Not for a correctly performed independent test, anyway. However, Celani, as a physicist, should know that magnets do not store or make appreciable amounts of energy and in any case, no usable energy at all. I suppose it might be fun to test the kludge in a smaller version if it were ever to be provided but it would be a waste of time in any case. Also a supposition: Celani knew the "inventors" would never comply with a correctly designed test.
Certainly he knows about magnet motors as you say. My guess is he went there for the free food, and out of gratitude offered to test a small unit.
