About this episode

The episode explores Walt Disney's vision for a nuclear-powered city and its implications for innovation and technology.

What if Walt Disney had actually built the city of the future—powered by nuclear energy? In the Season 5 premiere of Fissionary, hosts Mary Carpenter and Jordan Houghton sit down with urban planner and author Sam Gennawey to uncover how Walt’s imagination extended far beyond theme parks. From Disneyland to his unrealized vision for Epcot, Walt dreamed of communities built around innovation, clean power, and human connection. Sam shares how those plans included a nuclear-powered city under a climate-controlled dome, what it reveals about Disney’s faith in technology, and why his “yes, if” philosophy still matters today.
