Date a Fire
Okay not sure exactly how this would work but woke up this morning wondering if there was a way to use a device to quickly map out a fire by carbon dating the room. So you’d set the device on a tripod in the middle of a room and then it would scan the room and determine the age of the burned areas. Then it would send the data to a program to quickly map it out in 3D for fire investigators to look at.
Of course later on the device could be miniaturized to the point that it would be a attachable to someone’s helmet and then display the data in real time on a small heads-up display, like fighter jet pilots have. Sort of a roadmap would be super imposed on the room. I’m guessing different shades of colors to indicate age of burned area.
