- guytoronto, on 07/23/2008, -20/+146Yup. Another "breakthrough" that will "change the world". These things seem to happen every other day here on Digg. At this rate, my entire house should have ultra-mega-super-high efficiency lighting all powered but super-awesome-mega-ultra efficient solar panelling the size of my thumb.
- obsolite, on 07/23/2008, -4/+79Thank god, I'm so tired of paying $5 for 100 LEDs. Not to mention changing them every 50,000 hours. What a hassle!
- cuevas4711, on 07/23/2008, -10/+69BOILER UP!
- ilistenisee, on 07/23/2008, -9/+57go Purdue!
proud of Purdue engineering :) - stonewall123, on 07/23/2008, -1/+35Actually, energy efficient products are here already and they get better every year with these improvements. Its evolutionary not revolutionary improvements that blend in so well that you hardly notice them. Computer chips get noticeably faster, smaller and more energy efficient every year. Energy star rated products ( dishwashers, air conditioners, etc ) increase in efficiency every year. Hybrid vehicles are improving at a very steady space. There is even a company ( Capstone turbines I think ) that now manufactures small highly efficient turbines to improve efficiency of hybrid buses by almost 30%. That technology is also being applied for many other processes to improve energy efficiency. In terms of LED lighting you wouldn't recognize LED lights as of 10 years ago. CREE, located in North Carolina, is a company that produces LED bulbs that are fantastic. Now you can buy LED lights (www.earthled.com ) that look and feel just like conventional light bulbs. 10 years ago you were limited to those ugly blue tinted LED's now you can get the nice warm colors (~ 2700K) that we expect in our homes. Sure, they are a bit more expensive but still affordable of the long term and will be even more so when economies of scale kick in. Point is there is actually a ton to be excited about. People just need to stop talking and just start using these new technologies.
- DoubleDarkHorse, on 07/23/2008, -0/+26I love the usage of all the "coulds" and "ifs" in stories like these.
I could become Tiger Woods if I knew magic. - CosmicJustice, on 07/23/2008, -7/+26This is great but, increased efficiency does not lead to reduced consumption. Over the past 50 years the efficiency of every electrical device in our houses has increased dramatically, from TV's to washing machines, but per-capita electricity consumption has climbed or remained steady as we add new appliances based on the new, more efficient, technologies and use them more because we can afford to.
- yisforyeti, on 07/23/2008, -0/+18Here's an article with some more detailed information:
http://www.sciencedaily.com/releases/2008/07/08071 ... - McSwankypants, on 07/23/2008, -0/+15Also, keep in mind that most of these "breakthroughs" you hear/read about on Digg are from University research labs. I would venture to say most "breakthroughs" have just been published. Now, they have to take the time to clean up the work a bit, devise a means of manufacturing said product/licensing said product, etc., etc., ad nauseam.
- stonewall123, on 07/23/2008, -0/+15Can you imagine if things had not become more energy efficient during that 50 years?
- sockpuppets, on 07/23/2008, -7/+21You make delicious chickens, I can't wait to taste your LEDs.
- Junkey, on 07/23/2008, -0/+12This is great news for the Light Bright enthusiasts.
- krnldmp, on 07/23/2008, -1/+11For any living species only death leads to reduced consumption. The interesting thing about humans is how quickly we are able to do more with the same amount of energy and process it from different and more harmoniously tapped sources.
- waldo21, on 07/23/2008, -3/+12Submitted the Science Daily story on this a day or so ago, and got one digg.... guess I need more digg friends.....:-(
- d2htornado, on 07/23/2008, -3/+12Train Whistle: *toot* *toot*!
- ferrell, on 07/23/2008, -0/+8Uh, no...
http://www.theledlight.com/par38.html - mikegee24, on 07/23/2008, -0/+8Comparing the title and description of your submission to this one, its obvious why this one made the front page and yours did not. Yours is not over-stated and dramatic like this one. Your description contains actual technical details (boring).
- o5rob5o, on 07/23/2008, -2/+10i wish i did something meaningful at Purdue while taking engineering
all I did was drink beers and work on thermodynamics for 6 hours a night - pinchduck, on 07/23/2008, -0/+7The time from Lab to Wall*Mart is a few years. They have to figure out how to produce it efficiently and make sure that everyone makes a profit along the way. Combine the profit motive with green technology and we will live an a very different, vastly improved world.
- kmohr25, on 07/23/2008, -3/+8You have a point here. Every day some new technology on Digg is out there saying it will reduce energy consumption and change the way we live today. But, I don't think I will ever see this stuff in my lifetime ...
Still proud to be a Purdue ECE student! - inactive, on 07/23/2008, -0/+5Hey, at least you were in engineering. I was a theatre major. But that's okay. It paid off too. Go Purdue!
- cawpin, on 07/23/2008, -0/+5No, you just need to submit the actual source,
http://news.uns.purdue.edu/x/2008b/080717SandsLigh ...
or have a spamming setup like treehugger. - suckaPU, on 07/23/2008, -1/+6just graduated from there... that school does some cool stuff
- Protuhj, on 07/23/2008, -0/+4Increased efficiency for lighting is a good thing, the article stated (not sure of accuracy) that about 1/3rd of the electricity consumed in the US alone is from lighting.
For most of us, our lighting habits won't change, maybe businesses and advertising agencies will use more of the lights because they are cheaper to run, but for the average consumer this would be a very welcome change. - starbar, on 07/23/2008, -0/+4That's why they will cost more...they will never be incandescent cheap but will still be worth it.
- MeteoMan8314, on 07/23/2008, -3/+6BTFU!
- ProjectGSX, on 07/23/2008, -0/+3These daily world-changing breakthroughs could explain why the world keeps changing.
- Jektal, on 07/23/2008, -0/+3They never claimed it would be made in the US, just that it'd be cheaper and more efficient.
- hockeyisgd, on 07/23/2008, -0/+3I remember ENGR 106, CS158, PHYS 152...now I'm there for Political Science...
- humperdeath, on 07/24/2008, -0/+3Thanks Lewie, thats what I;m talkin' bout. Now cut the price in half!!!!!!
- nsapra, on 07/23/2008, -0/+3EE represent!!
- rowlodge, on 07/23/2008, -0/+3probably take ten years to get here like every other break through there is , since Digg started, i wonder if there has been one story that has been on digg that has come true?, think about it.
- Kajarago, on 07/23/2008, -0/+3@ vtron:
re-RTFA - inactive, on 07/23/2008, -1/+4No, it's funny in print form as well.
- swatward, on 07/23/2008, -4/+7I'm going there this fall. :)
- Lewie, on 07/23/2008, -0/+3http://www.dlp.com/hdtv/led_hdtvs.aspx
- michigander, on 07/23/2008, -0/+2when did he ever mention lightbulbs?
- xxsk8rguyxx, on 07/23/2008, -0/+2Kajarago is right.
FTA: "Old LEDs vs. New LEDs
What makes traditional LEDs so expensive is that the light-emitting layer of an LED light is a gallium nitride crystal and it needs to be treated in various ways with expensive materials." - DerangedPenguin, on 07/23/2008, -0/+2each LED will cost you a negative $.01, they will be come like the lint that accumulates around the base board of your living room.
- chubbybubba, on 07/23/2008, -0/+2just a matter of time before led implants.
- GliTCH82, on 07/23/2008, -0/+2Seems to me like you guys are waiting for these research breakthroughs to manifest themselves in products that advertise themselves with "Remember this? You read about this in Popular Science 5 years ago!"
Obviously that's not how it works. Perhaps sometimes a product is so novel and amazing that it deserves its own company, brand and advertising campaign, but in all likelihood this technology may just come out as a new GE bulb line for your home in a few years for a cheaper price, longer life, and chances are you won't even notice it then. - Lewie, on 07/28/2008, -0/+2When that happens, I'll be in line right behind you!
- weaponR, on 07/23/2008, -2/+4Purdue Science...
always overshadowing the technology school :(
Boilers pwn. - Fathom, on 07/23/2008, -0/+2Krannert is da bomb
- tas08, on 07/23/2008, -0/+2That sounded like a Mitch Hedberg joke.
- 33PercentGod, on 07/23/2008, -0/+2Weird science!
Magic and technology!
Voodoo dolls and chants!
Electricity! - behlib99, on 07/23/2008, -0/+2How is this going to change the world?
- humperdeath, on 07/23/2008, -0/+2And when can these LED be used in big-screen TV? I want that 60 incher for under $1000, and like right now!
- Kanele, on 07/23/2008, -0/+2i couldn't digg you up if i was blind
- caseclosed326, on 07/23/2008, -0/+2They have 9 year light bulbs out right now. The current companies may not love the idea of losing repeat customers but plenty of upstarts will be willing to seize a quick buck no doubt.
