[The
Trans-Atlantic Tunel : USA,UK]
|
Under ocean tunnels, not Overseas routes; a great concept!! Have you ever imagined that you are driving from New York to London? And what if through a Trans-Atlantic tunnel through the ocean? Surprised of such a tunnel? But short time left to make it a reality. Engineers are working on it. One should rather watch the Extreme engineering video on that than simply talking on what they might have done what they have planned.
The
tunnel is to be made of huge discrete hollow concrete ducts joined under the
ocean to make up a path/tunnel under ocean. Several aspects like depth of
ocean, safety, water current, hydrostatic force, water seepage, uplift, fixity
under ocean, construction under water, emergency exit, bulky blocks,
communication, feasibility, economy etc are discussed in the clip. The documentary
discusses the constructional and operational aspects that would come across. And
the main [points out of these were: It is challenging to keep floating-tunnel in
position, not floating away. But with the use of cables it can be solved. Tunnel
ducts will be suspended on cables like in bridges, but suspended upwards and
under water current and buoyancy instead of gravity. And the first question
from a common man would be that, would it be worth the effort? The answer is expected
to be YES and if made clearer, SPEED. London to New York in 1hr. But for speed
the tunnel should be made vacuum. But it should be made controllable. Passengers
will feel discomfort. Human body can’t adjust with the acceleration in vacuum.
There
arises the second question what if Fire comes? Or what if a nuclear submarine
lost midway under the ocean hits the tunnel? All these are answered
optimistically in the documentary. Astonishing computer graphics on what they
are planning gives a clear idea on the project. This ambitious plan will be the
world’s largest, most complex, most expensive, massive construction if done.
As
Wikipedia says, A transatlantic
tunnel is a hypothetical tunnel that would span the Atlantic Ocean between North America and Europe,
and would carry mass transit of some type—trains are envisioned in most proposals.
Using advanced technologies, speeds of 500 to 8,000 kilometers per hour (310 to
5,000 mph) are envisaged.Plans for such a
tunnel have not progressed beyond the conceptual stage, and no one is actively pursuing
such a project. Most conceptions of the tunnel envision it between the United States and the United Kingdom, or, more specifically,
between New York City and London.The main barriers to constructing such a tunnel are cost - from $175 billion
to $12 trillion - and the limits of current materials science. Existing major
tunnels, such as the Channel
Tunnel and Seikan Tunnel, despite using less
expensive technology than any yet proposed for the transatlantic tunnel,
struggle financially. A transatlantic tunnel
would be 88 times longer than the Gotthard
Base Tunnel and 36 times longer
than the Delaware Aqueduct. In
2003, the Discovery Channel's show Extreme Engineering aired a program entitled
"Transatlantic Tunnel", which discussed the proposed tunnel concept
in detail.
