Scientists Trap Light In Nano-Soup

An anonymous reader writes "Physicists at the Bhavnagar University in Gujarat, India have trapped light in a nano-soup concoction. The chance discovery could pave the way for lab-on-a-chip devices for processing optical information. As of now there is no theoretical explanation for why the fluid has the effects it does on laser light."

Probably not: you need to keep a magnetic field of an exact strength around it to hold the light. So you still need batteries or some such to maintain the field. (You'd want an atrificial field so you can choose the wavelengths of light to capture, and because it is easier to remove uniformly.)

There is probably also a maximum amount of energy you can store per unit volume, though I'd guess they don't have that worked out yet.
