Dr. Richard Bonner, CTO at Accelsius: The Two-Phase Cooling Revolution for AI-Driven Data Centers

Two-phase cooling isn’t new - but it’s never been more needed.

In this episode, Dr. Richard Bonner of Accelsius joins Robert to unpack how a decades-old thermal principle, once used in industrial processes, is being reimagined to meet the explosive demands of AI and high-power GPUs.

They explore Accelsius’ patented two-phase cold plate technology - originally developed at Bell Labs - and how it’s being commercialised to deliver unmatched reliability, redundancy, and sustainability. From N+1 pump systems to the role of two-phase in future data center architectures, this episode covers everything from thermal physics to practical deployment strategies.

If you’re curious about the roadmap to next-gen cooling, the reality behind liquid vs. immersion, or what’s actually going to enable the Rubin generation of chips… this episode is for you.
