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.

Craig MacFadyen is back on the podcast - this time fresh from the floor of the OCP Global Summit in Dublin.

In this episode, Craig and Robert dig into the real conversations happening around liquid cooling, hyperscaler expectations, and whether the data center world is preparing for a future that hasn’t quite arrived yet.

From CDUs and 500kW rack forecasts to the tension between innovation and affordability, they tackle the practical, the political, and the philosophical challenges facing data center cooling in 2025. Craig also shares his perspective on startup tech, smarter not newer design, and why collaboration still feels more talked about than practiced.

It’s an honest, thought-provoking follow-up to Craig’s first appearance - don’t miss it.

🎧 Topics include:

• Key takeaways from OCP 2025
• The rise of rack density and the “500kW by 2030” challenge
• How hyperscalers are influencing the market—and when adoption will really happen
• The innovation bottleneck caused by NDAs and over-regulation
• What smart design actually looks like in cooling
• The role of power availability and why cloud still dominates over AI

Is AI truly revolutionising the way we understand clients and employees? Or is it just another buzzword being tossed around?

In this episode, Ryan Scott, Chief Technology Officer at DNA Behavior, joins me to break down the real-world impact of AI in behavioural data analytics. We dive into how DNA Behavior is leveraging AI to predict client behaviour with 70% accuracy - without even requiring a questionnaire. Ryan and I explore the shift towards decentralised AI, the challenges of integrating AI-driven insights into enterprise workflows, and the ethical dilemmas of AI-powered sales intelligence.

As data centres race to support the growing compute demand for AI, will AI factories dominate, or will the future lie in edge computing? And with AI accelerating at an unprecedented pace, what safeguards are needed to ensure responsible development?

From Microsoft’s AI-driven infrastructure expansion to the challenges of balancing transparency with competitive advantage, this episode unpacks the key questions shaping AI’s future.

Tune in for an insightful discussion on AI, ethics, and where the industry is heading next.
