By the time the coherent radiation (needed to make an image) passes
Were not talking holograms, Jimmy-boy
It is fun isn't it? I think what he was trying to convey were the effects of reflection, absortion and diffusion. Without having tried one of these devices or knowing what wavelengths they use or the characteristics of building materials at these wavelengths all I have is a gut feeling that says you'll get not so much images as locations. He's probably right about the windows being the primary vulnerability. Next time I'm at Home Debit I'm going to see if they sell more kraft paper or foil-faced insulation. Seems to me the foil is less common than it used to be. Is this a new conspiracy? Fibreglass-AG? So, if you're expecting to be raided and you don't want the fuggers to know where you are, keep the house at about 95. That should help. For about 15 seconds. If you have an illicit heat source insulate it, cool it with water and dump the heat down the drain or on the yard. Mike
