"There are no regulations in Florida or anywhere else pertaining to cold nuclear fusion reactors, because most scientists do not think they exist. If there were a 1-MW nuclear fusion reactor, the authorities would have no regulations governing it, but that does not mean they would allow it to operate. If they found out about it, I am sure they would close it down, and probably cordon off the neighborhood with dozens of police cars."
It doesn't matter whether ithe device is nuclear, zero point energy, or millions of Maxwell's Demons dancing on a stage...the important meme here is "experimental". Prototype devices being tested for industrial applications are simply not regulated to the same stringency as devices being sold commercially. They are in a different category. I know this from twenty years of experience working with such systems. Admittedly, my experience is largely in Louisiana and Texas, both of which have far more industry of this sort than Florida, but I would think that would mean that such regulations would be more comprehensive rather than less. Instead of repeatedly regurgitating the same silly comments, just point me to the section of Florida's regulations that apply.
