Abstract
This chapter presents the current status, issues and future developments of tidal energy technology. Tidal power facilities can be categorized into two main types: tidal barrages and tidal current turbines, which use the potential and kinetic energy of the tides, respectively. Numerous tidal sites worldwide are considered suitable for development; however, only four tidal barrage power plants are in operation. The four power plants are La Rance tidal power station in France, Annapolis tidal generation, Bay of Fundy, Canada, Kislaya Guba power facility, Russia, and Jangxia Creek, East China sea. Some of the larger sites currently undergoing feasibility studies include the Severn Estuary in the UK, Bay of Fundy in Canada, Mezen&s; Bay and Tugar Bay in Russia, and the Wash, the Mersey, the Solway Firth, Morecambe Bay and the Humber Estuary in UK. A considerable number of potential tidal barrage sites have been identified for large-scale electricity generation, although only four tidal barrages have been constructed to date.

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.
