Thanks to powerful new magnet technology, researchers at Massachusetts Institute for Technology (MIT), created a much smaller, less-expensive ARC reactor, that would deliver the same power output as a much larger fusion reactor. 

They say, that it’s one that might be realized in as little as a decade.

The era of practical fusion power, which could offer a nearly inexhaustible energy resource, may be coming near.

Using these new commercially available superconductors, rare-earth barium copper oxide (REBCO) superconducting tapes, to produce high-magnetic field coils “just ripples through the whole design,” says Dennis Whyte, a professor of Nuclear Science and Engineering and director of MIT’s Plasma Science and Fusion Center. “It changes the whole thing.”

Co-authored by Whyte, PhD candidate Brandon Sorbom, added:

“The much higher magnetic field, allows you to achieve much higher performance. Any increase in the magnetic field gives you a huge win.”
