Discourse for all interested in all things air-quality related
Number 10 in the Clean Air Technologies Series. When it comes to powering a locomotive, electricity wins hands down, or does it? Before going any farther, a brief review of 20th century U.S. transportation history is in order. I was born in the age of the diesel loco. Steam as locomotive propulsion power, although reaching a zenith right around … Read more
A segment of the Jan. 13, 2013 installment of the CBS 60 Minutes television program covered robotics. Given that I have now had plenty of time to digest what I have watched, my take is, robots, with their ranks apparently increasing, I can only imagine the effect on the electric grid supply and the environment. The presumption, of … Read more
I have put off discussing indoor air quality long enough. That changes today. California right now is feeling the effects of a cold front that has swept down out of the Gulf of Alaska driving nighttime temperatures into the low-to-mid-twenties over much of the San Joaquin Valley floor. Many, it seems, are right now relying on a … Read more
In America a half-century ago, transportation ate up approximately 10 percent of household income. Those days and times are gone for good, but, then again … At any rate, according to renowned architect, a founding member of Congress for the New Urbanism and book author Peter Calthorpe in “The New Transit Town: Best Practices in Transit-Oriented … Read more
Number eight in the Clean Air Technologies Series. Think how many fugitive vapors or emissions there are in the world. What if they could all be captured and put to good use? In “Device converts manure gases into clean and useful energy,” discussed was how methane, a biogas emitted naturally from manure and, how with the … Read more
In “Trains prove their worth in helping improve air,” I offered, “In the final analysis if the growth in passenger train ridership is to continue, then additional service will be necessary. ….Electrified California high-speed rail service, on the other hand, expected to break ground later this year, when built and operational, will provide a viable alternative to meet … Read more
Number six in the Clean Air Technologies Series. Every winter in America, it seems someone loses power to the home. Now add to this that about half this nation’s electricity production alone is via the burning of coal. In putting two-and-two together doesn’t it make sense that when such extreme conditions become present, losing power … Read more
There are all kinds of ways to make air cleaner – everything from the simple to the substantial and from the subliminal to the sensational. From an earlier post – “Air pollution: The enormity of it all,” I listed various pollution sources. Repeating those here, these are: Agricultural Commercial (Business) Construction (and Demolition) Energy Production … Read more
A little more than a month into this air quality discussion and noticeably lacking has been power generation. In this regard, change starts today. And what better place is there to begin than in my own home? I can think of none. It is helpful to understand the geography and meteorology of California’s San Joaquin Valley; the place I … Read more
Number four in the Clean Air Technologies Series. There is something about a train. In fact, it was none other than Poetry Pulitzer Prize winner Edna St. Vincent Millay who, in true poetic form, in “Travel,” wrote: “Yet, there isn’t a train I wouldn’t take, No matter where it’s going.” Amen! One would not be incorrect … Read more
