OT: Here we go again......
Guy,
Re: (One poor person thought Cree was going to replace the incandescent light bulb!) Ummm, that might have been me.... hehe.... Actually, GE through their subsidiary Gelcore (in cooperation with Emcore) is working on just such an LED solution. While the efficiencies are not at a level where they are practical vis a vis the most efficient HID or fluorescent bulbs, they certainly are a very competitive at this point with the highly inefficient incandescent bulb. The first commercial lighting products using LEDs are in special applications such as display signage, like the jumbotron type displays at the political conventions this summer and the other economic use for long-lived LEDs is in traffic signals, where the savings in the cost of maintenance, not to mention increase traffic safety and convenience for the driving public makes the LED a 'brillian' solution.
So, don't be too disparaging. A fun kind of place to take a peek at is www.compoundsemiconductor.com. It may not alleviate you of all your skeptical tendencies, but it will probably excite you, like it did me to the tantalizing prospects for the future. And yes, Joanne, who is the webmistress and editor also believes as I do that incandescent light bulbs are presently an archaic relic and will soon be replaced by far more intelligent solutions. So there. :))
You're right about the CREE thread, same with AVCI, zealots are such a bore.
I'm getting the evil eye from the librarian. Apparently she's got a life.... so to be continued..... QM can be reversed? ohmigod... :))
