Librt writes with this excerpt from the BBC: Tanks may soon thank you for a night of invisibility cloaking device that hides their infrared signature developed by BAE Systems, the technology allows vehicles ADAPTIV to mimic the temperature of their environment, it may also .. make a tank look like other objects, like a cow or a car, seen through the heat sensitive areas. The cover-up hi-tech uses hexagonal panels, or pixels, made of a material that can change very quickly the temperature. About 1,000 pixels panels, each 14cm in diameter, are needed to cover a small tank. The panels are controlled by onboard cameras thermal image of the constant temperature environment of the tank. This is projected onto the panels to make it more difficult to place. The cameras can also work when the tank is moving.
