Invisibility, fusion and interstellar space

Perennial subjects for science and technology writers include Voyager crossing into interstellar space, commercial fusion power and invisibility cloaks. We are eternally on the brink of those last two—"very close." Don't hold your breath, and look for a better investment.

This latest "invisibility" cloak sounds a lot like noise canceling headphones. Completely nullifying the signature of an object—even across a wide spectrum—might make it stand out more than other forms of "invisibility" already in long practice, such as misdirection.

The one "invisibility" cloak that made me roll my eyes was nothing more spectacular than the kind of front projection employed by movie VFX artists. It's highly effective—provided you can get your enemy to wear a special visor and guard the perimeter using only one eye.
