Cheap clean electrical power from fusion has been a dream for decades. Billions of dollars have been spent on fusion experiments.
There’s a rather dark joke about commercial fusion reactors: In the 1990s they were two decades away and today they’re two decades away. Fusion is always two decades away.
This post doesn’t mention the fact that energy generation for fusion requires a breakeven reaction that produces at least as much energy as is put into the reaction. The quote “ the containment system works as planned” means nothing. The article linked to in this post states:
This is a significant step forward in stellarator research, since it shows that the complicated and delicate magnetic topology can be created and verified with the required accuracy.
What this means is that they people working on the Stellarator believe that it was a successful experiment. This may lend credence to the claim that the Stellarator approach is more promising than the Tokamac approach. But I’m sure that this is controversial and something that the people working on Tokamac fusion disagree with. Neither approach has lead to anything like a working fusion reactor.
Nuclear fusion is the long standing dream of power generation. A working nuclear fusion reactor would mean power generation without greenhouse gas emissions or significant nuclear waste. Realizing the dream of a fusion reactor is still two decades away.
