Inside the module
Every layer is listening.
- 01 Smoked-glass lid
- 02 Sensor mesh: heat, voltage, gas, pressure
- 03 Cell lattice, watched cell by cell
- 04 Thermal plate with fluid channels
- 05 Armoured housing and isolation
Concept rendering. Layer functions describe design intent.
The prediction horizon
Scroll through a fault. Watch it get caught.
Simulation for illustration only. Timings and behaviour show design intent, not measured performance.
The grey-swan record
Known. Foreseeable. Still happening.
A grey swan is a risk everyone knows exists, but few expect to face today. These are real incidents, with public sources.
