A water navigable vessel or glider can transport cargo across oceans and other bodies of water without the use of fossil or nuclear fuels. The vessel includes a housing, a cargo or payload area within the housing, one or more control fins attached to the housing, a ballast within the housing, an expandable and contractible container configured to receive a clathrate and maintain a minimum amount of pressure on the clathrate within the housing in proximity to the ballast, and an intake valve coupled to the ballast. The clathrate changes state, thereby changing the buoyancy of the glider, and causing the glider to move through the body of water. |

A combined heat power system comprises a Rankine cycle, optionally an organic Rankine cycle, using a fluid both in gaseous phase and liquid phase. The Rankine cycle comprises —an evaporator for evaporating the fluid from liquid phase to gaseous phase, an expander for expanding the fluid in gaseous phase provided by the evaporator. The expander is suitable to transform energy from the expansion of the fluid in gaseous phase into mechanical energy, —a condenser for condensing the fluid from gaseous phase from the expander to liquid phase and —a liquid pump for pumping the fluid in liquid phase provided by the condenser to the evaporator. The system comprises a heat source providing exhaust gas. The exhaust gas provides thermal energy for evaporating the fluid from liquid phase to gaseous phase by the evaporator. The system further comprises a generator unit for converting mechanical energy from expander to electrical energy. The expander is a volumetric expander. |

A system that is used for recuperating, increasing and generating energy that is inherent within a heat source. Any type of heat source can be utilized such as “ambient air” which is preferred, or the like. The system incorporates fluids namely, a liquid refrigerant and hot oil. The unusual new end results are accomplished when the liquid refrigerant and hot oil are mixed together resulting in a physical reaction that produces intense (P.S.I.'s) and highly pressurized foam which in turn provides lubrication and produces usable energy that can be used to power the system and/or transferred to a rotary shaft for work. Also, the system may be easily used for refrigeration or air conditioning purposes. |

A high efficiency vapor (steam) engine/pump process in a closed system can use either water or liquefied gases for its working fluid to extract thermal energy from the ambient or non-ambient heat sources to increase its heat transfer rate and obtain power generation efficiency over 50%. A slow-speed two-phase piston engine's flywheel has a high ratio gear reducer attached to increase a generator's speed and produce power with over 50% efficiency and meet its power generation requirements (3,600 RPM). This two-phase engine/pump substitutes the cooling condenser's position, compresses the waste streams directly back into the boiler, and allows the process to run at temperatures lower than room temperature, with no need for a conventional cooling condenser. The present process will not discharge thermal pollution and/or radioactive/hazardous wastes into the heat sink and to the global environment, which is highly recommended for new nuclear steam engine modifications. |

It is an object to provide a fluid machine, which is simple in structure and in which lubricating oil containing smaller amount of the working fluid is supplied to sliding portions of an expansion device. The fluid machine has the expansion device for generating a driving force by expansion of the working fluid, which contains the lubricating oil and is heated to a gas phase condition. The fluid machine further has an electric power generating device driven by the driving force of the expansion device and generating electric power. An oil pooling portion is formed in a fluid passage, through which the working fluid discharged from the expansion device flows, such that the lubricating oil contained in the working fluid is brought into contact with at least one of sliding portions of the expansion device and the electric power generating device. And a heating unit is provided to heat the working fluid in the oil pooling portion. |

The conduit has a compression section extending generally radially from the shaft, a combustion section extending generally axially and parallel to the shaft and from the compression section at a radial distance from the shaft, and an expansion section extending from an end of the combustion section remote from the compression section. The bubble nozzles are located before the inlet of the compression section. |

A de facto wall-less heat exchanger system wherein a non-volatile heated liquid from a nuclear, geothermal or other source of heat is introduced into a chamber containing a highly volatile fluid which is chemically non-reactive with the non-volatile liquid. The volatile fluid is converted to a pressurized vapor which may be used to drive a turbine for the production of useful energy, to pump the non-volatile liquid or to pump a different fluid. |

There is disclosed herein a throttle valve having an elongated housing and a piston rod carrying an elongated spool and a relatively short spool spaced axially from the elongated spool. The spools are axially slidable within a sleeve which lines the housing. The sleeve has axially spaced apertures of graduated size allowing transfer of pressure from intake to outlet lines, and the elongated spool progressively closes off or opens the apertures when moved axially. The spacing between the spools is such that the intake line is disposed between the spools in any position of the valve to provide equal axial pressure on the spools and stabilize the valve.
