General Fusion fires up its newest steampunk fusion reactor

Good news!

"General Fusion announced on Tuesday that it had successfully created plasma, a superheated fourth state of matter required for fusion, inside a prototype reactor. The milestone marks the beginning of a 93-week quest to prove that the outfit’s steampunk approach to fusion power remains a viable contender.

The reactor, called Lawson Machine 26 (LM26), is General Fusion’s latest iteration in a string of devices that have tested various parts of its unique approach. The company assembled LM26 in just 16 months, and it hopes to hit “breakeven” sometime in 2026.

General Fusion is one of the oldest fusion companies still operating. Founded in 2002, it has raised $440 million to date, according to PitchBook. ..."

"General Fusion’s Magnetized Target Fusion (MTF) demonstration, Lawson Machine 26 (LM26), has successfully formed a magnetized plasma in the machine’s target chamber—a significant achievement in the operation of this world-first machine. LM26 is now forming plasmas daily as General Fusion’s team optimizes performance in preparation for its next step—compressing plasmas with a lithium liner to create fusion and heating from compression. ..."

"General Fusion’s Magnetized Target Fusion (MTF) technology is designed to scale for cost-efficient power plants. It uses mechanical compression to create fusion conditions in short pulses, eliminating the need for expensive lasers or superconducting magnets. An MTF power plant is designed to produce its own fuel and inherently includes a method to extract the energy and put it to work."
