But for the moment if you want highest efficiency you're stuck with lots of blue in the light and a "cold" feel.
No, you're not. LED-bulbs are availabe in daylight and warm-white. Though the warm-white may have a greenish tint, just like some cheap CFLs. But that will go away very fast when the turn-over accelerates and companies see money in opimizing the fluorescent inside the LED.
White LEDs do not contain highly toxic substances. Infrared ones do contain arsenic, but are well-capsuled and robust, i.e. break-resistant. CFLs do contain mercury and break rather easily.
$40 for 19 years sure is nice, but who wants to make that kind of investment, assuming there's 10+ bulbs in the house to replace? I'd rather pay $4 for a 6-pack and have to replace them in a few months.
Making a one-time investment of $40 and getting a return of $29 each year for 19 years gives you a total win of how much? I'm leaving that calculation as an exercise for the respected reader.:-)
I'm wondering why no investment bankers have thought about that, given the fantastic return...
Dimmable LED-bulbs are no real problem, given that they have to use a regulated power supply anyway. See EarthLed.com, they have dimmable LED-bulbs and also have a LED-bulb to replace a 100W incandescent, but it is not dimmable (yet).
While I wouldn't mind using LED as replacements when the existing CFL wear out, particularly if they are less toxic when discarded, what I really need is a replacement for halogen small US base and bayonet, along with a few "candelabra" small base bulbs. Dimming would be a plus.
Anyone making those yet?
Hmm, don't know about your socket requirement (I'm not US-based), but have a look at EarthLed.com, they have replacements for 10W halogen bulbs as well as most CFL forms. And yes, they are dimmable.
I'd recommend reading "Starship Troopers" by Robert Heinlein, which covers some interesting problems regarding exoskeletons used in combat. The solution of course is to not amplify the soldiers strength unless needed. The suit should simply move with the body in normal situations and only ampify in extreme situations, when the soldier exerts extreme force.
o What is the qualification process for earning "trust"?
Hmm, that's easy. As all they want to do is to check for slanderous or praising-without-merrit articles, anyone who is unrelated to the author should do. I think that slashdots moderating system is a good example how wikipedia could work without needing to create a two-class-society. Just hold all changed articles until two or more randomly selected people have voted it ok. The catch of course is how to select those people, you need a constant and large followership, which is somewhat contrary to how wikipedia works.
Instead of putting athletes into two groups named "male" and "female", put them into multiple groups based on hormone levels, muscle mass, body proportions and intellectual capabilities. And then merge "normal" olympics with special olympics an paralympics...
How can you convert construction costs into figures that amount to something-per-year or -per-kilometer?! You have to assume a life-time, but how long is that? One year? Ten years? A thousand years?
For cars or busses or trains or aircraft you can do this, because those things have a defined lifetime after which they are scrapped.
But you cannot do that for roads or rails, because they won't be scrapped and rebuild anew, they will be maintained and reworked! So the construction costs are one-time only and cannot be included in the figures.
The sad truth is that most American cities are ill-suited to public transportation at the fundamental design level. You can't hack an effective and economic public transportation system onto them, and taking a wrecking ball to three-quarters of the American landscape would be expensive beyond belief for a very modest benefit
aww, I have done that in simcity several times, you just need the infinite-money-cheat for that...
Car manufactures want this. Have you ever seen the wire bundles in cars? If the lights had network address all you'd need one just ONE wire ad the switch on the dash would broadcast the "turn on" command.
This already exists, it is called a CAN-Bus and is designed to provide much more safety than the IP protocol. You don't want your network stack to need to resend a packet if that packet is directed at the brakes...
I will go out of my way to pay for indie music, when I find a band I like. has anybody mentioned magnatune.com? now THATS a way to sell music: you can listen to it for free, without restrictions, you can determine how much you want to pay for it (within limits) and 50% of what you pay goes directly to the artist, there is a whole bunch of formats available and you are asked to share the download with up to three friends.
What I would like to see, however, is a national TV broadcast of this kind of speeches. That would be a heavily profitable investment on education. Yes, that would be good. Also, they are only providing a windows media version or PDF. Instead they should upload the videos to youtube for maximal coverage...
Then ask yourself, do you really want to give the government the ability to ban books? not to ban arbitrary books, no, but what about a book about a child molester describing his heineous deeds with deep satisfaction and thus depicting his doings as normal. i want a ban on such a book.
If fictionally depicting someone being raped or abused is a crime then surely horror flicks must be banned as well. Oh and the Die Hard movies too because they can be training tools for terrorists. it depends. what should be illegal IMHO is depicting crimes as normal as is done in rape-flicks. but as long as the film is about FIGHTING those crimes (like most horror movies and die hard as well), it is OK to depict such crimes.
If it's not illegal to do, then it shouldn't be illegal to represent digitally with a bunch of 1s and 0s. yeah, but that is the point: rape is illegal, so the depicting of rape as a normal doing should be illegal too...
I just don't get this. Why the fsck is any government getting into what a person can look at? because what you watch today influences what you do tomorrow. it is as simple as that. humans learn by imitating other humans. insofar it is a good thing if public discussion start about what is appropriate to watch and what not. in the case of rape-movies, yes, i find them inappropriate. as well as all other flics depicting brutal, inhumane behaviour as normal.
oh, and before we start a flame war, i said "influences" and not "makes you do". watching a brutal murder on tv doesn't normally turn you into a murderer. but watching only slasher movies can build up a fantasy world where you consider killing another human being as a feat worth doing... as has happened with three teenagers who had tortured a handicapped classmate and had intentions of killing him.
Yes, that's right. Copyrights exist to cause authors to create and publish their works so that the public domain can be more enriched than it otherwise might be. However, if an author in country A simply doesn't care about -- i.e. wasn't incentivized by -- a copyright in country B, then why would it make sense for country B to give him the copyright? If it was important to the author, he would pursue it. If it is not important to him, he'll ignore it. Now this is right if you exchange "author" with "multinational corporation". But if you exchange "author" with "you and me", it doesn't hold up anymore.
This system clearly favours those with a lot of money at their hands to generate even more money. So yes, this is how America works. And where its problems stem from...

White LEDs are not based on gallium arsenide as infrared LEDs are, they use indium gallium nitride which is non-toxic.
There are dimmable LED-bulbs available, have a look at http://www.earthled.com/

Wow, replying to someone with a quote that's on the page they linked to, but providing a new link. That's probably a new low even for Slashdot.
Wow, flaming somebody for "restating something obvious" when the "obvious" is hidden in an img-alt-tag... that's typical for Slashdot. :-)
Chemistry?? I think you mean Physics. I can hide from your stamp collecting at the center of a black hole, if need be.
I think you mean mathematics.
You of course are aware that Physics is to Mathematics what sex is to masturbation. But hey, given this is slashdot...
