INTRODUCTION
Energy is measure of all kinds of work by human beings and nature. So the source is very important to extract the energy.
We can broadly categorize these sources as:
Non-renewable source.
It is a source of energy where the energy extraction is limited for some finite period of time.
Renewable source
It is a source of energy where we can extract energy perpetually.
WHAT IS WIND MILL?
A wind mill is a device for converting wind power to mechanical rotation with a low velocity turbine designed for compressible fluid.
The power in the wind can be extracted by acting on a moving wing, which converts some of that power in to torque on the rotor. The amount of power transferred depends on the wind speed and the mass of air swept by wing.
IMPROVED TECHNOLOGIES IN HORIZONTAL AXIS WINDMILL
Offshore windmill.
Ship with windmill.
The positioning of wind mills is the main difference between the above two.
Though offshore windmill has got high output of 3MW per windmill with wind availability of 97% of time. There is a total loss of 643.4GW of power annually because of non- availability of wind of 3% of time.
This loss can be overcome by using a ship with wind mills by having of wind 100% of time.
CONCLUSION
To reach the high demands of the rapidly developing generation we have to be as efficient as possible. If we are not able to use the freely available air, staying on land, then we have to go in to the sea, face the wind and crab the energy and generate power.
