China's EAST project has set a new global record by maintaining a high-confinement plasma state for over 17 minutes, paving the way for future clean energy solutions by mimicking the sun's fusion process. China's Experimental Advanced Superconducting Tokamak (EAST), also known as the "artificial
I don’t know about weaponizing anything, but I do know the only energy positive fusion reaction was done by making a little pellet of hydrogen, carefully aligning a room full of lasers, and then zapping it into helium. Each time they did it, someone had to walk into the chamber to put in the pellet, and they’d have to spend a few hours aligning the lasers again.
You get more energy out than you put in, but it just doesn’t scale.
