The nano-crystalline coating is very expensive and difficult to produce, and, so far, there aren't a lot of ideas as to how to mass produce these things."
- MasterThief117, on 03/05/2008, -6/+61This was a very bright idea, whoever came up with this.
- scarz99, on 03/05/2008, -1/+38WOW That graph really explains a lot about it! I mean look, no actual data is displayed but, I know its better cuz its BIGGER!!!!1

Here's one more try.

- NJank, on 03/05/2008, -0/+22that's why engineers take over for scientists somewhere along the road to WalMart
- diggB, on 03/05/2008, -6/+26For the serious geek, here's the published article which explains the science behind the LEDs titled "Color-converting combinations of nanocrystal emitters for warm-white light generation with high color rendering index" which appears in Applied Physics Letter.

Don't ask me to explain it. I'm too stupid. - MrStabby, on 03/05/2008, -2/+21Diodes...that emit light?
BRILLIANT! - dsmx, on 03/05/2008, -1/+19Brilliant news, when they figure out how to make it cheaply we will have a way of dramatically reducing electricity demand in lighting.
- jasonmantey, on 03/05/2008, -0/+17"Nanomaterials" is a bit vague to argue that toxicity is "inherent". Yes, it is true that nanoparticles (zero-dimensional sized particles) like carbon bucky balls pose safety concerns - but most nano-electronics are grown on macroscopic [silicon] wafers and simply have nano-sized features. These do not pose the same threat, since these nano-sized devices are not going anywhere.
Nanoparticles in suntan lotion, for instance, are potentially much worse than nano sized heterostructures in the electronics industry. - Samsong, on 03/05/2008, -0/+16"You look like a smart, young man," he said, and Zoidberg knows it when he sees a deal!
- diggB, on 03/05/2008, -6/+22Apparently, I really am too stupid. Here's a link that actually works ...
http://www.bilkent.edu.tr/~volkan/publications/APL ... - TheKrillr, on 03/05/2008, -0/+132x more efficient than the energizer bunny?
- N256, on 03/05/2008, -1/+122x more efficient than resistors?
- carpespasm, on 03/05/2008, -1/+12nanomaterials encased in plastic or mercury encased in thin, brittle glass. Which is more of a threat?
- Daiken, on 03/05/2008, -0/+11Sounds great...just like all the other research you hear about. It only takes a little while before you start to realize 95% of the things you hear/read about never come to market for one reason or another. For the small percentage of developments that the consumer sees, you end up waiting 5 or 10 years till they finish further research and testing. Call me when it's available in stores.
- centran, on 03/05/2008, -0/+10Don't re-edit your comment when you put a link in it. That is what breaks the link. If you want to re-edit your comment then make sure to paster the entire link again.
- strictnein, on 03/05/2008, -0/+10A refrigerator lasts for 20-30 years, but companies still make money selling them. Lower quantity = higher prices.
- adrianmonk, on 03/05/2008, -0/+10Yes, but it's the easiest to attack. Most people, hopefully, know how to change a light bulb, and what's more, many of them are willing to do it. Fewer people are likely to upgrade to a new A/C unit because it's really expensive, and it won't pay off for years.
By the way, Austin Energy (the city utility here in Austin) has a program to upgrade refrigerators. They give you something like $50 if you allow them to haul off an inefficient fridge (and you replace it with an efficient one). - N256, on 03/05/2008, -0/+9They do it quite efficiently.
- MioTheGreat, on 03/05/2008, -1/+10When you're dealing with this kind of stuff, the line between engineer and scientist gets kind of blurry.
- VegaObscura3, on 03/05/2008, -1/+9I'm pretty sure lighting is one of the smallest contributors to our electricity bill. If I'm not mistaken refrigerators and central heating/cooling (if you have it) are among the largest contributors.
- TheKrillr, on 03/05/2008, -0/+8Yes, they do.Like the big one in the bottom of my oven.
- inactive, on 03/05/2008, -0/+8Its funnier if you imagine the finger snap and head bob at the end...
- jackminardi, on 03/05/2008, -0/+7Are you seriously that stupid?
econ 101, try it out. - Tenoq, on 03/05/2008, -1/+8Incandescent bulbs were no better though:
"The incandescent bulbs indirectly result in mercury releases to the environment too.
The life-cycle analysis found that when you consider the mercury produced from burning coal for electricity, the energy hungry incandescent bulbs contribute five times more mercury to the environment than CFLs do."
From www.abc.net.au/science - 13B1303, on 03/05/2008, -4/+11The city of Ann Arbor: "can we get a refund?"
- makkaveli19, on 03/05/2008, -0/+7YAY you finally got it :) i dugg 'em all
- Daiken, on 03/05/2008, -0/+7911-5368
- sexybobo, on 03/05/2008, -0/+7Reread what he said. He said the exact same thing you did and you are arguing with him
- inactive, on 03/05/2008, -0/+6whats your number?
- trogdor282, on 03/05/2008, -4/+10Just for the record you would have to eat a CFL to get a noticeable dose of mercury.
- inactive, on 03/05/2008, -1/+7What happens when people throw all of the CFL away? It will build up. People are going to be too ignorant to drop them off somewhere.
- jonohull, on 03/05/2008, -1/+7Like the Torch? http://www.engadget.com/2008/01/28/the-torch-why-i ...
- amawg9, on 03/05/2008, -0/+6867-5309
- strictnein, on 03/05/2008, -1/+6It's not one of the smallest, but it's not the largest (from 2001):
The top five (percentage of total):
Air-Conditioning 16.0
Refrigerators 13.7
Heating 10.1
Water Heating 9.1
Lighting (indoor and outdoor) 8.8
http://www.eia.doe.gov/emeu/recs/recs2001/enduse20 ... - TheOther1, on 03/05/2008, -0/+5Yes, it's a shining example of efficiency.
- lucutus, on 03/05/2008, -0/+5If your resistor is giving off white light then it is loosing efficiency and is probably not going to last much longer.
- jasonmantey, on 03/05/2008, -0/+5I'm a grad student in micro/nano electronics at UT Austin, but I also did a [somewhat informal] talk about nanomaterial safety concerns during a summer undergraduate research program at Penn State (unfortunately, I don't remember my official sources - but I'm sure they can be found via google / google scholar)
- Portezbie, on 03/05/2008, -0/+5I'm really fond of my led flashlights :-P
- HonestAbe, on 03/05/2008, -0/+5Start your own business and market your LED lights as long-lasting and prove them all wrong.
- Clevinger, on 03/05/2008, -0/+5Bad graph, but FYI, the scale is lumens per watt.
Nano crystal LEDs = 300 lumens/watt.
CFLs = 80 lumens/watt.
White LEDs = 60 lumens/watt. - chungmaster, on 03/05/2008, -0/+5Sounds like that gum commercial where people never seem to finish their gum.
- Tenoq, on 03/05/2008, -0/+5Depends on your personal use. We deliberately avoid using the air con at our house unless it gets unbearably hot (ie, 40+ degrees C outside). We have no real insulation either, which is bad, but just keeping the house locked up during the day is usually enough to make it tolerable. We also have gas heating for the winter, and gas hot water - both help our electricity bill (gas is many times cheaper). Our biggest contributor to our bill is the PCs in the house, followed closely by our very small fridge. Then it's lights, lights, lights - but most are CFL too now.
- JQP123, on 03/05/2008, -4/+9It's probably similar to the new hybrid automobiles ... the added cost of the product is more than can be recovered from energy savings.
- xkorbin, on 03/05/2008, -2/+7*****, I've been making nanocrystals in Anarchy Online for years. Just roll a meta physicist and you're set to go.
- BaronVonZ, on 03/05/2008, -0/+4I cant wait for the day when moving into a new house means living in the dark for a week because the previous owners took their forever-lightbulbs with them...
- blorguehad, on 03/05/2008, -1/+5its a shame cos i really want a uber bright flashlight...
- Gnasche, on 03/05/2008, -0/+4The overlooked question here: "Is this gonna screw with my Wii remote?"
