In last week's column I examined a fairly unusual local power source: the Northfield Mountain pumped hydropower system, which is used for "storing" electricity--by pumping water uphill. This week we'll take a look at a very different power-generation system that's even closer to home: the landfill gas power plant at the Windham Solid Waste Management District (WSWMD) facility on Ferry Road.

whir... whir... whir.. whir... CLUNK! It finally worked... after decades of catching nothing but birds and bats, while making a small amount of electricity as a byproduct, the international effort to catch a UFO netted its first victim.

Light-emitting diodes, better known as LEDs, are all around us--those little red or green indicator lights that blink at us from our stereo equipment, most new traffic signals, and virtually all new exit signs in commercial buildings. And if you've been to Times Square recently, you've seen way too many LEDs being used for advertising! We've all seen colored LEDs; what's new is the use of white LEDs for indoor lighting.
