A method for constructing an underwater pumped-storage power plant in a dry but floodable ground depression is disclosed, wherein a plurality of pressure vessels are provided or built in the dry ground depression, wherein the plurality of pressure vessels are arranged side by side and/or one above the other in the dry ground depression, where they serve as a lower reservoir for the underwater pumped-storage power plant to be constructed, and wherein the pressure vessels are designed such that they each have at least one flow-through opening for admitting and/or discharging water and are pressure-resistant such that they can be pumped dry in a dimensionally stable manner against a hydrostatic water pressure acting on the pressure vessels from the outside when the dry ground depression is flooded with water.

Method for constructing a pumped storage power plant in a ground depression, in particular in an open-cast mine

A method for the preliminary use of a partially constructed lower reservoir for an underwater pumped-storage power plant is disclosed, wherein a partially constructed lower reservoir is provided which is located in a dry but flooded ground depression, and which, when the dry ground depression is flooded, can be operated in such a way that electrical energy is generated when water is admitted into the lower reservoir from the flooded ground depression and electrical energy is stored when water is pumped out of the lower reservoir into the flooded ground depression, wherein the partially constructed lower reservoir is connected to a preliminary upper reservoir via a penstock.

Method for provisionally using an at least partially constructed lower reservoir for an underwater pumped-storage power plant

A pumped storage power plant for a temporary reversible storage of energy, such as the energy available from wind power stations and/or photovoltaic systems that is fluctuating over time. The pumped storage power plant is designed as an underwater pumped storage power plant, wherein the ocean assumes the function of an upper storage basin and a pressure tank placed on the ocean floor serves as a lower storage basin. The storage of the electric energy takes place through pumping water out of the inside of the pressure tank against the hydrostatic water pressure on the ocean floor.

Pumped-storage power plant

A method and apparatus for image signal decoupling in position-transmitting high-vacuum electromagnetic radiation quanta or particle detectors. The electromagnetic radiation quanta or particles impinge on a spatially resolving anode structure through a photoelectron converter layer (in the case of electromagnetic radiation) and directly through an electron multiplier as an electron avalanche (in the case of particle radiation). The electron avalanche is first collected for a short time inside the vacuum on the anode side by means of a high-resistance, conducting semiconductor thin film, and is then read out capacitively from the outside through the glass bottom (counter-substrate) of the detector device as an image charge by means of a low-resistance anode layer of suitable structure. The capacitive decoupling permits high spatial resolution when the internal resistances of the charge collecting layer and the readout anode layer are optimally adapted to one another. The decoupling requires only a simple high-resistance monolayer in the vacuum with a single voltage contact. The spatially resolving anode structure outside the vacuum can be modified or exchanged to individually adapt the spatial resolution.
