Chinas’s INSANE BREAKTHROUGH Could Replace Boat Propellers Forever

Chinas’s INSANE BREAKTHROUGH Could Replace Boat Propellers Forever 0:00 The development of laser-based underwater propulsion systems as a potential replacement for traditional ship propellers. 1:35 screw propeller 5:44 optical fibers 13:32 Ningyuan Dian Kun 14:26 rotor sail Could a laser really replace the propeller that has pushed ships for nearly two centuries? I explore China’s reported underwater laser propulsion system and the physics behind turning seawater into thrust without shafts, gearboxes, or spinning blades. I explain why screw propellers remain so effective, how cavitation limits them, and how optical fibers, plasma, and supercavitation could change underwater propulsion. I also look at related developments including electric ships, rotor sails, and rim-driven propellers. Finally, I examine the doubts raised by Professor Andrew Higgins about efficiency, noise, power requirements, and the durability of a laser-powered hull. The technology is still a paper rather than a working ship, but it offers a fascinating test of whether light can replace the propeller.
