Seawater desalination
Kamenický, Robin ; Hájek, Zdeněk (referee) ; Maar, Tomáš (advisor)
Každodenní nedostatek pitné vody vede ke snahám tento problém řešit. Jedna z možnosti je odsolování ať už destilační, za pomoci membrán a osmózy, či dalších nekonvenčních způsobů jako je zmražení vody. Tato práce se zabývá možnostmi odsolování. Popisuje způsoby destilační, reverzní osmózu, solární odsolování a nezapomíná ani na separaci pitné vody pomoci zmražení. Spolu se získáváním pitné vody ze slané nastává také otázka energetických zdrojů. Využití fosilních paliv, obnovitelných zdrojů energie a jaderné energie, je tedy další nepostradatelné téma popisované v této práci. V neposlední řadě se zde také můžete dočíst o možném dopadu odsolování na životní prostředí, ať už z hlediska globálního v podobě možné produkce skleníkových plynů nebo dopadů lokálních. V závěrečné kapitole je podrobná ekonomická analýza odsolovacího zařízení pomoci počítačového programu DEEP. Popisované zařízení je na bázi multi effect distillation a reverzní osmózy, pro které se získává energie z jaderné elektrárny.

Future energy sources
Hatiar, Peter ; Moskalík, Jiří (referee) ; Škvařil, Jan (advisor)
This work deals with the issue of energy resources. It deals with the energy challenges for the coming decade, it briefly describes the various energy resources and assesses their potential. Given the scale of that issue, the work is focused on the use of energy resources, especially for electricity production.

Measurement of the properties of solid and liquid fuels (biofuels)
Horák, Jakub ; Štelcl, Otakar (referee) ; Moskalík, Jiří (advisor)
Nowadays there are large numbers of standard methods for measuring the properties of fuels. With the increasing number of new methods to an already confusing issue of measurement of fuel becomes even more confusing. This thesis therefore deals with the measurement of the energy properties of solid and liquid fuels (biofuels). The introduction is carried out searches of solid and liquid fuels (biofuels). Search is focused on the description of each type of fuel, their properties and adjustments to the final form suitable for combustion. The next part deals with the sampling of fuel, which divides the sampling and preparation of samples for laboratory testing. The last section describes the methods of measurement of selected energy fuel properties and selects appropriate methods. Methods of measurement of selected properties is then checked in the laboratory.

Possibilities of Heating of Family House
Řezníček, Jan ; Štelcl, Otakar (referee) ; Lisý, Martin (advisor)
With the growing interest in cost saving and environmental protection we are trying to take advantage of new trends in building insulation and heating. The aim of this bachelor thesis is to present the issues and options for heating these buildings using new technologies and methods, to describe the design of individual boilers, their properties and uses depending on the type of fuel, and to assess the economic performance of selected heating options for a particular building.

Combustion of Solid Fuel in Unsuitable Boilers
Ondrůj, Jakub ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
The aim of this work is to investigate the combustion of various solid fuels and experimentally verify the environmental impacts of combustion of selected solid fuels in inappropriate boilers. The first part of the thesis is focused on the determination of solid fuel burning conditions and the second part describes the basic combustion tests, the comparison of the measured emissions during combustion of selected fuels and the comparison of these results with the valid emission limits.

Methods of CO2 separation from air, ways of its use and long-term storage
Kober, Ondřej ; Baláš, Marek (referee) ; Škorpík, Jiří (advisor)
Combustion of fossil fuels creates greenhouse gas emissions that cause global warming. The most important of these gases is carbon dioxide. Although it occurs naturally in the atmosphere, human emissions upset the balance of various natural processes. The aim of this bachelor’s thesis is to conduct a background research in the field of carbon dioxide capture, storage and utilization. The thesis also describes the role of carbon dioxide in the atmosphere, its cycle and human influence on carbon dioxide concentration.

"Too cool to pretend to care"
Vinklárková, Tereza ; Remešová, Anna (referee) ; Sterec, Pavel (advisor)
The aim of the project is to capture the consumer attitude of society, the millennial culture, fake news, as well as planetary and social changes. It presents a stylized post-ironic statement of mostly narcissistic millennials, whose social platforms have become the main platform for expression, forcing us to reflect on the variety of information we are surrounded by and the need of its selection. It also opens the discussion about the phenomenon of denying the existence of climate change visible through the absurd arguments and the phenomenon of geoengineering, targeted human interventions in natural processes, primarily to permanently or at least temporarily cool the planet.

Power sources in the Czech republic concentrated on using biomass
Vacek, Tomáš ; Liedermann, Pavel (referee) ; Špaček, Jaroslav (advisor)
This article introduces independent sources of electric energy in the Czech Republic, the different types of power plants, their productivity and the quantity of electric energy delivered to the main distributor. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.

Separation and storage of CO2
Odložilík, Martin ; Chroboczek, Libor (referee) ; Pospíšil, Jiří (advisor)
The main objective of this work is to clarify the methods for CO2 capture and storage as an option to limit global warming. The first part is further explained by a phenomenon known as the greenhouse effect, there is illustrated his principle, the effects of climate change, the main factors increasing its intensity and its possible reduction. Framework of the second part is description of the technologies and methods of CO2 capture and storage, the individual steps in these processes and also the possible development in the future. Next chapter discusses the pilot research programs and application of referred technologies to in practice. The last part of this work is devoted to the economical aspect of the problems.
