I hadn't realized that was a different kind of record (150M degrees for over 1000 seconds). I suppose the ions have more mass than the electrons so that temperature is harder to maintain, but I have no idea about the physics of having them not heat up at the same rate.

BTW I had to vouch for your comment to reply because you have a history of making short and sometimes brusque comments and HN has punished you for it. If you would make slightly longer comments in the future more people will engage with you and it will be more fun for you.
