The limitations and problems of the rechargeable battery and short mileage per one electric charging have not been overcome at the electric vehicles. To solve these problems, the hybrid vehicle has been developed by securing the performance of automotive with the conventional internal combustion engine and the environmental benefit. Meanwhile, the electric UTV (utility terrain vehicle) which has this environmental benefit has been widely used for factories, parks, leisure and agricultural areas. In this study, the electric UTV was fabricated and attached the auxiliary power drive systems including the photovoltaic power generation system into this electric vehicle in order to make up the hybrid (motor + photovoltaic) vehicle system. As the range of the hybrid UTV would be extended over 20% than that of the existing golf cart per one electric charging through this successful development, the dynamic stiffness was improved through light-weight body design.

This paper was conducted experimental work to energy recovery and syngas production using a pilot scale fixed bed gasification process of solid waste. The temperature of gasifier bottom section was the highest at about 522 ~ 808oC. The syngas composition was contained CO 10.0 ~ 11.4%, H2 8.4 ~ 11.3%, CH4 3.7 ~ 3.9%, CnHm 3.3 ~ 4.3% with lower heating value 1,500 kcal/Nm3. About 68.8% of the waste and the air energy is converted to syngas. Approximately 8.4% is lost in heat of heat exchanger and cleaning process and about 0.8% of the heat energy is recycled into the gasifier in the form of preheated air. The electric power output rate was found to range 10.5 to 12.5 kW.
