Is US air quality ever as bad as in Shanghai? (photos)
Yet another evening of bad Los Angeles air quality We won’t bore our readers by pointing out that last night [January 29, 2014] was yet another “Unhealthy for Sensitive Groups” bad air quality day in Los Angeles. (Sensitive Groups includes those athletically inclined.) You can read about the trials and tribulations of our air purifiers from previous days this week and this month. “Lower your standards!” We had a comment exchange on a social media site with someone in Shanghai regarding China’s consideration of spraying water from skyscrapers. China hopes this can bring PM2.5 down to 35 micrograms per cubic meter. We point out this is at the US 24-hour average but still way above the US annual average exposure limit (but below where it has sometimes been in Los Angeles recently). We previously discussed this new technology, and whether it should be applied in the U.S. “Lower (weaken) your standards!”… Read the restCreative Solutions to Air Quality
A positive blog One of our vendors (not one of our readers, apparently) complained recently that air quality and air pollution were less than upbeat topics. That’s the traditional ostrich mind set. “Oh air quality, nothing can be done.” We beg to differ. We’ve done many blog articles about how you can use our free app and simple technologies to control your indoor air quality and fight air pollution. But the news has filled recently with stories about how new technologies finding solutions to air pollution. For example, China is considering experimenting with new technologies to spray water from skyscrapers to bring PM 2.5 air pollution levels down to a somewhat safer 35 micograms per m3. (PM 2.5 levels were recently above that level here in Los Angeles on multiple days so maybe we should be spraying water from our downtown skyscrappers out here as well if it would help. Los Angeles is a large geographic area, however, and one wonders how effective spraying in downtown would be.)… Read the restDr. Beak From Rome and the Black Plague, or why having a surgical mask might be handy
This 1656 woodcut (see photo) depicts the plague doctor “Dr. Beak from Rome” (“Doktor Schnabel von Rom”). His bird mask was stuffed with straw, which served as a crude air filter. Medieval artists alternated lampooned him (as here) and later celebrated him as scientific and practical methods of plague control slowly proved themselves over the more superstitious practices of that era. When we got into this we were thinking about how smart homes (and smarter air purification) could reduce dust buildup in our more dusty urban areas (like urban California, Europe, and Asia). While it was obvious there was a lot of dust buildup on furniture, we didn’t realize just how badly air quality fluctuated from day-to-day here. Bird Flu or just poor air quality Earlier this week one of our staff members saw someone walking the streets of Los Angeles with a surgical mask on. He appeared to be from a part of Asia that had experience with bird flu, and wearing surgical masks on the street is more culturally accept there than here.… Read the restWhy did the toaster salute the CES-announced Internet-of-Things smart range hood? Because it was General Electric.
Smart, Internet-connected kitchen appliances make it easy to prepare Internet spam? We’ve already mentioned that the Internet Of Things was big at the Consumer Electronics Show this year, and have already covered Internet-connected vacuum cleaners with airborne dust sensors. Now, you might not have heard about the smart range hood. (It was, of course, right next to an Internet-connected smart refrigerator, the product labels and exhibit material still in Chinese (see photo gallery), so fresh off the boat is this smart refrigerator technology. Actually, there are several companies with an Internet-connected refrigerator. They are sometimes the butt of jokes. It is technology of the future. It was already the technology of the future at last year’s CES. And probably the year before. A little slow getting off the ground. In more recent news one of these Internet-connected smart refrigerators was recently implicated in spam sending attacks after being hacked. So if there’s spam in your Samsung smart refrigerator, it’s not clear if you mean email spam or Hormel Spam(TM).… Read the restRecent Comments
