled by advanced electronics also ensure even distribution and high levels of precision. Aluminum/copper foils are used for the low voltage winding; and circular (or rectangular) copper conductors with glass-fiber reinforced epoxy resin insulation are used for the high voltage windings. The completed winding block is then ‘cured’ in a specially designed oven under rotation. This process enables cast winding production without molds or vacuum. As in most cast epoxy units, the dielectric material on the interior winding is the epoxy itself. RESIBLOC transformers are reliable, environmentally safe, offer extreme fire resistance, have high short circuit withstands, and can be exposed to extreme conditions with minimal maintenance.

   Typical Applications:
   RESIBLOC? transformers often find applications in energization, ovens, or traction; they are commonly found in the railways, marine propulsion and distribution, in the nuclear energy and Windmill Power sectors, and in the mining industry.

1. Epoxy Cast Dry Types
   The primary and secondary coils in epoxy cast dry type transformers are usually wound with copper conductors, pre-heated and placed in a mold which will then be filled with de-gassed and mixed epoxy under vacuum. The molds are then cured in special ovens to allow sound, void-free casting. The result is a winding design that is void-free, hermetically sealed, and with a smooth exterior finish.

   Typical Applications:
   Epoxy cast dry type transformers are used inside buildings and tunnels, on ships, offshore platforms and cranes, food-processing plants, and more. They are often combined with primary and secondary switchgear and distribution boards, to form compact substations.

Why are Wind Turbines Places on the Ground and not up in the air?

My questions is more technical than the above, but I didn’t have enough room.

I did see a show on discovery channel that had a prototype balloon type wind balloon. It would be teathered to the ground and send electricity back down as the balloon spins.

Here is a diagram of what it did

http://dvice.com/pics/09_1_turbine.500.515.jpg

This is the real thing

http://hillpointenergy.com/windblog/wp-content/uploads/2008/08/magenn.jpg

They proved it could be done but it was inneficient, it would take more maintinence than the Turbine because the gasses inside the balloon, over time would escape and it would begin to fail.

At the moment wind farms are easier to maintain and produce. They do work, so theres no reason to change at the moment. The main problem is airspace, more planes in the air, it would be a big challenge to stay safe if your flying in these areas.

Wind Turbines advantages

Description of Home Wind Turbine Technology

I am sure that many of you might not be knowing about the Home Wind Turbine technology. However, the Wind Turbine Technology is making a new wave nowadays due to its’ numerous advantages and implications. Companies are constantly working on new technology in Wind Turbine. Wind Turbine Energy comes second only to Natural Gas as a source of new electricity generation in the United States.

If you live in a heavily developed area, then it is recommended that you use your home wind turbine just to reduce your energy bill and carbon footprint a little – it is unlikely that you’ll have access to enough wind to do much more than that. It’s highly recommended that you only invest in one of the smaller roof-top wind turbines if you live in one of these areas.

How will Home Wind Turbines affect your finances? Well, this will of course depend on how much electricity your wind turbine is turning out, how much you’re paying for it, and how much you pay on your electricity bill to start with. If you do not have a large electric bill to start with, then you should be able to save quite a bit of money, since you’ll also be able to sell back energy to the grid on high-wind days, and make that money back from the electric company.

The elevated home wind turbines will come with a tower that is between 80 and 120 feet tall towers. The towers help The Wind Turbine get access to stronger winds that are not broken up by structures and/or trees on the ground. It is unlikely that this will be enough to fully take over the power consumption of your home, so it is only a good idea if you’re looking to reduce your carbon footprint by using less coal-powered energy.

A number of states have been producing wind resource maps and collecting data which could be used by farmers to determine the potential for Wind Power Generation on their land. Home wind turbines are increasingly being used today and have a great potential in future!

WHAT DO YOU KNOW ABOUT Wind Farm AND WIND TURBINE?WHAT ARE THEIR ADVANTAGES?

Non_CONVENTIONAL USE OF WIND ENERGY CAN BE USED FOR ENERGY PROCUREMENT.
A wind farm is a group of wind turbines in the same location used for production of electric power.
A large wind farm may consist of a few dozen to several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may be located off-shore to take advantage of strong winds blowing over the surface of an ocean or lake.
Advantage:
1Energy source is wind.No pollution due to burning of rare fuels.
2Effective utilization of land.

3, Not directly affected by solar cycle (Solar Panel issue).
4, Relatively quiet
5. Less expensive installation and generation costs.

Disadvantages
1. Less reliable power output (wind velocity changes)
2. Less power output overall
3. Bird strike hazard

THIS TYPE OF farm is the place where most of the year wind blows with some velocity. Wind turbines are set up in such places to harvest this wind and generate electricity using only the wind energy. This is the most eco friendly method of generating electricity.
