The present invention relates to a power generation apparatus. A power generation apparatus including according to an embodiment of the present invention includes: a main chamber provided with a main space for the accommodation of water, and configured to accommodate water sucked through a suction pipe on the bottom surface thereof; a support part; an auxiliary chamber configured to receive water from the main chamber or to supply water to the main chamber; a pressure pump configured to generate pressure and thus discharge air in the main space out of the main chamber through a discharge pipe provided on the ceiling surface of the main chamber; a spout part configured to spout water, sucked by the pressure pump and accommodated in the main space, out of the main chamber; and a power generation part configured to generate electric power using the pressure of water spouted by the spout part.

A fuel system incorporating a boost pump unit, a boost pump unit and method of pumping fuel are provided. The fuel system and boost pump unit are preferably self-priming and do not utilize an airframe mounted pump for supplying fuel for an aircraft combustor. The boost pump unit includes a liquid ring pump and an air/fuel separator. The air/fuel separator has an inlet and first and second outlet ports. The inlet is operably fluidly coupled to an outlet of the liquid ring pump. The air/fuel separator has an arcuate flow path. The first outlet port is in fluid communication with a radially outer portion of the arcuate flow path and the second outlet port is in fluid communication with a radially inner portion of the arcuate flow path. A return line connected to the first outlet port is configured to return fuel to the liquid ring pump.

An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000 C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. The delivered heat which may be used for processes including power generation and cogeneration. In one application, the energy storage system provides higher-temperature heat to a conventional lower-temperature heat source to boost the temperature of a thermal power cycle working fluid to a turbine, thereby increasing efficiency of the power cycle.
