White LEDs for a Brighter World

Posted by michael on from the daddy,-what's-a-light-bulb dept.

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."

    Can the editors of slashdot please disclose how many of your staff are minority? I emailed my resume and never got a response. I am also a black female... Coincidence? I think not.

    I can see it now: Some third world family of 12. Dad says to the 3rd kid "Okay, your the dumb one so the rest of us can learn. You get to spend the rest of your likfe riding the exercise bike while the rest of us learn to read."

    Don't feel bad for the "dumb kid" though, he will go on to win international biking compititions, while the rest of the family trys to compete in the rat race with millions of other people.

    Our village elders agree with you. I'd say more, but we're on a hunt for witches and evil spirits right now, and the others tend to get suspicious if I don't join in...

    using a combination of white LEDs, pedal generators and rechargable batteries.

    Nothing innovative about this, the Professor was using pedal generators to power ALL KINDS OF THINGS while shipwrecked on Gilligan's Island back in the late 60s / early 70s.
