Hydrogen-powered vehicles are needed so we don't depend on fossil fuels (a limited resource), and to reduce pollution. You still gotta replace the batteries or fill the tank, tho. :)

And guess what our primary source of hydrogen is right now: natural gas. More economical and energy efficient than extracting it from water via electrolysis. Either way, it all goes back to traditional energy sources.

Re:'Cause.. (1)

Telecommando (513768) | about 11 years ago | (#6784739)

It was my understanding that most of the world's hydrogen was produced by cracking it out of natural gas, which requires energy. So you end up using fuel to convert one type of fuel into another type of fuel at a net energy loss.

I may have been misinformed but that's how I remember it.

s20451 (410424) | about 11 years ago | (#6784749)

Hydrogen is not that explosive. In many ways a hydrogen powered vehicle would be safer than a gasoline powered vehicle. Since hydrogen is a gas, it tends not to stick around in one place once it leaks. It also tends to be less volatile than gasoline. Check out this page [fuelcellstore.com] .

Most people assume that hydrogen is disproportionately dangerous because of the Hindenburg disaster. The fact is that if gasoline powered engines were invented today, gasoline is volatile enough that they would be considered too unsafe to be approved.

OK. So how much time are you spending changing light bulbs per year? And was the total time spent submitting this news story longer?

To be honest I don't think that changing light bulbs is a major household time sink. (Different story of course for people who deal with traffic lights, and hence the move to LEDs). I must spend minutes per year changing light bulbs, I waste far more time replying to /. articles complaining about people worrying about optimizing the wrong sort of time wasting activities.

The problem with flourescents is the ballest gives off a hell of a lot of EMF "noise". For those of us who like to us X10 to switch on and off lighting, flourescents cause nothing problem problems.

Give me a clean, quiet, low heat LED bulb and I'll buy it even if it is $25-$40 a bulb..

Re:Heard of Flourescence? (4, Informative)

jandrese (485) | about 11 years ago | (#6784727)

The problem with the flourescents on the market right now is size. All of the screw in varieties have big fat bases that interfere with a lot of lamp designs. The 75 watt equivelent and higher bulbs are also longer than traditioanl light bulbs, which causes problems in globe lamps and anything else where the bulb must fit into a small area.

On the other hand, the modern bulbs are really good about lighting up right away, not flickering, and not dying prematurely--hopefully (unlike some of the early screw type flourescents).

One word of advice from me to Slashdot: Don't buy the "Lights of America" brand, they're nothing but trouble.

Well, I'm damn sure Color Kinetics isn't getting any of my money. From the article:

The company holds 19 patents related to the control of LED lighting systems, and has filed for more than 100 additional patents. "We spend about a million dollars a year filing patents," says chief executive George Mueller. The company has two full-time patent lawyers in-house, and also works with the Boston firm of Wolf, Greenfield & Sacks.

And:

It'll be interesting to see whether Color Kinetics can exact a licensing fee from anyone who blends colored LEDs. Says Simms: "We haven't invested the fortune that we have in intellectual property without planning to defend it."

I still hope electric cars will eventually win out over fuel cells....if someone can make an extremely high density battery or capacitor, that might make it come true.

As far as light bulbs, I've been replacing mine with flourescents as they burn out. I've got some flourescents that have been going on four years now without a failure. They are only a couple bucks now and they use a lot less energy.

Hyrdrogen "clean" fuel is a misnomer...since the hydrogen you get from one of these California H2 stations is made from natural gas, and not electrolysis. You end up using fossil fuels just the same. Maybe some day we can switch to from-water hydrogen...but where are we going to get those petawatts of electricity to do that? Nuclear power? We can't agree on a place to get rid of our waste. Solar? It takes energy to produce those acres of panels, and you are displacing wildlife in the process. Microwave from satellites?

Hydrogen Power (1, Interesting)

HydroCarbon10 (40784) | about 11 years ago | (#6784681)

Wait, so if you don't fill up your hydrogen powered vehicle, where does the energy come from? Better yet, explain where the hydrogen will come from to power your vehicle. Don't become enveloped in the promise of hydrogen power. Without an efficient way of extracting hydrogen that doesn't use fossil fuels as the underlying energy source for the extraction, the promise of hydrogen power is a sham. If the Bush administration says that hydrogen fuel will be our savior, perhaps that's a clue that you should educate yourself on where such a fuel would come from. Putting money into hydrogen is wasteful without clean sources of energy to make extract the hydrogen. You might as well just keep burning oil because hydrogen extracted by a process utilizing fossil fuel will only end up costing you more money.

Use Compact Flourescents for Lighting! (4, Informative)

tbmaddux (145207) | about 11 years ago | (#6784694)

Compact flourescent bulbs produce the same light level (in lumens) and consume 25% of the power (in watts). They also last tens of thousands of hours as opposed to hundreds of hours. And you can buy them today for 1/10th the price quoted by John Fan in the original article.

LEDs have their places where you need something bright and compact that can be turned on and off quickly. I like the new LED flashlights, brake lights, and street lights. But use flourescents for lighting, please, and use them today.

I have been hearing this story for the past 20 years, along with the death of magnetic storage media. Light bulbs are so damned cheap that it is very difficult to convince people to replace a $0.20 part with a $20.00 one, or even a $2.00 one, despite their energy inefficiency. Another problem: I purchased a few of the high efficiency screw in florescent bulbs, (despite their costs)and as soon as I installed it my wife commented that they were ugly, so they have all been relegated to the basement.

It's already happening (1)

porkchop_d_clown (39923) | about 11 years ago | (#6784724)

Lots and I mean lots of tractor trailers are using LED tail lights now. Admittedly, the wattages are a lot lower and red is cheaper than white, but take a look at the next several trucks you get behind - at least some of them will have the tell-tale "pixel pattern" that comes from replacing a bulb with a grid of jumbo LEDs.

In seriousness, this would be a good idea (1)

EmagGeek (574360) | about 11 years ago | (#6784700)

if the manufacturing costs could come down. We waste TONS of energy on those little heaters we call light bulbs. Most of the energy that an incandescent bulb dissipates is done so in the form of heat. LEDs are indeed incredibly efficient in comparison, last longer, and the whole bit. The only problem is cost.

I think something to think about, however, is the effects of monotonic spectral emissions on aesthetics. Lightbulbs more or less follow Wien's Law which states that an object of a certain temperature emits energy along a continuous spectrum, with the peak at 0.0029/T(kelvin) nanometers. LEDs are monochrome or polychrome (in the case of white LEDs) so you get one or a few colors, but not a continuous spectrum. I wonder what effect this might have on people's comfort in their surroundings, psychology, or whatnot...

Once the cost comes down, we might get to study these results... Of course, with all the jobs and factories going to India, that might not be a problem after too much longer...

The thing is... (4, Insightful)

Sheetrock (152993) | about 11 years ago | (#6784703)

If you do the math, the regular old light bulb is still most efficient overall when compared to fluorescents or neobulbs. The amount of energy, resources, and pollution that goes into something has to be taken into account if you're really looking at reducing your impact on the environment.

Additionally, you can't go wrong with nuclear power if you're looking at least polluting power sources. Many people look at solar as if its some sort of panacea, but the amount of energy that goes into making a tile is far more than you'll ever get out of it -- turns out that at the end of the day the thing everybody's been complaining about is the best option because all the pollution is contained.

The problem is cost (5, Insightful)

toddestan (632714) | about 11 years ago | (#6784708)

The thing is, no matter how cheap they make LED lightbulbs, I doubt they'll ever get as cheap as the incandescent bulb, as the incandescent bulb is just plain out cheaper to make as it is much more simple. Therefore, the Wal-mart crowds will still buy the standard bulbs for years to come.

What they should do if they want people to adopt these new bulbs is make it so all lightbulb packages have to display the average cost of the lightbulb over its lifetime. People may see that the LED or flourescent lights sitting on the shelf right now cost a lot more and don't buy them, but I bet they will when they see on the box that the bulb over it's lifetime costs a fraction as much in electricity used.

I guess that answers the age old question... (1)

But this is still a looooooong way's off, farther it seems than hydrogen-powered cars:

"You could replace a 100-watt light bulb with a 60-watt LED, and get the same brightness," says John Fan, chairman and founder of Kopin Corp., a Taunton company that makes LEDs. "You'd save 40 percent on power, but it would cost about $100. We need to bring that price down."

Electrical issues (4, Interesting)

jgerry (14280) | about 11 years ago | (#6784718)

I have always suspected that many electrical issues, including frequently blown light bulbs, are caused by dirty power. What I really want isn't better light bulbs, it's better power. Everything would operate better and/or longer if the power coming out of the sockets wasn't so random and dirty. Ever look at a standard 120V AC on an oscilliscope? Nasty.

Does anyone know of a whole-house solution for providing clean, voltage-regulated power to an entire house? I probably have $50K+ of computers, music equipment, home theatre, etc, and all of it would be better off with clean power.

We have whole-house solutions for water filtering, air filtering, so where's my whole-house solution for clean power (and maybe even whole-house UPS?)

We already have a good lightbulb replacement... (3, Insightful)

cmowire (254489) | about 11 years ago | (#6784728)

Florescent lights work just fine, are more efficent (especially if you want white light) than incandescent bulbs or LEDs, and are cheap and well developed in comparison.

They've got a whole spectrum of colored tubes using the same technology as they use to make neon signs, if you so desire.

The only thing that you get with LEDs is the ability to get small amounts of light from very small amounts of power.

They are great for microlights and flashlights and medium-sized jumbotrons and a few special purpose applications where normal lights just won't work. The LED manufacturers are getting sick of just making indicator lights, so they are trying to push their new toys as much as they can.

Fluorescent lightbulbs anyone? (1)

2nd Post! (213333) | about 11 years ago | (#6784735)

Gonna read the article now, but a brief scan of the comments brings up some strange math...

Replace a 100W lightbulb with a 60W led bulb? Or a 40W led bulb?

How about *right now* replacing a 100W lightbulb with a 25W fluorescent lightbulb...?

Hydrogen - The future of Buzzword Energy (2, Interesting)

ka9dgx (72702) | about 11 years ago | (#6784754)

Hydrogen is often used to conjure up visions of a clean future. If only the greedy oil companies would see the purity of the vision... blah blah blah...

The fact is that you need energy to produce hydrogen, and that energy is probably going to come from either Coal, or Natural Gas. The end user thinks their helping the environment, but what really happens is that the production of a carbon exhaust is moved back in the supply chain. The amount of Hydrogen produced by a renewable source in any reasonably short time frame (20 years) is going to be almost negligible.

The Hydrogen Future seems too good to be true, because it is.

Time to replace white light (1)

GillBates0 (664202) | about 11 years ago | (#6784758)

Two things that annoy me are filling the gas tank and changing light bulbs. It's time we did alot less of both.

Another thing I find annoying is white light. I am sick and tired of white light. Who the heck needs white light at night. About 12 hours of white light a day is more than enough for me.

I, for one, would find the red/green light emitted by LEDs a welcome change.

Can't we make our own LED light bulbs? (1)

azav (469988) | about 11 years ago | (#6784770)

That report states that personal LED light bulbs would be $100 each. That seems rather high.

Couldn't we enterprising slashdotters come up with our own LED white bulb? And publish a how to?

I'm thinking take 3 white LEDs, immerse them in a plastic or epoxy mixture to diffuse or scatter the light and apply some circuitry to allow them to work in a bulb socket and there you go.

Anyone care to help out or provide info?

Hydrogen cars don't stop you having to fill tanks (0)

Anonymous Coward | about 11 years ago | (#6784773)

Hydrogen cars just have a hydrogen tank that still needs to be filled.

If you want to avoid filling a tank, what you want is a battery electric car. Then you're not filling a tank, but filling (er.. charging) a battery. While that doesn't seem much different (you're still filling something), charging the battery can be easily integrated with getting home, plugging the car in, and closing the garage door.

Will these be permanent? (2, Interesting)

Lord_Dweomer (648696) | about 11 years ago | (#6784776)

So granted I didn't RTFA.....but lets take a hypothetical situation. Lets say its possible to create a light that doesn't need to be changed EVER. Or more realistically, 100 years. Lets say its dirt cheap to make too. Would such a light be sold? Or would the patents simply be bought by existing lightbulb companies to kill off an invention which could utterly ruin their business model?

I also wonder if any company who invents these lightbulbs will not build in some sort of artificially short lifespan so as to have an increased revenue as people have to continually buy more.

Right now: compact fluorescents (1)

autechre (121980) | about 11 years ago | (#6784777)

I can go to IKEA and get cheap compact fluorescent bulbs which fit in "regular" light bulb sockets. Even the 11w and 20w variants can be quite bright. I'm not sure how long they last, because I haven't replaced one yet.

Yes, fluourescent lighting isn't as nice aesthetically as incandescent lighting, so I still have a full spectrum incandescent in my bedroom (right next to the lava lamp). And I also can't replace the incandescent in that cool 3-brightness touch lamp in the living room (but again, I prefer to only use fluorescents in areas like the bathroom, kitchen, doorstep, hall, etc.). I'd be interested in finding out how LED lighting "feels" compared to current technologies, and also how the spectrum stacks up (wouldn't it be great to save on electricity and counter SAD at the same time?)

Anonymous Coward | about 11 years ago | (#6784778)

to change a light bulb?

1 to make the press release
2 to dump stock after the market reacts
3 to claim licensing fees on the first 2.

Note that the bulb actually never gets changed.

Yea more patents to be abused (2, Insightful)

PostConsumerRecycled (653177) | about 11 years ago | (#6784785)

The company [Color Kinetics] holds 19 patents related to the control of LED lighting systems, and has filed for more than 100 additional patents. "We spend about a million dollars a year filing patents," says chief executive George Mueller. The company has two full-time patent lawyers in-house, and also works with the Boston firm of Wolf, Greenfield & Sacks.

Great!! I'm not against the concepts of patents, but this just seems crazy, this can only hinder innovation not promote it.

overly broad patents + full time patent lawers != good business

Computers that change colors?? (1)

eaglebtc (303754) | about 11 years ago | (#6784793)

One situation to watch: Apple Computer recently filed a patent application for a computer whose exterior would change colors, apparently after Color Kinetics had demonstrated their technology to Apple. "It covers a lot of our technology and a lot of patents we hold," Mueller says.

(Imagine that, though: a computer that would glow different colors based on how much of its processing power was being used. When it turned red, you'd know that a crash was imminent.)

So based on the above statement, if I run video editing software, or defrag my hard drive, or even run CPUIdle, then the computer will glow hot red, and therefore a crash is imminent.

Cool!

In the first paragraph, it looks like Apple is trying to pull a Taco Bell [msnbc.com] .

Fluorescent Replacements for Filament Bulbs (1)

nurb432 (527695) | about 11 years ago | (#6784797)

They are a bit more expensive, but last for years.. ( literally years, I've had mine running for 5 years now.. only one that's blown is the one the cat knocked over, and shattered..

They also save power, and have many many sizes to fit most any lamp.

LED traffic signals (5, Interesting)

frostyboy (221222) | about 11 years ago | (#6784803)

I must say that Color Kinetics gear rocks. Their color-mixing LED arrays not only look cool, but are a neat toy to program for fancy light shows.

Also on the LED front, the city where I currently reside (champaign, IL) recently passed funding and a proposal to replace all of the old incandescent traffic signals with LED arrays. Should cost a lot of money originally, but will save big on electricity bills in the long run. Here is an interesing EPA EnergyStar paper [grrn.org] talking about the potential energy savings that cities can get from this technology -- 1 Million kWh and nearly $70,000 per year per 100 intersections! Also, LED based traffic signals are (IMHO) easier to see both at night and during the day.

One complaint from a study [uiuc.edu] is that the green traffic lights are actually too bright.
