standards for lightbulbs that it has been assumed, until recently, that
it would kill off the incandescent bulb. Instead, the law has become a
case study of the way government regulation can inspire technical
innovation. For example, new incandescent technology from Philips that
seals the traditional filament inside a small capsule (which itself is
contained within the familiar bulb). The capsule has a coating that
reflects heat back to the filament, where it is partially converted to
light. The sophisticated ($5.00) bulbs are about 30% more efficient than the
old-fashioned ($0.25) kind, and should last about three times as long.
So they are less economical than compact fluorescents, but should emit a
more pleasing spectrum, not contain mercury, and, one supposes, present
the utility company with a more desirable power factor."

What ever happened to microwave lighting that I saw on TV over a decade ago that was going to kick ass???
and where is my flying car and VR sex slave.
o.. and why does my car from 1997 get the same MPG as all the new ones that don't have massive arrays of lead acid battery's?
The light bulb is lame. I want my damn sharks with flipp'en lasers and you need to get off my LAN son....

On the other hand, mercury is toxic forever. It never, ever, becomes safe, no matter how long you wait. When the glass breaks it'll poison you just as well in a million years as it does today.
No, no, you're missing the beauty of it. Instead of using normal mercury, there should be a mandate for light bulbs to use mercury-194, which has a half-life of 444 years. A perfectly-manageable timeframe for waste storage.
Another cool thing is that the bulb lights up without even being plugged in. It actually generates energy rather than consuming it.
But here's the really cool thing: according to Wikipedia, Hg-194 decays by electron capture into Au-194. That's right, in 400 years half of the mercury in your light bulb will have turned to gold. Replace all of your household lamps with Hg-194 compact fluorescents, and you won't even want to throw your burned-out light bulbs away in the first place!
It's amazing how many seemingly-intractable environmental problems would go away if people would just think outside the box a little.

Could you edit that wiki entry and add:

Sunlight is not yellowish
Sunlight also contains a whole lot of radiation. Personally, the last thing I want is a miniaturized sun in my lamp.
