Nuclear Fusion Progress

Comments focus on recent nuclear fusion breakthroughs, skepticism about timelines for practical energy production (e.g., 'always 50 years away'), and questions about viability compared to past experiments.

Do you think we'll crack fusion?

Maybe closer to energy positive fusion?

"Fusion is always 50 years away" for a reasonhttps://www.reddit.com/r/Futurology/comments/5gi9yh/fusion_i...

Does this mean we are only 10 years away from fusion?

Nuclear fusion has entered the chat.

Can someone ELI5 why this is significant over previous fusion experiments?

Fusion has made leaps recently and is no longer looking as unviable as you suggest.

It's clearly about fusion. Maybe you meant it's not about generating power?

Hacker News + science is often a very bad mix. Any evidence this is actually a fusion device, not a chemical energy converter or a brick?

Fusion used to be perpetually 30 years away. We’re making progress!
