The question is about a specific experiment. The reason for closure is that this is about an unpublished theory.
In its current form (v1), the question in its entirety is
Regarding the recent superconductivity claims video
Can anybody please tell why this cannot be electrostatic repulsion?
This question is not self-contained. It cannot be answered without following the link. The link goes to a website that I'm not familiar with, and I haven't clicked it; it could go to a well-written paragraph, or a technical paper, or to a three-hour video by a raving lunatic, or (worst) to a short video.
To make the question on-topic, one step will be to make the question self-contained, so that an interested person can gather enough evidence to answer the question without necessarily leaving our site.
I don't know why two of your three close voters chose "non-mainstream" rather than "unclear" for their close reason. Note that part of our "non-mainstream" close reason is that we don't peer-review unpublished material here; perhaps the applicability of that reason would be obvious if I had clicked on your link.
