"End all involvement. This is a massive and pointless waste of money. It will never lead to any practical source of energy."
"I'm so glad you're smarter than all the scientists working on it."
Maybe he is, maybe he isn't. But he's still right.
There are two definitions of "working" one needs to consider. One is "this device fulfills a minimum technical requirement". The other is "this devices works, and is economically attractive". It is very clear to everyone involved, including "the scientists working on it", that ITER-like devices will almost certainly never fulfill the second of those two definitions.
I don't say this idly. I know some of the scientists working in fusion personally, I've written to and had conversations with a number of others. I've distilled the information down into the majority of the articles you'e read on the topic on the Wikipedia. I have a good overview level of the technology, and more critically, the other technologies fusion completes with. So I can speak with a good level of authority on this topic.
It's that (second) lash point that's important. If fusion were, as someone in this thread put it, "the only solution" to our energy problems, then the two definitions become one. As soon as it works, you start building them. But it's *not* the only form of energy that can solve "all our problems". And those solutions already work, and more importantly, will cost less than fusion of the ITER (or NIF) ever could. Period.
Even if ITER works, and even if there is a follow-on device that works better, there is, in theory, no way to make it cheap enough to compete with existing devices. For instance, on often sees the complaint that solar can't be the solution to our problems because the sun doesn't shine at night. Well actually it does, it just does it somewhere else. It will cost less to build enough panels to power everything AND a HVDC network to spread it around the world than it would to get the same power from fusion.
But don't take my word for it. Here's the word of *the guy that ran the US fusion program*:
First, we have to recognize that practical fusion power must measure up to or be superior to the competition in the electric power industry. Second, it is virtually certain that tokamak fusion as represented by ITER will not be practical.
