It uses nanotubes to create an underwater mirage. The nanotubes heats up to a high degree and transfers the heat to the surrounding area. The high temp gradient causes the light waves to bend around the area. Concealing what is behind.
Not much different than a mirage you might see on a hot day coming from the road in front of you.

Mr fancy pants...always have to one-up eh?
I think the next 50 years are going to blow the doors off the last 50 in terms of technological advancement. It is scary what my grandkids are going to be using to debate why the Cubs haven't won a WS in 150 years.

Ok, smart guy, serious and related question: when I see that puddle of water up ahead in the road on hot days, and it isn't actually there, why can I see a reflection in it? Like, if it isn't actually water (which it isn't), how is it - from a physics perspective - that I can see a reflection of cars up ahead in the "water"?It uses nanotubes to create an underwater mirage.

The researchers found that it works best under water. A typical mirage ,if I'm not mistaken, occurs when the temperature near the surface is hotter than the air above. this causes the light to be bent up. The viewer is actually seeing a reflection from the sky and our eyes perceive this to be a more common occurrence (pool of water).Ok, smart guy, serious and related question: when I see that puddle of water up ahead in the road on hot days, and it isn't actually there, why can I see a reflection in it?

With the nanotubes they are able to do this over the entire optical range.

Ok, so it's like the light is bending in a V shape (from my eye to the ground back up to the car I see "in the water"). That's crazy. And cool.The researchers found that it works best under water.

Very well said. By the way I am not trying to be "that guy". Just saw the picture above and knew what it was about and thought I'd share a bit of the science. I was talking about it about a month ago on an Engineering forum I frequent.Okay this site is getting to smart so let me add:

I'm just bustin ya balls, I find this discussion and the science behind it facinating, I'm sure at some point I'll geek out about literature... Keep the knowledge coming.Very well said.
