Cloaking Technology Advances Made, Spock Nervous
Though military application is obvious and probably one of the more well funded efforts with the research that is being conducted, there are numerous usage models that can be realized with this emerging technology.
"By eliminating the effects of obstructions, cloaking devices could improve wireless communications, or acoustic cloaks could serve as protective shields, preventing the penetration of vibrations, sound or seismic waves."
Seen here is Duke University's David R. Smith with a new prototype of cloaking material that is said to have the capability of cloaking a "nearly limitless" range of waves including visible light. And you thought those camouflage pants were cool. Just think what you could do with a cloak suit. Wait, actually, don't go there.
