  Photo sensor smoke detectors

  Umbra seems to be saying that smoke detectors that use a small light source and a photosensor to detect when smoke comes between the source and the sensor are not good enough.

  That sure goes against what I have heard. They work just fine, but are generally more expensive. The reason americium-241 detectors are so prevalent is that they are cheap.

  So, you decide: Are you willing to pay a bit more for a quality detector that does not contain nuclear waste?On Umbra on smoke detectors posted 9 months, 2 weeks ago 3 Responses

  opinions are like...

  Well, this reminds me of a saying, slightly modified to protect the overly-sensitive among us.

  Opinions are like rump-roasts -- everybody's got one.

  My opinion is that starting to eat flesh is a slippery slope. OK, so you pick and choose to make sure that you are doing nothing environmentally irresponsible, then all of a sudden you find yourself at a friend's or a restaurant, and you go for a piece of flesh that most likely has not been chosen with the same care you would personally exercise.

  Then there's the concept that no matter where you get your meat, it puts pressure on the entire industry to produce more. That means that even by eating grass-fed local beef (or wild salmon), you might be helping out the corn-feed-lot beef (or farmed salmon) industry.

  I find it much easier to "just say no" to animal flesh. Then I do not have to worry about it (other than occasional cravings for Hamachi & Maguro sushi -- good thing for me that there're some great veggie rolls out there).On Umbra on vegetarian remorse posted 2 years, 1 month ago 38 Responses

  PV energy costs

  As for how much energy it takes to make PV modules, depending upon the technology and the geographical location, they will reach energy payback in 2-8 years. With long lives (35 yr. old modules are still making energy)reflected by their 20-25 yr. warranties, PV modules will make lots of carbon-free energy over their lifetimes.
