Actually in the case of Rossi there have been several very telling instances that reek of, at the very least, bait and switch tactics if not outright fraud.
For example during the runup test for the 1 megawatt power plant which only ever produced about 500 kilowatts worth of heat at any given time it was
connected directly to a constantly running 500 kilowatt diesel generator....
This has been covered in quite a bit of detail elsewhere. But suffice it to say that Rossi is at the best a horrible businessman with no understanding
of how to market a new and viable technology. At the worst he's an outright con man. Judging from his past performances with petrodragon and his
thermoelectric devices that he got millions from the DOE to develop and never delivered on I'm leanin towards fraud.
Now this is not to say that companies like brillouin energy might not actually be on to something in the cold fusion arena. But Rossi is one hell of a
bad example to use.
I remain cautiously skeptical about the quentron situation. Phillip Hardcastle has been working for years towards building these devices, and is
apparently working with a major university to bring the devices to fruition. We will just have to see if the November release date goes any better
than the two previous release dates he has not kept to.
