Patent ID: 7380974

Claim:
A method of initiating cavitation within a cavitation fluid within a cavitation chamber, the method comprising the steps of: retracting a cavitation piston coupled to a hydraulic driver and coupled to the cavitation chamber, wherein said cavitation piston is retracted from a fully extended position to a first partially withdrawn position; isolating the cavitation chamber; magnetically coupling an impeller assembly within the cavitation chamber to an impeller drive system, said impeller drive system external to the cavitation chamber; rotating at least one impeller corresponding to said impeller assembly with said impeller drive system, wherein cavitation fluid within the cavitation chamber rotates in response to said impeller rotating step; retracting said cavitation piston from said first partially withdrawn position to a second withdrawn position, wherein said second withdrawn position is further withdrawn than said first partially withdrawn position, and wherein at least one cavity is formed within the cavitation fluid within the cavitation chamber as a result of said step of retracting said cavitation piston to said second withdrawn position; and extending the cavitation piston from the second withdrawn position, wherein said extending step is performed until at least one cavity is imploded as a result of said extending step.
