One ship in Panama Canal paid $2.4 million to skip the line

3. 24,000 containers fit on a cargo ship

So that doesn't add too much per transit. And oil can be 200,000 to 500,000 barrels, which is ten or more millions of gallons. So the above estimate of +$0.10 per gallon might not be far off. Whew what a world. I still remember arguing with a physics professor in a "Science and Social Science of Energy" class about whether burning fuel would add up, when the CO2 levels were already well above 300ppm by 1988. He was conservative and very pro nuclear. I'm scared of the waste that will surely outlast current containment vessels, and to even try to store in materials that will last long enough extra cost is needed that no one wants to pay.
