MIT physicists inch closer to zero-emissions power source

Sept. 29 (UPI) — For the last few years, scientists at MIT have been working on a fusion research experiment called SPARC and, according to a series of papers — published Tuesday in the Journal of Plasma Physics — the research is going quite smoothly.

The research effort, a collaboration between MIT and startup company Commonwealth Fusion Systems, is intended to pave the way for an emissions-free power plant — a fusion reactor.

According to the latest updates, scientists have yet to encounter any unexpected hurdles. What’s more, researchers characterized the remaining challenges as manageable.

Over the last 2 1/2 years, researchers on the project have focused on working out the physical principles underlying their planned fusion reactor. So far, the work has confirmed the validity of the plasma physics behind their SPARC plans.

“These studies put SPARC on a firm scientific basis,” Martin Greenwald, researcher at the MIT Plasma
