As already stated, no experiment will convince the babblers. only sufficient commercial sales to to remove all doubt.
The biggest problem with this statement is that it is utterly false. Skeptics (in Adrian’s special world view: babblers) have laid out the requirements for a convincing experiment literally hundreds of times. Rossi has never met a single one of them and without a doubt never will. As for commercial sales... as soon as flying pigs fill the skies.
