Invisibility Cloaks Aren’t Just for Harry Potter

Invisibility Cloaks Aren’t Just for Harry Potter
Cats got one step closer to world domination last week when scientists in Singapore and China premiered a box that could effectively make anything placed inside it invisible. The magical box is just one of three new “Harry Potter”-style invisibility cloaks announced this month, which follow numerous such announcements made so far this year.
The invisibility box comes our way via Dr. Zhang Baile, a researcher with the NTU School of Physical and Mathematical Science. His team’s small device — the details of which were published in the journal Nature Communications — is called a “ray-optics cloaking device.” It’s a small, glass-like box made of more than two dozen internal and external angles that effectively bends light around anything in its center. When light is shone at the semi-transparent box, it passes around the box instead of through it, effectively masking whatever is inside. Zhang and his fellow researchers tested his device with live cats and fish, as you can see in this image from the paper:

I remember reading something about this in USA Today back in 2005 or 2006ish. At the time they were figuring out ways to hide unsightly billboards that spoiled the countryside.

I think this is only going to lead to no good. Might lead to a way for people to hide weapons when entering an airport or other place. Bombs inside of luggage could be made invisible. This is not a good thing to develop.

Not sure why this is on the care2 site as I can only imagine any of these to be used for military purposes.

Interesting. I agree that mis-use can be a dangerous thing, especially in times of war.Scary in many ways.
