- The Stall Flag: An optical detector to visualise stall on full scale objects in the field such as wind turbines.
- The Corotorq: An anemometer which measures wind speed more accurate and measures wind direction too.
- 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.
- Controlling Wind: A fundamental new way to increase the yield of a wind farm.
- Heat and Flux: A second fundamentally new way the optimize a wind farm.
- Slender Blade: A blade design increasing the yield between 6% an 10% at the same loads.
- Top Induction Tip: a wind turbine blade with extreme small chords in the tip range leading to a higher yield/cost ratio.
- Twisted Blade Root: a wind turbine blade using thick airfoil, high twist and a segmented blade root strip.
- Corten Vortex Generator: the first CFD optimized and wind tunnel approved vortex generator with a much higher performance than the conventional triangular fins.
- Controlling Wind: Method to improve energy capture by wind farms by generating large scale atmospheric circulations in and above farms.
- Heat and Flux: A Method to increase the yield of 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.
