Kites have several advantages over other technologies to harvest wind energy, such as for instance sails, Flettner rotors, or rotating wind turbines. All these “old technologies” have in common that they are attached to masts, which develop torque at their base, leading to scaling problems.

• One advantage is that a kite can make use of higher wind speeds of higher altitudes. A kite can harvest wind at 100m – 800m altitudes and more. Wind turbines harvest averaging at 80m – 120m. Sails and Flettner rotors even less.
• Kites develop no torque to the point to which they are attached. Therefore there is only little heeling to a ship’s hull. The torque, which sails exert on their base, such as a ship hull, often limits their size. Same with the masts of wind turbines. Kites do not have this problem, which means that the size of the kite is theoretically unlimited.
• A kite can actively fly through the air. The surface on which a kite flies is also called the flight envelope or the wind window. An actively flying kite increases the true air speed at the kite. It leads to enormous power output. Please keep in mind the cubic relationship between power and wind velocity as described here: solution requires to go far offshore >>

In summary a kite is much more effective than alternative methods to harvest wind energy and therefore superior. This, in combination with harvesting in strong and permanent wind will lead to low-cost hydrogen in large quantities.
