UAVs Will Study Californian Smog

Roland Piquepaille writes "The California Energy Commission is funding a research effort named CAPPS, short for California AUAV Air Pollution Profiling Study. CAPPS will use autonomous unmanned aerial vehicles (AUAVs) to gather meteorological data as the aircraft fly through clouds over Southern California. The goal is to study smog and its consequences as well as better understand the sources of air pollution. The first flights started in April 2008 and data collection will continue until January 2009. But read more for additional references and photos of these autonomous unmanned aircraft."

      Two-stroke engines, on the other hand, are still basically unregulated, and in many cities exceed passenger-vehicle tailpipe emissions as a pollution source. You can easily produce more emissions in 1 hour of mowing your yard than in 10 hours of driving!

      Not even the easy, cheap changes that would give a 99% reduction to two-stroke emissions are being considered, while people argue for quite expensive changes to cars that would suqeeze out one more 1% reduction. I guess people are more concerned about ideological fashion ("we all know cars are evil, right?") than actually reducing smog.

    b) lower than the rest of the state in income and education, and
    c) higher than the rest of the state in poverty.
    If anything, it seems to indicate a correlation between poverty and illness. Hardly a surprise.

    - Schwartz's underlying asthma data comes from a report done on children on Medicaid and asthma-related hospitalizations. The original report made no mention of ozone or pollution. The original report also gives the following caveats, which Schwartz made no mention of :

    "Neither source will produce a reliable indication of the total prevalence of asthma among children."

    "Other children on Medicaid with asthma may not have been diagnosed, or may not have had services paid for by Medicaid during the year."

    "The hospital discharge data counts only those cases where the complications of asthma were serious enough to warrant one of more overnight hospital stays."

      Those certainly are a lot of links to agencies with a vested interest in maintaining their funding by hyping the air pollution/disease connection.

      You sound like a lawyer, BTW. What does asthma caused by pets have to do with air pollution? Are there fewer pets on high pollution days? I'm not sure why you'd want to muddy the waters with irrelevancies.

      My main point was that the air is cleaner. It's so clean that it's no longer a problem in most places in the US. There are anti-freedom agencies and activist groups and trial lawyers who will try to sell a false message of horrible pollution for their own personal financial or political benefit.

      Folks ought to understand that they aren't getting the true story (and certainly not the whole story) from these groups and the media who publish or broadcast on their behalf.

      I could research it some more and post some more links, but I'm not a paid activist or government worker. I don't work for a trial lawyer. I have productive work to do and can't spend all day posting propaganda on forums to maintain popular illusions.

      You sound like a lawyer, BTW. Hmm. I'm not sure whether I should feel insulted. I think I'll take it as a compliment, although I generally have a dim view of most lawyers. ;)
      FWIW, IANAL. I work with computers.

      What does asthma caused by pets have to do with air pollution? Are there fewer pets on high pollution days? Asthma has different triggers. The report compares urban and rural environments, but does not explore the differences between them. The report assumes that all asthma cases reported relate directly and only to ozone. Attributing all these cases to ozone is erroneous.

      For example, since urban locations have more restrictions on pets, and since fewer plants grow in cities, it is reasonable to propose that in rural environments there will be a higher percentage of asthma cases related to pet dander and/or pollen than is found in more urban areas.

      My main point was that the air is cleaner. It's so clean that it's no longer a problem in most places in the US. As a country, we have made a lot of progress vs. 50 years ago. I may not be in 100% agreement with your statement, but I can agree to disagree. Neither of us has the time to quibble endlessly.

      There are anti-freedom agencies and activist groups and trial lawyers who will try to sell a false message of horrible pollution for their own personal financial or political benefit. There are a lot of very powerful interests acting against freedom and the greater good in a number of areas. I try to be suspicious of all of them. Question everything. Get to the underlying data. Any position worth your time and reputation is worth scrutinizing thoroughly.

      Folks ought to understand that they aren't getting the true story (and certainly not the whole story) from these groups and the media who publish or broadcast on their behalf. That was my point about the source you cited.

      I could research it some more and post some more links, but I'm not a paid activist or government worker. I don't work for a trial lawyer. Same here.

      I have productive work to do and can't spend all day posting propaganda on forums to maintain popular illusions. Sigh ...

  27. Do they have IFR clearance ? by Anonymous Coward · · Score: 0

    Light aircraft are either VFR or IFR, either way the pilot is responsible to see and avoid other aircraft. UAVs can't do this due to the lack of a pilot, and being much smaller than other aircraft pose a problem to pilots, even if they manage to see one of these, the small size will lead them to think it is much further away than it really is . .

    all it will take is one crash caused by these UAVs to bring on the lawsuits and seriously curtail their use . .
