Vaneless ion wind generator

February 26th, 2010 Grace No comments

A vaneless ion wind generator is a device that produces electricity directly by using the wind to pump an electrical charge from one electrode to another. It is a type of wind power, although wind energy is usually extracted to make electricity by means of a wind turbine.

Electrostatic wind generators work by spraying water from a nozzle facing a toroidal charged electrode. This induces an opposite charge in the water and when the water flows out of the nozzle, each drop carries a small amount of charge. These water droplets are then blown by the wind, going through the center of the charged toroid without touching it. The droplets then hit a fine mesh, adding to its charge. The other alternative is to use the Earth as the second electrode. The main advantage of this system is that it has no moving parts except the water droplets. The disadvantages are that it needs a constant supply of water, its wind profile can’t be reduced, it requires many small parts, and it has to be well-crafted to reduce corona discharge losses.

Protecting Wind Turbines From Generator Failures

The ring is designed for OEM installation or easy up-tower retrofit.

The ring is designed for OEM installation or easy up-tower retrofit.

Electro Static’s shaft grounding ring prevents damage by channeling harmful shaft currents away from bearings.

Mechanic Falls, ME – By safely channeling harmful shaft currents away from bearings to ground, Electro Static Technology’s new AEGIS WTG wind turbine grounding ring prevents bearing damage that could otherwise cause generator failure, unplanned downtime, costly repairs, and lost revenues.

Maintenance-free, effective at any RPM, and available for any size wind turbine generator, the ring is designed for OEM installation or easy up-tower retrofit.

High-frequency currents induced on the shafts of wind turbine generators can reach levels of 60 amps and 1200 volts or greater.
If not diverted, these currents will discharge through the generator’s bearings, causing severe electrical damage that results in bearing failure and catastrophic turbine failure, sometimes in as little as six months or less.

The AEGIS WTG’s patented conductive microfiber technology effectively steers these currents away from the bearings and safely to ground.

The WTG is engineered to safely divert up to 120 amps of continuous shaft current at frequencies as high as 13.5 MHz and discharge up to 3000 volts (peak). Ideal for use as part of a preventive maintenance program to protect against premature bearing failures, it can be installed whenever bearings are replaced.

Homemade Wind Generator

What is a homemade wind generator?

Generally you could say that a wind generator is a machine that uses wind energy to produce electrical energy. It captures wind energy and converts it into mechanical energy that moves the blades of a motor to produce electrical energy. Wind generators help produce thousands of megawatts of electricity. They are also a very popular power solution for individual farms. They are ideal for large areas with good wind speed.

Setting up a home wind generator does not need professional help; individuals can easily set it up with the help of numerous guides available in the market. The components of a wind generator are also easily available in the market.

How does a wind generator differ from a windmill or wind turbine?

Wind generators have been in use for a long time in the form of windmills or wind turbines. Years ago, when electricity was not invented, wind turbines were used to pull boats and pump out water.

Even now, the terms, wind generator, windmill, and wind turbine are used to refer to the same device.

What are the advantages of using a wind generator?

The advantages of a wind generator are many. Let’s look at a few of them.

Environment-friendly: Wind generators prove to be environment-friendly in two ways:

  • They do not emit harmful gases in the atmosphere nor do they leave any harmful residual component.
  • They do not use any fuel to produce electricity, thereby helping the cause of the environment.

Power-saver: Wind generators are an alternative power solution. They do not use any non-renewable sources of energy, thus helping in times of energy crisis.

Economical: Though the initial cost of setting up a wind generator seems high, the cost of generating electricity in the long run becomes nil. So, you will be getting electricity absolutely free after a few years.

Independent option: Wind generators do away with the dependence on power plants and the government for electricity. With a wind generator in your land, you have your own power plant for life.

24/7 power: With wind generators, you can say bye to power outages forever. You will get continuous, uninterrupted power supply for your entire house and land.

Power storage: A homemade wind generator also allows you to store power for use later. This feature makes it an amazingly lucrative power solution.

If you want to help the world and fight the current energy crisis, invest in a wind generator.

A new type of wind generator

November 24th, 2009 admin No comments

a-new-type-of-wind-generator

Electrical power generated at the floating Air Rotor is transferred down the tether to ground level equipment. Depending on size of the Air Rotor, power is sent to users ranging from campers to large power grids. Helium (an inert non-flammable lighter-than-air gas) sustains the Air Rotor which ascends to an altitude for best winds. No towers or heavy foundations are necessary and sizes range from small “backpack” models to large megawatt generating devices.

a-new-type-of-wind-generator-1

All competing wind generators use bladed two-dimensional disk-like structures and rigid towers. The Magenn Power Air Rotor system is a closed three-dimensional structure (cylinder). It offers high torque, low starting speeds, and superior overall efficiency thanks to its ability to deploy higher. The closed structure allows Magenn Power to produce wind rotors from very small to very large sizes at a fraction of the cost of current wind generators.

a-new-type-of-wind-generator-2

This electrical energy is transferred down the tether to a transformer at a ground station and then transferred to the electricity power grid. Helium (an inert non-reactive lighter than air gas) sustains the Air Rotor which ascends to an altitude for best winds and its rotation also causes the Magnus effect. This provides additional lift, keeps the device stabilized, keeps it positioned within a very controlled and restricted location, and causes it to pull up overhead rather than drift downwind on its tether.

Massive Generator To Wind Through Greenville

November 19th, 2009 admin No comments

massive-generator-to-wind-through-greenvilleThe 880,000-pound generator is on its way to Duke Energy’s Cliffside Steam Station in Boiling Springs, N.C.

 

Deputies said that the 1.5 million pound transporter that is carrying the power plant part travels at about 5 mph because of its size. They said that authorities will be escorting the transporter as it snakes its way through the county.

 

Officials said that the generator will enter the county at about noon on Friday near Princeton along Highway 25. It will travel up the highway and park near the intersection with Interstate 85 on Friday night. From there the transporter will wind its way through the west side of Greenville before parking just south of Highway 11 on Sunday night. The motorcade will continue to near the North Carolina state line on Tuesday morning.

 

Deputies said that motorists should try to avoid the rote that the massive piece of equipment will take as it will cause traffic delays where it travels.

Wind generators have been in use for a long time in the form of windmills or wind turbines. Years ago, when electricity was not invented, wind turbines were used to pull boats and pump out water.Surprisingly the first use of the wind machines was for grinding grains as early as 200 B.C in Persia. It was also introduced in the prosperous and powerful Roman Empire in 250 A.D. The year 1900 saw the maximum number of windmills being used in Denmark. Almost 2500 windmills were installed to provide the much needed mechanical load to pumps and gave a peak power of 30MW.

 

Even now, the terms, wind generator, windmill, and wind turbine are used to refer to the same device.

 

What are the advantages of using a wind generator? The advantages of a wind generator are many. Let’s look at a few of them.

With more and more fuels getting wasted and used, there are very few options remaining. Bio-fuel is one of the options and to add to it is the use of solar panels for driving motors and making electricity. The third option is harnessing the wind power. So build a wind generator today and do something good for your home and for our environment.
