TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: In the system (I): the component comprises a stator electrical winding, a stator end turn, a radial magnetic bearing, an axial bearing and/or a sensor assembly (141); the underlying component is wrapped with cloth, where the encapsulant is disposed on the cloth; the encapsulant comprises a filled epoxy encapsulant comprising at least 50 wt.% of mechanically reinforcing fillers; the encapsulant is configured to withstand exposure to the organic working fluid at a temperature of at least 150-250 degrees C; and the component is impregnated with a varnish configured to withstand exposure to the organic working fluid. The system (I) comprises: a first organic Rankine cycle system comprising the generator and configured to circulate the organic working fluid through a cycle of expansion and pressurization; and a second organic Rankine cycle system disposed in a cascade configuration with the first organic Rankine cycle system. In the system (II): the generator is configured to direct the flow of the organic working fluid through the generator between the stator and rotor; the electrical winding end turn is impregnated with a varnish configured to withstand exposure to the organic working fluid; and the electrical winding end turn is wrapped in an electrical grade fiberglass cloth disposed between the electrical winding end turn and the encapsulant, where the encapsulant comprises a filled epoxy encapsulant comprising at least 60 wt.% of mechanically reinforcing fillers. The system (II) comprises a radial magnetic bearing (128) configured to support the permanent magnet rotor, where the radial magnetic bearing comprises electromagnetic coils encapsulated with the encapsulant and the electromagnetic coils are impregnated with a varnish configured to withstand exposure to the organic working fluid. Preferred Method: In the method, the component comprises a stator, where injecting the encapsulant comprises injecting the encapsulant into an interior of an end turn of the stator and towards an exterior of the end turn. The method comprises: impregnating the component with a varnish prior to disposing the component within the mold; and installing the component within an integrated power module comprising the generator.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: In the system (I), the organic working fluid comprises toluene, cyclohexane or a nonpolar organic solvent with a lower solubility than cyclohexane, where the solubility is quantified by a Hildebrand solubility parameter.
