Boeing Patents a “Plasma Force Field” that is “Powered by Lasers”


On first look, it seems that they’re onto something similar to “Star Wars'” deflector shields. The patent describes a system that would detect the shockwave from a nearby explosion and create an area of ionized air — a plasma field — between the oncoming blast and the vehicle it was protecting.

The method works, says the patent, “by heating a selected region of the first fluid medium rapidly to create a second, transient medium that intercepts the shockwave and attenuates its energy density before it reaches a protected asset.”

By creating a temporary, superheated parcel of air with a laser, microwave or electrical arc, researchers believe that the shockwave would, in theory — it hasn’t been determined how far along Boeing’s research into this has got — dissipate once it hit the plasma field, leaving whatever was on the other side unaffected, or for the blast to at least be mitigated.
