  1. 1. Horses vs. Machines: A Comparative Energy Analysis between Eighteenth Century- and Modern Copper Mining

    University essay from Lunds universitet/Humanekologi

    Author : Amos Strömberg; [2021]
    Keywords : Copper mining; embodied energy; small-scale mining; degrowth; copper ore grade; Podolinsky’s principle; large-scale mining; 18th century mining; mining; Social Sciences;

    Abstract : This study shows the positive benefits of early 18th century copper mining in terms of energy efficiency due to the utilization of animate power, pre-industrial machinery, biofuels and a small-scale of organization. Based on the concept of embodied energy, this study calculates the inputs in early 18th century Falun Coppermine in Sweden and compares it with present-day Chibuluma Coppermine in Zambia. READ MORE

  3. 2. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method
