Increasing the cost of fuels, growing concern of global warming and increasing demand of electrical energy, a compact, less polluting and efficient gas turbine power plant with regenerator and a suitable Waste Heat Recovery Steam Generator (WHRSG) presents a very attractive concept. Developments in metallurgical sciences, protective coatings and cooling methods have provided the options to design the components and a higher Turbine Inlet Temperature (TIT) may be achievable in near future.

Thumba (Citrullus colocyntis) seed oil can be used for production of biodiesel. A comparative experimental study, carried out on a four cylinder, direct injection, water cooled diesel engine operating on diesel and biodiesel blends (B10, B20 and B30) of C. colocyntis and Jatropha curcas, showed that like J. curcas, biodiesel of C.
