You can bet pipelines are on the drawing board as I type. Just like Pennsylvania in the beginning. First there were wagons moving oil to the refineries, next came trains, then pipelines. You just can’t do it cheaper.
Or safer. No train to derail, no truck to wreck, no ship to run aground. If it works the first time, it continues to work as long as the pipe stays sound and the welds don't crack--and that can be inspected oftenenough that problems can be caught before they happen or get too serious.
Then all you need to do is to keep idiots from digging holes in it.
