Noah's recent posts on the Airborne Laser and reflected laser beams reminded me of a spoof on a Pentagon PowerPoint briefing that was making the rounds in the Defense Department a couple fiscal years ago. Better than any article, this briefing captures everything that is wrong, funny and horrifying about outrageous Pentagon weapons that sound too good to be true. I'm posting the briefing, called Directed Energy Sea Mammals, for those who weren't on the e-mail chain when it first came out. The author of the original Air Force PowerPoint is a mystery (I've also seen a Navy variant of it).
