Paper [1] shows that, from a purely mechanistic point of view, the charge is proportional to its momentum about the contour of the vortical tube and reflects the extent of non-equilibrium of physical vacuum; spin is proportional to the angular momentum relative to the longitudinal axis of the contour, respectively; and the magnetic interaction between the conductors is similar to forces existing between the current tubes.

The brush is comprised of a core, bristles comprising end portions extending substantially radially around at least a portion of the core, wherein the bristles define a bristled portion of the brush having a first length measured along a longitudinal axis of the core; and at least one notch having a second length measured along the longitudinal axis of the core less than half the first length, with at least one notch defined at a notched bristled portion of the brush.
Key statement: A method and system for generating electric energy in a tire includes a device including a housing that extends according to a longitudinal axis X, at least one electrical winding, a magnet movable within the housing along the longitudinal axis, and a force providing element positioned at at least one of two opposite ends of the housing, which is adapted to exert on the magnet a force along said longitudinal axis.
