1. A method of using a turbine generator system, comprising:
- pumping a working fluid in a Rankine cycle from a low pressure reservoir toward at least one commercial compressor interstage cooler;
heating the working fluid from the heat energy recovered from one or more compression stages of the commercial compressor interstage cooler, at least a portion of the working fluid being pressurized and heated to a gaseous state;
directing the heated and pressurized working fluid toward a turbine generator apparatus, the turbine generator apparatus including an inlet conduit to direct the working fluid toward a turbine wheel that is rotatable in response to expansion of the working fluid;
generating electrical energy from the rotation of the turbine wheel, the turbine wheel being coupled to a rotor of an electrical energy generator that rotates within a stator of the electrical energy generator.

Abstract
Some embodiments of a generator system can be used with the working fluid in a Rankine cycle. For example, the generator system can be used in a Rankine cycle to recover heat from one of a number of commercial applications and to convert that heat energy into electrical energy. In particular embodiments, the generator system may include a turbine generator apparatus to generate electrical energy and a liquid separator arranged upstream of the turbine generator apparatus.
