The Availability Gate

The burner's modelled availability is 0.86-0.995 against a hyperscale Tier III target of 0.99982 — 30 to 100 times more downtime, and the central honest limit of the data-center case.

The number that governs everything

Availability is the fraction of time a system is up and delivering. Hyperscale operators design to Tier III, roughly 0.99982, which allows about 1.6 hours of downtime per year. The Kronos burner, as a design-and-simulation study, models availability between 0.86 and 0.995. The low end is about 49 days of downtime a year; even the high end is about 1.8 days. Against Tier III that is 30 to 100 times too much downtime.

This is a physics-and-engineering fact, not an economic one, and it is stated plainly because it is load-bearing for every data-center claim on this site. A machine this early in its life — high-field superconducting plugs, a demanding plasma regime, first-of-a-kind subsystems — does not yet demonstrate the reliability of mature infrastructure. Pretending otherwise would be dishonest and would fail the first serious technical review.

The consequence is architectural, not fatal. A source cannot be a sole Tier III supply at 0.86-0.995, but it can be the firm base layer of a redundant system whose combined availability reaches Tier III. That is the entire logic behind pairing the burner with N+1 units, a storage layer, and a grid tie. The gate defines the design; it does not cancel it.

Everything else on these pages should be read through this gate. Where the burner is described as firm, it means firm-within-a-hybrid. Where it is described as 24/7, it means 24/7 with redundancy carrying the outages. The honest target date for even a test unit is near 2032, with a commercial fleet near 2036.
