One pod
40 m² collector, 0.80 m² rail. A house, not a business.
PR-B01 / PR-C01
System architecture
Cheap mirrors in the dirt. A hot pipe they all point at. Tanks, turbines, and science experiments sit downstream — not on the focus. The field stays. Receivers evolve.
PR-C01 · Compact linear Fresnel · Cg = 50
Governing relation
Cg = Ac / Ar
Use effective illuminated receiver area, not the physical shell. For a 40 m² pod at 50× the receiver is 0.80 m². A 5,000 m² field at 50× needs about 100 m² of receiver, distributed across many tiles — never a 6–8 inch aperture.
Pin = DNI × Ac
Incident solar power on collector aperture.
Prec = Pin × ηopt
Optical efficiency includes reflectance, cosine, shading, intercept, and secondary losses.
Prad ≈ ε σ Aap T⁴
A cavity shrinks radiating area toward the aperture. It does not cancel T⁴.
ηth = Puse / Pin
System thermal efficiency after radiation, convection, and leak. Match temperature to the load.
Architecture rules
- R1
No single point in the optical chain may rely on an unverified ultra-high concentration ratio.
- R2
Receiver area is derived from collector area and target concentration before dimensions are drawn.
- R3
Components not required at optical focus are moved downstream for cooling, service, and safety.
- R4
Each receiver generation must fit the same mechanical / thermal / electrical interface envelope.
Scale-out
Ten-pod cluster
400 m² collector. Shared thermal header. One tile can fail without retiring the field.
First island
120 pods, 4,800 m² collector, ~2.6 acres. Service aisle for cartridge swap.
