www.maglevwindturbine.com Demo CGI for proposed 2GW Magnetic Leviatated wind Turbine. *Efficient Frictionless Power Generation with less maintenance, compared to HAWT. No oil change or replacement of the bearings, gears. Since, MAGLEV does NOT require such. ** Current bearing technology has forced wind turbine designers into horizontal spindle three bladed wind turbines. In this design the huge blades are connected to a spindle in the center. The bearings that support the spindle and control the pitch of the blades (which can be hundreds of feet long) see huge pitch-moment loading, some of which is manifest as torque energy that is focused through the center spindle. The target speed for the spindle is 18 or 20 rpm and the bearings holding the spindle are mounted in a huge casting which also contains a large gearbox stepping the speed up to 1800 to 2000 rpms which allows for the proper surface speed relationship between the coils and magnets. It is necessary to invert or condition the current, which is expensive. This gearbox is full of many large bearings, gears and castings; for a 2 MW turbine the gearbox can easily weigh 30 tons. This gearbox needs to be mounted on the top of a pole more than 150 feet in the air and be able to support the turbine blades under full-force wind conditions. ***MAGLEV Power Generation, the pitch moment ratio is closer to 1-to-1 then the 100-to-1 as with a horizontal spindle design.

Product Description Designed and made to pick up the wind power as much as possible. The efficiency is graded as 0.48 in converting wind power to the mechanical power, which is at the very top end (the highest is 0.5). The exact same blades are widely used in commercial wind generators. The performance of the blades is much better than home brewed ones.
Wind turbines are the answer to today’s high cost of energy. Totally independent from the price of oil,gas or coal,electricity created from wind power is the best answer to one of today’s most pressing problems–the high cost of fossil fuels. There are other solutions which can help of course. Solar power is a good example but,at the present time, solar panels are still very expensive and have limited power output. Their best use is as an adjunct to wind power. They can be used in the form of roof panels on a building to supply additional power.
Nuclear power is another obvious answer and this form of power is being developed in various places around the world. The initial cost of nuclear power plants is very high however and there is much opposition to their use after the Three Mile Island and Chernobyl accidents. Properly built and supervised nuclear power stations will probably be a large part of future power supply around the world.
Wind power is presently the most promising power source for small scale power generation. Individually owned wind power generators can supply a substantial portion of our power requirements in the years immediately ahead. Wind turbine generators are now manufactured by a number of companies and are in use by rural and city dwellers on an increasing basis. Another alternative is to build your own wind turbine at a very substantial saving. It is possible for any farmer or home owner, whether located in city or country,to access this free form of electric power and so become completely independent of the power utility.It is not necessary to have continuous high winds. Power is generated by even the gentlest of breezes.
A very good wind turbine can be constructed using used or new auto parts. Installation can be on a building’s roof or on it’s own freestanding tower. It is actually quite simple to construct a wind turbine from available plans and instructions.The average person with a little home workshop experience can build one or several of these turbines quite easily. The power utility in many areas will now buy any excess power which you generate. This type of wind turbine has been proven to be extremely relisble and was used widely on farms in the period from 1930-1950s. Two or three of them can be built to supply as much power as needed and the power can be stored in batteries ready for use. Build a wind turbine and the wind will find it and bring you free power.

Energy costs keep sky rocketing with no end in sight. Pollution levels are increasing and our planet is facing a warming trend that could have devastating results. So the question is what can the average citizen do to save money and help the environment at the same time? One great way to help is to lower the amount of electricity your home purchases from the utility company by creating your own power. There are a few ways to do this, and wind power is one of the easiest and more reliable ways to produce energy at your home.
What is a Wind Turbine?
A wind turbine is a simple machine that collects kinetic energy produced by wind currents and converts this energy into power that can be used in the home. Wind turbines are installed on high towers; these towers are usually around eighty to one hundred and twenty feet high. Towers must be high enough to allow the turbine to be above any turbulence generated by objects on the ground. The higher the altitude also results in higher wind speed and in turn, a higher amount of energy can be produced.
How do Wind Turbines Work?
Wind energy is used to create mechanical energy. Turbines have blades that are turned by the wind; these blades turn a shaft to which they are connected. The shaft is then connected to a generator; the mechanical energy is transferred into the generator through the shaft and converts the mechanical energy into electricity. This electricity can then be used in the home for any electrical need. Homes that are using wind turbines to produce power are still hooked up to the power grid. Being hooked up to the power grid allows the home to still have power when wind currents aren’t strong enough to produce electricity. Another benefit of continuing to be connected to the power grid is that at the times your wind turbine is producing more power than your home can use, the utility company is absorbing the extra energy and paying you for it. This can lead to very low electric bills. A wind turbine can lower your power bill by 50-80% depending on the amount of wind in your area.
Types of Wind Turbines
There are two main types of turbines: horizontal- axis turbines and vertical-axis turbines. Turbines also come in different sizes as well. Utility companies use wind turbines that can range in size from 100 kilowatts up to several megawatts. These larger turbines are found in groups on wind farms. If you ever drive over the Temecula pass in California, you can see large wind farms along the highway. It is a spectacular site. Small turbines, 100 kilowatts or less, are used at homes. These are place on towers on the homeowner’s property and then used to provide some of the energy needed to run the home. Since the size of the tower is quite large, they are usually used in areas where the home is on one acre or more. There are very small turbines on very small towers that may be able to be of use in urban areas or on smaller lots.
The Future of the Wind Turbine
In September of 2008, the U.S. Senate passed a bill that grants a one-year extension of the renewable energy production tax credit. If passed by the U.S. House of Representatives the tax credit would be available until December 2009. Wind power is a viable part of the solution to lessen our dependency on fossil fuels. Wind power is a renewable resource and produces no harmful pollutants. The future looks bright for wind power and hopefully, as a result, there will be a bright future for our planet too.
