Wright's Law
Wright's law says unit cost falls a fixed percentage each time cumulative production doubles — the engine behind Kronos's LCOE decline.
- Statement
- Cost falls a fixed % per doubling of cumulative output
- Also called
- The learning or experience curve
- Kronos use
- Drives the FOAK → NOAK → fleet cost ladder
- Structural edge
- Avoids the 33–42% D–T availability penalty
Wright's law — first observed in aircraft manufacturing in 1936 — states that the cost of a manufactured unit falls by a consistent percentage every time cumulative production doubles. It is the empirical engine behind the dramatic cost declines of solar panels, batteries, and other mass-manufactured technologies, and it is why building more units matters as much as designing a cheaper one.
Kronos applies Wright's law to its LCOE ladder: cost drops from a first-of-a-kind $84–92/MWh toward a fleet-scale $48–56/MWh as cumulative units accumulate. A low-neutron plant compounds the effect, structurally avoiding the 33–42% availability and LCOE penalty that neutron-heavy D–T concepts carry from frequent blanket changeouts.
