Abstract
Numerous researchers have proposed phase change materials (PCMs) as an alternative for increasing the autonomy of solar water heaters (SWHs). Many studies have considered SWHs with PCMs in three main configurations: PCMs inside the solar thermal collector, inside a coupled heat storage unit, and within the water storage tank. A wide range of topics has been explored within studies assessing SWHs with PCMs in recent years, including but not limited to enhancement techniques for improving heat transfer, optimization strategies, economic factors, weather exposure on performance, and the application of design methodologies. This article reviews and discusses recent work on these trending topics, identifies research opportunities, and suggests promising research efforts toward more mature SWHs with PCM technology, focusing on long-term performance, scalability, economic, and technical feasibility.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
