Wows crowds at TED conference, but admits research into the area is still at a very stage
A working invisibility 'cloak' has been demonstrated at the latest TED conference.
A small box made of calcite optical crystal was shown bending light around an object. Anything that was placed behind the crystal became 'invisible'.
According to the scientist behind the device, Professor Baile Zhang from Nanyand Technological University in Singapore, he had developed the invisibility device 'just for fun'.
"I just think the idea is cool," he said, reported The Telegraph. "Plus, I hope this work will demonstrate that simple tools can sometimes fulfil important functions that previously required complicated methods."
However, he admitted that research was still at a very early stage and that "at this stage, this is the best we can do", before adding "There will be quite a long way to go before it can be applied on a practical level. But all researchers in this field, including myself, are making progress, albeit slowly."
