Boeing has apparently filed a patent for a real, working forcefield.
Actually, they filed it two years ago and, of course, kept the details hidden. Apparently it relies on creating a "backwash" of sorts through rapid heating that dissipates the shockwave from the explosion. Kind of like how the Flash stopped the tsunami in that recent episode.
It's a transient forcefield, rather than "up shields" (And the source article seems to think forcefields are common in Star Wars, where they are almost never used. I think you mean Star Trek, people).
But it is a protective forcefield. And I am now wondering if the same principle - sending a wave of something out - might also be used to protect against radiation. Thoughts?
