National Aeronautics Laboratory (NAL), based in Bangalore, is developing a two bladed, stall regulated, 500 kW turbine. It hopes it will be ready by April. NAL's JJ Isaac says the turbine will have a tilt-up tower which will be designed especially for conditions in India. "Larger blades are causing transport problems," he says. "We have developed our own blade shapes and we are working with an industrial partner, Sangeeth Centre, in Coimbatore." The turbine will cost 50% less than others in the market, Isaac says. "Our design is for lower wind speeds as that is what is left of the land available in India," he adds.
