EUV lithography is interesting. You drop a microscopic droplet of tin. You then aim and shoot it not once, but twice with a laser so it produces the correct wavelength. Then you do this with 100% reliability thousands of times per second all day, every day for years. The problem doing this with fusion seems to be money. Their "big" grant of 600M wouldn't even buy a handful of those machines and wouldn't come close to the many billions it has cost in the past 30+ years of research to reach the point where they are finally viable (it had been "a few months away" ever since the early 2000s). This video from Asianometry on EUV light sources is well worth the watch. It's pretty incredible. https://www.youtube.com/watch?v=5Ge2RcvDlgw https://www.youtube.com/watch?v=5Ge2RcvDlgw
