A Glow In The Dark... Lightbulb.

from the amazingly-redundant-ideas dept

Instead of lighting candles when the power goes out, why not just invent a lightbulb that glows in the dark? The bulb takes 15 minutes to charge and then glows for up to 24 hrs. I wonder what do you do when you actually *want* to turn off the lights....

    Fun with lasers

    Oh, you could always shine a green laser on a traffic signal and cause major mayhem at night...

    Would have been useful last week

    Actually, that's pretty damn clever. Although I'll wager that the light can't be that great from it.

    Sounds like its really only for emergency lighting though. Might make a neat novelty gift.
