Here's the thing about cool sci-fi tech, it is just like every thing else. It is easier to say you're making this sensational thing like shields as a first step to star trek deflectors to grab headlines. Most of the time, the invention either doesn't pan out, or like some Sony's stuff isn't quite as neat as they said it would be. I haven't heard much from those cloaking field, hydrogen cell, cold fusion, airship, rocket pants engineers past their statements 'were close to completing (blank)'. I'm not saying don't try to make it, but don't oversell it either.
