Laser Blast Makes Regular Light Bulbs Super-Efficient 559

A user writes with news that a process using an ultra-powerful laser can crank up the efficiency of everyday incandescent light bulbs. Using the same laser process covered several years ago, the tungsten filament has an array of nano- and micro-scale structures formed on the surface making the resulting light as bright as a 100-watt bulb while consuming less electricity than a 60-watt bulb and remaining much cheaper to produce. "The key to creating the super-filament is an ultra-brief, ultra-intense beam of light called a femtosecond laser pulse. The laser burst lasts only a few quadrillionths of a second. To get a grasp of that kind of speed, consider that a femtosecond is to a second what a second is to about 32 million years. During its brief burst, Guo's laser unleashes as much power as the entire grid of North America onto a spot the size of a needle point. That intense blast forces the surface of the metal to form nanostructures and microstructures that dramatically alter how efficiently light can radiate from the filament."

Sarah Connor Chronicles — Why It Died 834

brumgrunt writes "Sarah Connor was a non-populist, meditative, complex piece of television on a smash-bang, show-me-the-ratings kind of network. The two were never going to get on. Plus: how the Terminator name proved more hindrance than aid."
