A useful approach for energy savings involves combined heat and power production (cogeneration). These technologies are discussed.

A turbine plant, using solar energy as a heat source, has been studied. The facility is used as a pump drive or electric-power generator. It is suitable for use in waterless areas, is easy to operate and maintain, and has high thermal efficiency. A computer-aided optimization was carried out for...

The thermoeconomic analysis of a gas turbine engine with two turbines is presented and discussed in this work. Two configurations (in parallel and series free turbine) are presented and analysed. The thermoeconomic analysis relies on the energy and exergy analysis of the system, and the capital...

The direct-injection stratified charge (DISC) engine is a hybrid between spark ignition (SI) and compression-ignition engines, it combines many of the best features of both with some unique advantages of its own. This includes multi-fuel capability, high thermal efficiency, low NOx production,...
