We could be soon enterting a world with no more neon. Wake Forrest phyics professor David Carroll has just come up with a better way to replace energy-wasting light bulbs, using plastics and nanotechnology. And he's bullish about buy in from consumers.

When you factor in the energy savings, he believes they could be 25 percent less expensive than bulbs of the Thomas Edison variety.
