Imagine Chinese soldiers armed with death ray weapons that can cause crippling pain by burning you from the inside out at long range. China has that weapon: the Poly WB-1. It's a concentrated microwave beam that works exactly like it sounds: like your insides are being put in a microwave oven.
The Poly WB-1 excites the water molecules inside your body to produce intense pain and it can be fired from over half a mile away. China claims the weapon is non-lethal, but I can only imagine what extended use could do to a human body - it sounds like a torturous way to die.
Even so, it could be a preferable alternative to the deadly weapons we currently use to fight wars. ExtremeTech reports:
While a pain beam sounds absolutely terrifying, it’s arguably a step in a safer direction for military conflict than the tried-and-true lethal favorites of bullets, bombs, and fire. It’s also a much safer alternative to weapons that use chemical or biological agents.
The weapon is by no means handheld, and must be mounted on a truck, tank, boat or other motorized vehicle.
