This bundle gathers the 2025 recap material: modern Cool Cell writeups, a pool-heater cooling note, shareholder commentary, Di-thermal roof updates, and a double-play thermosiphon note. It is the archive looking back at itself.
| Family | Files | What they contribute |
|---|---|---|
| Cool Cell recap | 2 files | Modern re-description of the system. |
| Pool heater / cloudy heat | 2 files | Re-statement of the cooling/storage argument. |
| Di-thermal system | 2 files | Updated roof/system framing. |
| Public-facing notes | 2 files | Journal / shareholders context. |
| Double play thermosiphon | 1 file | Later retrospective linkage. |
retrospective recap + modern framing = archive continuity
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.
