I was stopped at a railroad crossing yesterday when the noon freight went by. I've seen this train dozens of times. Never saw those coal cars before, though. There must have been close to three dozen filled to the brim clickety clacking down the track here in eastern MA.
I've got another article I'll post shortly on the economic viability of America's coal.
With gasefication and liquefaction to replace ALL of our imported oil needs, we will increase our use of coal from 1.06 billion to nearly 2 billion tons a year.
That gives us over 800 years of supply....NOT CONSIDERING advances in technology.
