The idea for the invisible blanket emerged from experiments conducted by MIT researchers. To create an invisible blanket made of Carbon nanotubes (which conduct heat), they used a transformation method. They created an infinitely thin surface that appears as another silver rooftop from the sky. Visitors under the canopy are hidden from view, while the surrounding city is filtered through its golden underside.
Quantum cloak
A quantum cloak allows an object to be hidden from the observer. The conformal mapping process where the mass parameters of a particle transform to isotropic state by applying an external force creates a quantum cover. This force, also called the electric power, is well-known.
A quantum cloak could be useful for military use. Through its unique combination light-bending nanotechnology fabric, it can hide an object. This kind of cloak is already being tested on soldiers and marines to give them cover against sniper attacks.
Transformation design method allows for invisibility cloak
You can model the invisibility blanket using the transformation design method. The transformation method considers the physical properties of a material to be the basis of the design. The radial index and azimuthal components determine the cloak's characteristics. These components are shifted from zero to one at both the outer and inner borders of the cloak.
By considering the physical properties of the material, the authors devised a cloak which can be invisible using ultrasonic wave technology. The number of parameters needed to achieve invisibleness was reduced by the authors. This preserves the invisible effect and preserves effective refractive.
Carbon nanotubes conduct heat
Carbon nanotubes consist of extremely thin sheets made from carbon and can conduct heat very effectively. The scientists who studied the carbon in the nanotubes found that they can reach temperatures of 2,800 kelvins without burning the carbon. This is more than twice the amount of heat that is generated in the average fire.
These nanotubes come in single-wall, dual-wall and multi-wall versions. To visualize the single wall version, wrap a graphite sheet one-atom thick around a circular. The double-wall version, on the other hand, is more complicated and has a gap in between the conduction and valance bands.
