Based on watching videos and reading about other stuff he&#x27;s done:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Andrea_Rossi_%28entrepreneur%29" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Andrea_Rossi_%28entrepreneur%2...</a><p>I vote for this being a scam. A very clever scam but another scam.<p>There is in fact whole cottage industry centered around energy and battery technology. The audience for this is not us or other scientists but investors. It is about demos, videos, secrets, lots of tubes and wires, flickering lights, acting like they just discovered free energy and will revolutionize the world of physics. The goal is to make people with money believe you.<p>In general, just because people have money doesn&#x27;t mean they also know science and thus many are targets of scam artists. But the &quot;art&quot; part in scam art is to also pick an area that is not too confusing (brain surgery, genetics, something too theoretical, etc) or too hard but something seemingly simple -- &quot;we make energy&quot;, &quot;we have a new battery&quot;,  &quot;a device that produces more energy than it consumes&quot; etc.
