Atlantisstrom
Between two circular plates, each eight meters in diameter, mounted on supports, is the efficiency-optimized number of five drop-profiled blades, each 20 meters long. These size specifications apply to the first prototype, which was calculated by the Pfleiderer Institute for Turbomachinery at the Technical University of Braunschweig in several study projects. The turbine owes its ability to rotate - completely under water - to a completely new, patented folding mechanism of the blades, which causes an energy surplus at the pressure surfaces of the blades on the flow side, which starts the turbine and keeps it moving. The electric current is generated by a generator attached to the side plates. Two-point mounting of the turbine makes it possible to secure it stably and permanently in fjords without major foundation work, e.g. on two opposite rock faces by means of ropes (see above). In addition, the system can be fixed in softer seabeds by means of driven-in steel tubes.
