Synthetic crystal insulation that reflects heat!Â Wow this is a good one!
Deep-space probes and scientific devices in Antarctica could soon get a new form of insulation based on synthetic crystals that stop and reflect heat. Such material could eventually lead to the best insulation ever created, even at room temperatures.
The crystals work by manipulating phonons, or vibrational waves that can carry either sound or heat depending on the frequency. Each crystal structure consists of alternating layers of silicon dioxide and a polymer material, so that the spacing between similar layers matches the wavelength of phonons. That allows the material to block and reflect back the phonons in the form of heat.
