The ball of the sphere type with peripheral channels spaced and intersected at distances on the surface, with part of the flow on the front over pressure area communicating with the rear depression of the ball in its forward movement, facilitating aerodynamic air circulation through it and so reducing resistance and allowing its rotation and lift, enhance the advance, that consists in a sphere whose surface is covered by multiple peripheral channels intersected which determine equal spherical triangles. Through orifices may be added through the ball and parallel to tangents to it, crossed over and inter-communicated on different planes, and which form curved interior ducts facilitating the internal circulation of the air as the balls turns. <IMAGE>
