Seconded. This is fascinating stuff and reminds me of some crazy rant some guy was telling me about anti-gravity and how electromagnetic “ribbons” could propel you. Obviously the guy was nuts, right? How would one go about learning more about electromagnetic plasma containment folding?

Haha, no I am just some random guy who reads too many Wikipedia articles. "Electromagnetic plasma containment folding" does sound like something a crazy person at a bus station would rant about. My explanation was definitely over simplified, but I'm not knowledgable enough to go into detail on the topic. I can't even point you towards something to read on the topic since everything I read about it is like 15 years old at this point.

    My favourite fact about it comes from https://phys.org/news/2016-02-plasma-physicist-discusses-wendelstein-x.amp https://phys.org/news/2016-02-plasma-physicist-discusses-wen... “…the supporting structure can only withstand the forces if the interfaces between the ten individual segments of the central rings, which weighs several tonnes, are built with a level of precision of less than 100 millionths of a metre…” - and they found a small family business in the north of Italy capable of doing this!

      Odd units. 1 meter = 100 cm = 1000mm. So 1 millionth of a meter = 1/1000th of 1mm. thus, 100 millionths of a meter = 0.1mm, or ~4 thou in American units. Easily achievable by hobbyists, let alone by serious, professional equipment. Sure, that is a pretty exacting specification for what I suppose is a big machine, but I'm pretty sure very normal things like say, car engines get made to far tighter tolerances.

        You messed up at your last step 1 millionth = 1mm, 10 millionth = 0.1mm, 100 millionth = 0.01mm 0.01mm is very difficult when you’re talking large custom objects with complex shapes.
        dale_glass 3y ago
        Oh, English fail on my part then. I had assumed that 100 millionths of a metre == 100 * 1/1000000.

        The german site of the source speaks of 0.1mm so you were correct > bei Toleranzen von teilweise nur 0,1 Millimeter https://www.ipp.mpg.de/de/aktuelles/presse/pi/2020/01_20 https://www.ipp.mpg.de/de/aktuelles/presse/pi/2020/01_20

        No your correct, I just read it wrong. Really needed to pay attention to the s.

        I think the original commenter is right- correct me if I missed what you’re getting at. Keeping it all in the same units until the end here: 1 millionth of 1 meter = (1 / 1,000,000)m = (1e-6m) 1 millionth * 100 = 100 millionths => (1e-6m) * 100 = (1e-4m) = 100 millionths (1e-4m) = .0001m | 1m = 1000mm => .0001m*1000 = .1mm

        Ops, 100 ( 1 millionths of a meter) is a much more reasonable tolerance here than 1 / (100 millionth) of a meter. I am to used to people saying 100 millionth of a meter to mean 10 nm or 0.01 µm which would have looked insane if I had written that. Aka 100 millionth vs 100 millionths

  I just read a bunch of stuff about her from her son. About how he took care of her in her advanced years and her alzheimer's disease. Sad but also peculiar about her DoD work and how she "never talked about it". I wonder what it was? trying to get an alien craft working again? developing anti-gravity weapon? a ship? a hoverboard? please say it was a hoverboard. Her claim that "You can take a bowling ball and place it and it will stay." is fascinating. I would love to see footage/video of this. Small electro marbles and globes are one thing, a bowling ball or other large non-magnetic object!? man oh man!
