Boeing has won a patent for a protective force field that could stop vehicles from being harmed by explosions, Popular Science reports.
It might sound futuristic — and it is. The patent isn’t about stopping bullets or lasers or anything like that, though. Instead, it detects explosions near a vehicle, and then quickly heats up the air or water between the vehicle and the blast. The heat creates a plasma shield that is more dense than normal air, adding to the vehicle’s protection.
