Publication number: 20160237980Abstract: The invention relates to extracting kinetic energy from surface waves. Therein, at least one float (8) is kept floating in the area of the surface waves, while a working fluid is held in a reservoir structure (2, 3). The float is connected to a fluid displacement structure in such manner that an individual surface wave, which causes an upward stroke of the float, moves the working fluid within the reservoir structure in such manner that the potential energy of the working fluid is increased. Before the wave has reached the float, the wave is detected by a sensor (7). Based on said detection, a prediction is calculated of the amount of kinetic energy available in the wave. Tuned to said prediction, an energy transmission structure of the fluid displacement structure is adjusted for realizing the energy conversion.Type: ApplicationFiled: October 10, 2013Publication date: August 18, 2016Applicant: RIJKSUNIVERSITEIT GRONINGENInventor: WOUTER ADRIANUS PRINS

Publication number: 20160237982Abstract: A water turbine drive system is described for generating rotational power from a flowing water stream. The water turbine drive system comprises a rotating machine driven by a water turbine disposed remote from the machine, where the machine and turbine are connected together by a tether member adapted to be rotated by the turbine and transmit the rotation and thereby drive the machine. The tether member permits positional movement of the turbine relative to the machine such that the rotational axis of the turbine need not be co-aligned with the rotational axis of a driven rotating member of the machine.Type: ApplicationFiled: September 4, 2014Publication date: August 18, 2016Inventors: Joris BENNINGA, Matthew ROSS, Jayden HARMAN
