Tesla Motors - Leadership: "He claims that he departed on his road trip with a full charge and drove conservatively, around 60 mph, and yet he got stranded on his way back"
"So we consulted the trip information our car stores in its firmware. We found that Colwell departed for his trip from Ann Arbor to Saginaw with only 85 percent state of charge. He had charged in “standard” mode, not “range” mode, the preferred mode by customers who have long-distance hauls. Colwell averaged between 70 and 80 mph, and went north of 80 a few times, significantly more aggressive than his claimed 60 mph average. (Some in the office wondered if maybe his speed is what attracted the attention of the trooper he mentions in his piece.) Colwell also claimed to have driven conservatively, but the logs reveal that his energy usage ranged between 300 and 400 Watt-hours per mile (Wh/mi), not conservative by any measure."
Be careful what you say when a computer is logging your actions! :-)

Walking like Spider-Man may not be so far off | Crave - CNET
Walking like Spider-Man may not be so far off | Crave - CNET: "A one-square-inch contraption with millions of holes sized at 1 micron each, for example, could hold more than 15 pounds--clearly far from enough to sustain a human climber, but a big wall shimmy in the right direction."
So could a 5" diameter circle (~20 square inches) hold 300 lbs? That would easily hold most humans!

FBI wants records kept of Web sites visited | Politics and Law - CNET News: "The FBI is pressing Internet service providers to record which Web sites customers visit and retain those logs for two years, a requirement that law enforcement believes could help it in investigations of child pornography and other serious crimes."
Of course big brother is better and investigating crime, but we also balance that with personal rights and limiting government power.
