First we had Star Trek and their little handheld communicators... then we had cell phones.
Next up we have Westwood Studio's Command & Conquer Red Alert (even before that really, since I know Nikolai Tesla did the original scientific theory that was used as the basis for the game) where they had what amounted to a Tesla Coil on crack... well, now the Army has their version of the game's Tesla Coil, using a laser to guide the electricity to the target with enough power to fuel a large city. 50 billion watts right to the target, in less than a second.
Thankfully they didn't report the range, or the exact design. Hopefully they'll keep that a secret as long as possible.
