Another take from wikipedia: "In 1999, the Nobel prize winning physicist Philip Warren Anderson said he is "sure that it's a fraud",[12] and in the same year another Nobel prize winning physicist, Steven Chu, called it "extremely unlikely".[23] The following year, a 2000 patent based on its hydrino-related technology[24][25] was later withdrawn by the United States Patent and Trademark Office (USPTO) due to contradictions with known physics laws and other concerns about the viability of the described processes, citing Park and others.[26]"

Wikipedia has a strong skeptical bias - just read the talk page. The article is more than a decade out of date but is basically frozen by the moderators. Look at the videos on their site to see the progress they have made in solving the engineering problems - mainly the apparatus melting from the excess heat. This is the breakthrough physics has needed for 50 years or more - ever since quantum mechanics took a wrong turn in the 1930s.
