Blueprints
These are engineering sheets, not marketing. Rev C is what we will be wrong about in public.
Revision C
Compact linear Fresnel pod
40 m² single-axis pod, Cg = 50, 8 m receiver rail, 0.80 m² illuminated area. Trough remains Option B.
Phase A instrumented rig
2.0 m² dual-axis facets, 25×, 400 × 200 mm cavity, water calorimeter 80–120 °C. Close the energy balance first.
Class-M receiver rail tile
400 mm tile, absorb and extract only. Thermal oil 250–390 °C. Same envelope reserved for a later hybrid tile.
How the rail eats light
Field → 100 mm slot → cavity → two DN15 tubes. Cg is geometry. The coating sees q''(x,y). Oil leaves at 390 °C.
Temperature classes
L water, M oil, H salt, X research. The product is dispatchable heat, not cheaper bulk electricity than silicon.
Uncertainty budget
G0 is not a nominal close. Report Pin and Puse with uncertainty. Residual must be compatible with the propagated budget.
Receiver-plane flux fixture
Cg is geometry. C_flux(x,y) = q''(x,y)/DNI is what coatings, tubes, and later CPV actually see.
Class-M storage and header
Two-tank thermal oil, QD header, expansion tank. Dispatchable heat is the product. The field does not move.
Secondary CPC and dump-focus
Intercept without a tiny aperture. Hardware interlock to dump on loss of tracking, flow, or over-temp.
Model M1 optical budget
η_opt from reflectance, IAM, blocking, CPC intercept, and end loss. C_flux(x,y) is the map. Cg is only geometry.

Field + receiver architecture
Early field concept. Rev C replaces the single tiny aperture with modular receiver area sized from Cg = Ac / Ar.
Engineered receiver cartridge
Archive cutaway. Rev C splits temperature regimes: only functions that must sit at optical focus stay in the tile.
Selective stack and cavity physics
Cavity reabsorbs internally emitted radiation. The aperture still radiates. Geometry is part of the optical design.
Energy paths and exergy split
Electricity, stored heat, process heat. Chemistry is optional and later. Count every joule.
Instrumented prototype (archive)
Superseded by XP-C01 Phase A. Kept for the measurement list and energy-balance equation.
Product family and upgrade path
The field stays. Receivers evolve. Dates in this sheet are replaced by promotion gates in Rev B/C.
