'Thermal cloak' hides objects from heat
http://www.bbc.co.uk/news/science-environment-17518210
The thermally cloaked region is shown in the centre of this heat map
The range of physical phenomena that scientists are trying to "cloak" objects from has a new entry - heat.
French researchers have shown how to apply the ideas of "optical cloaking" - the endeavour to make a Harry Potter-style cloak - to the thermal world.
The applications for the idea, outlined in Optics Express, stretch beyond hiding from thermal-imaging devices.
It could also be used to direct and move heat around in temperature-sensitive electronics.
