The diameter of the vortex basin is 5 meters.
The head - difference between the two water levels - is 1.6 meters.
The turbine produced 50.000 kw/h in its first year of operation.
Construction cost was 57.000 Euro
Works out to about $13.48 per W capital cost.
Expensive, but without the generator it is a work of art. What a
beautiful thing. If the turbine were mounted only on underwater
structures it would still be artful. The overhead wood structure for
the generator makes it ugly. If built only for aeration then an
underwater mounted set of Venturi tubes, or a slotted cone, might be
artfully achieved, maybe along with some integrated sculpture.
That structure with turbine is easily adapted to driving an
underwater pump for water lifts for irrigation.
