Bidirectional Tidal Energy Conversion System
Bibliographic record
Abstract
This paper introduces a novel tidal energy conversion concept specifically designed for low-range tidal environments (~1 m), where conventional tidal technologies are ineffective.The system employs a buoyancy-countermass coupled hydraulic design, capturing energy during both tidal uplift and gravitational descent.This bidirectional approach enables full utilization of tidal displacement, in contrast to turbine-based systems that harness only part of the flow.Key performance results indicate an overall efficiency of approximately 77%, straightforward modular scalability through caisson dimensioning and replication, and technical feasibility using existing offshore engineering practices.Together, these outcomes show that the system can be practically realized and adapted to different site conditions.By demonstrating that both feasibility and scalability are achievable, the study positions the proposed design as a practical foundation for new tidal energy solutions in underserved coastal regions.The concept represents a significant contribution to ocean energy research by showing that useful power can be generated even under minimal tidal ranges.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
