System upgrade - The world of tomorrow [Marine transport]
Marine transport is a very important sector of the transportation field, the most popular and efficient marine transport means is ship .
Ship transport is watercraft carrying people (passengers) or goods (cargo).
Freight transport has been achieved widely by sea throughout recorded history. Although the importance of sea travel for passengers has decreased due to aviation, it is effective for short trips and pleasure cruises. Transport by water is cheaper than transport by air, despite fluctuating exchange rates and CAF charges to account for such.
Ships won't be improved some much because major technical efficiency limitations are reached, the only things that will be majorly improved are engines, that have an actual very bad efficiency.
As non-renewable energy sources won't be avaible in the future or far too expensive, engine will probably be based on electrical or renewable fuel technologies.
Ship
Considering the electrical motor effiency of up to 95% source, electrical motors are the best suited alternative to current ship diesel engines that have an maximum efficiency of 52% source and low cost production price.
As lithium-ion battery are too costly and weak for this purpose, small ship will probably use solid-state battery chemistry with glass electrolyte and medium to big ships will probably use fuel cell because of their huge energy storage capacity.
