In this webinar Raghhild Dahl Wikstr?m from Depatment of Sociology and Human Geography and Monika Amundsen from Centre for Material Science and Nanotechnology will present their research proejects.
Title of Ragnhilds?s talk: "Everyday decarbonisation of mobility systems in suburban
centres"
Transport is responsible for a quarter of energy-related CO2 emissions. As a response, Norway has formulated a national zero-growth objective that dictates that all passenger transport growth in urban regions is to be absorbed by mass transit, cycling, and walking. The Greater Oslo Region has devised a regional transport plan, and local authorities have developed policies and initiated mobility interventions to align with the national goals. Ragnhild Dahl Wikstr?m hypothesis is that some of these policies and interventions may be disconnected from the lifeworlds and practices of citizens, and hamper the implementation of sustainability policies and plans. In this talk, Raghnhild will discuss how she explores this hypothesis by studying people’s daily mobility and different triggers of change in a selection of urban centres surrounding Oslo.
Title of Monika?s talk: "Can “magical” materials that changes their shape contribute tosolving the climate crisis by converting waste heat into electricity?"
Did you know that as much as 2/3 of the energy we use is lost as heat? The car engine, the outside of your fridge and even your computer gets hot when in use. Imagine if we could harvest some of that wasted heat and convert it back into useful energy. That would increase the overall efficiencies of many processes and could be used to exploit various sources of heat into more sustainable energy. This would contribute to solving the current climate challenge.
This can be done by using the very interesting and somewhat “magical” shape memory materials, materials that change their shape when heated and cooled. If the same materials at the same time also change their magnetic properties thermal energy can be converted in to electricity by use of a coil. In this presentation, Monika Amundsen will show some of these materials, how they work and what they can do.
