Windgo, a research and development company specialising in smart material and vibrational transfer technologies, has announced that they are expanding their thermal coatings into airflow systems based on multiple patents in their nanotechnology coatings patent portfolio.
Temperature and humidity can cause ice build-up on wind turbine blades that distorts the air flow patterns into a non-ideal flow against the leading edge of the wind turbine blades. The overall effect can cause a reduction in energy output of 20% inefficiency of generated power. By coating the leading edges of a wind turbine’s blades with active nanoparticles a small excitation current can be applied to the coating to start a high frequency vibration that causes a warming effect.
