wind power; rational energy into electricity?

buildwindgenerator — Fri, 15 Oct 2010 12:52:58 +0000

how does wind power work?
i know that
the turbine blades capture wind energy and start moving,
they spin a shaft that leads from the hub of the rotor to a generator
The generator turns that rotational energy into electricity.

but how does the generator turn the rotational energy into electricity?

please include a reference if you can.
thanks

How do places with wind and solar energy sustain their power?

buildwindgenerator — Tue, 21 Sep 2010 05:41:57 +0000

Some places rely on solar and wind energy right? To power their homes and such. How do they use energy in the night or when there is no wind? Do they have something that stores the energy like a big battery or something?

I have to “make” a green city and it will use renewable energy source including solar and wind energy. How would I make the wind and solar energy sustainable and not have shortages of power?

“Wind Turbine” “VAWT” “Wind Gin” Long Version

buildwindgenerator — Wed, 01 Sep 2010 07:26:45 +0000

“VAWT” “Wind Turbine” Feel “free” to use any of these “concepts” in your “windmill” designs. The wing or plate that swings on a vertical rod has been around forever and the rest are just “conceptual designs” that I came up with. An engineer proficient using AVIs stress analysis application could determine structural integrity issues using these drawings. Who knows; maybe someone will perfect this “design concept” and build them to the same height as the large HAWTs. I (think) “Vertical Axis Wind Turbines” have the leverage potential to produce more power at lower wind speeds. I am amazed by the large HAWTs and many of the modern VAWTs but I hope that engineers, innovators and last but not least, financial risk takers will continue to find ways to lower the required wind speed. Constructive comments are welcomed. If you do not have any, Yes We Can! works for me. Thanks for viewing.

Make Electricity From Wind

buildwindgenerator — Thu, 14 Jan 2010 13:32:41 +0000

Wind turbines are often used to make electricity from wind.

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.

Wind is a powerful source of energy that has been harnessed for different uses for centuries. More and more scientists and researchers feel that wind can be used effectively as a renewable energy source and this can be done only when power within the moving air can be harnessed properly.

The Wind Energy Industry has grown rapidly since the 1990’s and is considered as one of the fastest growing sectors in the power generation industry. Some of the European countries have even installed wind turbines that have been in operation for almost 20 years now and this entire operation has been extremely successful as well. Using wind turbines to harness wind power to create energy have brought down the production costs and are viable option for the coal fired power stations.

According to a study, the UK has the largest potential wind energy resource in the entire Europe and hence wind is being regarded their most promising future source of renewable energy technologies. As of today the wind turbines in the UK are producing electricity that is being delivered to almost 380,000 households and reaching around 1 million people. A salient point of the use of wind energy is that it has reduced carbon dioxide emissions by almost 1.49 million tones per annum.

The question is how can wind be converted into energy? The answer is: by using a wind turbine. The wind turbine is basically a type of rotating device just like a huge fan that can convert the kinetic energy present in the wind into mechanical energy. When this mechanical energy is used by any type of machinery like a pump then such a machine is known as a windmill. If the same mechanical energy is converted to electricity then the machine that does the conversion is called a wind generator or a wind turbine. It is also known as a wind energy converter (WEC) or a wind power unit (WPU).

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 2700 windmills were installed to provide the much needed mechanical load to pumps and gave a peak power of 35MW.

Why turbines should be used to make electricity from wind

Wind turbines can effectively help in creating mechanical energy, which can be used for multiple purposes including assisting in the generation of power and electricity. Some of the other uses include:

One of the salient points is that there is only a one time installation cost after which the electricity that is produced using a wind turbine will be free.
It is a source of clean renewable energy that will not generate any greenhouse gases or emit carbon dioxide or even produce any dangerous wastes.
Each unit of electricity produced by a wind turbine displaces one from every conventional power station. Wind turbines have been commissioned in the UK and have been extremely successful in prevent the emission of almost one and a three-quarter millions tonnes of carbon dioxide every year.
Wind is a reliable and abundant source. UK being the windiest country in Europe has abundance of wind energy that can be used for making electricity.
Wind power contributes significantly to the overall energy generation in any country. Denmark is one of the countries that gets almost 20% of its electricity from wind power
Wind turbines use an extremely robust technology that is designed for operation locally as well as remotely and requires only periodic maintenance.

Wind turbines might be the answer for larger wind projects. For house owners there are diy kits that can be an alternativ when you are going to build wind generator.

Windmill Design

buildwindgenerator — Sat, 10 Oct 2009 07:46:13 +0000

What really constitutes windmill design?

You could say that a windmill is device that converts wind energy into mechanical energy which is later converted into electrical energy. A windmill typically consists of the following parts:

The blades – A windmill can consist of any number of blades from four to 20. Some special wind mills have higher number of blades.
The tower – The tower holds the rotating blades high up in the air so that the winds rotate them.
The shaft – The shaft is responsible for joining the blades with the tower and for the smooth rotation of blades.
The generator – The generator is what generates electricity from the mechanical energy. It also stores power for future use.
The base: The base of the windmill keeps it grounded to the earth.

What factors affect windmill design?

There are many factors that affect the design of a windmill. Let’s understand the major ones:

Wind speed: The wind speed can be accurately measured with the help of an anemometer. It is not possible to determine the right kind of wind mill without knowing the accurate wind speed.
Wind direction: For designing a windmill, it is also important to know the direction from which the wind flows most of the time.
Change in wind speed: Apart from the constant speed of mind, it is required that you know how the wind changes its speed.
Change of wind direction: The direction of wind will not be constant, so it important to note the way it changes its direction.
Obstructions on the site: It is best t install a windmill at a place without many obstructions. Look out for existing and potential structures that may affect the performance of your windmill.
Wind turbulence: The movement of wind is not always predictable. However, it is a good idea to understand the patter of wind turbulence in your site.
Distance of wind activity from the ground: The height of the tower is dependent on the height at which the wind is active.

What are the possible designs of windmills?

Aerodynamics determines the design of a windmill based on the factors mentioned in the section above. The designs of windmills vary in the following measures and of most importance when you build wind generator:

Number of blades
Shape of the blades
Height of the tower
Kind of generators
Distance of the installation spot from the ground
Distance between the tower and the generator
