Abstract:The aim of this bachelor´s thesis is to refer briefly about possibilities of obtaining energy from locally available resources for autonomous object and the definition of the term –
an autonomous object. This bachelor´s thesis mentions processes how to gain energy from different sources, possibilities of their implementation (from a legislative perspective) or suggestions on how to save gained energy. We are concerned in the autonomous objects primarily and in the acquisition of heat and electrical energy, so the thesis is also divided into two main subsections dedicated to determining the required amount of the energy that would cover our demand for it. The next section briefly discusses the construction of Savonius wind turbine generator which we can build ourselves. This is a hybrid system that consists of a solar photovoltaic panel and the wind turbine with the appropriate electrical devices. Construction of Savonius wind turbine is documented in the chapter Appendix, where you can find photographs showing construction phases. It should be noted that the construction is not completed and the determination of some parameters were not possible technically at home. These measurements would be flawed. Individual issues are then briefly explained and described how they would be in the ideal case. In conclusion, the procedure for calculating is outlined by the method called NPV (Net Present Value), which is often used.

Process of defence
Student prezentoval svoji bakalářskou práci a postupně odpověděl na všechny na všechny otázky uvedené v oponentním posudku. Komise byla s odpověďmi spokojena. Dr. Macháček se zeptal: „Dělal jste nějaký průzkum trhu Savonivých rotorů?“ Student odpověděl, že se o tuto tématiku zajímal avšak aktuální nabídce se neorientuje. Ing. Jiří Holoubek se zeptal na doplňující dotaz: „Máte představu o energetické náročnosti objektu?“ Student konkrétní čísla nevěděl ani hrubým odhadem. Dále nedokázal reagovat na výhrady Dr. Macháčka týkající se odchýlení práce od zadání.
