Not AvailableThe concept of using wind energy for producing electricity is not new, though its application in India is of recent origin. A low cost wind-mill battery charger was erected at Pillaimadam lagoon about 5 km from Mandapam Camp, on the southeast coast of India to produce electricity. The wind rotated the blade of the wind-mill to about 800-1000 R.P.M., activating the dynamo which in turn charged the battery. The wind velocity of the coastal area normally ranges from 0-10 km/h. During the northeast and southwest monsoon periods it may exceed 60 km/h. But the normal wind speed is sufficient to attain a R. P. M. of 300-600 which is sufficient to produce electricity.Not Availabl
