The invention adopts the impeller fluid self-drive method, the fluiddrives the impeller to ensure that the boundary layer brushes rotate without external power;
本发明采用叶轮流体自驱动方式，由流体带动叶轮使边界层刷转动，无需外部动力；

On Earth, heat from the solid inner core drives complex fluid dynamics through convection in the planet's molten outer core, causing an electrical charge which generates a global magnetic field.
Synchronous motor drives the outer cylinder to rotate to shear the fluid, and the cylinder passes the viscous force to the inner cylinder that connects to a circular shaft.
