The opposing wind forces are completely neglected with the help of a deflector such that the speed of the turbine shaft is increased faster than normal, even at very low wind speed (1m/s). Almost all the wind turbines extract only 50 to 60% of total wind power due to low speed. This is due to the wind resistance in the blades.
