Förnybar energi på SvalbardAndreasson, Tobias, Lindh, Emelia January 2018 (has links)
This degree thesis investigates the possibilities of producing food inside a container at Svalbard, using renewable energy and energy storage. The idea was to be able to place the container at remote places without the need of being connected to the grid. We chose Svalbard, where it is cold and the sun is shining 24 hours a day at summertime. In the winter the opposite occurs and the sun is absent from the sky. The work is divided into theoretical studies and results based on different calculations. Such as economical evaluations (LCOE), and simulations using the computer programs Matlab and PVsyst. We have investigated if solar power and wind power is suitable as energy sources. Options for storage were batteries, grid and hydrogen storage. Different cases with Photovoltaics- and wind power plants, with batteries or grid, were compared against each other. It is not possible to use the grid as storage. This resulted in different sizing of our cases, with no excess energy production. The result showed that a 5 kWp photvoltaic plant with dual axis tracking system, was the most profitable. The Pay off would be 14 years and the total profit 63 453 SEK. If it will become possible in the future to use the grid at Svalbard as storage, it will open up opportunites for bigger systems. This will lead to higher profit than with smaller ones. Our results show that it is now most profitable with solar power.

Midnattssol : Metamorfoser och medvetandefilosofi i The Hidden Oracle och Midnight Sun / Polar Night : Metamorphoses and Philosophy of Mind in The Hidden Oracle and Midnight SunJonsson Höök, Malin January 2021 (has links)
The aim of this work is to examine how physical and mental metamorphoses affect the perception of the self. To do this I study the literary characters Apollo (The Hidden Oracle, by Rick Riordan) and Edward Cullen (Midnight Sun, by Stephenie Meyer), both of whom experience these different kinds of metamorphoses. I approach this problem with the help of philosophy of mind and, more specifically, the mind-body problem as well as the problem of personal identity. Amongst other things, I find that the physical metamorphoses are what enable and initiate the mental ones. I also discover that one of the biggest impacts on personal identity and the self comes from whether the characters are immortal or not.
