At the intersection of these lanes is a place where ideas on finance, technology and policy are shared and debated. That intersection is Interchange Recharged. Your host is Sylvia Leyva Martinez, principal analyst and research director at Wood Mackenzie. When Sylvia isn't tracking the technologies and markets driving the build-out of renewable power, she's speaking with visionaries, entrepreneurs, policy-makers and energy analysts to explore the newest developments in renewable technology, explain the ideas on global energy policy that could accelerate the energy transition, and identify new funding and financial models that could solve the biggest challenges we face on the way to net zero. Sylvia and her guests bring you data and forecasts on clean technology, climate science, and offer predictions on the build out of utility-scale projects and the future of green finance. What does the surge in data-centre demand mean for the grid, and who pays for it? What's happening in global EV adoption and development? What's the forecast for solar, one of the major succ…","last_synced_at":"2026-09-16T02:19:58.805362+00:00","page_url":"https://stenobird.com/podcast/interchange-recharged-1117793"},"episode":{"title":"As racks scale, power must change: The AC-to-DC rethink inside AI factories","slug":"as-racks-scale-power-must-change-the-ac-to-dc-rethink-inside-ai-factories","published_at":"2026-06-30T11:00:00+00:00","page_url":"https://stenobird.com/podcast/interchange-recharged-1117793/as-racks-scale-power-must-change-the-ac-to-dc-rethink-inside-ai-factories","show_page_url":"https://stenobird.com/podcast/interchange-recharged-1117793","url":"https://dts.podtrac.com/redirect.mp3/rss.art19.com/episodes/d9051aad-ffcf-4e36-979a-14b3ab25b81c.mp3?rss_browser=BAhJIg90cmFuc2NyaWJyBjoGRVQ%3D--952c5701c84ad333c69d5faa668f8177091704f0","audio_url":"https://dts.podtrac.com/redirect.mp3/rss.art19.com/episodes/d9051aad-ffcf-4e36-979a-14b3ab25b81c.mp3?rss_browser=BAhJIg90cmFuc2NyaWJyBjoGRVQ%3D--952c5701c84ad333c69d5faa668f8177091704f0","summary":"As AI systems scale, the infrastructure challenge is no longer just about chips, models, and software performance. It is increasingly about the physical systems that allow computation to happen at all: power delivery, cooling, water access, and the speed at which new capacity can be brought online. Power conversion is becoming a much more important design question. As racks move from conventional power densities toward megawatt-scale configurations, every inefficiency in the electrical pathway becomes more consequential. For stakeholders across the energy sector, that makes AI infrastructure more than just a datacenter story. It is also a story about grid constraints, industrial load growth, thermal management, and how developers can design facilities that are efficient enough, flexible enough, and resilient enough to operate at the scale AI now demands. Host Sylvia Leyva Martinez is joined by Nick Wright, Vertical Solutions Manager at Siemens. Their conversation explores why the growth of the AI factory is pushing operators to rethink traditional electrical architecture, especially the number of conversion steps required to move power from the grid to the chip. Nick explains why conventional AC-heavy setups are under pressure as compute loads become denser, more dynamic, and more power-intensive, and why more direct AC-to-DC pathways are drawing increased attention. The episode also examines what that shift means in practice: less energy lost in conversion, less excess heat to manage, different implications for cooling design, and a growing role for higher-voltage DC systems, digital twins, monitoring technologies, and new protection equipment. Along the way, the discussion widens beyond the building itself to consider how AI facilities may evolve into more grid-aware…","meta_description":"As AI systems scale, the infrastructure challenge is no longer just about chips, models, and software performance.
