Abstract

Domestic renewable power plant is important for the reduction of world’s CO2 emission. Micro-wind turbines based domestic power generation is still new technology and has many challenges including high capital costs and performance issues. The technical challenges are mainly to overcome the high frequency of changes of wind direction. The unpredictable and low wind velocity and high turbulence flow which are very site specific. It is well known that several factors affects the degree of performance enhancement of wind turbine like blade airfoils and the wind direction at mounting site. The take up of micro-wind turbine based power generation can be simulated if the device can be made to produce power in difficult wind conditions encountered in built environment and alternative utilization of technology can be developed. Windlens turbine can help overcome these problems. This windlens turbine has a brimmed diffuser around the turbine rotor, which is referred to as windlens. The windlens can achieve wind concentration on the turbine rotor, resulting in the significant enhancement of turbine output increasing the wind velocity at the vicinity of the rotor, hence increasing the power output compared to present day wind turbines.
