Light Bulbs Soon to Be Dinosaurs

This is vaguely interesting.

From USA Today:

If a time traveler from a hundred years ago were to visit a home today, much of the technology would be completely alien. The television, cordless phone and computer would probably leave him flabbergasted.

But on seeing a light bulb, he might say, "Ah! Here's something I recognize. A few of those grace my home, too."

If the visitor comes back in 15 years, the fruit of Thomas Edison's bright idea may be gone. The likely replacement: light-emitting diodes, or LEDs.
