<DIV>If you don't mind a non-Metric answer, eQuest should fill your needs
nicely. It has reciprocating and gas turbine capabilities, with both jacket and
exhaust heat available in the engine case. The only thing I am unsure of is
taking the exhaust gas from one prime mover and injecting it into another.</DIV>
<DIV> </DIV>
<DIV>It also has quite substantial central plant capabilities as well.</DIV>
