Vertical Wind Generators – Sometimes a Better Choice than Horizontal

With the rising price of fuel oil, and the rising costs of energy in general, there is increasing demand for home generated power, be it from solar-electric, solar thermal heating, or wind generated power. Of those three options, wind generated power is by far and away the most mature option, with the best odds for getting a reasonable payback in a typical home owning time frame.

With wind power generators, there are two general types to consider: Horizontal blade generators, and vertical wind generators. Horizontal generators are the type most people associate with a windmill or wind generator – they have blades that rotate perpendicular to the ground, with the axis of rotation being horizontal. They have significant advantages in efficiency, but work best when put on a tower, where they can catch the upper contrail winds, and they’re more mechanically complex. On top of this, they’re also a hazard to birds, and can be quite noisy.

For rural applications, horizontal generators reign supreme. When attached to someone’s home for net metered power generation, they run afoul of local zoning ordinances and home owners associations, because, bluntly, there’s no real way to make a 35 tall wind turbine look like it’s part of a Victorian deco home plot. Couple this with dead birds, loud noises, and people afraid they’ll blow over in a storm, and there’s a lot of barriers to installation.

The best choice for a homeowner is a vertical wind generator, which rotates on a vertical axis. There are drawbacks – they’re about half as efficient as the more traditional wind turbine, and they may need a small “boost” from an electric motor to get their initial rotation going; their minimum threshold for usable wind is a bit lower.

On the other hand, vertical wind generators have the advantage of being suitable for a ground level installation. They can be put out in the middle of the back yard, or on top of the roof of your garage. They’re much quieter in general than horizontal generators, and because they operate at a lower altitude, they’re less likely to kill birds. They also don’t need a yaw element (the “tail” of a conventional turbine blade) to steer them into the wind direction, as they can generate energy from any wind direction the breeze is blowing in from.

Another benefit of vertical wind generators is the range of vendors supplying them; horizontal generators are good for industrial applications, but they’re often $12,000 or more to install. Vertical wind generators are often under $5,000. With most electrical prices set the way they are, a vertical wind generator can pay for itself in home use in around 20 to 25 years. (A horizontal generator will be more efficient, and generate power at a lower baseline wind speed, making its higher up front cost make more sense).

Vertical wind generators are also (generally) more aesthetic. They’re less likely to be noticed as being an odd addition than a 36′ tall tower would be. Some of the more aerodynamic ones tend to look like short rotating sculptures, and there are even bladeless or rotorless turbines.

The most common type of home deployed vertical wind generator is the Savonius type, which uses airfoils and wide variable pitch blades to generate power. Built more or less like large anemometers, they run into problems with generated drag; more efficient ones use variable formations on the blade to minimize drag when they’re being swing through the incoming breeze.

The other type of wind generator is the so-called ‘egg beater’ windmill – they can scale up to the full industrial size installation, though they’re also suitable for small home installations. They’re much more efficient, but also noisier, and a bit more effort is required to maintain them.

Depending on where you’re setting your vertical wind generator up, your local utility company may offer credits for doing so, and nearly 90% of the utility companies in the US offer some form of net metering, where excess electricity you produce from your vertical wind generator is sold back to them and credited against your bill. Look seriously into the options your utility company provides before investing in a vertical wind generator, and consider it an investment in cheaper power down the road.

Today the hook phrase is going green. Everybody is fascinated in ways they can be kinder to the planet and still get their energy needs met. Wind power is a renewable energy source and a basic wind turbine will provide power for many years.

Wind power using a wind turbine is a good supplement or alternative to solar power. Dark, overcast days are frequently windy. If you build the wind turbine on your own, you can even save money.

Building a wind turbine can be a fun project for the whole family. To go one step further in your conservation efforts you might consider using recycled materials wherever possible. The materials needed to build a wind turbine are all available at your local hardware store and can be purchased for less than two hundred dollars.

Blades can be made of wood, cardboard or PVC piping. The blades need to be the correct weight for the size of turbine you’re making. The base can be made of a wooden or metal pole.

Before you begin, find a good manual that will explain how to build a solid structure. The manual should give you detailed building instructions in a format that is easy to follow. Step by step instructions are the easiest to follow. The manual should include a list of all the materials you’ll need to build your wind turbine. Some manuals will offer you alternatives that you can use for building materials. The book should give suggestions on where you may find the needed materials, but you should be able to find most at your local hardware or home improvement store.

With a little basic knowledge and a bit of experience with simple power tools, you can build your own wind turbine. It is a good way to make the most of a bit of open space near your house. You can construct your turbine anywhere the wind blows. It is a great, inexpensive way to take part in your own green revolution.

If you have an acre of land or two, you can even build more than one and send energy back to the grid. Your power company will pay for the energy you send to them.

This is an easy way to save money on your energy costs. It is easy to do with a little knowledge and a set of instructions. You’ll feel great knowing you’re cutting down on your dependence on the grid, and you’ll save some money while you help create a greener household.

As fall is upon us, the chill down our spines can be far more than only the cool winds. Most probably it is the chill of your fear that you will not be able to pay your energy bills for heating these winter months! Well, the good news is, wind power will cut energy bills.

A stimulus plan from the government is helping home owners to make their homes more energy efficient. To qualify for the $1500 tax credit you must replace your doors and windows with the modern energy efficient models available. In addition to this, there are even some state governments that are giving businesses and residents incentives to make their own energy with wind turbines. And as wind turbines will cut energy bills, this looks like a very good alternative to me.

Now, of course, for this you will have to install a wind turbine on your property. Well, fortunately you can get very good wind turbines kits these days. Assembling one is easy. On the other hand, you can also build your own from scratch with the help of a good guide. This wind turbine tied in with some other measures will save you money. There is no doubt; wind power will cut energy bills.

Some of the measure you can take to make your home more energy efficient:

Leaky, poorly sealed and old windows and doors are normally responsible for most of the heat lost of a home. The technology for making energy efficient windows and doors has made a lot of advances and if yours are even only ten years old, replacing them will make a big difference.

OK, now you can say to me that tax credit or no tax credit, you still cannot afford to replace them. Fortunately, I also have good news for you here; there are cheaper options you can use to prevent the hot air leaking from your windows.

It is now also possible to buy window kits to fix your leaky windows with. Essentially these kits consist of a plastic sheet to put over your existing window and add another layer to prevent heat leakage. These kits are easy to use and inexpensive to buy.

So, I know these windows will still not be as good as the new ones, but at least it will be an improvement. It will still help you to lower your energy bill.

If it is possible for you, take advantage of the tax credit and buy new windows. If it is not possible, start with the other smaller ways you can use to save energy. It is best to get started now, and save now!

To conclude, do all the little things you can to save energy and if it is at all possible get a wind turbine as wind power will cut energy bills.

Building a wind generator is a great project for your family. Spend weekend learning about the benefits of wind power verses electricity produced at a plant and teach this to your children. Understand and verbalize the responsibility we have to our community and the environment around us. Devote the weekend to working together to build your wind powered generator. Give everyone a specific duty and allow them to take pride in their craftsmanship. This is a great way to spend some quality time as a family, learning new things and working together. The adults will save money while teaching their children valuable lessons.

Many people are turning to Wind Generators to provide power to their homes. These generators cost little to build and can be constructed in one weekend, in some cases. With a simple to understand set of plans and some positive thinking, you two can build a wind powered generated for your home that will produce free wind energy for your home for years.

For the first time builder, it is important to become familiar with the different parts of the wind powered generator and what all it entails. Familiarize yourself with the distinct parts of the generator. These parts consist of the blades, hub, body, towel and the tower for the wind generator.

Building the blades and hub are by far the most time consuming part of the entire project. Once these two parts are built, you are well on your well. The blades and hub are not difficult to build; they just take time and patience. Grab a buddy or make this a father-son project. The material you will need to build the blades and hub are easily accessible. You might even be able to obtain the blade material for free. Ask around, you may be surprised. While you are building these parts, order the motor for the wind generators.

If you order it in the beginning you will not have to wait around for it after the blades and hub are completed. The motor is the heart of the generator and is what converts the wind to energy. If you are environmentally conscious, as many of us should be, consider building the body and tail of your generator from recycled material. Recycled stainless steel, double wall chimney pipe is a great material to use as the body for the wind generator. This material can be obtained from your local chimney installer or from a dealer that sells wood stoves. Furnace dealers may have this recycled material, as well. Stainless steel is a great metal that protects the motor and internal moving parts.

Let your artistic flair shine through when designing your wind generator tail. Think of a funky theme or paint the tail a fun, bright color. You can paint is to match the color of your house or stencil your last name on it. The sky is the limit. Make it fun and pleasing to look at. Ask your children for ideas and let them participate. They will take pride in the work they accomplished and the good your wind generator is doing for the environment.

Design Features

Advanced over-speed control mechanism vs. old style furling

Problems with old style furling: Old style furling works well in an ideal, wind tunnel test environment. Realistically, wind speed and wind direction changes frequently and mechanical furling doesn’t have instantaneous response to actual changes of wind status. Especially in bad weather conditions, small wind turbine furling components wear out quickly, therefore, increases maintenance costs and shorten wind turbine service life or causes system failure.
Most of old style furling based wind turbines have three moving parts. It is the moving parts for mechanical over-speed protection that wear out and require a lot of maintenance. Operation of furling based wind turbines would lead to mechanical abrasion, cause vibration, malfunction, and failure of the wind turbine and other devastating results in the long run.
The rule of thumb for a reliable wind turbine is that the fewer the moving parts, the more reliable the wind turbine is.

The Windmax Solution: Windmax H series adopted Innovative over-speed control so it improves the reliability by abandoning the moving parts for mechanical over-speed protection and minimizing the moving parts to only two.

Innovative over-speed control design of the Windmax H series: The Windmax H series speed limitation abandoned the traditional failure-prone mechanical furling system and solved safety and reliability problems facing most small wind turbines. Advanced speed limitation of Windmax H series is achieved through advanced electromagnetic speed limitation supplemented by aerodynamic speed limitation by blade deformation. Electromagnetic braking is used in combination with Aerodynamic braking to reduce the rotational speed of the generator.
Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending Windmax H series turbine’s operating speed range into higher speed winds and lower speed winds which are missed by the old style wind turbines.

1. Electromagnetic speed limitation:
Controller will monitor the wind generator rotation through the wind generator output voltage and frequency, and will timely control wind generator rotation by generating reverse reluctance torque if necessary, according to different wind conditions and battery status. Electromagnetic control features quick response, high reliability and therefore ensures the entire control system to be highly reliable.

2. Blade aerodynamic braking:
In high wind speed conditions, patent pending blades will generate a reverse reluctance torque, so that the blade efficiency falls and the blade rotation speed starts to decline. With the continuing reluctance torque, blade rotation speed is limited to a certain range to prevent damage to the wind turbine blades.

Wind-solar hybrid power generation wind turbine system
Problem with single source renewable energy system:
1st Generation single source renewable energy systems such as solar systems or wind turbines don’t use renewable energy efficiently. Wind turbines creates less output during the summer, whereas during the winter the solar panels will produce less output.

Windmax Solution:
Our Windmax hybrid solar-wind turbine integrated wind and solar power sources capture the most energy in all conditions. Since solar and wind energy availability differs by locations, seasons and climates, solar and wind energy can be mutually complementary in that solar and wind hybrid systems make full use of wind and solar energy together to generate as much power as possible compared to a single energy source for power generation. A solar & wind hybrid system is more cost-efficient than wind or solar alone.

Easy-to-install, light weight, compact, reliable and maintenance-free wind turbines, designed for both land-based and marine applications.


Problem with old style wind turbine systems:
Most old style wind turbines are heavy weight with unpredictable reliability, hard to install and require lots of maintenance. Due to the fact that most installations are in very remote and inaccessible locations, the old style systems make regular maintenance costly and sometimes impractical.

Windmax Solution:
Windmax H series maintenance free design has a minimum of moving parts with inherent reliability. Our light weight, compact die-casting aluminum alloy generator design makes installation very easy. Rotor blades built with latest advanced thermoplastic engineering and precision injection molding technology is durable and efficient.

Higher performance at low wind speed
The problem with small wind turbine system on the market today: The most challenging problem facing small wind turbine systems is that power output is very low or close to nothing under low wind condition. The wind speed in most locations don’t stay at rated wind speed all the time, wind turbine actually operates at wind speed lower than rated wind speed at most of the time. In order to have good overall energy output, it is critical for small wind turbine to output as much as power at low wind speed.
The WindMax Solution: Strong Neodymium magnet PMA, unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. WindMax system components such as wind generator and blades are designed to output more electricity at low wind speed than other small wind turbines on the market today. WindMax system’s excellent power output under low wind speed results in greater energy production yield and lowest ownership cost.

WindMax H series components are built with advanced technologies

Generator: The generator is built using high-performance rare earth neodymium permanent magnets, so the alternator is compact and light weight with a high power generating efficiency. The unique winding and multi pole design reduces the start-up torque of the alternator that assures the WINDMAX-H series can generate electricity at low wind speed. The generator features class B insulation, IP55 class protection, and is designed with a sufficient cushion of overload to ensure overall wind turbine reliability.

Generator housing is made with precision cast technology from high strength aluminum to assure a high quality finish. It is designed for various working conditions such as severe climate, sand and salt corrosive environments and marine usage. Aluminum die cast alloys can withstand the highest operating temperatures of all die cast alloys. Ideal for demanding environments, it offers high strength and rigidity along with good corrosion resistance and heat dissipation.

Patent pending Rotor Blade design vs. traditional hand made fiber glass blades: Our Blades are made with the latest thermoplastic engineering and injection mold technologies. The blades are made of mixed reinforced fiber glass and nylon materials. These manufacturing technologies ensure the highest strength, flexibility of blades and consistency of the blade shapes. The blades will automatically slow the turbine in strong winds and reduce noise.
