Scientists Just Took a Giant Step Toward Scaling Up Nuclear Fusion

A team of researchers at MIT think they may have lowered one of the major barriers to achieving large-scale nuclear fusion—taking us one step closer to making an abundant form of energy a reality.

By harnessing the same processes that power stars, we would have access to a clean, safe, and practically limitless energy source. Scientists have built reactors to try and tame fusion, with one of the most explored being the tokamak. Essentially a donut-shaped tube that uses strong magnets to…
