Discourse for all interested in all things air-quality related
First things first. Keep in mind that from now until the middle of February the National Aeronautics and Space Administration (NASA) is conducting aerial air pollution reconnaissance in the skies over the San Joaquin Valley, a purpose of which is “… to help scientists better understand how to observe ground-level pollution from space,” according to NASA. … Read more
This is not complicated. California’s 27,000-square-mile San Joaquin Valley, which is better than 250 miles long by approximately 80 miles wide, is a hotbed of air pollution activity. That air here is frequently polluted is troubling. It is also unhealthful. Coming from a variety of sources – mobile and stationary alike, it’s both all-enveloping and persistent, … Read more
Number 12 in the Clean Air Technologies Series. I don’t consider myself to be an inventor or designer, but in the late 1980s I came up with what I thought was a feasible idea: make use of piezo-electric devices to generate electricity. The specific application I was going for was in the railroad realm whereby … Read more
In the skies above California’s San Joaquin Valley between roughly Bakersfield in the south and Fresno, located right smack-dab in the Valley’s middle, aerial-air-quality surveillance, via National Aeronautics and Space Administration (NASA) aircraft, is in progress. Incidentally, I see this as a good thing. According to a NASA press release, the aerial (in the air) … Read more
In America, highways – known also as freeways, toll-ways, parkways and turnpikes – rule. Fact is, this country is crisscrossed by no less than four-million-lane-miles of road. It was no accident that America plunked down that many lane-miles in so short a time, either. Good, bad or indifferent, credit for this goes to the Interstate Highway Act, passed during the … Read more
PBS’ America Revealed series presenter Yul Kwon, in 2012 remarking on Thomas Edison in “ELECTRIC NATION,” in no uncertain terms, said: “In 1931, Thomas Edison confided to his friend Henry Ford. ‘We are like tenant farmers, chopping down the fence around our house for fuel, when we should be using nature’s inexhaustible sources of energy: … Read more
Estimates are America has nearly 250 million vehicles, the bulk of which are fossil-fuel-driven. That’s a lot of cars, buses, motorcycles, trucks, etc. To keep not only these vehicles on the go, but the bevy of stationary internal-combustion-engine-powered motorized machines, too, takes fuel – and lots of it. While it’s no surprise the fuel available for … Read more
A quick assessment of all of my prior blogposts reveals 31 out of 64 deal with air quality or air pollution issues as it relates to transportation. That’s nearly half. If you’re wondering why such a high concentration, what I can tell you is the majority of the world’s air pollution is transportation sourced. As it … Read more
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
