Abstract
A wind turbine includes two sets of blades. A first set of blades is placed at a front location of the wind turbine. A second set of blades is placed behind the first set of blades. The first set of blades turns in an area within a first circumference. The second set of blades are mounted at a location sufficiently away from an axis of rotation of the wind turbine so that the second set of blades turns within an area that is within a second circumference and that is substantially outside the first circumference.
