6. Direct Ground Cooling Systems for Office Buildings
Sammanfattning : The solving of crucial global energy challenges hinges on improving energy efficiency in building energy systems. Accomplishing energy-efficiency targets often entails incorporating sustainable energy sources into the energy supply system. LÄS MER
7. Direct Drive Generator for Renewable Power Conversion from Water Currents
Sammanfattning : In this thesis permanent magnet direct drive generator for power conversion from water currents is studied. Water currents as a power source involves a number of constrains as well as possibilities, especially when direct drive and permanent magnets are considered. LÄS MER
8. Unveiling the nature of dark matter with direct detection experiments
Sammanfattning : The desire of discovery is an anthropic need which characterises and connects the human being over the eras. In particular, observing the sky is an instinctive drive exerted by the curiosity of the mysteries which it retains. LÄS MER
9. Extreme Load Conditions for Wind Powered Direct Drive PM Generators
Sammanfattning : Wind energy is a rapidly growing energy source with vast potential. Vertical axis wind turbines could be more cost-effective than the three bladed horizontal axis turbines that dominate today. LÄS MER
10. System Perspectives on Hydro-Kinetic Energy Conversion
Sammanfattning : Free-flowing water currents such as tides and unregulated water courses could contribute to world electricity production given the emergence of robust technical solutions for extracting the energy. At Uppsala University, a concept for converting the energy in water currents to electricity using a vertical axis turbine with fixed blade-pitch and a direct-drive permanent magnet generator is studied.
