Bidirectional system and apparatus for generating power

A system for use in generating electricity from a bidirectional water flow, comprising:

• an apparatus including:
• a base structure;
• a primary flow pipe defining a first flow passage through the base structure;
• and
• a secondary flow pipe defining a second flow passage through the base structure, wherein the first and second flow passages are configured for bidirectional flow;
• the primary flow pipe comprising:
• a convergent section;
• a mixing chamber, the convergent section being connected to a first end of the mixing chamber to define a venturi therebetween;
• and
• a diffuser section connected to a second end of the mixing chamber:
• the apparatus further comprising:
• an opening in the secondary flow pipe arranged to provide fluidic communication between the second flow passage and the mixing chamber;
• a turbine connectable to a generator and arranged to be rotated by water flow from the second flow passage;
• and
• a flow control mechanism for directing the water flow from the second flow passage through the opening into the mixing chamber, where water flowing from a first direction flows into the mixing chamber from one end of the base structure and water flowing from a second direction flows into the mixing chamber from the opposite end of the base structure, and where the flow control mechanism is configured to block the water flow through an entire length of the second flow passage and is configured to control the direction of the water flow so that all water entering the primary and secondary flow pipes discharges via the primary flow pipe;
• and
• at least one barrier located across the top of the base structure.
