3D printing technology makes it possible to construct real objects from virtual 3-D objects.
Robotics will drive efficiency and also prevent workers from doing dangerous tasks such as welding.
This will mitigate the problem of ballast water disposal which causes discharge of non-native species.
LNG is popular as an alternate fuel for ships because of its environmental friendliness.
Many technologies have come which support big ships to reduce fuel consumption by utilizing solar panels or rigid sails.
A vessel built from this lighter material would require less fuel, hence increasing energy efficiency.
The system would use electric transmission instead of mechanical transmission, eliminating the need for clutches.
