Abstract: A power generation system comprising: a liquefied natural gas (LNG) regasification unit configured to perform a regasification process to regasify LNG supplied from an LNG source to produce natural gas, the regasification process producing cold energy; a gas turbine configured to combust the natural gas to output power, the combusting producing an exhaust gas; a thermal storage unit configured to store heat obtained from the exhaust gas; and a Stirling engine configured to output power, the Stirling engine having a hot end heated by the heat stored in the thermal storage unit and a cold end cooled by the cold energy from the regasification process.

Abstract: A ventilator comprising an air blower; a casing comprising a first wall and a second wall configured to house the air blower centrally and to define a radially decreasing volume therebetween, a circumferential gap between the first wall and the second wall configured to allow a high velocity air stream to exit and to spiral in a direction away from a structure to which the ventilator is configured to be mounted, and a central opening in the second wall configured as a suction inlet of the air blower; and a flow amplifier adjacent the casing and configured to amplify air flow through an air flow passage defined between the flow amplifier and the second wall of the casing.
