The Fusion General announced on Tuesday that it has successfully created plasma, the fourth substance required for fusion, inside the prototype reactor. The milestone is a 93 -week quest, and proves that the steam punk approach to the costume for fusion power remains a competitor.
The reactor called Lawson Machine 26 (LM26) is the latest repetition of General Fusion in a series of devices that tested various parts of unique approaches. The company assembled LM26 in just 16 months and hopes to hit “Breakeven” in 2026.
General Fusion is still one of the oldest fusion companies. Founded in 2002, the company has raised $ 440 million. During that period, I saw a rising competitor and failed, including promises made 20 years ago, as if the fusion industry was written.
Fusion Power has two points that say the response is good. What most people think is called commercial failure. At that time, fusion reactions can produce more power than the entire facility consumes, allowing power plants to put electricity into the grid. No one has reached this milestone yet.
The other is known as Scientific Breakeven. In this case, the fusion reaction must generate at least a lot of power as it is directly delivered to the fuel. Scientific Breakeven only examines the rest of the facility and only look within the boundaries of the experimental system. Nevertheless, it is an important milestone for convergence attempts. So far, only the national ignition facilities of the US Energy Bureau have reached.
The approach of General Fusion for Fusion Power is very different from other startups. The MTF (Magnetized Target Fusion) is similar in relation to some inertia. The National ignition facility is used to prove that the National IGTITION facility used in the late 2022 can produce more power than what the convergence reaction begins.
However, if the national ignition facility compresses the fuel pellet using a laser, the MTF reactor design of the fusion depends on the steam drive piston. The inside of the chamber, the heavy hydrogen-triple fuel contains a little electricity to create a magnetic field, which helps to include plasma. The piston then compresses the liquid lithium wall inward from the plasma.
When the fuel is compressed, the temperature rises until the fusion reaction occurs. The reaction then heats the liquid lithium, and the company will circulate through heat exchanger to create steam and rotate generators.
The MTF emerged in the US Naval Research Laboratory in the 1970s, and researchers were developing a concept of small convergence reactors. The effort did not bear fruit. Fusion General says the piston that compresses the liquid liner is not accurately controlled, and modern computers now provide a better opportunity to run complex choreography.
Whatever the LM26, the Fusion General is still making more effort. The device does not have liquid lithium walls and instead depends on solid lithium compressed by electromagnetically. This limits the number of tests that the company can do because it takes more time for the company to reset the device. The company conducted more than 1,000 tests to check how it lasts over time, but integrating everything is still a monumental engineering task.
Nevertheless, the switch of the LM26 is an important stage of a company that races to provide a power plant with many new students with their deep pockets and aggressive timelines.
