Quite
an interesting invention.
He built it himself and
it is the smallest submarine in Russia, officially registered
as a boat by Russian boat registry and has got it´s
own personal name and number.
A submarine is a watercraft that can operate independently
underwater, as distinct from a submersible that has only
limited underwater capability. The term submarine most
commonly refers to large manned autonomous vessels, however
historically or more casually, submarine can also refer
to medium sized or smaller vessels, (midget submarines,
wet subs), Remotely Operated Vehicles or robots. The word
submarine was originally an adjective meaning "under
the sea", and so consequently other uses such as
'submarine engineering' or 'submarine cable' may not actually
refer to submarines at all. Submarine was shortened from
the term 'submarine boat'.
This Russian man from St. Petersburg got his personal
submarine. He built it himself and it is the smallest
submarine in Russia, officially registered as a boat by
Russian boat registry and has got it´s own personal
name and number.
He can make an underwater trip from St. Petersburg to
Helsinki, Finland and back without stops, and he can go
as fast as four knots.
The interesting thing that he is based in St. Petersburg
which is in Northern part of Russia so the water in the
sea is cold all year round... |
