How about a flashlight that is cooled by “li-900”, the ceramic that was used in space shuttle tiles? You could cast a triple spacer for a convoy s2 out of this stuff! Does anyone here have connections at Lockheed?
It would be nice to have a 3000 lumen pocket light that can run on turbo till the battery dies.Remember this is just fiction.
I’ve seen one fanwork of The Martian where Watney uses an RTG to warm up the rover while he goes looking for Pathfinder. After much failure and overheating, he makes it work.
A “people recognizing” light is already in the works. But it is for car headlights that selectively dim parts of their beam to avoid blinding everyone on the road.
Petzl has a crude version of this in their $400 industrial headlamps. A pair of IR transcievers mounted in the headlamps will automatically crank down the output when it is pointed at someone also wearing a $400 headlamp.
I still have one; readapted with a reflector with three low power LEDs; it will give about 60 lumens, but to get around at home it’s fine; I run it with two “D” “SUPERPILA” at nikel cadmium dating back to the 80s, but they still work
Black photons — invisible at the source, which only become visible when reflected from something more solid than air.
