Product Description

The Sunforce 44444 12-Volt 400-Watt Wind Generator harnesses the power of the wind to provide you with clean, free renewable energy. Not only can it lower your electric bill at home, but it's also a great choice for generating electricity at cabins and worksites far from existing power lines. With compatible equipment, Sunforce wind generators can even be paired with solar panels for additional, diversified power creation.


Sunforce wind generators are easy to set up and operate.
Convenient Power That Helps You Save Money and Protect the Environment
On land and at sea, people have been harnessing the power of the wind for thousands of years. With the Sunforce 44444 12-Volt 400-Watt Wind Generator, you can use the power of the wind to provide energy for your home, cabin, worksite or remote equipment. Wind power can help cut your energy bills by reducing your dependence on the main electrical grid at home, and is also ideal for many remote locations that are far from existing power lines. Unlike nuclear and fossil fuels, wind power systems are clean and pollution-free, and they require little maintenance to operate.


Wind power can significantly lower your electric bill.
Flexible Power for New or Existing Systems
The Sunforce 44444 12-Volt 400-Watt Wind Generator is an ideal addition to many new and existing renewable power systems. It provides up to 400 Watts or 27 Amps of power at maximum efficiency. The fully integrated regulator automatically shuts the unit down when the batteries are charged to minimize wear.

The Sunforce 44444 12-Volt 400-Watt Wind Generator features a durable aluminum body and lightweight carbon fiber blades that are optimized for maximum efficiency and low noise. It is completely weatherproof, and the patented high-wind over-speed technology keeps the unit safe in high wind and stormy conditions. Assembly is required, but this generator installs easily and mounts to any sturdy pole, building, or the Sunforce 44455 Wind Generator 30-Foot Tower Kit.

About Wind Power
The Sunforce 44444 12-Volt 400-Watt Wind Generator can provide an average monthly output of 38 kilowatt hours with an average 12 mile-per-hour wind speed. It requires an 8 mile-per-hour wind speed to start generating power. As the local wind speed increases, so does the power output. Since this type of generator uses wind as "fuel", it is important to choose an appropriate site. The ideal location for a wind generator is 20 feet above any surrounding object within a 250-foot radius. Wind speed increases with height above ground, so a taller mast can provide significant gains in energy production.

Wind generators convert the mechanical energy of their spinning blades into an electric current; they do not actually store power. Sunforce Wind Generators are primarily used to recharge all types of 12-Volt batteries, including lead-acid automotive batteries, deep-cycle (traction type) batteries, gel-cell batteries, and heavy-duty (stationary type) batteries. When using this wind generator to run appliances on a regular basis, the use of deep-cycle marine batteries is recommended. This type of battery is designed to withstand the frequent charge and discharge cycles associated with wind power use. Attempting to run the wind generator on an open circuit without a battery may cause damage to the generator or connected equipment.

Great Product Better Than I Expected
 
Review Date: September 27, 2008
Reviewer: R. Martinez, Dolan Springs , AZ
I have this wind generator hooked up to
8 6 volt deep cycle batteries powering my 2 bedroom
off grid home. we run 2 televisions dvd players and compact
flourescent lights for bedrooms and kitchen without
having to turn on our generator. We dont have a microwave,
and our refrigerator runs on propane. But after using our loud
generator for 2 months at $15.00 for gas on a daily basis, The machine
will pay for itself quickly, The noise is minimal.The sounds it makes reminds me of birds chirping. You could not use it to run vacum cleaners
washer dryers and things like that but if you need a little energy for
lighting and small appliances this wind generator is great.

Well I bought this for my fish house and it works great. I bought the stop switch and AMP meter as a extra purchase, but it was a great add on. The product directions are quite detailed and explain everything excellent.

Best deal in town

This is my 2nd one that I purchased for saving electrical power.When it moves, you don't hear it.it is Just a wisper.One windy day can charge my 12 volt batterys.Follow the instructions and you have it made.I give it a 5.
great, very easy to install and set up

I mounted my wind generator to the top side of the house that I am renting. The house happens to be in an area where there is a lot of wind on windy days. I did have some problems finding materials to mount to the side of the house. I could not find a 2" O.D. tube that the generator would fit onto. I did find a 1-3/4" O.D. tube that is used for electrical purposes. The tube is galvonized steel, light weight. I used some gasketing to make up the 1/4" that was needed to securely fasten the generator to the tube. I then cut an extension cord and wired one end to the leads on the generator. I ran the remaining 50' into the basement through a hole in the foundation that I drilled. The generator spins up and works! I am waiting for a windy day to start generating some electricity :)

Product Description

Aerodynamics of Wind Turbines is the established essential text for the fundamental solutions to efficient wind turbine design. Now in its second edition, it has been entirely updated and substantially extended to reflect advances in technology, research into rotor aerodynamics and the structural response of the wind turbine structure.

Topics covered include increasing mass flow through the turbine, performance at low and high wind speeds, assessment of the extreme conditions under which the turbine will perform and the theory for calculating the lifetime of the turbine. The classical Blade Element Momentum method is also covered, as are eigenmodes and the dynamic behavior of a turbine. The new material includes a description of the effects of the dynamics and how this can be modeled in an aeroelastic code, which is widely used in the design and verification of modern wind turbines. Further, the description of how to calculate the vibration of the whole construction as well as the time varying loads has been substantially updated.

This is the essential reference for both engineering students and others with a professional or academic interest in the physics and technologies behind horizontal axis wind turbines.
