Martin and Wayne, 
The solution is to abandon this foolishness because it makes no more sense than a State funded and managed LNG export project given our current and projected fiscal situation (not to mention the demonstrated managerial  prowess of our state government) .  As to cost of transport; according to the Federal Department of Transportation, other than pipeline, water transport has the lowest cost per ton per mile when compared to air, truck, and rail. For example, in 2007 (the year when all four provided comparative data), to move a ton of freight one mile cost 89.71 cents by Air,  16.54 cents by Truck, 2.99 cents by Rail and 1.61 cents by barge.
