A method for implementing a thermodynamic cycle comprising the steps of: transforming thermal energy from a fully vaporized stream into a usable energy form to produce a lower pressure, spent stream; transferring thermal energy from an external heat source stream to a boiling stream to form the fully vaporized stream; transferring thermal energy from the lower pressure, spent stream to a first portion of a heated higher pressure, basic working fluid stream to form a partially condensed spent stream and a first pre-heated higher pressure, basic working fluid stream; transferring energy from the external heat source stream to a second portion of the heated higher pressure, basic working fluid stream to form a second pre-heated higher pressure, basic working fluid stream; combining the first and second pre-heated higher pressure, basic working fluid streams (6,7) to form a combined pre-heated higher pressure, basic working fluid stream; separating the partially condensed spent stream into a separated vapor stream and a separated liquid stream; pressurizing a liquid sub-stream to a pressure equal to a pressure of the combined pre-heated, higher pressure basic working fluid stream to form a pressurized liquid stream; combining the pressurized liquid stream with the combined pre-heated higher pressure, basic working fluid stream to form the boiling stream; combining a second liquid sub-stream with the separated vapor stream to form a lower pressure, basic working fluid stream; transferring thermal energy from the lower pressure, basic working fluid stream to a higher pressure, basic working fluid stream to form the heated higher pressure, basic working fluid stream and a cooled lower pressure, basic working fluid stream; transferring thermal energy from the cooled lower pressure, basic working fluid stream to an external coolant stream to from a fully condensed lower pressure, basic working fluid stream; and pressurizing the fully condensed lower pressure, basic working fluid stream to the higher pressure, basic working fluid stream. transforming thermal energy from a fully vaporized stream into a usable energy form to produce a lower pressure, spent stream; transferring thermal energy from an external heat source stream to a boiling stream to form the fully vaporized stream; transferring thermal energy from the lower pressure, spent stream to a first portion of a heated higher pressure, basic working fluid stream to form a partially condensed spent stream and a first pre-heated higher pressure, basic working fluid stream; transferring energy from the external heat source stream to a second portion of the heated higher pressure, basic working fluid stream to form a second pre-heated higher pressure, basic working fluid stream; combining the first and second pre-heated higher pressure, basic working fluid streams (6,7) to form a combined pre-heated higher pressure, basic working fluid stream; separating the partially condensed spent stream into a separated vapor stream and a separated liquid stream; pressurizing a liquid sub-stream to a pressure equal to a pressure of the combined pre-heated, higher pressure basic working fluid stream to form a pressurized liquid stream; combining the pressurized liquid stream with the combined pre-heated higher pressure, basic working fluid stream to form the boiling stream; combining a second liquid sub-stream with the separated vapor stream to form a lower pressure, basic working fluid stream; transferring thermal energy from the lower pressure, basic working fluid stream to a higher pressure, basic working fluid stream to form the heated higher pressure, basic working fluid stream and a cooled lower pressure, basic working fluid stream; transferring thermal energy from the cooled lower pressure, basic working fluid stream to an external coolant stream to from a fully condensed lower pressure, basic working fluid stream; and pressurizing the fully condensed lower pressure, basic working fluid stream to the higher pressure, basic working fluid stream.
