This headline is wrong. This has nothing to do with thermal cameras. It's "cloaking" by making it appear to have the same bulk thermal properties as it's surroundings.

Yes. Unfortunately many people are reading this thinking it's a FLIR invisibility cloak.

FYI Ukraine already has FLIR invisibility cloaks (fancy camo space blankets): https://www.youtube.com/watch?v=GfdF3iIwoX4

This is thermal cloak, explained here: https://www.youtube.com/watch?v=CM2RJi4mRZ0&t=52s

Notably it only works after the heat flow settles back down to equilibrium. If you're moving, it doesn't work.

Which seems like it would be good for fixed installations that need to remain undetected, no?

		The other caveat is that it only works if you're embedded inside a solid object. ;) If you're in free space, the surface can't shine its IR differently in different directions, so under FLIR it will just look like the average ambient temperature. This is no better than existing (cheap and light) space blanket camo systems.
