The sad thing is, it's not too hard or too expensive to build a
fusor to experimentally verify that fusion reactions do occur; it is well within hobbyist capabilities – and if you have $20k/20k€ or so, you can buy it (in components) straight off the shelf.
Z-pinch increases plasma density and confinement by inducing a current into the plasma, which due to Lorentz force (the current generating a magnetic field that) pinches the plasma closer together, and that costs much more.
Tokamaks require costly superconducting magnets (to get the magnetic field strengths necessary), and unless you intend to run it for only a short time, you need something like tungsten (wolfram) plating on the inside to deal with the high-energy particles; stainless steel becomes very brittle rather quickly in that onslaught.
Showing a picture of what the magnetic fields or electrostatic fields in such experiments are, does not indicate any kind of understanding. It is just repeating something you've seen, without understanding what it is; just like a Lyre bird repeats sounds it has heard in its mating songs, with gusto.
"Frequency", "helix", and "density" are terms that seem to be in vogue among those who think every physics experiment before them has been done wrong, and they know better because healing crystals.
Dammit, this physics stuff is not just talk and theory, it is something that is already done experimentally. And not just by scientists; hobbyists have built several fusors too. Dismissing all that effort is like dismissing an oncoming train: you do it at your own risk, and you're damn likely to be squished, with onlookers quipping that that was particularly stupid.
High-school level of "electrons rotate around atomic nuclei" physics won't cut it, because fusion is deep within nuclear force ranges, in the quantum realm. Decades ago, early in my physics uni studies I started with Introduction to the Structure of Matter by Brehm and Mullin, and while it is a steep learning curve, I really enjoyed it. Something of that sort is needed to grasp the models that have been experimentally verified already.
Precise math, or at least crude approximations with the most significant terms, is your initial tool; just like
dimensional analysis is in applied physics and engineering. Adjectives
feel powerful, but they don't really describe much; the human brain is prone to
magical thinking, and if you don't nail down your ideas with hard math, it is all just a smokescreen your own brain is putting forward. I know from long experience that when I have an idea, I must nail it down in math and/or software code,
and experimentally verify it works, because my mind too often thinks it knows something when it doesn't, and occasionally convinces and hoodwinks me too.
And if anyone thinks I'm putting others down or trying to show they're bad at physics, think again. I'm trying to show that those interested in this stuff can certainly
learn, and where to start. Making errors is perfectly okay; it's not acknowledging and not fixing them that is stupid. The questions I posed earlier are not something I copied off somewhere else; they are things I myself had to learn the hard way, spending who knows how many hours while doing so... and my point is, if
I, Nominal Animal the Verbose Uncle Bumblefuck can do it, so can anyone else with sufficient time and effort.
If you think you might have a new idea, go ahead and explore it! But, do not look for
support of your idea, look for the most detailed criticism and involved examination you can find, even though it can feel crushing to have the fatal error in ones idea pointed out.. but that's how we learn. Use math as a tool, because it really is the best tool we have for this. Consider top athletes: do they look forward to winning against developmentally challenged competitors, or to pitch themselves against the best competitors around? And why?
Having other like-minded people support your idea
feels nice, but having them show the holes or misdesign is worth much more. When I post one of my schematics or boards here, I'm looking for advice on making it better, and especially about any pitfalls I might have dug for myself that experienced people can detect in my plans. I value that sort of critical but useful help more than I value my personal feelings. Those trying to develop their own ideas should consider the same approach.
