Please log in for more thread options examine the circuitry and to see what component emitted the thick smoke cloud when the GE bulb failed. I was thinking of making a jig from a 2 by 4 scraps with two v's cut so that I could rotate the base of the bulb around against a 1/2" Dremel cutoff wheel at a fixed distance, sort of like a can opener. The N-vision bulb that failed appears to have had a manufacturing defect - the plastic hole where the tube exits was chipped. That may have contributed to its early failure. Unlike the GE bulb, it did not emit any smoke when it failed. The ends of the bulb darkened, but it died free of smoke stink. I don't know about anyone else's SO, but mine can smell a lit cigarette in a car a mile ahead of us on the highway so burning bulbs is a really bad thing. Has anyone cut open a CFL before? Any pointers? -- Bobby G. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

It uses a larger share of electricity than lighting so its banning would go a lot further towards saving the earth. Of course, that might create social conflict if folks follow my other suggestion that to avoid the need for cleaning shower walls one should just avoid showers. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

> I think we should just ban air conditioning. There's a better solution. Build a tunnel from Alaska to Florida and ship the cold air down here. No, wait. That won't work. Without doing anything useful about global warming, Alaska will be like Florida by the time we finish the tunnel (or that idiotic fence along the southern border). > It uses a larger share of electricity than lighting

There's a better solution than that as well: Save water. Shower with a friend. One can wash while the other scrubs the stall; then swap. -- Regards, Robert L Bass =============================>

In a state like Idaho, where electricity comes from hydro, the CFL equation falls flat on its face. They add mercury to the environment without providing any "offset" at the stack because there IS no stack. More than that, the article makes it clear that the biggest gains are going to come from regulations limiting what coal plants can expel into the air. It's going to make power more expensive, at least in the short run, but the paybacks will be real and enormous. That much is clear from the record of states that have taken the right steps. Dribs and drabs won't clean the air and neither will the commercial sector because there's no profit in it. That's when governments are supposed to step up and do the right thing. There was an interesting sidebar, too: NASA Chief Not Worried About Climate http://hosted.ap.org/dynamic/stories/N/NASA_CLIMATE_CHANGE?SITE=AP&SECTION=H OME&TEMPLATE=DEFAULT&CTIME=2007-05-31-20-30-15 It makes the point that we're rather arrogant in assuming now that man rules the planet, all climate change must cease. All it would take is another Krakatoa-sized eruption in the world to turn on some serious global air conditioning. The soot from such eruptions typically blocks significant amounts of sunlight for years and years. -- Bobby G. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
