Imagine a ball lightning in the form of a charged air stream moving along the trajectories of Villarso circles on the surface of a torus, stretched over a sphere without the northern and southern polar caps. It can be seen that in this case the air flow rises from the South Polar Circle to the North along the outer surface of the sphere, and descends from the North Polar Circle to the South already along the inner surface of the sphere (or vice versa). In addition, it is easy to see that the smaller the radius of the polar circles, the closer the flow paths (i.e., Villarso circle) to the coordinates of longitude. Since the closed trajectories of the charged air flow can be considered as the ring current circuits, the nearby ring current circuits will attract and our polar circles will contract. If the contraction of the poles will be sufficient to initiate the cold nuclear fusion reaction at the poles of the sphere, then we will obtain a mechanism for the formation of ball lightning. As for the mechanism for the formation of the internal symmetry of an electron, here we have a union of the internal symmetries of the torus (shift along the Willarso circle) and rotation of the torus along the surface of the sphere, which generates the SU(2) group. The issue of creating a laboratory ball lightning (as a derivative of an artificial tornado) was raised in the study Deleted research item The research item mentioned here has been deleted
