NuttierThanEver: You heathens celebrating Satan's light should burn in hell. I go to sleep by the burning carbon monofilament of Thomas Alvin Edison's light bulb the way God intended like any good American who had the sense to stock up on them before Obammy's Commie EPA banned them.


...it's funny 'cuz Edison despised Christianity:

Nature is what we know. We do not know the gods of religions. And nature is not kind, or merciful, or loving. If God made me - the fabled God of the three qualities of which I spoke: mercy, kindness, love - He also made the fish I catch and eat. And where do His mercy, kindness, and love for that fish come in? No; nature made us - nature did it all - not the gods of the religions.

Quantum Apostrophe:

TotallyHeadless: LEDs are old, Plasma Lighting is the future.

Yes, like EL lighting was the future in the 1950s...


Thing about LEDs is that beyond a few hundred lumens, you need a whole bunch of them in a large array, where droop and heat dissipation becomes issues. By then, the LED fixtures are no better (in efficiency or light quality) than the Metal halide lamps that are out there already. Plasma lighting has been around, but high efficiency, high lumens plasma lamps are just becoming economically viable and provide full spectrum light that can be used for general lighting and horticulture. In many cases, these lamps outperform LED arrays for high lumens applications.

Time will tell, however, since so much money is behind LED development that the issues with them in general lighting might be solved. But there are technologies out there that could possible be better alternatives.

Quantum Apostrophe: It's surprising how little has changed in the last few decades.


Quantum Apostrophe: A computer? No chance.


Huh? Modern computing is a really farking big thing that's changed since the 50's. Have somebody from the 50's walk down the street of a major city, and see everybody with their face buried in a smartphone. Show them doctors tapping on iPads in the hospital. Have them play a video game.

Yes, there are a lot of mature technologies that look similar, but I wouldn't trust a 50's mechanic to work on a modern car. Pull up in a Volt, or even just a prius, and watch the poor guy cry. A 50's airline pilot would probably be confounded by the cockpit of a 787. Show an engineer from 1950's corning the glass we're using for iPhones, and they'd weep with joy. Show one of the guys working on Explorer 1 the communications satellites we're throwing up on a routine basis. Show him a space shuttle, built with 70's tech and now sitting retired in a museum.

The strides we've made since the 50's are not particularly small.

Was I not clear? This is what I said. Information technology is the one thing we have improved drastically, because fundamentally it doesn't take much energy to represent a bit. All our progress has been closely tied to our capacity to manufacture smaller and smaller devices to work with these small levels of energy.

On the other hand, all our higher energy technologies haven't experienced the same kind of progress. We don't even have Concorde anymore.

But we have people thinking we'll colonize the galaxy.

Sometimes I wonder if I'm not clear enough in my posts. Your response intrigues me. You agree with me, but the tone suggests you think I said the opposite of what I said.

Man On Pink Corner: Little known electrical fact: any diode will emit light if biased properly.



Yeah, but have you ever seen any 1940's or 1950's photographs? They're all B&W. So a properly biased diode back then giving off black light wouldn't have been much use. It wasn't until the world became colourfull in the late 1960's and 70's that LED's gave off visible colour light.

I learned that from Calvin.

Your post came across as saying that we've really only made small improvements to various existent technologies, but then tacked on computers as if it was just a marginal point to the broader picture of technology.

Your post reads, "we've really only made small gains since the 50's, we're just coasting along on the basic designs of the past. Apart from computers."

My point was that computers are a really, really, farking big deal, and that in relegating it to the margins of your post, you're downplaying its importance by several orders of magnitude. We've advanced. Dramatically. As for traveling to the stars, those computers will make it possible. We're in the beginnings of development for a farking warp drive, for chrissakes. We've already started transporters.

Oh, and the Concorde is gone because of economics. It's not like the technology has regressed- we could build a very kickass supersonic jet if we wanted to. But legally, we prohibit going supersonic over land except in very limited cases, and without being able to do that, it's very hard to make it economically viable, especially with teleconferencing.

Your post seemed to really downplay what we have accomplished. Yes, we've been making things more energy efficient and smaller. We've also built a space station or two, gone to the moon, landed a small car on mars by lowering it with a sky crane... Really, what more could you really want?

I was making a contrast. People think because we got better at pushing bits around somehow everything else got better by the same amount. Physical reality says otherwise, hence the 1950s turbine and 1950s computer vs modern turbine (pretty much the same) and modern computer (as you stated, unrecognizable. Hell, even sci-fi authors got it completely wrong only 30 years ago.)

theMagni: EngineerAU: ProfessorOhki: So, break even in the cold months and reductions in power on both sides in the warm

How many people use Christmas lights indoors in July? For the average consumer in the US or Canada, they're used only during the cold months. If you live in a warm climate, yeah, I can see the point, but what percentage of LED Christmas lights are being sold in places where indoor heating is being used during the season in which they're used? My wild guess is at least 80%.

Why the fark would I warm up the outdoors? For big displays, you can save hundreds, if not thousands, on your lighting bill. There's a guy in town that upgraded to 400A service to power his Xmas display before everyone went all LED.

It really didn't come across as any sort of comparison. Just a tacked on, "well, computers have changed, so that's something."

Besides which, I'm not sure anyone has ever thought that. Somebody from the 1850's would have recognized a plow from the 1950's, despite a lot of other advances in that time. A technology matures, and eventually we take it for granted, and it turns into background noise. Do you have any idea how big a deal double entry bookkeeping was to the world economy? It hasn't changed much since the 15th century, but it was revolutionary then, and faded into the background as new things built upon it. So yeah, we've only made marginal improvements to the turbine. So what? We don't advance by radically building on old tech, we advance by inventing new stuff. Always have. And we've invented a hell of a lot of new stuff, and in many cases applied it to the old stuff in really fun ways.

Wook: The All-Powerful Atheismo: Wook: The All-Powerful Atheismo: Wook:
Funny, I was a semiconductor process engineer for 10 years. Our company folded about 2 years ago. I went into Defense. Approximately 7 of my research colleagues took jobs in Solar. Only one of them is currently working. All of the other Solar companies have folded. Solar is good assuming you have cheap labor. Manufacturing in the US is expensive. Excessive regulations and Unions don't help either.

Keep your Wharrgarbl to yourself Sonny, the world ain't unicorns and rainbows!



There are several successful solar companies right in my area. Are the panels cost effective? They have a ROI of something like 10 years right now, so it's debatable. Research is also constantly continuing.

your statement that solar is "total bullshiat" is still retarded no matter what your experiences are in the solar industry.

AKA WHARRGARBL.

LOL Applied Materials (Solar Division), Calisolar, Skyline Solar, Solyndra, Mia Sole......Gone

Research? SVTC gone!!!


You're cute.

And you're an idiot. I already told you there are several successful solar companies in my area. This is a fact.

To claim that "solar is total bullshiat" remains just as retarded as it ever was no matter what companies you cite that have gone out of business.


I stand by my claim that 4 years ago, those in the industry did know it was bullshiat, my colleagues that went into it beforehand knew it. The executives at AMAT pulled out and lost 100s of millions in the process, that was a wake up call to the industry.

Like I said your cute.


You work in tech but can't spell or form a coherent sentence. Sure, kiddo.

I'm calling bullshiat.

SafetyThird:

EL was also supposed to light up homes.


Sylvania sold EL nightlights in the early 60's. I remember my grandma has one when I was a kid growing up - they glowed an weird greenish color and really weren't that bright either.

They also sold fluorescent christmas tree lights in the late 40's, which were really cool too.

Does anyone sell 'all color' LED christmas tree lights yet? The ones I remember seeing recently were only two color.

Rapmaster2000: NOBODY in a first world nation is going to subsidize the manufacture of cheap, low-margin semiconductor parts. There's a reason MOCVD sells the tooling from Germany and doesn't build the parts themselves.


Actually Osram Optoelectronics has a whole bunch of MOCVD tools in their German plants. They grow the wafers in Germany and then ship them to Malaysia to be processed into LEDs. Though to be fair it's mostly paranoia about their IP getting stolen that keeps those tools in Germany.

/ And there are a lot more MOCVD tools in Asia than in Europe and the U.S.

MrSteve007: After years on Fark, I've learned that a fair number of misguided people think it's smart to use incandescents to heat a home. Their COP is about 10% less than the *least* cost effective form of traditional heating. You'll get 3070 BTU (~1/4 ton) for every 1,000 watts worth of bulbs, without proper distribution of the generated heat. In contrast, a heat-pump heats my house with electricity at nearly 4x's the efficiency @ 12,000 BTU (1 ton), using 1,000 watts. My lighting comes from LED.


Yeah, there's one guy on here that insists I can heat my home with incandescents. He's in Kentucky or something so he's pulling it out of his ass since he has no idea what -40F feels like.

The All-Powerful Atheismo: Wook: Rapmaster2000: The libs want us to put all of these LED bulbs in our houses, but did you know that there's more Gallium Arsenide in a single LED than there was on the entire Hindenburg!?

It's true. Look it up.

[o.onionstatic.com image 630x441]

Speaking of which, I worked for a German MOCVD company which designed tooling for GaAs deposition for use in LED manufacturing. The customers (producers of LEDs) were in China. Meanwhile, here in the US Obama's pitching Solar (which we all (in the industry) knew 4 years ago it was total bullshiat). Now we will be giving US dollars to China, which also made Germany rich. Bush's fault? I think not.

Wharrgarbl

China is investing more heavily and successfully in solar than we are, and succeeding quite well. They've managed to make single junction panels quite cheap.

I know. I was there.


That's what happens when you have the government funding companies with the goal of eliminating all compettition. Of course those companies are not currently profiting, but once they're the market monopoly, the prices can be allowed to rise (at least for foriegners).

Well I don't condone many things that China does, and I'm sure the solar company I visited put on something of a show, but it wasn't a totally dirty business. They've got single junction panels up to a 21% efficiency, and they're doing it relatively responsibly (for China).

ftfa: Scientists at the GE Advanced Semiconductor Laboratory were researching a way to create energy-efficient visible light from LEDs. The incandescent lights that we still use today rely on igniting a filament housed in a vacuum to create light. The process is inefficient and only uses 10 percent of available energy to produce light. The rest is lost as heat.

LEDs in the right colour temperature, with internal voltage spike suppression, fused and low/no EMI issues are great on the boat.

They aren't all made alike, however. Learning what's quality is pretty straightforward.

Hint: Having small LEDs, even of the crap "bluey white" type, rigged to magnetic switches and tied into a 9V battery, means you have several years' worth of closet and cupboard lighting in a small, five-minutes of soldering package.

Open door/cabinet/drawer, light goes on. Close, light goes off. Very handy, very cheap and works when the power's off, you don't want to wreck your night vision,you've mislaid the flashlight and when you don't want to wake people up with an overhead light.

Resistance "lights" should be called "heats". Light's just a byproduct. LEDs are the way forward, and yes, there are perfectly acceptable colour ranges and luminosities. You have to get out of the electronic surplus stores to find 'em.

I'm okay with LEDs taking over for incandescents for home lighting purposes. Save the planet and all that.

However, for blinkenlights on appliances, and all the other things we use LED technology for, I insist on the warm, rich glow of a teensy little incandescent bulb. It can be challenging to retrofit appliances that were designed for LEDs, but that's what you have to do if you're a true photophile.

Wow. An 800W space heater is just barely noticeable in any room larger than, say, a bathroom, and it's not wasting any heat by converting energy into useless light.

I also found that three computers running full-steam is still not enough to heat a room. The laptop does make for a warmish lap but that's it.

Well, to be honest, 'incandescent' comes from 3 words: In, Cand and Scent.

'In' refers to the obvious fact that there is glass enclosing the thingy.
'Scent' is there just because.

But everyone seems to forget that 'cand' is a verb from ancient Linear B and is loosely translated as 'to slowly strike a very very tiny match along a future type of metal so that the outer layer burns slowly and brightly until such time as some farker/farkette flicks the switch off, thus unstriking the very very teensy tiny match.'

The extra 'e' was just for sheets and giggles and tho throw off those pesky Linear A-type persons.

Those Linear B'ers, they was very forward thinking.
