Abstract
Research of an energy system corresponding to ZEH (Zero Energy House) is advanced so as to aim at reduction of the energy consumed in domestic use. The authors are developing a hybrid heat source Stirling engine CHP (combined heat and power) system, which uses solar and woody biomass for a heat source and supplies power generation and warm water. This paper describes a development of a 200W Stirling engine generator driven by solar energy using a solar collector made by a Fresnel lens. It has an α (2-piston) type structure operated by a Scotch yoke mechanism and now is made experimentally.
