Via The Telegraph:
British engineers are developing a new type of defence system that uses lasers to incapacitate pirates by dazzling them as they approach a ship.
The non-lethal weapon, which has been developed by defence company BAE Systems, is effective against moving targets more than a mile away.
The company has started developing the laser in response to the growing threat from pirates to commercial vessels, particularly off the coast of Somalia where there have been several high profile hijackings.
The device effectively hides the vessel carrying it in a bright green glare from the laser, forcing the pirates off course and leaving them unable to aim their weapons accurately.
