A scent vaporizing and distribution device uses an electric heating element to rapidly vaporize a liquid scent material. An airflow generator is used to create a distribution airflow that distributes the vapor from the device. The airflow generator can be an electric-powered fan or a manually-powered pump or squeezable bladder. The liquid scent material can include a glycol or a water-glycol mixture. A scent material such as liquid or powdered deer urine or a pleasant scent that can be used as a room or automobile or room freshener is mixed with the liquid. The vapor generator can be removable and replaceable such that different scents can be used with a single airflow generator or an empty generator can be replaced.

A system including an engine and a heat exchanger coupled to the engine is provided. The engine includes an engine fluid and at least one of a compressor section configured to compress a gas, a lubricant path configured to circulate a lubricant, or a coolant path configured to circulate a coolant. The engine fluid comprises at least one of the gas, the lubricant, or the coolant, and the engine fluid is a source of heat derived from one or more operations of the engine. The heat exchanger is configured to receive the engine fluid from the engine and exchange heat between the engine fluid and a working fluid to produce a heated working fluid and a cooled engine fluid, and the heat exchanger is configured to export the heated working fluid to a steam system.

An improved closed loop Brayton cycle for a power plant is provided that includes a heater, at least one turbine, a recuperator, at least one cooler, at least one compressor, a bypass line and a flap valve arrangement in a closed circuit in which working fluid is circulated to produce electricity via a generator. Depending upon the requirement, such as, in case of gird load disconnection, speed of a shaft-line to which the turbine, the compressor and the generator are configured is also required to be reduced without any impact on the pressure drop in the cycle. For that the non-tight flap valve arrangement is configured on each conduit between the heater and the at least one turbine in a closest possible proximity to each turbine inlet.

A generator uses a working fluid in a single-cycle Rankine engine for up to three purposes: generation of electricity; generation of hot water from heat exchanger; and generation of chill by the evaporation of liquefied working fluid. The working fluid, which may be carbon dioxide, goes through a single Rankine cycle for both heat engine and heat pump. Instead of using a pump to liquefy the working fluid, the working fluid experiences cryogenic liquefaction method under controlled pressure. The Hui turbine is used for electricity generation. Heat source for the combined heat pump and heat engine could come from concentrated solar power or from burning a fossil fuel.

A solar heat turbine system includes: a compressor which compresses a working fluid, and generates a high-pressure working fluid; a solar heat receiver which heats the high-pressure working fluid with solar heat, and which generates a high-temperature working fluid; a turbine which is rotationally driven by the high-temperature working fluid; a restriction mechanism which restricts a flow of at least one of the high-pressure working fluid and the high-temperature working fluid; a rotation interlocking mechanism which rotationally drives the compressor so as to interlock with the turbine; a bleed mechanism which causes the high-pressure working fluid which is in a process of being generated in the compressor to be bled as a bled working fluid; and a system control unit which causes the bleed mechanism to execute bleeding after the restriction mechanism is caused to restrict.
