German student creates electromagnetic harvester that gathers free electricity from thin air

via extremetech.com

A German student has built an electromagnetic harvester that recharges an AA battery by soaking up ambient, environmental radiation. These harvesters can gather free electricity from just about anything, including overhead power lines, coffee machines, refrigerators, or even the emissions from your WiFi router or smartphone.

This might sound a bit like hocus-pocus pseudoscience, but the underlying science is actually surprisingly sound. We are, after all, just talking about wireless power transfer — just like the smartphones that are starting to ship with wireless charging tech, and the accompanying charging pads.

How That Football Field Was Blown Up in The Dark Knight Rises

via gizmodo.com

The Dark Knight Rises was pretty incredible for many reasons. But one of the most jaw-dropping bits was when Bane blew-up an American football stadium right at the start of a game. Here's how they actually did it.

Raised turf with holes for people to fall into, pyrotechnics galore, a myriad of stunt personnel—and then literally months spent in the visual effects studio. Worth it in the end, though, because that scene genuinely made the movie. There'll be more where that came from when the DVD lands on December 3rd, and judging by that clip, it might actually be worth watching the special features for once.
