NOVELTY - The apparatus has hybrid powered subsystem that comprises wind-powered subsystem and solar-powered subsystem. The stacked thermo-mechanical engines with exchangeable thermo-mechanical engine/reversed thermo-mechanical engines mode are coupled to wind-powered subsystem for selectively converting mechanical energy into energy for controlling temperature in space or coupled to solar collector for converting generated thermal energy into mechanical energy. An interconnection subsystem is configured for coupling shafts into pairs in disengaging manner.    USE - Apparatus for converting solar and wind energy for powering electrical generator and thermo-mechanical engine e.g. stirling engine (claimed), mounted on commercial office building rooftop, parking lot and house rooftop or backyard electricity generating application.    ADVANTAGE - The simple structured hybrid solar and wind energy converter is provided with the convertible solar collector/wind deflector, so that the solar collector can be swung downward and converted into a wind deflector to increase wind-catching area and to enhance wind energy generation of the hybrid solar and wind energy converter, even in the absence of enough sun. The wind energy can be continuously harvested regardless of the weather conditions. Since the hybrid system is configured to utilize both solar and wind sources, the fluctuation in the combined energy output can be reduced and more on-site electricity can be produced in the daytime for urban and suburban areas when electricity demand is usually higher and more wind power can be produced in the nighttime and overcast days when there is essentially no solar energy available. The system can be purely operated as a wind turbine with extra wind catching area when there is no solar radiation available such as during nighttime, rainy or cloudy days, so that the solar collector is converted into wind deflector to direct extra wind flow onto wind turbine rotors. Thus the wind speed and force can be increased. The solar collectors are made of high strength, durable, non-corrosive, shock absorbent, vibration dampening and lightweight advanced composite structures. The hybrid system can be able to achieve and maintain high operational efficiencies with lightweight and reduced manufacturing and maintenance cost.
