An accidental discovery at Vanderbilt University may well be the key to making light-emitting diodes the dominant lighting technology of the century. Up until very recently, the only way to make "white" light was to add yellow phosphors to bright blue LEDs. It wasn't quite right, though, as even the best "white" LED retained a blue tint. This week, we got the news that a chemistry grad student at Vanderbilt has stumbled on a way to make broad-spectrum white LEDs using quantum dots -- and in doing so, he may well have kicked off a revolution.

First off, these things are ridiculous, I work as a HAZMAT certified Designated Responder for the largest shipping company in the World, and our number one, worst case scenario in our hubs involves "Mercury!" One gram of the substance released on our premises will shut down a building at a cost of $35,000.00 an hour, and require a full building cleanup to prevent any exposure to the workforce. This stuff is very dangerous, causes many problems in the human body.
