Note that an square of 400 x 400 km equals 160,000 km, not 400 km.

The amount of materials needed to cover such a square with a solar plant probably exceeds the world's production capacity for iron, aluminium etc in a calendar year (I made some rough numbers some years ago).
That is without counting the energy needed to build such a plant...

ActionDesignStudios writes "The upcoming release of Ubuntu, titled 'Lucid Lynx,' has just entered the beta cycle. Alongside the usual desktop and server versions, a special version has been released that is designed to run on Amazon's EC2 cloud service. This release of Ubuntu does away with the brown 'Human' Gnome theme we've all become accustomed to, replaced by a new version Canonical says is inspired by light. The new release also includes much better integration with social networking services such as Twitter, identi.ca and Facebook, among others."

Laughing Gas Is Major Threat To Ozone Layer 306

Hugh Pickens writes "The Christian Science Monitor reports that according to new research, nitrous oxide, the colorless, sweet-smelling gas with a long history as a medical and dental anesthetic is the next big threat to Earth's protective ozone layer. Its role in destroying ozone has long been recognized, as well as its role as a heat-trapping greenhouse gas but the new study puts nitrous oxide's ability to deplete ozone into numbers comparable to those used for other ozone-depleting gases covered by the 1987 Montreal Protocol. The researchers note that the health of the ozone layer has been improving since the adoption of the protocol and that nitrous oxide looms large today as an artificial destroyer of the ozone layer, in part because the emissions of other harmful chemicals have been so sharply reduced."

Apple Admits Nvidia GPU Defect In Some MacBook Pros 89

bigwophh writes "The brouhaha over defective Nvidia mobile graphics chips keeps rolling along, even months after the initial headlines have faded. Despite Nvidia's promises that Apple's GeForce 8600M GT-based MacBook Pros had dodged the bullet and were immune from the defect, Apple now counters that it wasn't, in fact, so lucky. 'In July 2008, NVIDIA publicly acknowledged a higher than normal failure rate for some of their graphics processors due to a packaging defect. At that same time, Nvidia assured Apple that Mac computers with these graphics processors were not affected. However, after an Apple-led investigation, Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected.' The units in question are the 15-inch and 17-inch MacBook Pro notebooks with Nvidia GeForce 8600M GT GPUs, built between May 2007 and September 2008."
