Isn't Popular Mechanics the rag where half-baked technologies go to die? Right after the part where they will revolutionize All Life As We Know It? And right before the part where The Idea is killed by an Evil Conspiracy?
They are usually late with the important news and way too early with stuff that will eventually crash and burn. Not that they can't build a raging headline and a totally misleading cover out of it.
I stopped going to Popular Mechanics for my cutting edge technology news when I was about nine years old. They are long on hype and short on details - not to mention short on discrimination in their editorial department.
Excuse me, but the nuclear battery in my flying car is running low. Gotta run...
