Descending to New Ocean Depths
We know little about the ocean yet. The dream of exploring under the
waves is almost as old as seagoing. Legend says that Alexander the Great
submerged himself in a round glass container, and Leonardo da Vinci designed a
submersible vehicle in his notebooks centuries before Jules Verne wrote «Twenty
Thousand Leagues Under the Sea». If their dreams had been realized and such a
craft had been constructed, mankind would have known about the secrets of Ocean
much earlier. However, already during the Swiss National Fair in 1964 a
submersible vehicle took thousands of people deep into Lake Geneva.
Not long ago, the crafts that penetrated the ocean depths were almost as
primitive as the marine life they watched around them. However, non-military
deep sea ships, so-called submersibles, were progressing rapidly. Russian,
French, Japanese and American scientists are developing crafts that can
submerge deeper, stay longer and find out more than earlier apparatuses.
Soon, one of the most advanced crafts, a one passenger submerging ship,
will be tested. It may be able to take explorers and technicians deeper than
ever before (up to 3,300 feet) and perform difficult underwater tasks with
extreme precision. |
The Return of the Dirigibles
When it comes to technology, people are not inclined
to return to the past. Yet, some exceptions do exist. Such is the attitude at
present towards dirigibles. Having abandoned the skies more than 40 years ago,
they have suddenly begun to reappear. Designers have once again sat down to
design this kind of transportation. Their use can still be limited, but there
is no doubt that dirigibles are coming back.
Why is dirigible attractive? What do you
do with it? As its cruising speed is about 60 miles per hour, it is too slow to
be used as a passenger carrier. But it is cheaper to operate than a helicopter,
comfortable and capable of flying for several days. The craft's large size and
staying power (dirigibles have remained in skies for as long as a week) make it
ideally suited for exploration.
Their use in countries that have large
territories and are rich in forests and are planning to explore and exploit new
regions is most promising. They may be used to make a geological survey and to
make maps, to look for off-shore oil and minerals, to take tourists to
roadless, but beautiful places, to deliver heavy loads to remote regions and
bring the products back. They have a potential use as a flying platform. In
general, their possibilities are endless. They do not need expensive runways
required by cargo planes. |
