262 - Fire Fundamentals pt. 22 - Optical diagnostics in fire with Elizabeth Weckman

In todays episode of fire fundamentals we talk with Professor Elizabeth Weckman from University of Waterloo about advanced optical diagnostics that let fire researchers read temperature, chemistry, soot, and velocity from light without relying only on probes. We break down what cameras, infrared imaging, spectroscopy, lasers, and PIV can reveal, plus the calibration and interpretation pitfalls that can quietly ruin your data. Things covered in this episode: • why optical diagnostics are...

260 - Fire safety in a carbon budget with Cecilia Wetterqvist and Axel Mossberg

A carbon budget can feel like a hard wall in modern building design, and once you treat CO2 as currency, everything starts competing for a slice of it. The problem is that fire safety systems often sh...

258 - e-mobility fires in trains with Adam Barowy

A battery fire on a train is not “just another small fire.” When a lithium-ion battery in an e-scooter or e-bike fails, the rail car can behave like a long pipe that moves smoke fast, limits escape op...
