Interesting.

I have heard before about the rr. looking for alternative fuel.  Liquid ng has several problems.  One of the major ones is it can really go BOOM.  They wanted to liquid it in South America where it was plentiful and ship into the west coast ports.  No west coast port would give permission for such an off load.  A ship full of that could cause damage to an area several miles around it if it would explode.  Hmmmm. 

Shoot they can't even get the current pipe line project past the gov. much less additional ones to move these sealed packages.  Plus something is going to have to power those containers.  The greenes  will call it pollution no mater what you do. 

Cheers.
