PATENT NO:  TR200901001 A2 A slowmo night photography test of HIGH-SPEED VAWT wind turbine "StormDancer". This is a single airfoil design for developing nations. Intended to fight climate change and achieve net zero. Can be manufactured without using expensive specialist composite materials. Minimalist design allows a simple, durable, lightweight VAWT turbine. Lift-based, high-speed revolving-wing VAWT delivers new performance characteristics. https://fastvawt.blogspot.com/2023/01/worlds-first-patented-high-rpm.html?m=0 Engineering explained: the innovative new category of revolving-wing wind turbines use a single wing or airfoil to translate aerodynamic lift force efficiently into a sustained and rapid 360 degree rotation around one rotation axis. Instead of a moving airfoil continuously cutting rapidly through oncoming wind as is the case in most vawt designs, limiting the efficiency of the turbine, a revolving wing wind rotor essentially flips over rapidly in place in wind using aerodynamic lift force and does not move through it. This not only translates into very different mechanical behavior and airflow around the rotor, but also allows revolving wing vawts to eject energy-depleted wind to the sides and create a very different wake from existing horizontal axis and vertical axis wind turbines. An aerodynamically stable revolving wing vawt rotor design creates high energy output, low vibration, low noise and does not have strong pull or push forces acting horizontally on the central shaft it revolves around, resulting in reduced wear on the mechanical components of the wind turbine and thus lower maintenance costs. Another major advantage of this design is that wind turbines of this type can be placed much more closely together than is typically possible with horizontal axis wind turbines. This turbine produces a different wake than is seen in existing hawt or vawt turbines and is less affected by turbulent flow created by a neighboring turbine of the same type. It is thus possible to install more units of this type in a given area than would be possible with existing designs, especially compared to horizontal axis wind turbines. It is also possible to place more turbines of this type together by staggering the height of the installed units. In energy generating offshore windfarms, especially floating offshore facilities where wind turbines are placed on floating pontoons, buoys and/or moored to the sea floor, this design has far less tilting force acting on it than a horizontal axis wind turbine, allowing it to float on water with far less undesired swaying or tilting or propensity to drift. This is due to the rotor design's natural propensity to spin in place with great stability rather than trying to move in any direction the wind pushes in. This revolving wing design may in the future also be adapted for use as a water turbine which can generate electricity from flowing water currents such as in a river, or from moving tides and sea waves. How well this design will perform in water has not been sufficiently explored yet as the prime focus of the design effort at present is on producing clean energy efficiently from blowing wind. To prevent birds or other flying animals from being harmed by this rotor, the rotor, which has a cylindrical rotation envelope, can be surrounded with a thin cylindrically shaped safety netting. This prevents flying animals from entering into the turning area and improves the visibility of the vawt turbine so animals can see it more clearly. The aim of this green energy innovation is to protect the environment, reduce carbon emissions and air pollution and make it more economically feasible for the world to achieve net zero emissions. With more efficient and differently sized vawt windturbines which are suitable for use in areas with turbulent windflow, like cities and wooded areas, this aim becomes one step closer to becoming reality. Living in harmony with nature is only possible when renewable energy becomes cheaper and more economically desirable. This requires new, differently designed energy generators which respect the laws and rules of nature.
