For example drug smugglers recently have deployed makeshift submarines to clandestinely ferry narcotics long distances underwater. An improved more robust underwater sensor network could help spot these vessels.
Scientists from Germany's Fraunhofer Institute for Manufacturing Engineering and Automation have copied now this system in a propulsion system that could ultimately find use in boats recreational watercraft or submarines.
with the exception of some aircraft carriers and 72 submarines that rely on nuclear propulsion. Moving away from that reliance would free the military from fuel shortages
#$1. 7 million personal submarine lets you'fly'underwater Adventurers with deep pockets can now explore the hidden depths of the ocean,
thanks to a futuristic submarine that lets users"fly"underwater. The Deepflight Super Falcon, developed by California-based Hawkes Ocean Technologies,
"The submarine is 21 feet (6. 4 meters) long, and has a wingspan that stretches nearly 9 feet (2. 7 m). The submersible can carry two
submarines are constructed with an inner shell and an outer shell. To dive, submarines fill the space between the two shells with water,
changing the ship's density and creating so-called negative buoyancy when the gravitational tug on the sub is greater than the force of buoyancy.
When submarines remain on the water's surface the area between the two shells is filled with air,
Hydrogen fuel cells can power vehicles ranging from cars to submarines and rockets. They can also heat buildings
Many applications such as submarines sonar systems instead use two-dimensional arrays and in that case the savings compound:
In the 1966 movie Fantastic Voyage a submarine complete with crew is shrunk in size so that it can navigate through the human body enabling the crew to perform surgery in the brain.
Nevertheless tiny submarines that could navigate through the body could be of great benefit: they could deliver drugs precisely to a target location a point on the retina for instance.
Indeed a scallop-shaped miniature submarine could also be driven by an actuator that responds for example to temperature changes.
The tiny submarine could also be used in media other than synovial fluid. Other liquids in which such nanovehicles could deliver drugs for example include the vitreous humor of the eye mucous membranes and even blood.
Like tiny submarines these versatile nanocarriers can navigate in the watery environment surrounding cells and transport their guest molecules through the membrane of living cells to sequentially deliver their cargo.
When you launch a missile from a submarine its launch characteristics are going to be perturbed by the gravity field Sandwell explains.
American nuclear submarines, hiding out at sea, used geo-locating satellites to calculate target trajectories, so that they could reliably hit the same points on earth from anywhere.
The invention could pave the way for the development of'flying submarines'-vehicles that can seamlessly travel through air and water
efficiently remove carbon from the ambient air of a submarine as readily as from the polluted emissions of a coal fired power plant.
or, in the case of a submarine, expelled into the sea.""Carbon dioxide is 15 percent of the gas coming off a power plant,
can be tuned to remove carbon dioxide from the room-temperature air of a submarine, for example, or the 100-Degree fahrenheit) flue gases from a power plant."
"From flue gas to submarines Power plants that capture CO2 today use an old technology whereby flue gases are bubbled through organic amines in water, where the carbon dioxide binds to amines.
"We're also hoping to develop something that might be tested in a submarine, "Long said.
but the design is written broadly enough that it can potentially protect everything from ships to submarines, offshore platforms, ground vehicles, buildings,
Some engineers for instance have used the idea of grid cells as inspiration for new algorithms to control robots or autonomous submarines.
India plans to expand its nuclear submarine fleet, and Pakistan has started reportedly operating a third plutonium reactor,
they might even be able to pick up the movement of submarines below the water surface.
In yet another experiment, the U s. Naval Research Laboratory showed that it was possible to release a drone from a submerged submarine with the robotic drone shot out of a Tomahawk missile tube.
