      Make no mistake about this: the time cost and labor cost of transporting goods across oceans, will absolutely soar as the oil supply peaks and begins to decline, and then as shipping converts to sail power.

      Just as one example, look into international shipping rates over the past ten years, for packages going overseas.  

      One way out of that is with nuclear powered vessels, but the blunt fact is that commercial shipping lines can't be counted on to maintain the safety track record of the US Navy when it comes to reactors at sea.

      Another possibility is the use of rigid airships: huge cargo Zeppelins, kept aloft preferably by helium (which is scarce and expensive) or otherwise by hydrogen (which is hazardous).

      But anything short of antigravity drive (don't laugh: the aerospace industry was all excited about it in the 1950s) will cause the price of that morning cup of coffee to soar.

      "Minus two votes for the Democrat" equals "plus one vote for the Republican." Arithmetic doesn't care about your feelings.

        I think 1/4 of a tall might even give you a cup.  

        As cool as airships are, their future - if any, given the embodied energy of all that aluminum - is limited.  The Hindenburg, longer than three 747s and twice as tall, could carry 75 passengers and 40 crew, and had a useful lift of only 20 tons. That's less than half of just one fully loaded 20' shipping container; the Emma Maersk, the world's largest container ship, can carry as many as 15,000 20' containers.

      •  If we are forced to go back to wind... (0+ / 0-) the principle transoceanic means of transport, the additional transport time becomes "a wash" in due course.

        Transport doubles as essentially "inventory on the move", and depending on the nature of the cargo (perishable or otherwise) the additional travel time will be incorporated into the processing protocols. Or may provide opportunities for domestic alternatives to prove themselves cost-effective.
