Trouble with natural gas... people are almost as terrified of frac'ing, and shale gas as they are of the evil "tar sands". That said, the rest of the world is investing heavily in Canadian natural gas - it's one of the primary motivators behind the current national debate (in Canada) over pipelines out of Alberta.

Can a large cargo ship be run using only liquid natural gas? Can we power generators using just natural gas?

I'm very curious about the limits of natural gas as a power source.
