“People have said that high-efficiency up-conversion of infrared to visible is impossible because of the amount of information not collected due to the angular loss that is inherent in non-local metasurfaces,” Boy, I wish I had a nickel for every time I've said that!

Still waiting on the X-Ray glasses from the back of the comic books.
To: Red Badger
The “pump beam” would seem awkward in practice. How do you implement that without making the thing bulky?
To: Red Badger
Hmm. Could an automobile windshield be treated with it?

They’d be great for night time deer hunting. Wouldn’t have to bother with that bulky spotlight.

Wondering if solar panels could be made more sensitive to low light conditions.
I’m way out of my league here, just spitballing

The article discusses that this film could be applied to any transparent surface. I’m thinking that maybe in the future we would be able to have a pair of Sunglasses and a similar pair on Nightglasses. That would be super for night driving and just being outside at night if it really is that similar. I would definitely want a pair, today, please!
