Since the human body contains 60% water, why is it that the microwave emitter heated up water in sewers but didn fry the humans near them?
Answer 1: This is a plot hole. Answer 2: It’s stated in the film that the device uses “focused microwaves” to vaporize an enemy’s “water supply.” No additional information is given, but apparently the device has a sensing/targeting system of some kind, or was aimed at the underground pipes by its users. If the latter is the case, it might well have killed anyone below the train as it moved across town, though this is never shown. Answer 3: Water inside the human body is not simply liquid stored in a continuous pool; it is compartimentalized and contains a pleithora of organic substances, such as large molecules, complex proteins and even entire cells (red blood cells, immune cells, etc.). Perhaps these, as well as cell membranes/organs protect the water in the body from evaporating by absorbing the microwaves, or in some way increasing the bonds between the water molecules strong enough to prevent them from evaporating. In any way, the device would then only affect pools of water with
