u201c size u201d and a second u201c size u201d consequently in such a configuration the stratum configuration 334 resembles a u201c picket fence u201d in appearance the stratum configuration 334 illustrated in fig3 d is merely illustrative and one skilled in the art will readily recognize that sweep heights may be sized according to additional u201c sizes u201d e g a third size in this way in a stratum configuration such as the stratum configuration 334 illustrated in fig3 d sweep heights of at least two wind turbines of the configuration are sized to intersect at least one horizontal plane unique from horizontal planes intersected by a sweep height of at least one immediately adjacent wind turbine in fig3 e a stratum configuration 344 includes a first wind turbine 346 a a second wind turbine 346 b and a third wind turbine 346 c the second wind turbine 346 b is immediately adjacent to the first wind turbine 346 a and the third wind turbine 346 c presented differently the second wind turbine 346 b is an intermediate wind turbine between two terminal wind turbines namely the first wind turbine 346 a and the third wind turbine 346 c the second wind turbine 346 b has a second sweep height 348 b which intersects a horizontal plane u201c a u201d 350 a the first wind turbine 346 a has a first sweep height 348 a and the third wind turbine 346 c has a third.
