I will remain skeptical until it is independently reproduced and verified and gets demonstrated at scale.

I would love for this to be real, but until it is verified I remain skeptical. To quote Sagan, "extraordinary claims require extraordinary evidence".
It might be too expensive to scale this up such that it generates an appreciable amount of power. It might require mass-production techniques.
Regarding the attack on scientific journals which tend to ignore anomalous results, I agree that it's a deeply flawed system (even if we are to forget about parasites like Elsevier & co), but there is no simple solution to that. Journals are incentivized to cultivate their reputation by producing a constant stream of good enough papers. Accepting papers with extraordinary claims is a bad strategy from risk-benefit point of view. On every paper which indeed correctly points at a future breakthrough you get many-many thousands of "duds".
With the advent of preprint sites at least you can freely share your results. Hopefully, eventually we will build an open reputation system on top of them, which will replace the existing system of journals and conferences.
I wonder what it would take in terms of expense/equipment to do an independent verification.
I do suspect this is just another EMDrive. Interacting with the vacuum to shift energy around is well-known (again, see Hawking radiation [1]), but holding on to it overall for long enough to violate the uncertainty principle (the one for the E-t commutator [2]) doesn't work. And I don't think you can hold it just long enough to reverse entropy... though that doesn't sound prima facie impossible. Making a measurement incorrectly, though... I do that every day I'm in the lab.
Addition: Also, the MDPI journals are kinda-sorta just one step up from trash-tier, at least in my mind, so I don't pay much attention to work that can only manage to get in to one of them.

However, I do not know how reputable that particular journal is.
Sounds like a good quantum analogue of Maxwell’s demon!
That said, nothing I saw in the paper suggested it would be expensive to reproduce this effect. The palladium is pricey but you don't apparently need very much and the fabrication, as described, it pretty standard semiconductor fabrication steps. Feature size is pretty large compared to modern processes so you wouldn't need a state of the art fab to make a wafer of these things.
Since am not a physicist myself I could well be proven wrong tho. In that case this reply gotta end up infamous!
