Pirates of the Indian: The Curse of the Soundwave

The pirate attack of an ocean liner off the coast of lawless Somalia is getting a lot of attention. The Times of London points out an interesting wrinkle - that the ocean liner defended itself with soundwaves.

"The liner used a sonic blaster to foil the pirates. Developed by American forces to deter small boats from attacking warships, the non-lethal weapon sends out high-powered air vibrations that blow assailants off their feet. The equipment, about the size of a satellite dish, is rigged to the side of the ship."
