We use LEDs (light emitting diodes), which are more expensive, but the light is nicer, too.
Anyway, always love to see what those clever Brown students are up to: they invented a cloth to mop up the mercury after you break your CFL. Doesn't make me feel better about compact flourescents, but I admire their cleverness.
p.s. the secret mercury absorber is selenium--make sure you get enough in your diet! Brazil nuts are one of the natural sources with the highest amounts.

Brown University researchers have discovered a nanomaterial that can absorb the mercury emitted from a broken compact fluorescent lamp (CFL). The researchers, led by Robert Hurt, professor of engineering, and engineering student Natalie Johnson, have created a mercury-absorbent container lining that can be used commercially. The packaging invention, for which Brown has applied for federal patents, would relieve a major concern with CFL use and comes as CFL sales are projected to skyrocket.
