Go Greener Tips

But wait! What if traditional bulbs could be made just as efficient as CFLs and keep their cheap price tag?/ppThat’s what scientists at the University of Rochester have discovered is possible and, yes, it involves lasers. A team of researchers have come up with a process that makes a 100-watt bulb consume less energy than a 60-watt bulb by creating nano- and micro-scale structures on the tungsten filament. The structures make the tungsten more effective at radiating light and the bulb much more efficient./ppThe structures are made on the filament by an ultra-intense femto-second laser pulse that lasts only quadrillionths of a second. The power of that minute burst of laser is equivalent to the entire grid of North America, yet the laser can be powered by a wall outlet, meaning implementing these lasers into manufacturing should be a simple task./ppThe process can be used not only to make the light brighter, but to also change the hue of the light by manipulating those nano-structures. If this process is commercialized, all those who want the efficiency of CFLs, but hate the color and price could finally have their perfect bulb.br /br /
