Why Kite power system is better than wind blade turbine / Bill Gates about Kite theory

The kite Power system currently building 500kw structure these virgin is use 6m vide cord for comparison and equaling to 500 kw wind turbine have diameter 54 m. Wind turbine blade have to strong enough to resist both rotating motion and bending motion and tower have to be strong enough to bear the weight of blade and wind turbine and also need base support in earth or ocean.

In comparison kite power system main component that significant loading. The ground station simply heavy enough to prevent the kites to lift the kites from the ground. This makes the system significant and cheaper.

The study foundation 2016 by the International renewable energy agency find the cost of per megawatt hour energy generated by offshore is 170$ that is expected to fall in 95$ in 2030.

The study conducted by independent KPS the kite power could generate per megawatt hour in 62.5$ by 2020 and 50$ at 2030 it is significantly reduced the cost of offshore 

Gill gates even said that 

10 percent chance the kite power will be the future magic power for the solution of energy crises

The population is increase day by day so there is essential to produce such systems that can use the renewable sources and provide electric energy.
