O-Wind Takes advantage of horizontal AND vertical winds without requiring steering. Apartment dwellers could efficiently/effectively/sustainably generate electricity and independently make use of feed-in tariffs in nearly 80 countries. The turbine is of a spherical shape with a single axis of rotation going through it. Its dimensions and shape mean that it is very suitable for small-scale energy production by individual apartment dwellers e.g. by being fixed outside balconies. The turbine makes use of Bernoulli’s principle for its mechanical motion. The structure is lined up with vents which have large entrances and smaller exits for air. In the presence of wind, there is a pressure difference between the two terminals causing the turbine to move. The vents are placed all across the sphere making it receptive to wind from all directions in both the vertical and horizontal planes. The turbine will rotate in the same sense about a fixed axis regardless of wind direction.
