A heat engine is disclosed. The heat engine comprises a housing, a first liquid and a second liquid located within the housing. The first liquid has a higher density and lower boiling point than the second liquid. The heat engine further comprises a heat exchanger which transfers heat to the first liquid to evaporate the first liquid to form a first liquid vapour. The heat engine also comprises at least one fluid flow member which to moves in response to a fluid flow created by the interaction of the first liquid vapour and the second liquid. The liquid-gas phase change of the first fluid provides an alternative mechanism for converting heat into work with numerous advantages. The heat engine has minimal moving parts, a relatively long lifetime, does not require a specific fuel, does not directly release toxic or un-environmentally friendly gases, and can be adapted to a specific source of waste heat.

A power source and hydride reactor is provided comprising a reaction cell for the catalysis of atomic hydrogen to form hydrinos. a source of atomic hydrogen, a source of a hydrogen catalyst comprising a solid, liquid, or heterogeneous catalyst reaction mixture. The catalysis reaction is activated or initiated and propagated by one or more chemical other reactions. These reactions maintained on a electrically conductive support can be of several classes such as (i) exothermic reactions which provide the activation energy for the hydrino catalysis reaction, (ii) coupled reactions that provide for at least one of a source of catalyst or atomic hydrogen to support the hydrino catalyst reaction, (iii) free radical reactions that serve as an acceptor of electrons from the catalyst during the hydrino catalysis reaction, (iv) oxidation-reduction reactions that, in an embodiment, serve as an acceptor of electrons from the catalyst during the hydrino catalysis reaction, (v) exchange reactions such as anion exchange that facilitate the action of the catalyst to become ionized as it accepts energy from atomic hydrogen to form hydrinos, and (vi) getter, support, or matrix-assisted hydrino reaction that may provide at least one of a chemical environment for the hydrino reaction, act to transfer electrons to facilitate the H catalyst function, undergoes a reversible phase or other physical change or change in its electronic state, and binds a lower-energy hydrogen product to increase at least one of the extent or rate of the hydrino reaction. Power and chemical plants that can be operated continuously using electrolysis or thermal regeneration reactions maintained in synchrony with at least one of power and lower-energy-hydrogen chemical production.

A power generating machine system is connected to the thermodynamic field similar to a steam power plant that can be used both mobile and in a fixed manner, which uses fluid liquid nitrogen and/or liquid air mixture and atmosphere air as an energy source. The power generating machine system is not harmful to the environment.

A fluid storage tank can be configured to store a cooling fluid in a liquid state and a gas state. A first heat exchanger can be configured to release heat into the fluid storage tank. A second heat exchanger can be disposed fluidly downstream of the fluid storage tank and configured to exchange heat between the cooling fluid and a heat load. A pressure control device can be disposed fluidly downstream of the second heat exchanger. The first heat exchanger can be fluidly downstream of the second heat exchanger such that cooling fluid, after being heated in the second heat exchanger, passes through the first heat exchanger and thereby heats upstream cooling fluid resident in the fluid storage tank.
