Redshift - Sorry, I must have missed that link - in fact I went back and looked just now, and it only has 27 posts in it, and no linky from you.
So I just did a search for the data on that, and found the EPA report on it.
http://www.epa.gov/oig/reports/2009/...-09-P-0125.pdf Nowhere does it say that only 15 ships account for that much pollution.
Quote:
EPA estimated that in 2001, ocean-going ships emitted:
• more than 54,000 tons of fine particulate matter, which is equivalent to the
pollution from 117 coal-fired power plants,
• approximately 745,000 tons of smog-forming NOx pollution—comparable to the NOx emissions from over 800 million of today’s new cars, and
• about 450,000 tons of SO2, which is more than 40% of the total SO2 from the mobile source sector.1

And further in:

In 2007, Category 3 marine engines (large oceangoing vessel engines)14 emitted more than half of the mobile source SOx inventory for the entire United States (almost 530,000 tons).

NOTICE: thats ALL Cat 3 (large ocean going size) marine engines, not just 15, only emitted half the total for the US.
There are three main categories of emissions, NOx, SO2, and one other, but only the SOx was more than 50%.
Did anyone see the Monster Garage episode where they powered a drag car using about 400 Milwaulkee Battery Packs? I only got to see the last 20 minutes of it - but after the robot guy got the speed control tuned it turned the 1/4 mile right at 100mph - somewhere in the 14's if I remember correctly.
