I was wondering how one would transmit image/video feed from inside to outside in realtime? Any hole to transmit the feed is gonna be a no-no(radiation leakage). Basically, if there is path for some EM communication from inside to outside, then MW radiation will also leak along that path(unless the path has some sort of band pass characteristics). You could do some kind of time slotted transmission(In one slot, close the communication hole to make a perfect metal box, turn on microwave. In next slot, turn off microwave, open hole and transmit video feed. Make the time slot ~msec for near real time feed).

With some kick ass marketing it should be possible to get the message to people - 1000x reduction in radiation!(?) why take the remote chance of effects of radiation!!

Interesting....
