back to article Secret of invisibility unravelled by US researchers

Scientists at the University of California in Berkeley have engineered a material that can bend visible light around objects. This development could soon result in technology that can render tanks, ships and troops invisible to the eye. Results of the US military-funded research are expected to appear in the scientific …

    . . . and the Russians just used a pencil

    Wouldn't it be easier to hide behind an LCD panel and stick a webcam up your arse?

    I was thinking of pointing the webcam behind you, but I think you may be on to something . . . . .

    Just upgraded camouflage

    Sounds like the main military application for this (assuming even that it does provide 100% invisibility in the visible spectrum) is as an upgrade to standard camo - something that makes you hard to see, provided the enemy isn't actively searching for you. Besides looking, there are (as pointed out already) far too many ways of detecting an invisible soldier: body heat, noise, radar/sonar, covering the ground with sand and looking for footprints, chucking paint/flour everywhere, using dogs/smellbots to pick up scent etc etc etc.

    Even so, it still beats green and black facepaint.

    Tolets seats at work are already made of this.

    As if the flush button.
