‘We have to all do this together or it’s not going to happen’

An international cohort of nuclear experts are combining advanced computing, magnetics, sensors, and their own expertise as they work to expedite sustainable fusion reactions,

to a press release on the Spain-based project.

A description from Princeton Plasma Physics Laboratory describes it as an effort to “solve the world’s energy crisis.”

“We have to all do this together or it’s not going to happen,” Jack Berkery, Princeton’s principal investigator for the project, dubbed the SMall Aspect Ratio Tokamak,

The Princeton team is working with experts from the University of Seville to figure out a reliable, cost-effective way to fuse plasma to create cleaner energy. Unlike fission — the common reaction used in the world’s approximately

But teams of scientists are working on groundbreaking techniques to harness the nearly everlasting power, including the largest tokamak in the world, located in France.

The researchers are experimenting with plasma’s shape — classified as positive or negative — inside the tokamak. Their tinkering with its “triangularity” could help suppress instabilities. The team arrived at a spherical tokamak and a negative-oriented triangularity,

to the research summary.

“It’s a potential game changer with attractive fusion performance and power handling for future compact fusion reactors,” Seville Professor Manuel Garcia-Munoz said.

The effort also leverages Princeton’s expertise in magnetics and diagnostic sensors, which can operate for decades, per the summary.

Should we be pouring money into nuclear fusion technology?
