1. Sea Level Compensation System for Wave Energy Converters
Abstract : The wave energy converter developed at Uppsala University consists of a linear generator at the seabed driven by the motion of a buoy on the water surface. The energy absorbed by the generator is negatively affected by variations of the mean sea level caused by tides, changes in barometric pressure, strong winds, and storm surges. READ MORE

3. System Perspectives on Hydro-Kinetic Energy Conversion
Abstract : 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.

4. Power System Damping - Structural Aspects of Controlling Active Power
Abstract : Environmental and economical aspects make it difficult to build new power lines and to reinforce existing ones. The continued growth in demand for electric power must therefore to a great extent be met by increased loading of available lines. READ MORE

5. The Nuclear Waters of the Soviet Union : Hydro-Engineering and Technocratic Culture in the Nuclear Industry
Abstract : After the development of nuclear weapons, civil applications were seen as a way through which protagonists of Soviet modernity could embrace a new future, which Josephson called atomic-powered communism. Where hydro-powered communism had reached its boundaries, nuclear energy was to take over. READ MORE
