Claim:
1. A process for recovering heat from a heat source and generating mechanical energy, comprising the steps of: (a) passing a first working fluid in liquid phase through a heat exchanger or an evaporator, wherein said heat exchanger or said evaporator is in communication with said heat source that supplies said heat; (b) removing at least a portion of said first working fluid in a vapor phase from said heat exchanger or said evaporator; (c) passing said at least a portion of said first working fluid in vapor phase to an expander, wherein at least portion of said heat is converted into mechanical energy; (d) passing said at least a portion of said first working fluid in vapor phase from said expander to a condenser, wherein said at least a portion of said first working fluid in vapor phase is condensed to said first working fluid in liquid phase; wherein said first working fluid consists essentially of a refrigerant consisting of HFO-1336mzz-E, or mixtures of HFO-1336mzz-E and HFO-1336mzz-Z, wherein said mixtures consist of from 64 weight percent to 94 weight percent HFO-1336mzz-E.
