Submarines.

Still less Utilised.

The world of the submariner seems to remain in the hands of the military in relation to the commercial procurement of its use in shipping and travel?

Submarines can be developed to move cargo and is used on a limited scale for underwater tourism, but is it not time to harness this extra form of travel over that of air pollution and the expanse of the claimed carbon foot print.

Many robotic small subs are being harnessed daily by the scientific community to explore the depths, to search for sunken treasure and to do seabed pollution investigation.

Cranes.

Free Standing and Telescopic.

We today live in a world where we think cranes are something new? But we have had a pulley crane of some description since humans needed to lift heavy weights. Those fantastic monuments of the past such as the Pyramids in Egypt, the great wall of China and the many neolithic monuments needed cranes.

Today cranes come in all sizes and formats. They are the centre of the construction of high rise buildings and also entry work to underground tunnels. Cranes in the telescopic type are used to lift heavy weight objects, from piping units to wind turbine segments to skips of materials needed at certain heights or depths. 

Some cranes work on a segmented construction basis, while others are deployed from an eight to twelve wheel truck unit.
