The Conversion Efficiency of Different Kinds of Energy into Electrical Energy and the Possibility of its Accumulation
Ostruška, Jan ; Bartošík, Tomáš (referee) ; Macháček, Jan (advisor)
The thesis deals with the issues of the conversion efficiency of different kinds of energy into electric energy. Firstly, the thesis presents a brief introduction into types of energy sources and their capacity. Then, conversion efficiency of particular direct and indirect conversion is scrutinized, pointing to factors which affect conversion efficiency. The next chapter deals with the possibilities of accumulating electric energy. These are analysed as far as conversion efficiency is concerned as well and the end of the chapter concludes with comparison of these particular possibilities. Booth parts of the process – power generation and its accumulation – are connected in comprehensive scheme of energy conversions. The thesis develops on this scheme by mathematic description of its components and by designing a simulation programme, which would show the flow of energy in the scheme.
New approaches to the use of energy of water waves
Novotný, Vojtěch ; Varmuža, Jan (referee) ; Radil, Lukáš (advisor)
Bachelor´s thesis deals with topic of utilization the energy of sea waves. Mainly describes existing devices transforming this energy into electricity, their division and on what principle they work. Thesis also contains description of sea waves. In the next part, the author designs and describes his own devices converting sea wave energy into electricity. If there is a similar device that is patented and exists author process a patent search to find out.

Establishment, operation and further perspective of the hydro-electric plant Lipno
HOMMER, Jan
The thesis contains essential information on the methods and possibilities of using water power. The first part deals with the history of water works, and introduction to basic physics of energy conversion. Further research is made available sources of information on the history, technology, power generation and design of hydropower Lipno I and II, with mention of unrealized project pumping plant Lipno III. The conclusion evaluates the defined objectives and creates a short summary.
Termoakustika
Trávníček, Zdeněk
The thermoacoustic energy conversion systems can operate as heat pumps (or refrigerators which are based on the same principle) or prime movers. The design optimization of the thermoacoustic refrigerator was made using two methods, namely the optimization based on the cooling load maximization and on the coefficient of performance (COP) maximization. The highest COP can be achieved with the noble gas mixture helium-xenon (62%-38%) as the working fluid, while the highest cooling load can be achieved with pure helium.
