'Invisibility cloak' that could hide tanks and troops looks closer to reality

Harry Potter’s ‘invisibility cloak’ appears closer to reality as Canadian camouflage manufacturer Hyperstealth Biotechnology has applied for patents on its ‘Quantum Stealth’ material.

The ‘inexpensive and paper-thin’ technology works by bending light around a target to either alter its position or make it vanish altogether, leaving only the background visible. It is touted to be able to obscure the positions of heavy artillery, ground troops or even entire buildings from certain viewpoints.
