How dark is dark within the solar system? We suppose black holes, by their very nature, are pretty dark. But high on the list of astronomical objects that don't reflect much light is a new contender: TrES-2b, a Jupiter-sized gas giant around 750 light-years from Earth that's now taking top billing as the darkest exoplanet that astronomers have ever discovered.
Brightness readings measured by NASA's Kepler spacecraft suggest that TrES-2b reflects less than 1 percent of the sunlight that hits it–and that's coming from a star a mere three million miles away from the planet itself (GSC 03549-02811). For comparison's sake, Earth is around 93 million miles from the Sun and, we should note, a whole lot cooler. The average temperature of TrES-2b hovers around 1,800 degrees Fahrenheit.
Although the super-heated planet's atmosphere is full of light-absorbing chemicals, there's no indication that their presence is the direct reason why the planet fails to reflect a great deal of light.
Looks like e-readers are a hot item, as LG is the latest company to jump on the bandwagon. Their devicee has a 10x10 centimeter solar cell that is designed to work in conjunction with the 6-inch TFT LCD. This allows the reader to get a whole extra day of reading with just four to five hours worth of pure sunlight.
Pricing and availability have not been announced as yet, but we’ll keep you updated.

Want your own mini-power plant? Dow Chemical has been working on the project Solar Solutions for the past year. They are developing solar roof shingles and hope to sell them by 2011. In collaboration with Global Solar Energy and home builders, they have been testing them with both simulated hail and fire to make sure they can handle extreme conditions. “The Beast,” a $2.5 million injection and molding machine, produces the shingles that should have a 20 year life span.
