Zephyr combines advanced wind turbine technology with Japan’s world-renowned manufacturing craftsmanship, to successfully develop the Airdolphin Z-1000-48 PRO 1000 watt wind turbine — a next-generation, low-mass wind turbine which instantly adapts to changing wind conditions, from slight to stormy.

The total weight of the Airdolphin PRO is 17.5 kg (38.5 lbs). Unlike larger turbines, the Airdolphin’s low mass allows it to be mounted on existing structures like remote telecommunication towers, transmission line pylons and billboards, as well as near roads, railways and airports. Even factory and urban rooftops can become cost effective locations for producing usable electrical power.

The Airdolphin PRO is also ideal for:

? Mountainous areas

? Ocean areas and islands

? Repeater stations

? Remote monitoring sites (web cameras, GPS receivers, wireless applications)

? Street lights (no utility electricity required)

? Public facilities (dams, weather observatories, etc.)

? Communication base stations

The blades of each Airdolphin are created with Zephyr’s patented SD blade technology (noise reduction ridges). Their designers were inspired by the feather patterns of owl wings, which allow owls to fly in silence. This technology applies a series of thin ridges to the surface of each blade, creating micro vortices to keep the airflow attached to the airfoil longer than conventional blades, thus reducing decibel count.

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 generator?

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 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.

The sun’s energy or the solar energy is the most abundant form of energy available on earth. The sun is capable of giving us more than heat and light. The sun has been one of the biggest factors dictating every living being’s stay on the earth. If we go the right path, we can harness more from the solar energy, like generating power for daily use.

What are the advantages of solar power?

The solar energy solution is gaining popularity amongst the alternate energy solutions.

• Green energy solution: When you look at the solar energy solution, you will realize that it uses absolutely no fuel other than the sun’s light. Moreover, it does not release into the atmosphere anything harmful.

• Cheapest power solution: First, the energy comes free. Then, the installation cost is a one-time cost. Finally, the investment is recovered within a few years of installation, making the power generated by solar energy absolutely free.

• Convenience of storage: You cannot store conventional power but you can store solar power for future use. The sun’s energy comes to rescue even in the times of darkness! Storing it also ensures a 24×7 supply of power, thus saving you from any power outage.

• Low on maintenance: The solar energy systems are easy to maintain. They do not involve high costs or too much effort, thus letting you reap the benefits of the solution comfortably.

How can solar power be used?
Solar power can be used in our everyday lives by adopting the following solar power systems:

• Solar cooking system: Solar cooking is about cooking without lighting a fire or using electricity! Before you wonder, let me tell you that solar cooking is not about bland food. You can cook in more ways than one – boil, roast, or bake, cook the way you want! The only demand that solar cooking makes of you is being patient; it is a matter of more than a few minutes. However, it is not asking for too much given that you will get tasteful and healthy food without worrying about paying your gas or electricity bill.

• Solar lighting system: You can now light up the entire house, use every electrical appliance without thinking about cutting down bills. The solar lighting system lights up your house even in the nights, thanks to the power storage feature it has.

As the term suggests, bio-fuels are fuels that are formed when biological matter decomposes. The bio-fuels are mostly derived from plants. Bio-fuels exist in all the three states of matter: solid, liquid, and gas.

Difference between bio-fuels and fossil fuels
Bio-fuels are different from fossil fuels in the following ways:

• Fossil fuels take a million years to build whereas bio-fuels can be made extremely fast, in a matter of days.
• Fossil fuels generate huge amounts of pollution. Bio-fuels are comparatively safer.
• Bio-fuels are renewable sources of energy unlike fossil fuels.

Different types of bio-fuels
Bio-fuels have been categorized into four types: first generation, second generation, third generation, and fourth generation.

The first generation bio-fuels are derived from vegetable fats, starch, and sugar, which are in turn derived from food-crops. The first generation fuels are also derived from animal fats. Biogas, bio-diesel, and vegetable oil are some examples of this type of bio-fuels.

The second generation of bio-fuels is mainly derived from waste biomass, thus making it a more balanced option compared to the first-generation bio-fuels. Different kinds of alcohols and diesel generated from wood fall into the category of second generation bio-fuels.

The third generation comprises of bio-fuels derived from algae. Algae are farmed on large scales for creating these bio-fuels. The algae fuels are extremely environment-friendly as they can easily decompose into the soil without harming it.

The bio-fuels in the fourth generation are derived by a method in which micro-organisms are raised to work with carbon dioxide to generate fuel.

Advantages of bio-fuels
Bio-fuels prove advantageous in the following ways:

• Bio-fuels lessen the burden on gradually-vanishing fossil fuels.
• Bio-fuels are environment-friendly. They help reduce carbon emissions into the atmosphere.
• Bio-fuels, especially, bio-diesel prove to be very cost-effective for consumers.

Disadvantages of bio-fuels

Bio-fuels are not bereft of criticism. Though beneficial for the environment, bio-fuels have its disadvantages, paradoxically in the environmental purview. Bio-fuels have received criticism for many reasons, a couple of which are stated below:

• Economists have long debated on the usefulness of first generation bio-fuels when compared to the lack of food they cause. Generating fuel from food crops makes food crops unworthy of human consumption. Some people believe that being a higher priority than fuel, food should not be farmed for making fuels but for human consumption.
• Making bio-fuels require acres of farming land, thus encroaching upon the natural habitat of plants and animals.
