Globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to the paucity of fuel in future. Also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. Thus the worldwide fast depletion of conventional energy resources and impact of emissions on environment necessitates the search of alternative non-conventional energy sources, and other direct energy conversion systems. This paper deals with the study of sustainable renewable energy resources and their conversion system. Air has been considered as a sustainable renewable energy resource and an emission free compressed air driven engine has been analyzed for better and sustainable energy future in this paper. Here parametric study of a vane type novel air turbine is carried out for arriving at optimal turbine specifications and operating conditions. The optimum power output obtained ranges from: 1.0 kW, 4.0 kW and 9.0 kW at D= 50 mm, 100 mm and 150 mm respectively, when rotor/ casing ratio (d/D) = 0.70, vane angle (?) is kept 30o to 45o (vanes =12 to 8 nos.), and other parameters such as: injection angle (60o), injection pressure (6 bar) and speed of rotation (2500rpm) are kept constant throughout the study.
