White LEDs for a Brighter World

deepfry writes "CBC radio today featured an interview with Dr. Dave Irvine-Halliday, an engineering professor at the University of Calgary, who's developed a home lighting system for the developing world using a combination of white LEDs, pedal generators and rechargable batteries. This type of "pico-power" can make a huge difference in the lives of villagers in rural areas where being connected to a power grid is not an option and probably never will be. Read about the Light Up the World project and make a donation."

    Forget white LEDs, give me bright blue ones. The power on light for UV Networks web appliance is a bright blue LED. I think I will buy one just for the cool blue LED. I need these blue LEDs on all of my puters!

    ..do these LED lights interfere with 2.4 GHz 802.11 communication?

    I suppose if you can't get connected to a power grid, you probably are going to have a hard time getting wireless Internet serverce, making this a non-issue. But still, let's not be short-sighted!

    It will be great to finally be rid of the antiquated incandescent bulb. LED has been a long time coming, and I'm sure all of us are excited about the promise of this sweet new tech.

    Not to mention, I need a nice Gandalf wallpaper (well, okay, maybe not "need"...). I want a close-up where he looks pretty stoned, like in most of the movie. I would prefer his pipe to be featured, if at all possible, and no writing (titles, copyright notices, etc). 1024 or larger, please. I know someone reading this has the perfect image for me!

    I'm of the opinion that the light bulb filament has been as like a Chain unto Humanity, even as fluorescent bulbery has been a Poison'd Gas which Chokes at Our Throats.
