Ghostswimmer, английский
A sophisticated biomimetic submarine robot or uav (underwater autonomous vehicle) developed for the u.s. navy in 2008 and expected to be deployed in 2009. based on the tuna fish, its mechanism includes a spine with vertebrae and synthetic muscles that drive fins and a tail, turning waves of body motion into propulsion, just as those components perform the same task for the real fish. the tuna was chosen because its family (scombridae) varies in length from 100 cms (blackfin) to 450 cms (northern bluefin), indicating hydrodynamic design adaptable to a wide range of sizes, and so efficient that it allows tuna to make trans-oceanic migrations at speeds of up to 70 km/h. the system is expected to use less power than conventional propeller-drive, to have approximately three times the endurance, and to be relatively silent and stealthy. the tuna-like size and shape of prototypes will allow them to blend into the underwater background, making them perfect for intelligence- gathering. if these small versions perform as expected, the navy hopes to adapt the concept for full-size submarines.
Ghost ships, английский
There are several types of maritime apparition. some are thought to warn of coming disaster while others recall earlier tragedies. the block island phantom does both. some, such as the cursed corsair, the flying dutchman, and the japanese yureisen, are sinister specters that appear out of nowhere. others were mystery ships like mary celeste, discovered intact with crew mysteriously vanished. and some appear to be explicable phenomena such as the chaleur bay phantom and jenny the glacial ghost. interestingly, some 90 percent of all phantom ship sightings are between the fortieth and fiftieth latitudes.
