The sight of propeller-like rotating blades positioned high up the pole of a tall horizontal-axis wind turbine (HAWT) may be familiar to many. Often grouped in wind farms, HAWTs provide significant amounts of energy for local communities. One drawback to HAWTs is the large space they take up, needing to be placed far apart from each other. If placed too close together, the turbulence and wind velocity deficit caused by one HAWT can make a neighboring HAWT output much less power.
