Investigation of viability of seasonal waste heat storage in rock piles for remote communities in cold climates
Bibliographic record
Abstract
Communities situated in distant areas are deemed as 'remote' and have either very limited or no access to power grid lines. Therefore, most of these communities greatly depend on diesel-burning for power and heat provision at all times. Nonetheless, nearly 30% of the energy associated with the diesel burning and power generation process is dissipated as heat through the exhaust streams of diesel generators. The waste heat in the exhaust stream is usually recovered during the winter season and directly used as a heat source when the communal heat demand is peaked. However, recovery of this energy potential is usually discarded during the summer period due to the low demand. Seasonal thermal storage on rock piles is a developing concept that can be a low-cost solution to resolve this issue. This paper proposes utilization of the heat wasted through the exhaust stream of diesel generators on rock piles as temporary storage during low demand times. In this sense, a remote cold climate community, such as those of Canada and Norway, is selected and potentiality of the seasonal rock pile thermal storage is investigated and presented.

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.
