> An anecdote I've heard is a lot of R&D is focused on these at the moment as they have a higher energy to weight ratio compared to lithium chemistries so are idea for "disposable" use cases such as suicide bomb drones.

You could use normal fuel-burning engines for that, I'd suppose. Or rockets, depending.

The 50k case is not that recent (FLIR Lepton). Not sure about the 0.33MP. The 24x32 is very cheap and as you say, has enough res for some ok applications. I've been intrigued by it and wondered why FLIR seems to still have a monopoly over higher res detectors.
