Here are two videos that do a great job of conveying the incredible accomplishment of building it. https://www.youtube.com/watch?v=u-fbBRAxJNk https://www.yout

  For a beginner, this was good followup material: https://en.wikipedia.org/wiki/Stellarator https://en.wikipedia.org/wiki/Stellarator

  How the hell do you test such a monstrosity? I mean... I know that testing complex software projects is a pain in the ass. But... this? I mean... how do you even begin to plan where all the wires and other elements go and then test that it's a sound design? I'm guessing they do a lot of simulations and such, but what if something fails? how much do you have to backtrack to fix a potential bug? It just boggles the mind. I had no idea these things were so complex. Thanks for the links. Edit: This video explains the elements quite in an understandable way [0] [0] https://www.youtube.com/watch?v=lyqt6u5_sHA https://www.youtube.com/watch?v=lyqt6u5_sHA

    > How the hell do you test such a monstrosity? That is very complex, and a large part of the design process is to make sure it actually is testable. The article actually describes the result of some of the system testing of the device. They have now measured the magnetic field and found that it reproduced what they predicted it should be.
