Definitions

  • the present invention generally refers to an apparatus and plant for the production of renewable energy.
  • the present invention relates to an apparatus and a plant for the production of renewable energy starting from the hydraulic energy deriving from a water flow rate of a free surface channel, for example an irrigation channel, or even a water course with large flow rates, in consideration of the fact that it can work completely submerged.
  • Apparatuses and plants are also known for the production of renewable energy starting from the water flow rate of a free-surface canal which withdraw a water flow rate from the canal through pipes and hydraulic works and introduce it into a turbine, to then return it to the channel.
