Microprocessor-Based Technology

The AIR is by far the world’s number one selling small wind turbine.In late 2001 we introduced an entirely new level of technology previously found only in state-of-the-art mega-watt-class wind turbines.

The Air X incorporates a new microprocessor-based technology that results in increased performance, improved battery charging capability, greater reliability and the reduction of “flutter” noise from the machine.

The controller allows for peak-power tracking of the wind by optimizing the alternator’s output on all points of the cubic curve and efficiently delivers the energy to the battery. The turbine’s smart controller allows it to actually control blade rotation speed thus eliminating the buzzing noise commonly found with most small wind turbines.

Quieter operation

Previous AIR wind modules relied on their aero-elastic blade design for protection in high winds. This caused a loud flutter noise in winds above 35 mph (16 m/s). The Air X circuit monitors the wind speed and electronically slows the blades as it reaches its rated output preventing it from going into flutter. This results in a much quieter wind turbine. In high winds, the Air X will continue to produce power at a reduced level until the wind decreases, at which point maximum potential output will resume.

Improved Battery Charging

Previous AIR designs required 300-400 amp hour battery banks so the trickle charge of the wind turbine could be adequately absorbed. The Air X charge controller periodically stops charging, reads the battery voltage, compares it to the voltage setting and if the battery is charged, it completely shuts off all current going to the battery. This function is performed within a few milliseconds. The closer the battery is to reaching its full state of charge, the more often the Air X circuit repeats this action. This means any size battery bank from 25 to 25,000 amp hours or higher can be charged safely. When the battery has reached its charged state, the Air X will slow to an almost complete stop. Only when the battery has dropped below its voltage set point will it startup and resume charging.

What is a wind turbine?

A wind turbine is also referred to as a windmill or wind generator. Though the terms are used interchangeably, there is a minor difference.

The wind turbine is the device that makes use of the wind energy to produce mechanical energy. This mechanical energy is then used as is or converted into electrical energy. A windmill uses the mechanical energy as is for pumping out water or for grinding purposes whereas the wind generator is the one that produces electrical energy.

What are the different types of wind turbines?

Wind turbines are classified into two kinds based on their orientation:

• Horizontal axis turbines – The blades in these wind turbines rotate along a horizontal axis.

• Vertical axis turbines – The blades in these turbines rotate along a vertical axis.

The horizontal axis wind turbines are more commonly used. They are more efficient that vertical axis turbines.

What are the advantages of installing a wind turbine?

Let’s look at the major advantages of a wind turbine:

• Power-saving: Since the wind turbines use a free energy, the wind energy, they prove to be a very cost-effective mechanism for generating electricity, thus helping not only save power but also generate power for the world.

• Cost-effective: The only cost involved in installing a wind turbine is the initial cost and the cost of maintenance. The energy comes free and there is no other fuel.

• Environment-friendly: The wind turbines are environment friendly in a way that they do emit harmful gases or affect the environment in any way.

• Uninterrupted power supply: A wind generator helps you become independent of government’s electricity supply. Moreover, you overcome the hurdles of power outages.

What are the factors you should consider for installing a wind turbine?

While installing a wind turbine is extremely beneficial for you and for the rest of the world, you must take care not to implement the solution in an incorrect way. You should take into consideration the following when installing a wind turbine.

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.

With the world slowly moving to the much-dreaded energy crisis, it is important that we reduce our dependency on non-renewable sources of energy. Non-renewable sources being renewable are about to get extinct. Renewable energy solutions refer to those energy solutions that can keep churning energy without exhausting the resources. Three types of energy solutions fall into the category of renewable energy solutions: solar energy solutions, hydro energy solutions, and wind energy solutions.

Solar energy solutions: The sun’s energy is the most abundant energy available on earth. Make use of this free energy. You can employ solar power solutions at home. This will not only cut down power bills but also help you contribute to a greener world. Solar power solutions comprise of solar cookers, solar heating systems, solar lighting systems, solar dryers etc.

The sun has always been a source of heat energy and light energy. With the advancement of technology, the sun’s energy can be used to create other forms of energy.

The solar energy systems have many advantages apart from being cost-effective and environment-friendly. They are low on maintenance thus saving your time and effort. Also, solar systems give you a return on investment very soon, thus making the systems free after some time. Cooking with solar energy is also considered extremely healthy. Families have started employing solar energy as a power solution at their homes.

Hydro energy solutions: The hydro energy or water energy is an effective renewable energy. One can convert the hydro energy into electrical energy to run vehicles and various electrical appliances. Hydro energy is typically generated on a large scale. It has been estimated that 90 percent of the electrical energy produced by renewable resources is produced solely by hydro power. Dams are built to help generate electricity by tapping the water power.

There have been some concerns about using this energy because it is supposed to adversely affect the water-borne flora and fauna.

Wind energy solutions: Windmills were in existence even in the years before the birth of Christ. They helped tow boats and pump water. Eventually, post-industrialization, they became a source for generating electricity.

Windmills and wind turbines have never been passé. Wind energy can help generate tons of megawatts of electricity. When employed at individual estates, it can help do away with conventional power sources. An excellent renewable source of energy, the wind energy will go a long way in promising a good future to generations to come.
