PS The EPA legislates the speed limit in the city of Houston and is why our highways do not permit 65MPH in the city anymore.
Unelected legislators. Wonderful.
And our pollution standards will not be met by attacking the car.
But there is an added push for more fail rail.
There they go again, moving the goal posts just as the line is approached.
Zero tolerance. Who ever thought they would just keep hunting up more and more sensitive recording instruments?
What is ozone, anyway? It is a tri-atomic form of oxygen, and even more reactive in the presence of substances which are prone to oxidation. Thus it disappears rather quickly down here close to the surface. O3 is in fact slightly HEAVIER than CO2, and is readily absorbed by surface water or raindrops, where it enacts its mischief below the water’s surface.
Electrically powered surface rail transport systems generate a considerable amount of ozone from the sparks that jump between the separation of one transfer surface to another, as seen within a brush-type electric motor or generator unit. Most of this, however, is wafted away before it is adequately measured, while that generated by operation of internal combustion engines tends to collect below the freeway overpasses.
