While it’s always good to be a bit skeptic, don’t take this video at face value either. I’d argue that it has bigger issues than Real Engineerings video because it tries to come off as scientifically accurate, but may actually be deeply flawed. See comments on this Reddit post for some deep discussion: https://www.reddit.com/r/fusion/comments/10g95m9/comment/j67...

Real Engineering has a tone where - while I do think they usually keep a high standard - I don’t assume that they’re necessarily 100% correct or that the new technology they cover is necessarily viable. With both Spinlaunch and Helion I just came out of it with the feeling “cool, interesting, looks promising”
