Vertical Axis Wind Turbine ,Insensitive to Wind Direction |
|
“It has been estimated that the total wind power in the atmosphere averages about 3.6 × 1012 kW, which is an annual energy of about 107,000 quads (1 quad = 2.931 × 1011 kWh). Only a fraction of this wind energy can be extracted, estimated to be a maximum of 4000 quads per year. According to what is commonly known as the Betz limit, a maximum of 59% of this power can be extracted by a wind machine. Practical machines actually extract from 5 to 45% of the available power. Because the available wind power varies with the cube of wind speed, it is very important to find areas with high average wind speeds to locate wind machines.” – After solar energy,wind energy was always the second source of free energy.The wind energy conversion principle into electricity through wind turbines represent some disavantages.Changing wind direction and the noise that is produced,leads to death of many birds or other animals.Industri-SA designed some new turbines that can answer all these problems with a clever design. This vertical turbine is designed for urban environments having windy conditions.The axis vertical turbine have a diametre of 8m and a height of 3m.The power produced is up to 175MWh per year and it’s design makes it insensitive with direction and the force of the wind.
