A chemical reaction between molten aluminum and an oxygen carrier such as water to do useful work is disclosed, and in particular two chemical methods to obtain aluminum in its molten state. One is to detonate a HE/Al mixture with surplus Al in stoichiometry, and the other is to use an oxidizer/Al mixture with surplus Al in stoichiometry. Additionally, there is a physical method of shocking and heating Al using high temperature reaction products. The produced Al in its liquid form is forced to react with an oxygen carrying liquid (e.g. water), giving off heat and releasing hydrogen gas or other gaseous material. A water solution of some oxygen-rich chemicals (e.g. ammonium nitrate) can be advantageously used in place of water. A shaped charge is also disclosed having a liner that contains aluminum, propelled by a high explosive such as RDX or its mixture with aluminum powder. Some aluminum in its molten state is projected into the perforation and forced to react with water that also enters the perforation, creating another explosion, fracturing the crushed zone of the perforation and initializing cracks. Another shaped charge is shown having a liner of energetic material such as a mixture of aluminum powder and a metal oxide. Upon detonation, the collapsed liner carries kinetic and thermal energy. Also shown are methods to build and to detonate or fire explosive devices in an oxygen carrying liquid (e.g. water) to perforate and stimulate a hydrocarbon-bearing formation.

A wave energy converter (1) comprises a housing (2) extending between a forward end (3) and an aft end (4). Three upstanding air chambers (15) are located in the housing (2) and three corresponding water accommodating ducts (16) extend aft from the air chambers (15) and terminate in aft water accommodating openings (17) for accommodating water into and out of the air chambers (15) as the housing (2) oscillates by pitching in response to passing waves. An air accommodating duct (21) communicates with the air chambers (15) through a manifold (20) for accommodating air into and out of the air chambers (15) as the water level (19a) falls and rises within the air chambers (15) as the housing (2) oscillates.

A means and apparatus for fluid containment providing for closed loop operation of an apparatus within a column of liquid. The apparatus extracts power from a buoyant source within the contained column of liquid and is comprised of an endless chain of movable buoyant objects, a means to convert the movement of the chain into useful work and a tank filled with a constant volume column of liquid. The buoyant objects comprising the chain sequentially enter the bottom of the liquid column through an airlock seal of the current invention, move up through the column and emerge at the surface. The emerging buoyant objects leave the tank and are directed to the tank bottom where each buoyant object repeats the cycle. As the chain of buoyant objects cycles through the displaced column of liquid, the volume of liquid remains constant, with one buoyant object of the chain entering the bottom of the liquid column as one is exiting at the top surface. The invention provides for closed loop operation of the apparatus and increased control fluid flow rates within the apparatus to addresses liquid leakage due to mechanical wear at seals and to provide a controlled method for removal of friction generated heat within the apparatus. Chambered sections within the apparatus create fluid flow restriction zones where differential pressure can be controlled to further reduce the force requirement for injecting each buoyant object (a.k.a. displacing element) into the bottom of the contained column of liquid.
