Project Porchlight [via mefi projects] is a volunteer-based, not-for-profit group that aims to deliver one free energy-saving compact fluorescent light bulb to every household in Canada. If successful, the resulting reduction in pollution from energy saved will be the equivalent of taking 66,000 cars off the road.

The end of the light bulb? E. Fred Schubert, a professor at Rensselaer Polytechnic Institute "claims to have invented a 99-percent efficient reflector that promises to speed the replacement of light bulbs with LEDs." According to researchers, this could happen within the next five years. The current prototype is bankrolled by the ARPA and The National Science Foundation "recently award Schubert's team a $210,000 grant to create in three years a commercial version of his patented omnidirectional reflector."

"Schubert claimed that lighting accounts for 25 percent of U.S. electrical energy consumption. Since white LEDs emit more light per dollar and generate less unwanted heat, they are potentially a major energy saver." (see EE Times link)

Meanwhile, some of the oldtimers seem to be pretty refractory.

The end of Edison's greatest invention. All good things must come to an end, I suppose. This one lasted longer than most of the 19th century's great inventions -- like the steam locomotive.
