Chinese scientists say they have developed a prototype of a portable laser weapon called the ZKZM-500, which can emit beams invisible to the naked eye.
The beams of the weapon can penetrate windows and can burn human skin and tissues. The weapon weighs 6.6 pounds and can be as big as an AK-47.
It can be assembled on top of cars, planes, and boats. It is powered by a rechargeable lithium battery packs like those powering smartphones.
