Abstract: Systems and methods for a single-body point absorber buoy with a rigid body housing a multi-stage hollow cylinder, a multi-thread high helix shaft, a low rounds-per-minute permanent magnet alternator/generator, damping/heave plate and cooling and communication tower.

Abstract: The present invention depicts a reciprocating engine actuated by means of anaerobic fuel comprising a piston reversibly actuated inside a cylinder in an N-stroke operation, the piston being in communication with a crank; a feeding means adapted to introduce the anaerobic fuel to a cylinder head accommodating at least one piston and cylinder, in at least one event of each of said N-stroke; an ignition means igniting the anaerobic fuel in or adjacent to the cylinder head, whereat the piston is in at least one predetermined location in the cylinder along each of the N-strokes, so that in each stroke, a predetermined deflagration of the anaerobic fuel is actuating the crank.

Abstract: The present invention discloses a turbine assembly (20b) driven by predetermined deflagration of anaerobic fuel. The use of anaerobic fuel enables operation without any necessity for an additional oxidant, and leads to more efficient and environmentally friendly turbine operation. In addition, the gaseous products of the deflagration can be used for any number of purposes after they have passed through the turbine, e.g. combustion of the inflammable portion can drive a second turbine stage (214, 216) or be used to heat air or water.

Abstract: An apparatus and method for in situ gas-phase formation and deflagration of nitrocellulose. A nitrating agent such as nitric acid and cellulose are delivered separately to a reaction chamber, where a brief heating pulse initiates nitration of the cellulose and deflagration of the nitrocellulose thus produced. Discharge of the high-pressure gases produced by the deflagration from the reaction chamber can then be used to drive an actuator, turbine, etc.

Abstract: The present invention provides an absorbing pad for indicating saturation. The pad comprises inter alia from at least one absorbent body, at least one saturation sensor embedded within said absorbent body and at least one saturation indicator connected to said saturation sensor, embedded within said absorbent body wherein said indicator is adapted to provide information to the user as to the degree of saturation of said pad without removing the pad from its application.
