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.

A speed control system and a power load balance detector for a turbine is provided. The speed control system includes a speed wheel with a plurality of teeth. A timer stores a time stamp when each of the teeth passes by a speed probe. A first speed estimate is determined for overspeed protection, and a second speed estimate is determined for operational speed control. The power load balance detector trips or shuts down the turbine when an unbalance is above a first threshold and the speed of the turbine is above a second threshold.
