Future of Fusion Energy

What Hacker News says

   Triple product (efficiency ) has increased faster than moors law for the last 50 years.

   Still people make jokes about fusion research, some things just take time.

   I recommend this excellent review of the even more excellent book „The future of fusion energy“

   Yep.

   It's a well done article that had a lot of research behind it.

   FWIW if you're interested in Fusion the book 'The Future of Fusion Energy' is very good.

   Also Commonwealth Fusion Systems put out a lot of interesting stuff about how they are going. Even having a look at their YouTube channel is worthwhile.

   Metaculus has a lot of stuff on predictions about when fusion will be made viable :

   This is an excellent interview.

   For anyone looking for more MIT's Zach Hartwig lecture on why fusion is moving now and why CFS is taking the approach it is this lecture is excellent.

   The book 'The Future of Fusion Energy' is also really good.

   Yes, but the really hot part is not emitting visible light. ;)

   If you're curious about why the bottom glows: ExB drift pushes electrons to the bottom. I'm sure that doesn't make sense, but unfortunately there isn't really a shortcut to understanding here. Some books are pretty accessible though (I'm a fan of The Future of Fusion Energy).

   And, of course, there is always the freely available IAEA textbook:

   I have a question, i ve read a book recommended on here, about fusion, called the "The Future of Fusion Energy". (It was very good, can recommend for a general topic overview and history of progress).

   But i do not understand the general approach to plasma-vessel construction, in particular, why it is so passive. Its either "bend" to orbital shape dicated by the plasma physics properties when constructing (Wendelstein, Stellerators etc.).

   Or increase the containment vessels magnetic field strength (scaling up the reactor, high-temperature-superconductors) until it is capable to hold all the chaotic increasing fluctuation inside no matter what.

   My Question: Is there not a more active, not brute force approach for containing the plasma? Sort of "Whack-The-mole" countering the escape-events as they happen in a Tokamak?

   If i understood correctly, the system adds to itself constantly energy (its a reactor after all) and any chaotic butterfly wing flapping on the plasma current can shape up to a tornado breaching the containment and ending fusion.

   For anyone interested in the current state of the art of plasma physics and fusion technology I strongly recommend the book "The Future of Fusion Energy" by Jason Parisi and Justin Ball.[1]
