E10 - AI Cooling And Data Centers With Cliff Federspiel

In this episode, we sit down with Cliff Federspiel, President and CTO of Vigilent, to explore how AI driven control systems are reshaping data center cooling, energy use, and operational reliability. Cliff shares his journey from academic research and HVAC controls to founding Vigilent during the 2008 financial crisis, and why predictive, model based AI is very different from large language models. The conversation dives into data center realities such as rising rack densities, liquid cooling, power constraints, and the operational value of reducing alarm noise. Along the way, Cliff reflects on leadership, transparency, convincing others to believe, and the hard lessons learned building a company through uncertain times.

E9 - Building Hyperscale AI Data Centers in Rural America With Wes Cummins

In this Baxtel Podcast episode, Eric Bell sits down with Wes Cummins, CEO of Applied Digital, to unpack how hyperscale AI data centers are being built far from traditional metros. Wes shares why power availability and fiber routes matter more than population density, and how rural communities like Ellendale, North Dakota benefit economically from large-scale campuses. He walks through Applied Digital’s evolution from Bitcoin mining facilities to purpose-built AI and HPC infrastructure, including lessons learned around InfiniBand design, power density, and future-proofing for NVIDIA’s roadmap. The conversation also explores grid power versus behind-the-meter generation, community misconceptions about data centers, and why long-term, investment-grade hyperscale contracts shape Applied Digital’s strategy.

E8: Inside ERCOT, Black Start, Winter Storm Uri, and AI Data Center Load

In this episode, Eric Bell sits down with Russell Fletcher to unpack what it really means to operate a modern power grid in Texas. Russell shares how ERCOT keeps generation and load balanced at 60 Hz, why transmission congestion matters as much as megawatts, and what “black start” recovery looks like when the grid goes dark. They revisit Winter Storm Uri, including how close Texas came to a statewide blackout, and discuss the growing challenge of fast-ramping AI data centers, behind-the-meter generation, and reactive power. Along the way, Russell connects lessons from Navy nuclear submarines to grid operations, where calm, training, and clear communication can make all the difference.
