Rei writes: "Thin film photovoltaic systems have been heralded as a way to make solar cells cheap enough for widespread adoption, but have also been criticized for their low efficiency. A number of companies have been working to fix this equation. Now, one of them — Nanosolar, a privately held company with funding from Google's Sergey Brin and Larry Page — has finally shipped their first cells produced in a mass-production environment. Nanosolar's cells boast being the world's first printed thin-film solar cell in a commercial panel product, the world's lowest-cost solar panel (they plan to sell at $0.99/Watt, compared to the current minimum of $4.83/Watt), and the world's highest-current thin-film solar panel (5x the next closest on the market), among other things. Their Panel #2, made available as a collectors item on Ebay with the profits going to charity, has already racked up bids of over $10,000."

Rei writes: "Yesterday, Slashdot posted about what appeared to be puddles of water sitting on Mars. Unfortunately, according to the Planetary Society's blog, the authors of the paper didn't even bother to check the context in which the "water" photos were taken. The article notes that one shouldn't trust papers that haven't yet gone through peer review. "The white square shows you where the image comes from. It's in the middle of Opportunity's Burns Cliff panorama, on some of the steepest slopes that Opportunity saw before arriving at Victoria crater! Those can't be puddles — unless the amazing "liquid" that puddles here on Mars in a freezing near-vacuum also has antigravity properties.""

Rei writes: "There has been a lot of buzz today over Al Gore: in the wake of revelations that his Tennessee mansion uses 12 to 20 times more energy than usual comes an assault in the New York Times over the accuracy of his film, "An Inconvenient Truth". The article's author quotes a number of scientists who are critical of some of his statements, and describe the film as "alarmism". Quick to the counterpunch is RealClimate.org, which has published a harsh rebuttal suggesting habitual dishonesty and deception of readers on the part of the article's author."

Rei writes: "SpaceDaily.com is reporting the failure of a SeaLaunch Zenit-3SL rocket and its payload, leading some to question whether the damage will prove too much for the company. A split-second after separating from the tower, the rocket fell and impacted the platform with a firey explosion. The failure of the Zenit, a privately developed orbital rocket, comes as SpaceX prepares to launch a new Falcon I rocket after its last failed on liftoff after three successive, failed launch attempts. While the news for simpler private suborbital rocketry continues to look rosy, is private orbital rocketry perched on a precipice?"

Submission + - Report Blasts 'Peak Oil' Theory

Rei writes: "Today, the prestigious Cambridge Energy Research Associates released a report dismissing the Peak Oil theory, suggesting that world oil production will continue to increase for the next 24 years, and then only level into a plateu. The report, which suggests that world reserves are enough to last 122 years at our current rate of consumption, also blasts Peak Oil theorists for repeatedly making unscientific predictions and then shifting them whenever their predictions fail to materialize."
