I find it very hard to believe in anything published originally by Futurism... can someone with more background on the topic comment if it's trustworthy stuff?

- tigershark 9y agoNo idea about futurism, but someone that speaking about nuclear fusion writes something like this is not worth of any consideration: Not only does the fusion process expose reactors to extreme pressure and temperatures Seriously? Extreme pressures in a tokamak? What am I missing?
- Jedd 9y ago> Seriously? Extreme pressures in a tokamak? What am I missing? Maybe they're including stellarators, and other possible variations -- as the article didn't specify tokamaks.
- mirimir 9y agoYes, that surprised me too. Are there any fusion designs without high vacuum? But on the other hand, magnetic stresses in full-scale systems would be huge, right? And one could consider that to be pressure. In that it reflects confinement of the plasma. Or it could be an incoherent edit.
- tempestn 9y agoTechnically a high vacuum is an extreme pressure, just a negative extreme.
- mirimir 9y agoSure, but isn't 1 atmosphere pretty small?
- DennisP 9y agoSeveral years ago I got a tour of MIT's Alcator C-Mod, which had the strongest magnetic fields of any tokamak in the world. A grad student showed us a metal tie, about a meter long and several inches thick. He said they'd calculated that two of them could hold down the Space Shuttle when it was trying to launch. Holding the C-Mod together at full power required 38 of them.
