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. This diagram from Boeing shows the different parts of the force-field system: Boeing’s patent application shows how the force-field technology could work with a military vehicle: The above diagram shows a military Humvee with a device that can lessen the impact of explosions from bombs like improvised explosive devices (IEDs). But there could be other uses for Boeing’s force-field technology. Boeing notes that it can be used in water as well as air, heating up the area around boats or submarines to less...
