    Abstract: A marine propulsion unit including a rotary casing rotatable about a central axis A, and blades extending axially from the rotary casing for rotation with the rotary casing about the central axis A, wherein each blade is mounted for pivotal movement about blade axes B. A blade shaft portion of each blade is at least partly surrounded by a blade housing and by a blade portion of each blade is outside the blade housing, wherein the blade housing is releasable attached to the rotary casing, and each blade being supported in the blade housing by means of bearings for the pivotal movement.

    Abstract: A system for cooling a solar power plant is provided. The system has a foundation, a protective housing built on the foundation, and one or more heat sources inside the protective housing. An air inlet can provide a cooling air flow from outside the protective housing to inside the protective housing, and an air outlet can allow an air flow heated by the at least portion of the heat sources to exit the protective housing. An air duct system within the foundation can direct at least part of an incoming air flow to another part in the protective housing.

    Abstract: A user interface of frequency converter over a wireless connection is disclosed. The frequency converter can be connected to a mobile communications device over a short range wireless connection. The mobile communications device can be connected to a wide area network to a service center maintaining information associated with frequency converters. Operational information of the frequency converter can be relayed to the service center over the wide area network as a view of the frequency converter user interface. The frequency converter can be controlled by control commands from the mobile communications device, the control commands being determined based on selections received from the service center, in response to the view conveyed to the service center.

    Abstract: A method of optimizing one or more starting parameters of a solar power generator system and a solar power generator system, wherein the solar power generator system includes a solar panel array and a converter for converting power obtained from the panel array. The method can include measuring an output voltage of the panel array, comparing the output voltage with a starting voltage (Vdc), starting the solar power generator system when the output voltage of the panel array exceeds the starting voltage (Vdc), measuring the obtained power from the solar panel array after a morning start, comparing the obtained power with a known limit value, and changing the one or more starting parameters on the basis of the comparison of power.
