Incandescent Bulbs Return to the Cutting Edge

Earlier in the article they said that a 70 watt bulb is now giving off the same amount of light as an older 100 watt bulb. They said it was 30% more efficient.

Later in the article they say:

> David Cunningham ... [has] develop[ed] a reflective coating and fixture design that he believes could make incandescents 100 percent more efficient.

100% more efficient? Zero power input? Me must really be giving 110% to acheive results like that.
