The sheets. Nothing else pretending to be a picture.

Compact linear Fresnel pod

40 m² single-axis pod, Cg = 50, 8 m receiver rail, 0.80 m² illuminated area. Trough remains Option B.

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.

Class-M receiver rail tile

400 mm oil cartridge. Absorb and extract only, 250–390 °C. The cold tile uses the same rail datum and is a different part. It is not drawn.

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.

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.

Temperature classes

L water, M oil, H salt, X research. The product is dispatchable heat, not cheaper bulk electricity than silicon.

Disc expander cutaway

Picture only. Dimensions on the image are not a release.

Picture only. The millimeters on this image are not a stack-up. Disk count, gap, and diameter stay open until the oil header exists.

How vapor turns the shaft

Picture only. Dimensions on the image are not a release.

Picture only. Hot oil, evaporator, nozzle, pack, hub, shaft. Ignore any dimension printed on the image.

Disk pack

Picture only. Dimensions on the image are not a release.

Picture only. Repeating disks. Gap is an open variable inside 0.4–1.0 mm, not the number drawn on the sheet.

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.

Uncertainty budget

G0 is not a nominal close. Report Pin and Puse with uncertainty. Residual must be compatible with the propagated budget.

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

Archive. The slogan on this sheet was retired. Receivers split. They do not slowly become one hybrid tile.
