Vertical mixing means adding a layer of short turbines beneath the tall ones.  Closely spaced H-type turbines produce wakes that are beneficial to a wind farm. The vortices they shed draw speedier wind from higher up toward the vortices.  This faster-moving wind produces more energy from the tall turbines and reduces the distances rows of Wind Harvesters have to be placed downwind from one another. Vertical layering maximizes wind resources and will result in more profitable wind farms and the more intense development of the world’s best wind resources on the same environmental footprint.
