The Photonic Thermos arrives, researchers stated that an ordinary thermos insulator could not block the warm inside and become cool in an hour of stacking. But last year the researchers discovered the essence of the photonic crystal which can block a single heat flow even more effective. In this present year in October Physical Review B a presentation had been revealed this unexpected ability of this structural device. The researchers thought that their work can be astonishing applications in the field of communications and computerization that either one day they can used this kind of thermal legacy, what's more if this device can turn the sun's heat into an usable kind of energy.
