General Fusion debuted on the Nasdaq Monday — the first pure-play publicly traded fusion power company.
Jeff Bezos made his first investment in General Fusion in 2011.
→ Fourteen years,
→ several near-death funding crises, and
→ one 25% staff layoff later, the company rang the Nasdaq bell Monday as GFUZ ( ▲ 25.09% ) — the first pure-play publicly traded company betting it can commercialize nuclear fusion. |
The stock popped hard on debut day. The company's own technology is currently running at less than a tenth of the temperature it needs to work.| What They're Actually Trying To Build? | | General Fusion is trying to recreate the reaction that powers the Sun—inside a machine on Earth. | | Instead of burning fuel like a conventional power plant, the goal is to fuse hydrogen atoms together. If successful, that reaction would release enormous amounts of clean energy. | | Magnetized Target Fusion, Explained | 1\ Create plasma
Magnetic fields generate an ultra-hot cloud of charged gas called plasma—the same state of matter found inside stars. | 2\ Contain it
The plasma sits inside a chamber surrounded by liquid lithium. | 3\ Compress it
Dozens of mechanical pistons fire at the same time, squeezing the liquid lithium inward and crushing the plasma. | 4\ Trigger fusion
If the temperature and pressure become high enough, hydrogen atoms fuse together, releasing energy. | | Unlike many competitors that rely on massive superconducting magnets or powerful lasers, General Fusion uses a combination of mechanical compression and magnetic fields.
The company believes that approach could make future fusion power plants simpler and less expensive to build.| How Close Are They? | | General Fusion's biggest challenge is making fusion actually work. | | Three major scientific milestones still separate today's machine from a commercial reactor. | | | The most important number isn't 100 million°C. | | It's 8.4 million°C. | | That's the company's current best result—still below its own first milestone. | | Reaching 100 million°C would represent another order-of-magnitude leap. Beyond that comes the industry's defining hurdle: the Lawson Criterion, the point where a fusion reaction produces more energy than it consumes. | | That milestone is targeted for 2028. | | It simply mean investors are buying a company that still has several major scientific breakthroughs ahead of it before anyone can talk about commercial electricity. | Even CEO Greg Twinney describes the company's 2035 power plant target as an "optimistic scenario."
