Osvětlovací systémy v ostrovních aplikacích / Lighting systems in off-grid applicationsLengyel, Ladislav January 2015 (has links)
Aim of the master's thesis is at first to explain appropriate light sources and lighting systems; secondly present suitable light sources selection for lighting a small space and design of an off-grid system. The last part consists of an overview about alternative energy transformations to light energy. The first of these three major themes focuses on the analysis of light sources suitable for use in applications with accumulation together with data on energy efficiency and the utilization efficiency associated with them, concentrating on their consumption and possible energy saving lighting within small applications. It ends with a description and calculations of electricity energy indicators for different types of rooms. The second and main part of the thesis is focusing on suitable light sources selection for off-grid systems and impacts on humans and the environment associated with it. An object representing a small application has been created in RELUX® software with suitable light sources installed in it. For this scene, appropriate parts of off-grid systems were selected, which could be used to power the proposed lighting. The last theme consists of a brief about alternative sources, most of which are still in development or existing only at a theoretical level. All of these alternative sources are having a possible application in the future.

Konstrukční řešení modelu průtočné říční elektrárny / Hydro power station designNovák, Pavel January 2008 (has links)
This thesis deals with designing a small hydraulic power plant, where a swirl turbine is conected to a unique synchronous working, which will offer a reliable and easy installation of the hydraulic power plant. As a result a wider potential of energy could be produced from renewable resources. The use of a narrow rottor as a holder of the permanent magnets is the biggest difficulties of this design.

Zdravé bydlení / Healthy LivingZhuravlyova, Yelena Unknown Date (has links)
Over the years, every major city turns into a knot of intractable problems: overpopulation, traffic jams, environmental degradation. Some countries make a faster conversion from an industrial development to an information growth phase, than the infrastructural changes take place. Therefore, environmental design and construction would not be short-termed, but rather will be the long-term targets for all the groups associated with the construction. The healthy living is one of the most important reasons to start a complicated long-term reconstruction of eco-cities. Successful ecological reconstitution requires a knowledge about already implemented exemplary solutions. For this purpose, the dissertation analyzes the basic ecological problems of settlements, analyzing the examples of approaches to improve the environmental performance of cities on the reference of foreign experience and creates criteria and principles for designing urban structures for healthy living in CR.

Navigating Sustainability : A case study exploring alternative energy sources for maritime shipping / Navigerar hållbarhet : En fallstudie som undersöker alternativa energikällor till fraktfartygNordenskiöld, Simon January 2024 (has links)
This master thesis studies alternative energy sources for maritime shipping in Sweden. With current climate goals, and a need for change, the maritime sector currently undergoes intense transitions. For shipping companies to lower their carbon footprint, the need to replace non decarbonised fuels is hence critical. With numerous alternatives, currently being developed, actors are phasing obstacles regarding which energy source that is most mature in terms of technical readiness as well as how adequate it will fulfil current climate goals. This study will analyse four different energy sources, liquid hydrogen (LH2), electro-methanol (emethanol), electro-ammonia (e-ammonia) and wind (sails), and answer which out of these energy sources will be most suitable for actors to adapt. To answer this question, the Technological Innovation System framework has been utilised, and the results has been applied to some chosen climate target actions developed by Swedish authorities. The findings proved that e-methanol currently is most mature and has reached most alignment with current climate goals, followed by LH2/wind and lastly e-ammonia. / Detta examensarbete studerar alternativa energikällor för fraktfartyg i Sverige. Med nuvarande klimatmål, och ett behov av förändring, genomgår den maritima sektorn intensiva omställningar. För att rederier ska kunna sänka sitt koldioxidavtryck är behovet att ersätta icke koldioxidneutrala bränslen därför stort. Med ett flertal alternativ, som för närvarande är under utveckling, står aktörer inför hinder angående vilken energikälla som är mest redo gällande teknikmognadsgrad samt hur adekvat den kommer att uppfylla nuvarande klimatmål. Denna studie kommer att analysera fyra olika energikällor, flytande väte (LH2), elektro-metanol (e-metanol), elektro-ammoniak (e-ammoniak) och vind (segel), och ta reda på vilka av dessa energikällor som är mest lämpad för aktörer att använda sig av. För att svara på denna fråga har ramverket Technological Innovation Systems använts och resultaten har tillämpats på några utvalda klimatmålsåtgärder som tagits fram av svenska myndigheter. Resultaten visade att e-metanol för närvarande är mest mogen och har nått mest anpassning till nuvarande klimatmål, följt av LH2/vind och slutligen e-ammoniak.
