Utilizing of wind energy with accumulation
Mészáros, Gabriel ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The introduction of this paper deals with wind-powerplants, their components and distribution according to their construction and output. Technologies of accumulation of energy are described, because the conditions for energy production from wind are not constant (windlessness, storms, etc.). The technologies are compared in terms of economics and technology. A basic design for a system with accumulation is made at the end of the thesis.

Alternative Energy Sources with Focus on "Solar Energy Sources in Present Practice"
PECHA, Radim
The thesis deals with the problems of alternative energy sources with focus on solar energy sources in present practice. The thesis introduction explains the reasons of the changes in the global fuel-energy balance and their adverse effects, characterizes individual alternative energy sources and their practical applicability. The main focus is on exploitation of solar energy. After explaining the principle of thermonuclear reactions as the source of energy in the Sun, the thesis analyses the question of production of photovoltaic cells and a solar module. It describes the types of commonly used accumulators, charges and voltage transformers. It points out all factors, which must be taken into account when handling solar panels in practice. In the last chapter, it in particular deals with the didactic instructions for teaching the topic of alternative energy sources at elementary schools, as well as the need for introduction of the mentioned topic to teacher colleges.

Examine selected properties of accumulators
ŠOPEJSTAL, Michal
The aim of this Bachelor thesis is examine selected properties of accumulators. In the literary part are mainly described their characteristics of charging and discharging, parameters of working life and construction. The next part is about methodology for practical verification selected properties of the accumulators. Another part consists of comparing and measurement four selected accumulators. Obtained data from measurements are then evaluated.
