Vertical Axis Wind Mill By Using Gearless Technology

develop such wind mills which gives output at low height effectively, we are going to design vertical axis wind mill which works on gearless technology. Prior to the implementation of vertical axis wind mills with gearless technology, power generation from wind is done by horizontal axis wind mills with gear box or vertical axis with gear box.
