Many of the bleeding edge thinkers on oil decline point to nuclear energy as being a valid substitute to diesel in freight shipping.
It seems that the freight shipping industry itself has finally sat up and taken notice. About time too I say to myself.
Anyways... One of the largest shipping and freight operators in the world, greek shipping operator Enterprise Shippind And Trading S.A. has gotten together with Hyperion Power and discussed the concept of powering the shipping fleet with nukes.
This has already been tried successfully by the Germans between 1970 to 1979 on a nuclear powered freighter called Otto Hahn.
So the crap we buy from Wal-mart will still be arriving from China much to the chagrin of our "green" friends, likewise the 4000 mile salads even post peak.
