Junk science from the fringe, or, how 4,000 gallons of gas burned next to my house today

My city is laid out in 1 mile grids  The one mile square I live in has 4 lanes on all 4 sides of it.  The 3 year old traffic count I found on line gives each side of the square a value, combined its almost 75,000 vehicles, which in this case would also be about 75,000 miles driven.
The national fleet (the whole mix of cars and light trucks) now gets at best 20 mpg.  Now I'll spare the math here but it works out to 3,750 gallons burned every day on the perimeter of my square just for the drive.  At each of the corners is a traffic light, about 1/3 of the cars get caught at one end or another of this mile and set for about 3 minutes, so thats 75,000 minutes burning 1/4 gallon per hour at idle, for another 312.5 gallons just to go nowhere.

That's 4,063.5 gallons up in smoke every day, and close enough to be a concern.  (todays price $3 gal).  Tomorrow I will find out how much CO2 that was.

  1. Math doesn't lie. I have wondered for a long how much the military uses and awhile back saw something on that very thing but didn't save it. Some ungodly number that is off the map.

    I can see I can not back away entirely from the internets while I'm gone BTW.
