Patent ID: 8453665

Claim:
A method for continually circulating a fluid in a sealed, closed system in the absence of an external pumping mechanism, the method comprising: a) providing a sealed, closed system without an external pump or pressure-providing mechanism, the sealed, closed system including: i) an active space; ii) a passive space; iii) a porous medium disposed between the active space and the passive space, the passive space surrounding the porous medium; iv) a fluid filing the active space and the passive space; and v) a shaft, the active space being confined between the shaft and the porous medium, the shaft being under a load and in an eccentric position relative to the porous medium, the shaft defining a convergent and divergent zone in the active space; and b) rotating the shaft, thus generating a pressure differential relationship between the active space and the passive space causing the fluid to move out of the convergent zone of the active space and into the passive space, and then out of the passive space and into the divergent zone of the active space, thus causing the fluid to circulate freely in both directions between the active space and the passive space, across the porous medium, such that the fluid circulation defines a self-acting, self-circulating fluid system.
