Abstract
A dual-dish concentrating solar research system is introduced in which multiple low-cost single-axis-focusing mirrors have their foci overlapped into a single intense compound focus. A CPV receiver for such a focus is also introduced, with cooled secondary mirrors and a Dense Receiver Array (DRA) with shingled cell rows to eliminate inter-row gaps. CTE-matched micro-channel cold plates are used for low-resistance cooling and fin tube radiators provide ample heat-rejection surface. The ratio of the DRA’s cell area to focusing mirrors’ area allows reaching a concentration factor of 1000x. A cost breakdown is presented and discussed and areas that still need significant improvement to be able to compete with flat panel costs are identified, along with research works in progress in those areas.

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
