Instead, silence.
I consider it very unlikely that the experiment was a success. So that leave two possibilities: 1). Deliberate fraud, a la Madoff. Or 2). interesting science, not fusion, but still a reaction that is not well understood. Something like a fuel cell, when for a while it looks like e_out > e_in, but in reality e_in happened over a long time, and as such the reaction is non-sustainable.
I'm hoping for 2)- an honest mistake in which we learn something.
No serious journalist would touch this without a ton of caveats, and then what's the point? So a lack of massive mainstream media coverage doesn't really mean all that much.
Especially given that these guys seems to be secretive, which is understandable whether or not it's real or a scam - if the process is easy to reproduce, and claims are that the process is very simple, and thus if the effect is real they're probably worried about someone copying it and finding simple ways around any patents they might apply for.
Of course the second reason to be secretive would be if it blatantly is a scam or they have failed to make it work and refuse to accept that they won't find a way to fix it.
And history is littered by companies like this that claimed to have similar stuff for all kinds of reason and then just fell off the radar after it turned out they were frauds, wrong or delusional...
It is worth noting that the Italian Patent Office first rejected Rossi's patent on claims it was dubious, but they finally recently granted it in April 6, 2011: http://www.uibm.gov.it/uibm/dati/Avanzata.aspx?load=info_lis...
As I said, Rossi and Focardi are very bad at making themselves look credible. Hopefully, over the next year or so, the situation will clear up.
Let's just say that I did enough research that I am now convinced that the E-Cat device is not only possible, but likely very real. Read everything, especially the site of Christopher Calder that I submitted as another entry because it is worth it: http://news.ycombinator.com/item?id=3176820
