The most important features in a nutshell

The power plant concept aims at producing energy out of tides which represent a never - failing energy source. In addition, the energy production can be achieved at competitive prices without subsidies. Thus, this specific venture is not only technically appealing; it also offers a great economic potential on a market which still needs to be explored.
The production costs lie far below those of other comparable underwater power plants.
The plant can be built out of tested, prefabricated parts made of steel used for shipbuilding.
The unique, patented folding mechanism facilitates the exploitation of the incoming and outgoing tide without complicated switching procedures.
The comparably simple construction secures a virtually maintenance- free plant at a life of about 20 years.
The plant can be installed that deep under water that it is neither an impediment to shipping nor a disturbance for the spectator.
The transport from the shipyard to the construction site only requires a cargo-vessel. The plant can be lowered to the sea-bed between two pontoons with the help of construction cranes.
By holding the plant in place on two points, it is possible to fasten it, for example, to two opposing rock faces in narrow fjords in a stable and permanent way. This is possible with the help of piles being installed into the sea-bed as well as steel ropes (see animation). No extensive efforts of laying foundations are required.
In order to maintain a plant which has been braced between two opposing rock faces, the following method can be used: the bracing will be released on one side of the rock face and with the help of an additional lifting power, the plant can be brought to the surface. To remove a plant from a specific location, the steel ropes can simply be cut.
Some remarks on the environmental impact and wildlife in particular: the tidal power plant moves with the sea current. It produces energy out of the resistance it puts up to the current. This means that it moves at a lower speed than the sea current. The plant completes up to five revolutions per minute at most. Thus, all marine creatures living in the surrounding area can easily swim round or through the plant.
