High pressure vaporizer 121 receives heat from a heat high pressure vaporizer 121 is used to drive high pressure vapor turbine 111. The exhaust or discharge from high pres sure vapor turbine 111 is a loW pressure Working ?uid vapor and may be combined With other loW pressure Working ?uid 30 vapor,asWillbedescribed,andusedtodriveloWpressure vapor turbine 112. The Working ?uid vapor is used to drive high pressure vapor and loW pressure vapor turbines 111, 112. Examples of suitable Working ?uids include, Without limitation, Water, an 151, and transfers the heat to a Working ?uid, thereby pro ducing a high pressure Working ?uid vapor. Alternatively, high pressure vaporizer 121 can receive heat directly from a heat source, such as heat from exhaust gas of an internal 50 havingatleastonemethylradical(CH3)arrangedtoachieve a highly stable compound. Furthermore, the branched iso paraf?ns are highly branched, meaning that they have 3-20 The present technique provides an ability to extract Waste heat from tWo sources.
