While the world fights over chips, one company is building the power supply to run them all. In this episode of The Generalist, I'm joined by Bob Mumgaard, CEO and co-founder of Commonwealth Fusion Systems (CFS), and Vinod Khosla, legendary venture capitalist and founder of Khosla Ventures. With over 800 employees and $2 billion in funding, CFS has accelerated the timeline for commercial fusion from being perpetually "30 years away" to potentially just a few years out. If CFS succeeds, it will unlock limitless clean energy for humanity, powering everything from AI to water desalination.
In our conversation, we explore:
• How fusion could transform everything from AI to water desalination and agriculture
• The fundamental science behind fusion energy and how it differs from traditional nuclear fission
• The breakthrough in magnet technology that changed the timeline for fusion
• The strategic approach of partnering with existing power plant operators to rapidly scale fusion deployment
• Why fusion is essential for powering AI and other energy-intensive innovations
• CFS’s method for creating fusion using magnetic fields
• The final hurdles to completing SPARC, the company’s demonstration reactor
• The six-stage roadmap for fusion development, where CFS currently stands, and when they expect to begin delivering power to the grid
• What clean energy could make possible for future technologies and industries
• The geopolitical implications of a world with abundant clean energy
• Much more
