An installation for storing thermal energy which can be obtained, for example, at times of overcapacities, from regenerative energy and then be stored is provided. The energy stored in a heat accumulator, a cold accumulator and in an additional heat accumulator can be, when needed, reconverted into electrical energy by circuits via a generator (G) while using a compressor and a turbine. The working gas is humidified by a humidification column, ideally until saturation, whereby, advantageously, a greater mass flow can be obtained at a lower volume flow. For this reason, more economical components can be used while simultaneously a high yield of the installation is achieved.

A wind turbine for power generation is provided. The wind turbine includes a power generating unit and a rotor having a plurality of blades. To control power output of the wind turbine, the blades are capable of being pitched by a blade pitch adjusting device. The wind turbine also includes a pitch control unit for controlling the blade pitch adjusting device. Furthermore, the wind turbine includes a load determining device for determining the blade load from the pitch activity of the blades.

A cutting machine for producing lamina elements includes a cutting mechanism for cutting out a first lamina element from a foil at a first position within the foil and for cutting out a second lamina element from the foil at a second position within the foil. With respect to a centerline of the foil the first position has a first distance and the second position has a second distance being different to the first distance. The cutting machine is adapted for releasing the cut out first lamina element and the cut out second lamina element, such that by utilizing the gravitational force the first lamina element and the second lamina element are transferred to a container, in which they are arranged in a stacked and in an aligned manner with respect to each other.

An offshore support structure is provided, including at least one upper support structure section for supporting at least one functional device with a functional mass, at least one lower support structure section for founding the offshore support structure at a seabed of a sea and at least one transition support structure section which is arranged between the upper support structure section and the lower support structure section for physically connecting the upper support structures section and the lower support structure section. The lower support structure section forms a foundation of an offshore tower installation. With such an arrangement, it is possible that the transition support structure section is developed with a lower mass in comparison to an arrangement where the transition support structure section is in the water. The offshore tower installation is used for offshore wind power plants.
