Analysis of the economic efficiency of a solar system
Mikl, Antonín ; Pithart, Jan (referee) ; Macháček, Jan (advisor)
The Master’s thesis deals with the processing of solar thermal systems for heating hot water, outdoor swimming pool and heating selected house. Introduces us how we can use the sun for the production of thermal energy through solar collectors. Furthermore, the basic components of the solar system and the types of collectors used. After this summary on the present state be the calculation of the system and fixing the price of the investment. The economic part of the evaluate if this system to invest, eventually appoint a return on investment.

Thermo-electric solar generator
Kočvárek, Ondřej ; Jakubová, Ivana (referee) ; Gregor, Jan (advisor)
The introduction of this work is devoted to the description of physical principals and condtruction of modern semiconductor thermoelectric transformers. This work describes thein basic characters and the most commonly used materials for thein production. Further, it mentions the basic principals and physical effects that describe the thermoelectric conversion of energy and the nondestructive method for establishing the basic material characteristics of thermoelectric transformers. The substantiv part of this work is the measuring of the material’s characteristics of the accessible thermoelectric elements through the medium of experimental measuring network. The optimal construction of thermoelectric solar generators used for individual thermoelectric elements are designed based on the taken measurements and the evaluation of material’s characteristics of the observed thermoelectric elements.

Operational efficiency of photovoltaic generators
Koval, Filip ; Václav, Březina (referee) ; Gregor, Jan (advisor)
Objective of master’s thesis theoretical part is especially to illustrate influence of operation conditions, such as solar radiation, temperature or pollution of photovoltaic generator active area, on load and power characteristics of photovoltaic generator, or more precisely on photovoltaic conversion efficiency. Possible variants of increasing effectivity of using photovoltaic generator are explored, such as solar radiation concentration, photovoltaic generator active area cooling or aplication of optimalization circuit. Pivotal part of master‘s thesis is focused on experimental device practical realisation, concretely type MSQ36-10 photovoltaic generator with oriented concentrators of solar radiation. Practical realisation includes design of master‘s thesis experimental part construction with subsequent design of photovoltaic generator motion cycle necessary for adequate simulation of configuration variants solved using single testing photovoltaic generator. Description of own experimental device construction with list of measuring places used in task takes up. It is used automatic monitoring system working as independent measurement task for required values measuring and consecutive data collecting. It is done in two phases. First phase is measurement of all required values, in second phase measurement with attached optimalization circuit is made. Optimalization circuit sets best working point of photovoltaic generator according to actual working conditions. Master‘s thesis intention is experimental verification of solar radiation concentrators application convenience, orientation of photovoltaic generator or its mutual combination, namely using type MSQ36-10 photovoltaic generator. Objective is evaluation of reached energetic gain for all experimental device layouts in variable operating conditions.

Science & Technology Park in Zlín
Kožíšek, Vladimír ; Svoboda, Jiří (referee) ; Zemánková, Helena (advisor)
The subject of this thesis is the project of scientific and technological park in the Tomas Bata University in Zlín. This park is divided into three workplaces: the educational and training center, a workplace for applied research, and business center. This project is situated at the location of a former factory area of Baťa Company; specifically in its eastern part. This dissertation is focused on the analysis of the given location, evaluates it in terms of its potential, and finally sets out the main priorities that should be applied in the draft. The accompanying report then describes and specifies the project, as drawn graphically, in the form of situational patterns, plans, sections, perspectives, and visualizations. Specifically, the project deals with the reconstruction of the former manufacture building No. 24, proposes a construction of a new building no. 25, and provides a solution for space in between of these two buildings. The project primarily seeks to make the entire site more attractive, and bring it to the function which would implement the functions in the assignment of the technology park. The function of the technology park is divided with regard to the investors requirements. From the urban point of view, the project seeks to approach the problem stemming out of the essence of the place. The use of objects remaining on the site preserved, is designed not to disturb the architectural expression and static essence. Architectural expression of new objects is selected not to oppose the overall architectural expression of the site. The project also includes and evaluates the usage of solar energy.

Hydrogen fuels
Umlauf, Martin ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
Paper presents a basic review and comparison of energy-conservation made of renewable sources. Principal question of paper concerns evaluation of hydrogen-use made of electrolysis of water. First part of the thesis focuses on the production of energy from renewable sources and the possibility of energy-accumulation. The next section describes methods of hydrogen production and utilization of hydrogen as a fuel for combustion engines. Attention is paid to various aspects dealing with construction of combustion engines using hydrogen. Final part of the study presents comparison between combustion engines using known sorts of fuels as to their pollution and emission-level. Next comparison deals with economic cost per kilometer, when different sort of fuels are taken into account. Conclusion concerns approximate calculation of the production of hydrogen from water by electrolysis using photovoltaic power plants.
