LOCALISED ENERGY CONCENTRATION
Abstract: A method of producing a localised 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 localised concentration of energy is also provided.
[...] TECHNICAL FIELD
 This invention relates to methods and apparatuses for producing very high localised energies. It relates particularly, although not exclusively, to generating localised energies high enough to cause nuclear fusion.
 The development of fusion power has been an area of massive investment of time and money for many years. This investment has been largely centred on developing a large scale fusion reactor, at great cost. However, there are other theories that predict much simpler and cheaper mechanisms for creating fusion. Of interest here is the umbrella concept "inertial confinement fusion", which uses mechanical forces (such as shock waves) to concentrate and focus energy into very small areas.
