FIELD: energy.
SUBSTANCE: invention relates to power engineering. Disclosed is a generator containing a heat differential module, pressure module, conversion module and heat recovery arrangement; heat differential module comprising at least a first, high temperature reservoir configured for containing a work medium at high temperature, second, low temperature reservoir configured for containing a work medium at low temperature and a heat mechanism being in fluid communication with at least one of the reservoirs. Heat mechanism is configured for maintaining a temperature difference therebetween by providing heat to and/or removing heat from the reservoirs; pressure module comprises a pressure medium in selective fluid communication with the reservoirs of the heat differential module for alternately performing a heat exchange process with the work medium thereof. Pressure medium is configured to fluctuate between a minimal operative temperature and a maximal operative temperature of the pressure medium corresponding to the high and low temperature of the work medium of the reservoirs; conversion module is in mechanical communication with the pressure medium and configured for utilizing temperature changes of the pressure medium for the production of output energy; heat recovery arrangement is in thermal communication with the heat differential module and configured for absorbing heat from the pressure medium and providing heat to the heat differential module or to the pressure module.
EFFECT: higher efficiency of heat conversion to electric energy.
