It is nothing to boggle about. Standard sort of thing: Tinkerer makes a claim, usually pretty outlandish and impossible. People look into it. Happens all the time. Usually find that the experiment producing the anomaly is defective in someway.

[OBAFGKM]

Tinkerer makes a claim, usually pretty outlandish and impossible.

Turns out there really are theoretic bases for this phenomenon, and, although Podkletnov is apparently difficult to work with, his observations really should be taken seriously. For example:
