Engineers devise invisibility shield
We're one step closer.
However:
[quote="From the article"]Pendry warns, however, that the concept as it stands is "no magic cloak", because it would have to be delicately tuned to suit each different object it hides. Perhaps even more of a drawback, he points out, is the fact that a particular shield only works for one specific wavelength of light.
An object might be made invisible in red light, say, but not in multiwavelength daylight.
And crucially, the effect only works when the wavelength of the light being scattered is roughly the same size as the object. So shielding from visible light would be possible only for microscopic objects]

The technology my children are going to see, and especially my childrens children is going to be amazing. I bet by then they will be able to fully cloak, since the technology is already here its just got to be fully developed. Just a matter of time before there will be full AI machines in the Army, Navy, etc. too.

so what does that mean, invisible hidden cameras now everywhere?
privacy is gonna go out the window

you have nothing to worry about.

the technology will evolve of course
this is just the first iteration
the time will come

or kewl lightsabers =) oooo lightsabers..... *edit* and maybe some kinda "force" =P oooo force....wee96 wrote:The technology my children are going to see, and especially my childrens children is going to be amazing.
