Even though the antilaser absorbs perfectly, it does so only at specific wavelengths of light, making it unsuitable for applications like solar panels that take in a broad range of wavelengths. (Other, specially engineered materials called metamaterials can perform those kinds of absorptions.) But because the antilaser can switch from absorbing to nonabsorbing just by changing the wavelength of the incoming light, it could prove useful in optical switches — for instance in futuristic computer boards that will use light instead of electrons.
Im thinking wireless transmission of energy....through space.
