| This is the modified version of the low cost bamboo windmill with the advantage of changing its direction with the change in the direction of wind. The main components of the windmill are mainframe or structure, blades with tail and a crank mechanism for converting the rotary motion into reciprocating motion. A simple mechanism is used to make the windmill multi directional. At the top of the mainframe a simple arrangement is made to rotate around vertical axis with the help of roller and cylindrical bearing. This multi-directional rotating frame carries the blades, shaft and crank mechanism. In the present design we have directly connected the crank mechanism with the rod which in turn is connected to the cylinder at the bore. Blades are given the proper angle so that the higher wind power can be harnessed and there by can pump the water from greater depth. Blades are made up of aluminum sheet or MS angle. Wires are used to provide the extra strength to the blades. |

| Current Status: |
| Installation in North East Area: Innovator Shri Mehtar Hussain has installed about 7 units in North East region. Centre for Energy, Indian Institute of Technology Guwahati has done the technical analysis and feasibility study in the year March 2007. The copy of the report is enclosed herewith in Annexure: 1. As per the report, the performance of the wind turbine installed at Mahariapathar was found to be the best giving a maximum discharge of 60 liter/min at 3.2 m/s. In the report, the scientist also made recommendation to increase the performance of the wind mill. |
We need the support of interested individuals / entrepreneurs / organizations in building total value chain for promoting this useful innovation in order to diffuse this technology to the real end users. For any furrier information, please contact: |
