Engineering a Better Bulb (Popular Science)

This is an interesting article that talks about the inefficiencies of modern lightbulbs, and suggests a new alternative. They estimated that we can save about US$35 billion dollars here in America by changing our production away from the traditional tungsten lightbulbs to a newer zinc oxide type bulb.

Here is an excerpt from the Popular Science article: "The lightbulb has remained virtually unchallenged since Edison invented it more than a century ago, but now scientists believe that zinc oxide-the same chemical that keeps diaper rash at bay-could provide a much-needed alternative to the inefficient lights that dominate our homes."
