Abstract
A method of producing a localized concentration of energy including providing a pocket of gas in a non-gaseous medium and in contact with a surface. The surface includes a depression shaped so as to at least partially receive the pocket of gas. A static pressure is applied to the non-gaseous medium, with an average value greater than atmospheric pressure such that the pocket of gas collapses to form a transverse jet. The surface depression is arranged to receive the transverse jet impact such that at least some of pocket of gas is trapped between the impacting jet and the surface depression. An apparatus for producing a localized concentration of energy is also provided.
