1. A method for generating energy at high efficiencies from an energy source, comprising the steps of:

  • using a thermal generator for heating a pressurized working fluid;

    using a positive displacement expander, having a fixed expansion ratio, for receiving and expanding the heated and pressurized working fluid, as received from the thermal generator, against a reduced pressure sink in order to produce mechanical work;

    using a receiver for receiving and separating a liquid part and a vapor part of the working fluid discharge which exits from the positive displacement expander;

    using an absorber, and a chemosorption process, to absorb the vapor working fluid received from the receiver and to generate a reduced pressure sink at the exit of the expander;

    using a desorber for heating and reconstituting the vapor working fluid from the absorbent liquid produced in the absorber, and provide a resultant vapor working fluid to the thermal generator for reuse;

    using a pump for pressurizing and moving the absorbent liquid produced in the absorber, as the result of chemosorption, to the desorber;

    using a regenerator to recover heat energy contained in a liquid stream received from the desorber, to heat and vaporize the liquid part of the working fluid received from the receiver and provide a resultant vapor working fluid to the thermal generator for reuse; and

    using a pump to transfer the liquid working fluid from the receiver to the regenerator.
