Too late. Incandescent bulbs will soon be illegal.

From that article:
"The pulse lasts a mere femtosecond, and delivers as much power as the
entire grid of North America into a needle point size spot."

Huh? I think they left out one of the units or something, and if they
didn't I don't see how using that much energy to modify the filaments
could save energy on a production scale.

Read the comments below the article: lots of sloppy "science" in the text.

I forwarded this article to my pointy-headed scientist friend. Curious
to see what he has to say about this.
