Boeing granted patent for device to shields vehicles against shockwaves . The device uses sensors to detect an explosion and anticipate blastwave . An 'arc generator ' uses lasers , microwaves or electric current to ionise the air in front of the shockwave so that it deflects and reflects the energy . This is a very simple idea but has been around since at least the early 1900s.
Boeing granted patent for device to shields vehicles against shockwaves . The device uses sensors to detect an explosion and anticipate blastwave . An 'arc generator ' uses lasers , microwaves or electric current to ionise the air in front of the shockwave so that it deflects and reflects the energy . The arc of ionised gas - or plasma - would also absorb shockwave energy . Boeing says it can protect tanks , buildings , ships , aircraft and submarines .
