This bundle is the densest part of the archive. It contains the development notes for Cool Cell, Di-thermal roofs, storage, pool-heater cooling, plate testing, double play, and related experiments. Many of the later concept pages come directly out of this year.
| Family | Files | What they contribute |
|---|---|---|
| Cool Cell / di-thermal roof development | 7 files | Core system evolution. |
| Storage and cloudy-day notes | 10 files | Thermal storage variants. |
| Pool-heater cooling | 6 files | Retrofit cooling path. |
| Plate tests / night cooling | 3 files | Numerical grounding. |
| Double play / list attendees | 2 files | Architectural / cultural side-stream. |
hardware experiments + storage variants + measurement notes = the engineering core
The bundle is a raw-source summary, not a conclusion page. It preserves provenance for the file family and points to the compiled concept pages that already distill the ideas.
