Abstract: A plant that includes free-floating wave energy aggregates units for converting wave energy to another energy form. A plurality of smaller single units of wave energy aggregates is placed in a flexible grid construction. The plurality of smaller single units is connected to the grid construction in a manner so that it is fixed in a horizontal direction but flexible and capable of independent movement in a vertical direction. Advantageously, the plurality of smaller single units of the aggregate unit is placed in two staggered parallel rows arranged to take up a minimum amount of space without the plurality of smaller single units hitting each other.

Abstract: Floating slag moored wave energy aggregates at sea has to be placed in a certain distance from each other not to bump into each other. At deeper depths the security distance has to be larger. This means that the cable and other costs increases without more output of energy. At sea the energy in calculated by the meter of wave front. So the advantage is to take up a little space as possible to achieve economics. If a wave energy aggregate is built with a double width to achieve the double amount of energy, this will accomplice, that the material use will be six times more than the weight for two single aggregates. To resist the strength of forces there are on this double width the use of materials is in the third power 2×2×2=8. This means an extra expense. On the power changing machines, there has to transform the energy there is nothing to save. They still have to extract the amount of energy form a double width. Therefore, it is the challenge to achieve the same energy consumption in a cheaper way.

Abstract: A plant for utilizing the energy in the waves which are present at a given time in a section of a water area, such as an ocean or a lake. The plant comprises a base located in this section and in the shape of a platform or raft and a wave converter placed on the base and serving for transforming the wave motion of the water into whirling motion. The plant furthermore comprises a number of adjacent wave catches each having at least one catch plate for catching at least part of the water of the waves and making this water flow down along the catch plate from a top front edge to a bottom rear edge on the plate, and a whirl pipe for each wave catch for, via a slot extending along the rear edge of the at least one catch plate, taking up the water flowing along the catch plate so that this water will describe a whirling motion in the whirl pipe. The plant can utilize the average energy in the waves better and with less construction costs than known so far.

Abstract: A method for impelling water in e.g. a lake by with a pump transforming the waves of the lake into whirling water which is sent down towards the bottom of the water area. The pump comprises a horizontally extending whirl pipe with a longitudinal slot and at least one preferably curvedly extending baffle with a top front edge mainly facing a wave front in the lake in operation and a bottom rear edge extending along the slot. Both ends of the whirl pipe are fluid-connected to a submersible pipe extending down towards the bottom of the water area. The pump is simple and reliable as it functions without movable parts. The pump can without costs for external energy take surface water high in oxygen and atmospheric air down to enrich “dead” bottom water low in oxygen. At the same time the pump can advantageously be used for removing undesired constituents such as superfluous biomass from the lake and add desired additives such as lime to this.

Abstract: A plant for recovering energy from waves in motion comprises a wedge-shaped unit, anchored, and self-adjusting towards the waves. The floating reception unit (1) is placed in the water and has a ramp (3) for the waves and a guide device (4) guiding the water to a reception pipe (8) and into an energy converting engine (9). The guide device comprises a number of reception funnels (4), the cross sections of which are narrowed down in the direction towards the energy converting engine (9). The plant also comprises a number of air chambers (16) and side chambers (10) in which the reception pipes (8) end.
