Silent Wind Turbine . The Vertical Axis Wind-Power Turbine ( VAWT ) is a new product designed . We started the research on VAWT 15 years ago. Now many of the famous experts the world wide have accepted such new technology and this technology will definitely lead the development of the small and middle size wind-power turbines. Following are the detail features of such VAWT: Safe in operation: Due to the usage of the vertical blade and the force support is of triangle form, the wind force will mainly press on the wheel. So the blades will not be able to fall down, to be broken or to be thrown far away. Noise: The way of the turning of the blades is of horizontal and the design of the blade is of the scheme of the wing of the air-plane, so in operation the VAWT will not make any noise. Capacity of wind resistance: Due to the advantage of the design of the VAWT, the press force the turbine suffered is minimized and as the result such VAWT can stand on the extra strong typhoon of 45 m/s. Space requirement: It needs much smaller working space than other kinds of wind-power turbines. Thus not only saves the space, but also aises the working efficiency. Power curve: It needs lower wind speed for its starting and the increasing of the power is slow and stable. So its production capacity is 10-30% higher than other kindwind powernes. Scope of the wind power needed: Due to the adoption of the new control system, this VAWT is suitable to be used in the wind speed scope from 2.0 25 m …

DIY Wind Power Generators & Turbines – Slash Your Energy Bills and Reduce Your Carbon Emmissions At the Same Time!
Wind power is an excellent weapon for fighting climate change because wind generation produces no carbon emissions at all. When you consider that every unit of energy generated by wind, is a unit of energy free of carbon pollution, wind makes sense. Producing just 10 per cent of electricity from renewables could cut carbon emissions by 2.5 million tonnes a year.
Small wind-electric systems can provide electricity to remote sites, or to houses that are also connected to the utility grid. But the prices! A small turbine can cost $US 2,000! A medium turbine $3,000! A large one can cost $8,500 – and that’s without the rest of the equipment you will need, and installation costs! Although wind systems require some attention, if you build a strong system, following a proven design, wind-electric systems make great economic and environmental sense.
How much FREE electricity will I get? There seems to be a myth that wind power produces little power. Strange, when a 1.8-megawatt turbine produces enough power for 1,000 homes.
More realistically for the DIY wind turbine maker, a small wind turbine, with a rotor diameter of 7 feet (2.1 m), and a swept area of 38.5 square feet (3.6 m2) will produce, per month, at average wind speeds of 10 mph – 80 KWH! This is enough power for a low-energy home, yacht, or business. A medium sized wind turbine with a rotor diameter of 10 feet (3 m) and a swept area of 79 square feet (7.3 m2) will produce, per month, at average wind speeds of 10 mph – 130 KWH! This would be suitable for a medium-energy home, business, or school. A large wind turbine with a rotor diameter of 12.5 feet (3.8 m), and a swept area of 120 square feet (11.2 m2), will produce, per month, at average wind speeds of 10 mph – 230 KWH! This is for big energy consumers. A huge wind turbine with a rotor diameter of 56 feet (17 m), and a swept area of 2,462 square feet (229 m2) will produce, per month, at average wind speeds of 10 mph – 5,060 KWH! These power large farms, very high-energy businesses, villages, islands, and massive heating projects.
Smaller turbines can be built for boats, caravans, cabins, or where only a small amount of electricity is needed. But for significant amounts of energy, you need a large enough rotor, as this is the wind turbine’s ‘energy collector’. When sizing a wind-electric system, you don’t add windmills in as you need them, as you can with solar panels. Because wind is more cost effective as you increase in system size, most people put up only one wind turbine, big enough to significantly slash their electric bills, or to fulfill all of their energy requirements for the foreseeable future.
System Components: The turbine is only one component of a wind-electric system, and very often is not even the most expensive component. You need all of the necessary components to have a functional system. Plan ahead to buy quality components properly matched to each other and to your energy use.
A complete wind-electric system includes: • Turbine—blades + hub = “rotor,” which is the “collector” of the system. • Tower—supports the turbine, getting it up out of the turbulent zone created by trees and buildings, and exposes the turbine to more wind • Wiring and conduit—carries the electricity down the tower and to power-conditioning equipment • Controller/Electronics—controls charging of battery or input to inverter • Batteries—used for storage in off-grid systems or grid-tied systems with battery backup • Inverter—converts direct current (DC) electricity from batteries or rectifier to alternating current (AC) for home use or “storage” on the utility grid • Metering—allows user to understand and manage system operation.
Small wind turbine: needs a controller or inverter, and is suitable for battery less grid-tie or 12, 24, 48 VDC battery charging
Medium sized: needs a controller or inverter, and is used for charging 12, 24, 48 VDC batteries Large: needs controller, dump load, and inverter. Suitable for battery less grid-tie or charging 48 VDC battery.
Huge: suitable for battery less grid-tie
How does a wind turbine actually produce electricity? The rotating blades convert the wind’s kinetic energy into rotation in a shaft. The rotating shaft turns an alternator, which makes electricity. The electricity is transmitted through wiring, down the tower, to batteries, or an inverter. The blades are designed to intercept wind and capture its energy. Most modern wind generators have three blades, to compromise between the highest efficiency possible (one blade) and balance (multiple blades). The blades must turn to face the wind, so a yaw bearing allows the wind turbine to track the winds as they shift direction. A tail directs the rotor into the wind. In small-scale designs, the rotor is connected directly to the shaft of a permanent magnet alternator, which creates Alternating Current. This wild, three-phase electricity means that the voltage and frequency vary continuously with the wind speed. The AC output is used to either charge batteries or feed a grid-synchronous inverter, which turns it to steady, usable Direct Current. In small designs, the rotor is connected to the alternator, eliminating the need for gears. In larger systems, a gearbox is used to increase alternator speed from a slower turning rotor. A governing system limits the rotor rpm and generator output to protect the turbine from high winds. A shutdown mechanism is also useful to stop the machine during an extreme storm, or when you want to service the system. Understanding the Ratings Wind turbine rating is difficult because rated output is pegged to a particular wind speed, and different manufacturers compare different wind speeds to better promote their particular model. To understand the real power of wind, cube its speed. For example, 10 kph of wind, gives 10 x 10 x 10 = 1,000 watts. Or, a 10% increase in speed gives a 33% increase in power. This means that very small increases in wind speed create huge increases in power. This also means that a turbine that produces 1,000 watts at a wind speed of 28 mph, might produce only 125 watts at a wind speed of 14 mph – so half the wind produces 1/8 of the power. So ignore the rated peak output of a turbine, and look for the monthly (or annual) energy production you require (from your energy audit), estimated for the average wind speed at your site. After all, long-term energy is what you’re after, not peak output! If, for example, you know your home has 10 mph winds, and you need 400 KWH per month, you know what turbine to build. Knowing a turbine’s swept area may also help you calculate the annual energy output for the wind turbine. Jim Green at the National Renewable Energy Lab (NREL) developed a formula: annual energy output (AEO) in KWH = 0.01328 x rotor diameter (ft.) squared x average wind speed (mph) cubed. Easy!
Getting Started: Consider: Is it your aim to slash your bills, or to be completely independent? Are you going to be stand-alone, or will you still be connected to (and adding into/taking from) the grid? If you’re staying connected to the grid, will your local power company pay you for the electricity you generate?
First you need an energy audit of your home. Go to www.njcleanenergy.com for an accurate home energy audit, and great ideas on saving electricity and money. Sit down with your family, work out how many kilowatt-hours you all use, and find out where the waste is. But be realistic, reasonable, and think laterally. Just because you are now horrified at how much electricity your plasma TV uses, doesn’t mean the kids are never allowed to watch it. You may consider a smaller, more efficient TV for weekly use, and save the plasma for the weekend family movie.
Next, work out your location’s average wind speed, at a website like www.awea.org for the USA. When you know how much energy you need, and how much your wind will provide, you will be able to see the size of turbine you will need.
Now that you have a good idea of what you’re after, check out the DIY Wind Power Kits at EarthEnergyPlus.Com These kits have been selected with the DIY novice in mind, and include all the information you will need to build your own electricity-producing wind powerDetailed lists of the tools, parts, and where to get them.

My Personal Opinion on Home-Made Wind Turbines
We seem to be in a real economic bind these days with this recession. If you are like me you are probably looking for ways save money wherever you can. One area that I started to investigate was generating electricity at home. I took a real close look at wind power for home use, and I was shocked at what turned up. Here is my personal opinion on home-made wind turbines.
I think home-made wind turbines can be dangerous. You see, when you make these things you really have to know what you are doing. The blades must be designed and fabricated properly or you have a real potential for hurting someone. If the blades are over stressed in a high wind condition, the blades can shear off and be sent hurling across the neighborhood. Can you say lawsuit? You should leave the wind turbine making to the professionals who know what they are doing.
I also believe that wind turbines for home use are not reliable. What I mean is this, these devices rely on a steady source of atmospheric wind to be used successfully. There are very few geographical regions where this type of wind is available. So what happens is the machine will not generate the type of electricity you are counting on and end up being a total waste of money.
Finally, I know that home-made wind turbines are unrealistic. By this I mean that the size of machine you really need for home use to make a difference is totally unfeasible. Do you know the blade radius required for one of these devices needed to power you home? For the typical home in the US the blades should be over twenty feet long! How would you ever put one of these on your roof or in the backyard?
There is a simple alternative to wind power for home use and that is magnetic power generation. These devices are simple, safe, and environmentally clean. You can make this device in an afternoon using parts found at a hardware store. You can make a system that supplements or replaces your energy needs, and it’s really up to you. There are easy to follow step by step guides available to show you how to do this.
You can make all the free energy you want with a home magnetic power generator.

Cost of Wind Turbines
In the 100 years or so since wind turbines were first used to produce electricity, they have seen many alterations, resulting in more effective and versatile units. Despite being superior in every measurable way, they’re also now more affordable than ever. Wind turbines generally fall into a few basic categories, each of which is intended to serve a specific purpose and will likely be more or less appropriate depending on the potential buyer’s needs.
Since they were introduced around 1930, large-scale commercial wind generators have improved in a number of ways. Enhanced blade design, more durable materials, and more efficient and reliable performance are some of the areas in which they’ve gotten better. In order to handle high winds consistently and thus generate a large amount of energy, these turbines are usually made from super-heavy duty materials.
As the strongest and most relentless winds are mostly in remote areas like shorelines, large-model wind turbines usually need to be located in these areas. Being “out of the way” like this means that it would be expensive to have to repair them all the time, so it’s a must that these units are especially reliable. Large-scale turbines often exceed 0,000 in price, which is due in large part to these factors.
Wind turbines for use in a residential environment are essentially scaled-down versions of those larger, commercial units. The most common problem encountered by the first generation of wind turbines for residential use was that they weren’t able to easily adjust to shifting wind patterns, which are especially common amid the buildings and other obstacles that are typical of residential settings.
Weight was also a problem for the first generation of residential-use wind turbines. It would usually be necessary to have a strong, purpose-built tower to support them. Ultimately, the drawbacks and costs were usually too much for many homeowners to really consider.
Micro turbines, the latest phase in the evolution of residential-use wind turbines, rectify the problems that plagued earlier versions. The main improvement with these turbines is their capacity to produce power from lower winds, which allows them to be used even without being mounted on towers. In some instances, it’s even possible to set up a micro turbine directly on your roof. These compact turbines are turning at all times, and this makes up for the fact that they don’t have the maximum power generating capacity of some of the larger models. With a price range of about 0 to ,000, these micro turbines are also relatively inexpensive and are well within the area in which the electrical bill savings they provide will almost immediately justify the investment
Wind turbines vary significantly in terms of their size and power, and the price tends to vary accordingly as well. By building a wind turbine yourself, you can bring the cost down even more. All you need are some common tools and the right instructions, and just about anyone can build a wind turbine, and get the lifelong savings that come with it.

Eric Moore became interested in renewable energy after building an electric powered bike. Shortly after he began riding the bike to work, he thought, why not recharge the bike’s batteries with solar power and commute to work completely free and totally pollution free. He then created a website to share his experience and knowledge with others. For many more articles about home solar power visit: Home Solar and Wind Info.
