The "plasma-powered flying saucer" in your article doesn't appear to have any relationship to the thruster in the original post other than the word "plasma". The former appears to be an air ionizer [0]; the latter is a repurposed fusion research tokamak.

This is analogous to referring to both bumblebees and the Saturn V rocket as "liquid-powered flying vehicles".
