Wind-mill produced electricity for lighting fish farm shed at mandapam

Abstract

The 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.
