Abstract
He is disclosed a heat scavenging system for recapturing waste heat from an internal combustion engine having a water cooling system and an exhaust system. The heat scavenging system includes a first cooling stream coupled to the exhaust system for transferring heat from the exhaust system and converting it into a first high pressure gas stream for driving a first turbine coupled to a first electric generator. The system further includes a second cooling stream coupled to the water cooling system for converting heat from the water cooling system into a second high pressure gas stream for driving a second turbine coupled to a second electric generator. The first and second electric generators effectively convert the waste heat from the internal combustion engine into electrical energy.
