Bomb Calorimetery is a PITA, I almost did a startup around this. The researcher in the video has a fairly manual one, there are automated setups that reduce this time, but they still cost $40k+ and require oxygen tanks, etc. The even more difficult case for calories is something like a steak: how marbled is it? I could see some computer vision approach working.
