Researchers at the University of Illinois got a bright idea. They developed a form of lighting that's more efficient than standard incandescent bulbs. And it's lighter and thinner than current fluorescent lights, which require a ballast and glass tubes. The diagram above shows how the researchers' aluminum foil-based "microcavity" plasma system works to produce light.
The researchers say their lighting system would look like a luminous, flat screen that could hang on walls in residential and commercial locations. The technology would even allow for curved and flexible versions of the lights, which could fit a wide … Read more
