Adv Tech was founded in 2012. We are developing new rotor technologies, determined on the trochoidal movement. These technologies can be applied to thrusters, wind turbines and tidal turbines, with exceptional advantages. Within the company, each has their own specialty and specific skills, but we are all focused on a common objective: to make high-efficiency propulsion and renewable energies cheaper, safer and easier to promote.

> A unique design < CityWind is a cycloidal turbine : a vertical axis, with its blades pitch-controlled during operation. Cycloidal devices already exist, but CityWind is unique. The motion of its blades resembles a natural, oscillating motion. It is based on a unique mechanical concept, and stands out from the other vertical axis. > Safe and user friendly operation < CityWind unique design means it will always operate at low speed. It just cannot go too fast. CityWind will operate approximately 5 times slower than a regular wind turbine. This means it will not overspeed. It will not start oscillating or vibrating. And it will not create any unpleasant aerodynamics noise. Regular wind turbine blades reach a speed of 350km/h. CityWind blades will never go beyond 70 km/h. > High and steady performance < The power created by CityWind rotor is as high as regular screw-like wind turbines. These horizontal axis wind turbine typically have an efficiency of 40%. We demonstrated an aerodynamic efficiency of more than 50%. In addition, the CityWind continues to produce even by turbulent winds. The performance of traditional wind turbines decreases rapidly when the wind is turbulent.
