Graduate students still seem to be of use in the world. One getting an education from Vanderbilt University found a way to make LED lights brighter than ever. Comparable to a standard 60 watt bulb and emitting a similar color of light (warm, yellow-ish, perfect to read by). Read the article to see how.
The cool part, aside from the potentially massive decrease in energy costs, is that the technique could be applied to tons of normal items, not just an LED. A picture frame could be made to light up around the picture. The centerpiece for the family dinner can also light the table as you eat. The walls of the inside of your fridge could light up instead of the bulb.
The ultimate blend of form and function, and it came from a geek. Martha Stewart is going to drool all over this one day.
