Slashdot Mirror
Does Italian Demo Show Cold Fusion, or Snake Oil?
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.
Wired's article is remarkably optimistic.
Parts of it, yes. But I think the article does an okay job of keeping cautious. Maybe you read only the sentences you want to? Allow me to cherry pick a few:
Rossi's heavyweight supporters include 1973 physics Nobel prize winner Brian Josephson. Josephson also supports telepathy research.
Skeptics point to the lack of published science, and the way that Rossi keeps details of his special catalyst secret. They also point to his past involvement in Petroldragon, a company involved in converting organic waste into fuel, which collapsed in the 1990's amidst allegations of dumping toxic waste. (Rossi maintains that he was the victim in this complex case).
Until August of this year, Rossi was planning his big launch in Greece, and an E-Cat factory was being built in Xanthi. But the deal has somehow fallen through for unexplained reasons, vaguely blamed on pressure from "international energy interests" who may be threatened by the invention.
"According to my analysis, his claim has no scientific credibility," Krivit told Wired.co.uk. The device he claimed to heat a factory in Bondeno seems to exist only on paper."
At this point, I'm calling it 'tabloid science journalism.' This guy is looking to get rich quick not contribute to human knowledge so I'm not paying attention to him just yet. Hopefully I get to backpedal in a couple months when he starts shipping but ... well, I'm betting there will be some 'delay' imposed by 'ominous forces' as Rossi's wallet fattens.
My work here is dung.
Most of the world operates on first-to-file, not first-to-invent. If you had a working "secret sauce", how insane would you have to be to not file a zillion patents on it? Protecting such inventions is exactly what the patent system is actually for.
If you were blocking sigs, you wouldn't have to read this.
I bet you $200 it's not cold fusion, or any other kind of new physics.
Why doesn't the gene pool have a life guard?
Nickel has the highest binding energy of any nucleus. When stars die it is because they've turned every element into iron and nickel and it is impossible to fuse anything further exothermically. Heavier elements, including copper, can only be produced in supernovas and they take excess energy to make. How could you get energy out of changing nickel to copper if copper has a lower binding energy? You can't. This process, like most free energy scams, defies the conservation of energy at a fundamental level.
You really find a lack of skepticism about global warming out there? Rather, despite more skepticism than about any other topic in current science, 98% of scientists with expertise in the field conclude that anthropogenic global warming is a major threat to our species.
Sometime you might try skepticism about skepticism. What's good for the goose is good for the gander. A skepticism that's promoted by a PR firm working for the oil companies, that previously promoted skepticism about tobacco and cancer on behalf of the tobacco companies, is a good target for skepticism about skepticism. Or do you believe that loading up the lungs with tobacco is health, too, just as you apparently believe that loading up the atmosphere with CO2 is benign?

The process is Ni powder + hydrogen gas + heat + pressure + (mystery processes/catalysts) = excess heat and transmutation of Nickel to copper. Water is not involved in the process.
I think the big question on everyone's mind is if this actually *is* a nuclear reaction. There could be some sort of chemical reaction going on with the hydrogen, causing it to give off heat. If so, this 'reactor' is just another hydrogen fuel cell (possibly more efficient, maybe not). Not that a fuel cell which can be made using a "cheap catalyst" would be a bad thing - Slashdot has had a number of stories of people working towards such. But, fuel cells are not an energy "source", in the same way as an alkaline battery is not an energy source - but it could be a very convenient storage mechanism.
The bigger problem is that Ni62 is the most tightly bound nucleus known, http://hyperphysics.phy-astr.gsu.edu/hbase/nucene/nucbin2.html#c1 or http://www.nndc.bnl.gov/chart/ Fusion or fission of Ni62 require an input of energy; they clearly aren't measuring spontaneous release of energy in a fusion event...
About a month ago I got an email from my dad in which he asked my opinion on this issue, since I have a PhD in engineering and work as a researcher. The case had been presented to the public in a Italian TV magazine. I drafted a debunking on various grounds, which for your benefit I report here.
Short version: this Rossi guy is a convicted felon, his buddy Focardi an old, crooked professor with no relevant publications since the 60s, and they are after the money of naive investors.
Detailed version:
Mr. Rossi is therefore only looking for rich, greedy fools that will pump money in his next bankruptcy fraud. As a consequence of a certain prime minister and his modifications to the legal system, crimes like bankruptcy fraud are now very difficult to prosecute in Italy, so Rossi could just get away with it this time.
