    It's just a way PETA getting free advertisement, they know nothing is going to happen. Expect for a load of people to get wound up and share it all over the place making more people aware of Peta. Best bet as with most of these things is to ignore and move on. Otherwise ypu giving them what...

    Should a giant steel framed human aquarium be earth bonded?

    But the tank water I would hope have a chlorine or other water treatment in there. Which would massively increase its conductivity to better than that of human body. What does the tank sit upon? It may all ready inadvertently have a path to ground though the ground it's self.

    You'll need some form of regulator to drop the voltage which will have it's own power loss. So you won't quite get 12amps @5v

    New Build Home Media/Entertainment wiring plus future proofing design/advice!

    I would doubt you'll add any real long term valve to the property, compared to your initially investment in AV system.
