This compilation first describes a system wherein a high-nuclear high-temperature reactor supplies constant power to a thermal energy storage unit of molten lithium chloride salt, which provides the required thermal energy for a closed energy conversion system. Next, a compact power generation-storage system is constructed using a direct current-alternating current inverter, spherical Si solar cells, and a lithium-ion battery integrated into a single module. The authors discuss how, since a number of different countries' electric power utilities are adding capacity, there is an opportunity to introduce a new, longer-lasting design for a wind turbine system. A method to reduce the consumption of high-pressure steam and cool fluid in the ethanol process is presented, as well as a plan to reduce the emission of environmental pollutants from the H-501 furnace in the maleic anhydride process. Energy optimization is carried out for the condensation stabilization component of Ilam gas refinery. The closing study focuses on techniques such as the adjacent tree-bounded hop algorithm that may be used to reduce the energy consumption of wireless sensor networks, whether static or dynamic.
