Can Fusion Energy Really Power the Future? With Alex Creely, Commonwealth Fusion Systems

What does it really mean to “build a star on Earth”?In this episode we explore one of the most ambitious clean-energy ideas of our time: fusion power. Joining us is Alex Creely, a plasma physicist and tokamak operations lead at Commonwealth Fusion Systems, who has spent nearly a decade working to turn fusion from a scientific breakthrough into a practical energy source.Alex breaks down fusion in refreshingly human terms and explains why something that sounds simple is one of the hardest engineering challenges humanity has ever taken on. We talk about why fusion has always felt “just around the corner,” what has changed in recent years, and why the next decade could be pivotal.Along the way, the conversation expands beyond science. We examine fear and misconceptions around nuclear energy, how fusion differs fundamentally from fission, and why big innovations often take decades of quiet progress before they suddenly feel inevitable. This is a conversation about patience, curiosity, risk-taking, and what it means to work on something that may not pay off immediately, but could change everything.In this episode:What fusion energy actually is, and how it differs from nuclear fissionWhy fusion requires temperatures hotter than the center of the sunThe challenge of producing more energy than it takes to sustain the reactionHow powerful magnets act as “insulation” for 100-million-degree plasmaWhy recent breakthroughs have shifted timelines from distant to tangibleHow fusion could complement wind and solar, especially for dense citiesThe infrastructure, cost, and policy challenges of scaling fusion globallyWhat everyday people can do to support fusion’s futureWhy the most impactful work always carries uncertainty and riskAbout Our GuestAlex Creely is a plasma physicist and tokamak operations lead at Commonwealth Fusion Systems. His work focuses on advancing fusion energy from laboratory research to grid-ready infrastructure. Known for his ability to explain complex science in accessible ways, Alex is part of a growing group of scientists working to make clean, firm fusion power a reality.Be part of the Bluedot Living communityAt Bluedot Living, we imagine if people were actually making progress on climate change—because they actually are.
