An anonymous reader writes "Today, Wired.co.uk is running a story, 'Cold fusion rears its head as "E-Cat" research promises to change the world.' It gives an overview of the technology that claims to fuse hydrogen and nickel into copper, with no radioactive by-products, to produce copious amounts of heat, inexpensively, with a 1 megawatt plant scheduled to come on line later this month. Apparently, Wired was not aware that today is a big test in Italy by scientists from around the world, who will be observing the technology in operation, including self-looped mode. A real-time update page has been set up at PESWiki, which has been a primary news provider of this technology since it was announced last January." Wired's article is remarkably optimistic. I'd love for this to be true, but many decades of scientific-looking free-energy machine scams make it hard to be other than cynical; the claim of a secret catalyst which "can be produced at low cost," controlled-access for outside observers, the lack of published science to explain the claimed effect, and skepticism even from the free-energy world — along with a raft of pro-E-Cat websites registered anonymously earlier this year — all make it sound like this follows the marketing style of previous "over unity" / perpetual motion machines. I invite Andrea Rossi to take part in a Slashdot interview, if he's willing to answer readers' questions about his claims.
