Underwater Transport.

1960's Concepts.

Since these ideas of using civilian submarines in the 1960's no progress has at yet been made to bring anything outside the tourism industry to fruition. Australia and Israel are perhaps only two countries in the world to see the value of using submarines to view coral reefs and low level sea plains.

It is either the financial viability, costs and safety that has blocked the serious alternative to surface shipping. It would seem that the Submarine is to remain for some time yet the preserve of the military and Navies of the globe.

The advantages of not having to cope with rough seas and the probability of better speed to deliver goods has it would seem been placed on the sidelines of conventuality. 

But perhaps with the need to cut down of fossil fuels and carbon emissions the day of submersed travel might in this century be not far away?

Submarines.

This is perhaps the least most exploited technology for civil use re-cargo and passenger travel. Yes I recognise that there are various mini submersibles for deep sea research and exploration, but why are their no cargo vessels or commercial liners for under the sea? Is it to dangerous or to expensive, or is there no real interest?
