Plastic-powered power generator. In an embodiment, the plastic-powered power generator comprises a primary reactor with an air-fuel distribution assembly configured to supply fluidized polymer, air, and oxidizer to a primary reactor chamber, and an ignition system configured to ignite a mixture of the fluidized polymer, air, and oxidizer. The primary reactor chamber extends into a secondary reactor, to, when ignited, heat air flowing through the secondary reactor from a blower to a heat exchanger. The heated air flow may convert fluid, in a coil within the heat exchanger, into steam, which can drive a turbine to generate electrical power.

A method for generating power from a heat source includes mixing a refrigerant in a liquid phase with a lubricating oil, heating the mixture to evaporate the refrigerant, mixing the heated mixture with additional refrigerant in a superheated phase, and atomizing the lubricating oil to disperse the lubricating oil within the refrigerant. The atomized lubricating oil and the refrigerant are passed through a decompressor to generate an electrical current. The refrigerant may be an organic material having a boiling point below about −35 C. Related systems and heat engines are also disclosed.

In a method of hybrid power generation in an environment with a gas pressure below the earth's atmospheric pressure, liquid water is extracted from a subsurface water ice deposit by pumping superheated-supercritical fluid heated by a heater through an extraction well into the subsurface water ice deposit in order to form a liquid water reservoir. Liquid water is pumped from the liquid water reservoir through the extraction well to the buffer tank. The liquid water is pumped from the buffer tank into a high pressure feeder system (HPFS) and a low pressure feeder system (LPFS), which are each also heated by the heater. The HPFS outputs supercritical water and the LPFS outputs flash steam into a combined injector and the mixture is injected into a turbine at near environmental pressure. This mixture explosively expands into superheated steam and passes through the turbine, powering an electrical generator.
