The grid construction make it possible, to achieve lower weight because of the units get smaller but strong enough to resist the forces of the sea on the smaller size (wave front).
A smaller size do that one to achieve the same amount of kW has to use more units. This leads to a bigger production (mass production) that makes it cheaper to achieve the same kW out o the waves.
One will save about 70-75 % material in the single wave energy aggregates of half size.
The invention is in the first place thought to be uses for specific wave energy aggregate (claim 10), but can also be used to nearly any other floating wave energy aggregates.
In the calculations to find the necessary distance between wave energy aggregates at sea, it was clear, that a wave energy park to up a lot of space-to much space. The floating wave energy devices must not be able to hit into each other, when there is no waves and no wind.
To be close to each other, without hitting each other, they have to be fixed with something, there in the same time is flexible. The power of the sea is so enormous, that it is better to bend for the forces than to try to resist them. The construction price is also much cheaper.
The normally trend in wave energy aggregates is built on the principle from wind energy industry: get as many MW on fewest items. A given width of wave front is containing a certain amount of energy. The double width is containing the double as much energy. So - built double as big.
To construct double width wave energy aggregate in a traditional way, there is able to resist the very big forces, it takes material in at least third potent, 2 x 2 x 2 = 8 times. The wave energy aggregate is not only double as width, but also double as high and double as deep in the bearing dimensions of material. But one only achieves the double energy of energy.
Actually there are used 6 times more material to exchange the two single wave energy aggregates to a new double width wave energy aggregate.
The grid construction is a flexible grid ; there is fulfilling the demands for a park of wave energy aggregates to take up less space without the aggregates can hit each other.
The grid constructions consist of sticks, there are holding the aggregates fixed in horizontals direction, but flexible in vertical direction. When this achievement is reached, then you as well can go a step further-make the things smaller (to a limit fitted to the conditions) and by this achieve price-and weight reduction with all its advantage.
With the new flex grid constriction is then much cheaper. It can be adjusted in series and sizes to any sea area and to the demand of MW there is wished for.
