The present invention is a novel system for generating renewable or pollution reducing electricity. The system does not use burning of hydrocarbons for producing electricity and comprises a heating chamber and a cooling chamber, wherein insulated walls enclose each chamber. The heating chamber contains two or more infrared electric heaters to heat the ammonia in the pipelines that run into and along the heated chamber along with the turbines. Each turbine is configured to be connected to a generator to produce electricity from the stored kinetic energy created by the turbine. The cooling chamber includes an air-cooling device to bring down the temperature of the ammonia vapor and to liquify the vapor. The system improves environmental consciousness by offering a renewable/pollution reducing energy source rather than burning fossil fuels.

Methods, systems, and devices are provided for thermal enhancement. Thermal enhancement may include absorbing heat from one or more devices. In some cases, this may improve the efficiency of the one or more devices. In general, a phase transition may be induced in a storage material. The storage material may be combined with a freeze point suppressant in order to reduce its melt point. The mixture may be used to boost the performance of device, such as an electrical generator, a heat engine, a refrigerator, and/or a freezer. The freeze point suppressant and storage material may be separated. By delaying the periods between each stage by prescribed amounts, the methods, systems, and devices may be able to shift the availability of electricity to the user and/or otherwise boost a device at different times in some cases.

There is provided a steam power cycle system in which steam power cycles using pure materials as a working fluid is used in a multiple stage to reduce pressure loss in the flow channels in the respective heat exchanger so that the fluid serving as heat sources has been caused to make an effective heat exchange with the working fluid. More specifically, not only that the respective flow channels for the fluid serving as heat sources in the evaporator and the condenser in the respective steam power cycle units are connected in series to each other, but the evaporator and the condenser comprise a cross-flow type heat exchanger and are arranged respectively in a flowing direction of the fluid serving as heat source. Consequently, it is possible to reduce the length of the flow channels to the minimum necessary, simplify the flow channel structure, and reduce the pressure loss.
