Patents of CortEnergy, with Corten author and inventor.

14-18. Corten Wind Turbine: A a large wind turbine designed to reduce the negative impact of wind energy on both people and nature. Compared to conventional wind turbines, the Corten Wind Turbine offers approximately twice the reduction in all of the following nuisance factors: Cast shadows / Visual impact on the landscape / Noise disturbance / Bird fatalities / Composite waste

13. Slender Blade: A blade design increasing the yield of a wind turbine between 6% an 10% at the same loads.

12. Low Induction Tip: a wind turbine blade with extreme small chords in the tip range leading to a higher yield/cost ratio.

11. Twisted Blade Root: a wind turbine blade using thick airfoil, high twist and a segmented blade root strip.

10, Corten Vortex Generator: the first CFD optimized and wind tunnel approved vortex generator giving airfoils more lift and a better lift/drag ratio compared to conventional vortex generators with rectangular or triangular fins.

Inventions by Corten made as employee of Delft University of Technology and Energy Centre of The Netherlands during his PhD-study at Utrecht University.

9. The Stall Flag: An optical detector to visualize stall on full scale objects in the field such as wind turbines.

8. The Corotorq: An anemometer which measures wind speed and wind direction with a single rotor.

7. The Blade Root Strip: An edge added to the blade root increasing the lift and reducing the drag adding 1-2% to the yield of the wind turbine.

6. Controlling Wind: A fundamental new way to increase the yield of a wind farm by generating large scale atmospheric circulations in and above farms (see the picture).

5. Heat and Flux: A second fundamentally new way the optimize a wind farm: The yield of wind turbines on the upwind side of the farm is lowered slightly with as a result that the production deeper in the farm increases more than the reduction upwind.
