Assuming the Rossi gadget is real, neither he nor you have the slightest idea how it works or where the energy is coming from, so neither of you can offer any assurance that the machine is safe and that it will not go out of control and cause a catastrophe. On the contrary, Rossi has repeatedly claimed the machine irradiated him and made him sick. He is saying it isn't safe. Who are you to contradict him? You believe everything else he says, so why don't you believe this? If the machine made him sick it would be crazy to install it in a populated area. We have to first find out how strong the radiation is, and how to shield against it.
If it does not use radioactive materials, what makes it work? Why do you claim it is safer than a fission reactor when you have idea what makes it work? How the hell would you know?
That is purely hypothetical when applied to Rossi, but it is a real issue when applied to actual cold fusion device. It is an issue no one in this field has addressed -- or even thought about.
"On the contrary, Rossi has repeatedly claimed the machine irradiated him and made him sick."
NO! He, Rossi, said, that he opened up the shielding, observing the operating E-Cat and that caused him trouble.
"He is saying it isn't safe."
NO! He, Rossi, said, it is safe, because there is no radiation measured outside the shielding note to notice above background radiation.
"If it does not use radioactive materials, what makes it work?"
NO! He, Rossi, said, he does not use radioactive materials to make it work.
The WHY/WHO it works is his secret. And the work of his genious minions (military grade, of course), who are in his great team.
And this is of course a point for regulataions and to worry about by government/agencies.
Because this very well might be dangerous at runnaway points (I dunno know if it is the correct epression, it's my limted english language knowledge)
If is comes to the point of a claimed 40MW power installation at a claimed customer, controlled via HTTPS ( Mega LOL) and all problems arise of this claim (and maybe installation of devices) he sais, it will not be a single installation, but splitted ....
So, your above arguments will not be of any concern to the Mega-Babbler, aka AA.
