How it works
e-kite’s wind power system consists of an ultra-light wing which is connected with a cable to a ground station.
While flying away, the wing is pulling the cable causing a wheel to turn. This wheel then drives a generator to generate electricity. Once maximum cable length has been reached, the wing will dive back to its starting position, after which the cycle starts again. The wing is flying cross-wind circles in order to maximize pulling force and hence electricity production.
The kite power system will generate electricity at >50% lower cost of energy compared to wind turbines of similar capacity for two reasons:
Lower investment costs
Kite power systems do not require heavy, expensive structures such as towers and blades. As a result, the cost price is much lower than that of wind turbines.
Wind energy is harvested at higher altitudes where wind speeds and therefore electricity yields are significantly higher.
Less nimby issues
Kite power systems have less sound and visual impact than wind turbines and they also are less dangerous for bats and birds.
Less resource depletion
Manufacturing kite power systems takes less than 10% of materials needed to produce wind turbines, minimizing depletion of scarce natural resources.
More stable yield
Wind speeds are more constant at higher altitudes, resulting in lower variance in electricity yield and therefore lower balancing costs.
Since kite power systems are mobile, they are suitable for temporary applications and remote sites.
More viable sites
Many onshore sites with lower wind speeds could become economically viable due to the superior economics of kite power technology.
Since our systems can float on pontoons, they can be applied offshore at deep-sea locations.
