Light Emitting Fibers.

It seems that scientists have created an ultra-thin fiber that emits light from tiny spots on its surface. The spots are only 250 nm across, which makes them smaller than the wavelength of the light they emit, which is 600 nm. Personally, I had thought there was some sort of physics rule against that, but I guess I was wrong.

The article also says that, when fed 100 volts of electricity, the tiny spot glowed strongly enough to be visible to the naked eye. That, to my mind, indicates a very high efficiency of conversion of electricity to light. They also say the fibers could be woven into cloth, so that we could have electroluminescent clothing. Its about time.

...Though I'd prefer my electric shorts to run at a lower voltage. For various reasons.

Normal operating voltage is expected to be 3-5 V, and nano-amps.
