A Star in a Bottle: The Quest for Commercial Fusion

“Produce more power than it consumes.”

September 2021

On Sept. 5, 2021, for the first time, a large high-temperature superconducting electromagnet was ramped up to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created on Earth.

 That successful demonstration by the PSFC and CFS helps resolve the greatest uncertainty in the quest to build the world’s first fusion power plant that can produce more power than it consumes.
