Boeing has secured the patent for a protective force field that has the potential to prevent buildings or vehicles from getting harmed by explosions. The patent describes a system that would be capable of deflecting or absorbing the shockwave coming from a nearby blast.

It would combine lasers, electricity and microwaves to instantly heat up the air around a target and develop a plasma shield that is denser than its surrounding atmosphere. According to Boeing, the system is flexible enough to be used underwater, making it feasible for boats or submarines as well.
