China – Mainland scientists are increasingly confident of developing the world’s first invisibility cloak, using technology to hide objects from view and make them “disappear”.
The central government has funded at least 40 research teams over the past three years to develop the idea, which until now has largely been the stuff of science fiction and fantasy novels like the Harry Potter series.
The technology would have obvious military uses such as developing stealth aircraft, but Beijing believes the research could lead to wider technological breakthroughs with broader uses, scientists involved in the research said.
The main approaches are developing materials that guide light away from an object, creating electromagnetic fields to bend light away from what one is trying to hide and copying nature to make hi-tech camouflage materials. More
