A star here on earth: the future of fusion will power the world | Bob Mumgaard #ECDemoDay

Fusion energy represents the ultimate transition from finite natural resources to a scalable technology capable of providing limitless, clean power. Bob Mumgaard, CEO of Commonwealth Fusion Systems, details the development of SPARC, a demonstration device outside Boston designed to replicate the stellar fusion process on Earth by 2027. This advancement relies on breakthrough magnet technology—capable of lifting battleships—to confine and heat hydrogen fuel to over 100 million degrees. By replacing existing fossil fuel plants with fusion reactors, this technology can meet the massive energy demands of artificial intelligence and deep decarbonization efforts. Unlike intermittent renewables, fusion operates independently of weather conditions and offers a path toward a hundredfold increase in global energy capacity. This shift promises to transform human civilization on a scale comparable to the Industrial Revolution, moving society toward a future defined by energy abundance rather than consumption-driven scarcity.
