I like Tesla too, but dude, this sounds like the Chinese water torture cell that felled Houdini. Sometimes the greatest finally go too far. Being protected by a Faraday cage, this stunt is unlikely to kill him, but the affect upon the brain would appear to be unknown. Part of me says it is a great experiment, the other part of me says, dude, that is what lab rats are for, lol.
At any rate, as AC/DC says, "For those about to rock, we salute you." :-)
