Q&A: What are the basic element in wind energy conversion device?
Question by farhana: What are the basic element in wind energy conversion device?
I have to build a wind energy conversion device for my design subject. However, I can’t use toothed gears, gearboxes, energy storage systems (e.g. flywheels, batteries, pressurised fluids, etc), rolling
element bearings and existing (pre-made) fan impellers.
So I need rough ideas on what are the things that can replace those items which can make the device moving.

Your basic design goal is to “Build a Wind Energy Conversion Device”. This is a broad goal as it does not specify if the end result needs to produce electrical or simply mechanical energy.
You are limited as you cannot use any rolling element bearings. This can cause a problem for horizontal wind turbines. To avoid this, you can use a vertical wind turbine similar to the following. http://www.ecofriend.com/entry/pacwind-vertical-axis-wind-turbine-at-home/
The curved blades will “catch” the air flow no matter what the wind direction is.
To avoid the use of rolling element bearings, a vertical wind turbine can be supported at the bottom. Ensure both the spinning shaft and the housing are smooth and greased. Supports higher up will also be needed to keep the turbine level. These can be holes cut out of the frame which are close to the spinning shaft.
To transfer the power, use a pulley and belt system. This won’t violate the toothed gear rule. You will incure some efficiency losses as the belts and pulleys will slip.
on the other side of your pulley, you can hook it up to a small generator to generate power continuously as the wind blows, or you can attach if to some mechanical device to provide mechanical power. Just ensure the initial start-up torque isn’t too large.

Wind has been considered as a downside of regions, a factor that conspired against urbanization, highlighting destructive power of the wind. But more recently, technology has provided a whole new outlook on the wind. Regions with steady regular wind have proven to be the most suitable ones to produce a new way of cheap and clean energy: wind energy.Wind energy can be “harvested” with the use of wind turbines. Wind turbines are roughly structures with big propellers that take advantage of the constant movement of the propeller, generating energy. In the same way mills took advantage of wind, typically to extract water from the soil, these new wind turbines generate electricity in an efficient way. Technically, it can be said that they convert the free everlasting kinetic energy of the wind into electricity. No chemistry is involved, because it is simply an ingenious device that transforms energy into usable ways. A Wind Turbine Energy consists mostly of three main components: the rotor blades, the shaft and the generator. A lot can be said about the design of the blades. They need to be aerodynamically shaped, so as to make the most of the wind, with the least loss of energy. This includes careful consideration of the materials blades are made of. At first, wood was the preferred material. Later on light metals were used, like aluminum. The most suitable is carbon fiber, an extremely light material, amazingly resistant. The shaft is connected to the rotor. It transfers the movement to the rotor, which has one end attached to a regular electric generator. Here is where the electric energy is produced. This is a very simple, yet very effective mechanism. Electricity will be produced as long as the blades spin.The generator works using the properties of electromagnetic induction. The core of the generator is made of magnets, that when moved constantly close to a conducting material -copper wires, most typically-, produce a difference of electric tension -voltage. Magnets have this amazing property: to release electrons: energy.Windmills are used in areas where traditional wiring is not present, for instance in rural areas. In 1930, 600.000 windmills provided water and electricity to many rural areas in the United States. By 2006, new windmills were developed that could produce up to 4 mega Watts of electric power, enough to supply energy to a small neighborhood with one single mill. The new wind turbines have a completely different design from traditional mills, the axis being placed vertically, instead of horizontally. This new layout helps maximize the power of rotation of the wind. This design is called VAWT. The size of the Wind Turbine Energy mills is highly relevant. The bigger the mill is, the most energy it can produce. The drawback is that bigger structures require bigger parts that will necessary gain in weight. That is why new materials such as carbon nanotubes and glass fibers are so effective when designing mills.

Horizon Wind Energy, LLC, describes itself as the fourth largest producer of wind energy in the world, and built, owns, and operates wind farms throughout North America. It’s got in excess of 25 wind facilities in Eighteen states, such as New York City, California, and also Texas. Previously, the company was known as Zilkh Renewable Energy, LLC, but the name was changes in 2005. The corporation was established in 1998 and has its headquarters at Travis Street in Houston, Tex. This is a subsidiary of EDP-Energias de Portugal, S.A.
It was reported in March, 2011, that Horizon Wind Energy has been generating excellent progress in building of Ohio’s first industrial wind farm. The project will create many jobs and make an important contribution to the local economy: more than 200 workers are involved with construction, and there will be tens of millions of dollars of landowner royalties and property tax payments. The business also has expended about $ 175 million in Paulding County, Ohio and also worked with greater than a 100 community landowners. Vanessa Kellog, Horizon’s Director of Project Development for the Southwest Region, said, ?The landowner relationship is the most important aspect of it,? and says that Horizon performs a great deal of work with education and learning as well as other strategies to outreach The farm contains 55 windmills for electricity that will produce enough energy to be able to power over 27,000 properties.
At the moment Horizon is planning on opening a headquarter in Indianapolis and also to build several wind farm in Indiana which would more or less cost around 2 billion dollars.. The resultant wind farms would be the company’s greatest and will be based at Meadow Lake, White County. The project that will provide 1,000 MW of power each year will need 660 turbine on a 10,000 acres farm. While the blowing wind in Indiana is really a portion of that present in West Texas, in which massive wind plants are being made , the state is interesting as the farms would be nearer to their particular customers.
Last year, Horizon signed a 20 year agreement with the Tennessee Valley Authority to sell 115 MW of electricity from its local Pioneer Prairie Wind Farm. In 2009, the corporation finalized another contract to sell 102.3 MW. This farm can actually power 90,000 homes each year using its 300 MW.
Usually, Horizon consumes between $ 150 and $ 200 million on the 100 MW wind plant. This is actually to cover for land lease and road construction, The majority of the wind turbines for the home utilized by Horizon had been built by Vestas, a Danish company, and they must be transported on unique pickup trucks over sturdy streets. Even while wind turbines is known to be eco friendly it still has a bit of an impact in the environment that is the reason why Horizon is working with Nature Conservancy and other agencies to help minimize the problem. Farm owners generally rake in between $ 4,000 and $ 8,000 each year for each wind turbine, a portion of which is paid as tax. This is because the farmers can really use the power generated because it needs to be sold to utility companies. Horizon’s customers include the TVA, Great River, Direct Energy, and AmerenUE.
Supporters of wind energy wish to generate 20 percent of the electricity required by the United States from wind by 2030. Because the figure at present is at one percent, there’s much area for growth.T. Boon Pickens actually spends millions for this product, simply because he knew that this is a great investment,. He has additionally made substantial direct investments.

Renewable resources are becoming more popular by the day because of the constantly growing gasoline rates, the fact that oil will someday be depleted and the fact that our present energy sources are harming our planet. Whatever the location, one of the best renewable energy sources available is the wind, but what is wind energy precisely?
Wind power is actually the act of utilizing wind produced naturally to make energy which may be used as power. By simply capturing the wind, you can power an engine which can be used as a generator to power the household appliances as well as the heaters. Producing power using wind is easy and could be carried out in small or large scales. In fact today, wind turbines for the home are extremely popular and are being used to power thousands of homes in North America alone. The windier a place is, the more power can be harnessed and used as energy.
There are specific pros and cons to think about in wind power just before building your own DIY wind turbine. One of the advantages of using wind generators for home use is that wind almost is free of charge and can be found all over the world. This is not the same as the oil and other energy sources of these days. An additional advantage of using the wind turbines is that the wind won’t absolutely run out; it is impossible to have a wind power shortage. However, wind power also has drawbacks such as the fact that wind is never constant; several days may have extremely strong winds while other days could be very calm. One more disadvantage of using wind power is that among the biggest turbines that are available today can power just about 400 homes; you’ll need several turbines just to power up a small cities.
So now that you already know some of the wind power advantages and disadvantages you need to be in a better situation to select whether or not wind turbines for the home are a good choice for you. Wind turbines when created with large enough motors can be used to power your whole household together with all of the appliances that you might want. Not only can you produce enough power to use all of your home appliances along with heating your house but you may also be guaranteed to have power even when your city losses power. You will be responsible for your own energy power which will give you much more freedom.
Rather than buying electricity from large power companies, one of the biggest questions that people might ask once they decide to use windmills for homes is the sum of money that will be saved. Upon having your wind turbine set up, the particular power costs nothing at all so the wind turbine cost is simply the only thing that you will ever have to pay for this kind of power. In the long run this will end up saving you lots of money but it will require a small start of fee. The price of turbines will be different depending on how big you need it to be and whether you’re making it yourself or buy one. The best things with regards to making your own energy is that the power companies will actually pay you for your excess energy that will go unused each month based on the location where you reside.
Now that you have exactly know what the wind energy is and how it can be very useful for you and your entire family. The decision really depends upon a personal preference but if you have enough money to afford buying a wind turbine right now, you’ll never need to pay for power again. Most banks are more than happy to help out people who are willing to invest in clean energy methods so your chances of having a loan for a wind turbine are higher than other types of loans.
