| Popis: | 101 The object of this thesis was to design and prototype a Fresnel lens and a parabolic reflector, which were intended to acquire solar radiation heat and focus on a Sterling engine’s hot spot. Hence, the thermal energy revenues were converted into the engine’s mechanical movements, and then deformed a plural of piezoelectric bimorphs to generate electric power, which was utilized to charge small electric energy storage elements for succeeding load applications. This study employed an optical ray trace analysis tool TracePro to design the Fresnel lens and the parabolic reflector characteristics, and the object of the design simulations was to obtain an optimal solar power focusing at preferred locations with affordable or achievable lens or reflector geometry and material options. The designed Fresnel lens and parabolic reflector were prototyped and integrated with the Sterling engine and the piezoelectric generator module, and the acquired solar energy successfully supplied thermal heat to the engine to extend the rotation durations of the piezoelectric module center axle, which in turn deformed the bimorphs to deliver electric power to its succeeding loads. Therefore, the experiments verified the feasibility of acquiring solar radiation energy using the Fresnel lens and parabolic reflector designed in this thesis. |
