Thanks Gary, I am not an expert. I popularize, but I do try to listen to actual experts and make corrections.

Sometimes that is part of the interesting journey of writing. You write something and you get responses from people who can point out mistakes you made and you learn something.

But if somebody just says "you are wrong," then of course there is not much to learn either for the author or for other non-expert readers.

Sometimes the most interesting information can pop up in the comment fields. I have learn a lot from following discussions on e.g. Hackers News in relation to various technical subjects.

Since you have followed fusion for some years, do you have any thoughts on what approach looks most promosing? I see so many strange approaches today which did not exist when I first began reading about fusion in the 80s. Back then I think it was pretty much limited to Tokamak reactors with magnets and laser fusion.
