Incandescents May Not Become Obsolete After All


With all the new developments in CFL, LED and HID technology and just try! generic online levitra the fact that countries are lining up to ban them, it's seemed certain that incandescents are on a death march. But wait! What if traditional bulbs could be made just as efficient as CFLs and keep their cheap price tag?

That's what scientists at the buy tramadol online canadian mall 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 canadian propecia rx the tungsten filament. The structures make the tungsten more effective at radiating light and the bulb much more efficient.

The structures are made on the filament by an ultra-intense femtosecond 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.

The process can be used not only to make the light brighter, but to also change the hue of price cialis the light by manipulating those nano-structures. If this process is www.guenstige-versicherungen-online.de commercialized, all those who want the viagra available in india efficiency of CFLs, but hate the color and price could finally have their perfect bulb.

Funny that, all of sudden with more efficient lighting that these bulbs are getting more efficient. I love how that works. Good riddance.

Hm, I think you may need to rewrite this: "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"

so it doesn't sound like the laser is defying the laws of physics :)

Mercury?
written by Kirsten, June 10, 2009
My main beefs with CFLs have been that (a) they do not fit interchangeably in all lamps that use incandescents, and (b) they contain mercury. I presume these new incandescents would not contain mercury?

Last I checked, a 20W CFL would be bright enough to cialis on line replace a 100W incandescent, so a 60W lasered incandescent isn't really that impressive... Also, I'm not so sure they'd be all that cheap, considering the technology involved in creating them.

I hope not, they are the only ones made in USA. Have you read how to discard a CFL bulb if it breaks? scary. I sure won't buy anything else after I started noticing all my money was going to China.

I love the idea of a laser in my light bulb that also helps the wow look it generic viagra soft tabs environment.

Trade-Off
written by Kirsten, June 10, 2009
I don't know. Only half the power savings of a CFL, yes, but none of where can i buy levitra the mercury. It doesn't sound like a CFL is necessarily the automatic winner. I mean that mercury has got to add up at some point when people start throwing out their CFLs.

What a lame article. LEDs are the way forward.

Step in the right direction.

One of the main stumbling blocks to the sustainabilty movement has been that many people just don't want to change the way they do things or what they buy. Some don't like the color of CFL's, others are concerned about the mercury they contain. LED's are great, but they too have a way to go. More efficient incandescent bulbs = a great step in the right direction.

It would be hilarious if through new technology incandescents become more efficient than CFL. Because of various laws it would require people to usa pharmacy cheapest viagra use less environmentally friendly bulbs. ... one of the hazards of governments trying to pick winners with rapidly changing technology.

how does a 100 watt bulb consume less than a 60-watt bulb? Am I missing something? It wouldn't be a 100 watt bulb then would it?

The problem pointed out above is what it is about.......we want to use less energy for our lighting. Thus, laws should be limiting the amount of electrical power needed per unit of light. That way you don't block future developments.

In the real world politicians don't think up limits such as banning incandescents or limits on W/Lumens. Those are designed by lobbists, looking to create a bigger market for their product.


LED lights consume less active power, causing your electricity bill to decrease. Yet, alot of cialis buying online them have very poor power quality in order to produce them cheaply, causing increased losses further on in the electricity grid.

Considering regular bulbs, also remember they dont last as long is that going to be saving much
