Was on a cruise, and the ship had multiple LM2500s...they scream on land, but on a cruise ship were very very benign (better than the diesels on a later cruise IMO).
Clearly they switched fuel when on the ocean...not noticeable to the other passengers, I was paying attention.
Honestly, I believe it's much ado about nothing.
Although Nukes make perfect sense...in a world where it's more "efficient" (in a Keynsian sense) to make sheetrock in china and then float it over the ocean to another country half a world away.
Real world, thermodynamic efficiency (I've been an efficiency engineer in my past), manufacturing would be distributed across a nation, and rail would move it between hubs. The only things shipped would be items of scarcity.
Oz exports massive amounts of NG...So much so that we are about to start importing it at the same time as we are exporting it...surley some heads could get together and do contractual swaps for the benefit of us all...but that doesn't keep the moneygoround pumping.
