  1. 1. Fossil Capital : The Rise of Steam-Power in the British Cotton Industry, c. 1825-1848, and the Roots of Global Warming

    Författare :Andreas Malm; Humanekologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fossil economy; steam-power; water-power; cotton industry; Britain; capital accumulation; global warming;

    Sammanfattning : The more we know about the catastrophic implications of climate change, the more fossil fuels are burnt in the world. How did we get caught up in this mess? This thesis returns to a crucial moment in the emergence of the fossil economy: the rise of steam-power. LÄS MER

  3. 2. Power cycles with ammonia-water mixtures as working fluid

    Författare :Eva Thorin; KTH; []
    Nyckelord :;

    Sammanfattning : It is of great interest to improve the efficiency of powergenerating processes, i.e. to convert more of the energy in theheat source to power. This is favorable from an environmentalpoint of view and can also be an economic advantage. LÄS MER

  4. 3. Collaborative Multidisciplinary Design Optimization for Conceptual Design of Complex Products

    Författare :Edris Safavi; Johan Ölvander; Mehdi Tarkian; Hampus Gavel; Jerzy Pokojski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : MULTIDESCIPLINARY design optimization (MDO) has developed in theory andpractice during the last three decades with the aim of optimizing complexproducts as well as cutting costs and product development time. Despite thisdevelopment, the implementation of such a method in industry is still a challenge andmany complex products suffer time and cost overruns. LÄS MER

  5. 4. Cost-Effective Pathways for Gasification-Based Production of Biofuels

    Författare :Johan Ahlström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomethane; power-to-gas; Biorefinery; SNG; heat integration; bark; Gasification; sawmill; hydrogen;

    Sammanfattning : A considerable number of studies indicate that biomethane produced through gasification of lignocellulosic biomass could contribute significantly to greenhouse gas emissions reduction in the transport sector. However, the production costs are high compared to fossil-based alternatives, which has limited deployment of the technology. LÄS MER

  7. 5. Simulation model of a ship’s energy performance and transportation costs

    Författare :Fabian Tillig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; speed optimization; energy efficiency; wind-assisted propulsion.; performance prediction; energy systems model; ship design;

    Sammanfattning : Society faces a major challenge to reduce greenhouse gas emissions to limit the effects and propagation of climate change. As the main contributor to global trade, the shipping industry adds significantly to global greenhouse gas emissions and must actively work towards reducing, or eliminating, emissions in a short period.
