Crosswind Kite Systems

Definition

Crosswind kite systems are innovative airborne wind energy technologies that utilize kites or tethered airfoils to harness wind energy by flying in crosswind patterns, rather than directly into the wind. This approach allows the kites to achieve higher speeds and greater lift, resulting in improved aerodynamic efficiency and enhanced power generation potential. By leveraging the dynamics of crosswind flying, these systems can generate more energy compared to traditional wind turbines.
