"In standard solar cells, much energy is lost (as heat) from photons mismatched to the capability of silicon to capture them. A new technique uses a pentacene layer to down-convert each hot (un-captureable) electron to two electrons that can be captured by standard silicon cells."
Insanity. Tootech points out this story for anyone who's been curious about getting that top-secret clearance and the promise of a cushy pension from the CIA, as a reward for decades of blood-curdling, heart-pounding, knuckle-whitening IT service: "Be prepared to go through a lot of scrutiny if you want to work in the Central Intelligence Agency's IT department, says chief information officer Al Tarasiuk. And it doesn't stop after you get your top secret clearance. 'Once you're in, there are frequent reinvestigations, but it's just part of process here,' says Tarasiuk, who also gets polygraphed regularly, though he won't be more specific. For those senior IT managers who are the 'privileged users,' meaning system administrators, 'there is certainly more scrutiny on you,' Tarasiuk says. 'It's interesting: there's so much scrutiny that a normal person might not want to put up with that. But it's part of the mission.'"
"Contrary to a previous story, Google played no part in the Megaupload takedown. From Wired: 'YouTube said Friday that Universal Music abused the video-sharing site's piracy filters when it employed them to take down a controversial video of celebrities and pop superstars singing and praising the notorious file-sharing service Megaupload.'"
"Since its introduction, the Stop Online Piracy Act (and its Senate twin PROTECT-IP) has been staunchly condemned by countless engineers, technologists and lawyers intimately familiar with the inner functioning of the internet. Completely beside the fact that these bills, as they currently stand, would stifle free speech and potentially cripple legitimate businesses by giving corporations extrajudicial censorial powers, there's an even more insidious threat: the method of DNS filtering proposed to block supposed infringing sites opens up enormous security holes that threaten the stability of the internet itself. The problem: key members of the House Judiciary Committee still don't understand how the internet works, and worse yet, it's not clear whether they even want to."
