Collecting energy from the environment and thermoelectric conversion

U radu su opisani različiti oblici prikupljanja energije iz okoline i njihova pretvorba u električnu energiju. Poseban naglasak je stavljen na termoelektričnu pretvorbu , koja se bazira na detaljnim teorijskim objašnjenjima pretvorbe te teorijski i praktički opisanim postupkom izrade projekta termoelektričnog generatora. Na modelu izrađenog generatora izvršena su mjerenja pomoću kojih dobivamo grafički prikaz rada generatora u praznom hodu i pod opterećenjam. Usporedbom dobivenih rezultata mjerenem i rezultata dobivenih numeričkim proračunom dobijemo mala odstupanja koja nastaju uslijed pogreške instrumenata te zbog ne mogućnosti mjerenja svih parametara istovremeno.This thesis describes the various forms of collecting energy from the environment and their conversion into electricity. Particular emphasis is placed on the thermoelectric conversion that is based on a detailed theoretical explanation about conversion, and theoretically and practically described process of a design of the thermoelectric generator. On the model of a built-up generator measurements were carried out by which a graphical representation of a generator at idle and under load was obtained. By comparing the results gained by measurement, and the results that were obtained by a numerical analysis we get small deviations that result from the errors of the instruments, and the impossibility of measuring all parameters simultaneously
