Definitions

• the invention also extends to apparatus for producing localised concentration of energy comprising: means for providing a series of projectiles, means for firing said projectiles at a target configured such that upon striking said target, said projectiles trap a volume of gas between the projectile and the target, the target and projectile further being configured such that impact of the projectile onto the target gives rise to a converging Shockwave inside the trapped volume of gas.
• the projectiles could be solid or semi-solid e.g. a gel or a polymer, or any material that can be accelerated to suitable speeds, entrap a gaseous volume on a surface and generate the energy density focussing mechanisms described above for pressure and temperature intensification.
• the projectiles comprise droplets of liquid.
• the liquid droplets are produced by the apparatus described in US 7380918.
• the projectile will typically need to be moving fast enough to generate the
• the target structure might take in order to provide suitable regions for entrapment of a volume of gas when struck by a projectile and which give rise to a converging Shockwave into the trapped gas.
• the target comprises a concave surface shaped so as at least partially to receive the projectile and trap said gas beneath the projectile.
• the term "beneath” used here should be understood in the frame of reference where the projectile approaches the target from above; no particular spatial orientation relative to any other object or gravity should be inferred. Moreover it should not be inferred that the projectile necessarily approaches the target in a perpendicular manner in the frame of reference of the target.
• a concave target surface accommodating the projectile; and a target surface having one or more smaller, discrete depressions, are not mutually exclusive.
• a target surface might be concave so as at least partially to receive the projectile, whilst also comprising one or more discrete depressions.
• Such combination could be beneficial in providing the desired behaviour of the Shockwave generated inside the projectile, whilst also enjoying the advantages of compressing a plurality of volumes of gas.
• the methods described herein are employed to generate nuclear fusion reactions.
• the fuel for the reaction could be provided by the droplet, the trapped gas bubble, or the fuel could be provided by the target itself.
• the apparatus can be used by firing a stream of very high velocity droplets, e.g. of water, by producing a stream of liquid which is then broken up using the apparatus described in US 7380918.
• the droplets have a diameter of approximately 150 microns, travel at a speed of approximately 1 kilometre a second and are produced at a frequency of approximately 1 Megahertz. In computational modelling, this gave rise to a peak pressure of 4.6 x 10 9 Pascals which is sufficient to cause temperatures in excess of 1 x 10 6 degrees C which can be sufficient for a nuclear fusion reaction of the deuterium atoms.
• the resulting neutrons can either be used in other processes or, in one example, may be absorbed by a neutron absorber for conversion of the kinetic energy of the neutrons to thermal energy and thus conventional
