Let there be light!

NPR article on LED technology

"People were spending about $38 billion a year on kerosene. The poorest people were spending the most for the worst. You and I complain when the cost of our flip-a-switch electricity goes up to 15 cents a kilowatt hour. The people using open-flame kerosene lighting are paying on the order of $80 a kilowatt hour. Again, these are the poorest people in the world."
