@blueveinedthrobber,
Of course, so far, the doomsday event hasn't happened yet and it's been more often predicted and discussed online and in media than Kennedy-assasination-theories.
And the modest amount that I know of physics and electrical supplies that it'd take to power it, this thing couldn't be hooked into the electric grid or it'd create such a blackout, it'd be amazing.
Also as regards any computer electronics, the potential EMF pulse it MIGHT create could cause a complete breakdown in any nearby computer system, including it's own. I'm way out on a limb here, though, as I know that EMF pulses of this sort are created by thermo-nuclear devices like A-bombs.
When it (doomsday-bad-hair-day-extraordinaire) happens, I hope I can get all the dust-bunnies under my bed all scooped up and have my HDTV paid off.
