The twirl of a lightbulb
I'm reflecting on lightbulbs. Or, more rightly, I'm looking at the reflection of lightbulbs on my laptop screen. The bulbs twist in a circle. Round and round. The newest, energy efficient style. The light that is emitted comes in cool white and a warm yellow -- different strokes for different folks! In the old days we used incandescent lighting. No ballasts, excited gases or twisted glass. Just a globe of glass with electified wires that glowed brightly, casting light throughout a room. What will be the next step? In 1975 I stayed overnight at an engineer's house. He was working on the newest thing -- halogen lighting. If I were to stay overnight in 2007, what would be in the works? Perhaps a way to gather sunlight into a box which slowly emitted light. Or maybe lighting triggered by the warmth of a touch and maintained by perpetual motion. OR . . . perhaps two stones sparking a cone of grass -- and capturing the smoke as a preservative. Oops -- maybe that's been done before??
