Re: Dematerialised over the shark ?
The thing that bothered me about the glasses, is that they continued to work in the Faraday cage.
Why shouldn't they? A Faraday cage electrically isolates the inside from the outside, an electronic item will work as well inside as outside if it is self-contained and does not need any signals from external systems.
If electrical systems failed inside a Faraday cage them people would die on entry as life is basically an electrical system.
EDIT: If he was broadcasting WiFi or similar from inside the cage then that is silly and would plainly not work.
