    Good find Shaz!

    Klingon technology today! I'll wear it in my invisible boat-mobile.

    A few downsides: Tachyon Emissions can still give your position away. And what if the batteries go dead and you become visible again? Better be wearing something decent under the cloak.

    They're talking about materials that would conduct light around, like a cylindrical shield. The main problem is that no light would go through the shield - you'd be in the dark, unable to see out!

    Well, considering the way that my car is ignored on the freeway, other drivers acting as though I were not there, I have frequently suspected that my car either suffers from periods of invisibility or Harry Potters Cloak has be draped over it. I am absolutely certain that upon entering a parking lot, my car becomes totally invisible to drivers and pedestrians, especially pededstrians!! Now and then I have parked and checked my car for a sign reading "Hit Me"! but by the time I look, someone has removed it.

    Wow, it seems as though someone else has already developed this beyond theory... Check it out! http://news.bbc.co.uk/2/hi/asia-pacific/2777111.stm

    While this looks pretty cool, it's hardly anything like the Harry Potter invisibility cloak, and the way it works probably has no practical applications for coats: "The image from the camera is then projected onto the coat, so that the wearer appears virtually transparent when seen through a viewfinder." I found a pic of the way it works on howstuffworks.com ( http://science.howstuffworks.com/invisibility-cloak.htm ):


    And this is simpler and different from the theories mentioned in the first article: "Pendry and his co-authors also propose using metamaterials because they can be tuned to bend electromagnetic radiation -- radio waves and visible light, for example -- in any direction."

    Anyway... neat stuff!!

    Unfortunately, I don't see HP nice fantasy story around...

    Just the dark shadow of advanced sthealt weapons systems and warcraft.

    Microwaves...humm...like radars emissions....invisibility...hummm...nice way to approach the ennemies....
