If it's a filter, how does this help? The problem is that we don't have enough light to activate the receptors not that we have too much light interfering.

I was hoping to see some sort of atomic-scale structure that shifted the frequencies of a tiny amount of infrared light just enough for our visual system to pick it up.

That's almost what it says it does. I think you took the word filter too literally.

It sounds like it might display the image on a thin screen rather than shift the light into the visible spectrum, but it was light on details.

I really want to buy this!

That's an amazing sci fi dream becoming reality.

Wouldn't be surprised if the tech gets confiscated by the military, for national security reasons.

You can buy devices that display infrared everywhere. Only cool thing here is that is passive.
