The difference though is that F&P were real scientists who simply happened to be wrong. They published their work in a way that could be replicated, and those experiments found their results were in error. They were shamed and embarassed, but they played by the rules and were doing real science.
This nonsense is pure charlatanry and fraud. An "inventor" working alone and discovering new fundamental physics without published results or peer review needs to be viewed far more suspiciously.
