we should stress that they still dont know exactly whats going on inside the sealed steel cylinder reactor.
While Rossi hasnt provided much in the way of details hes a very secretive man...
In NASAs tests, it takes a lot more energy to fuse the nickel and hydrogen than is produced by the reaction. Rossi, it would seem, has discovered a secret sauce that significantly reduces the amount of energy required to start the reaction. As for what the secret sauce is, no one knows
Science by hiding secrets isn't science. It is, however, a common trait for quackery. "I've got this secret formula to make this thingamabob do this thingamajig, but it's secret and I'm not going to tell you what it is. But if you help fund my research you'll be in on the ground floor of something really big."
Of course, the article you cite ends like this:
If Rossi and Focardis cold fusion technology turns out to be real if the E-Cat really has 10,000 times the energy density and 1,000 times the power density of gasoline then the world will change, very, very quickly. Stay tuned; well let you know when or if the E-Cat passes peer review.
Bingo! No peer review yet. And we know what peer review did for Pons and Fleischman.
I'll stand by my post. Cold fusion kooks!
