Andrea Rossi is by no means the only one who tries to benefit from people not understanding technology and science. We have several other technology scams going on, take Steorn Orbo or Blacklight Power, for example.
It’s nothing new, anyone remember the Great Oil Sniffer hoax of 1979? 
It has happened several times in Finland too! And amazingly, the fraudsters often go unpunished.
There was one case in Finland couple of years ago, that lead to conviction ( probation only). The “inventor” raised about million euros from private people to develop a new type of battery, that did not exist. He even seemed to have taken the idea for his invention from a famous Finnish novel and still managed to raise the money, and seemingly win a technology award by Frost&Sullivan .
However, he did not know financial law very well, so his emission turned out to be illegally arranged. In investigation, it turned out that he had used only couple of thousand euros for developing his nano-battery, while keeping the rest of the money for himself.
While the inventor of the amazing nano-battery got convicted , there have been other scams in Finland gone unpunished, because no litigant ever complaint.
One other Finnish guy raised several million euros from private investors. He claimed to have developed a theory of everything, and a new energy source of course. Wrote a book about it, called “We live in a black hole” and found a company. There where also quite famous, wealthy, and influential Finnish and Swedish people in the board of directors, amazingly enough 
His theory was far crazier  than any of the cold fusion/LENR nonsense, and still some people fell for it. And yes, he got away with it and the company’s web pages are long gone, thought the company itself seems to exist in some form. This happened in Finland just a couple of years ago.
Finland is a small country of just five million people, and even we have had several technology scams. Wonder how many scams are going on in the world right now?
It’s a strange planet and man is a strange animal.
