#Octopus inspires silent propulsion system for boats and subs Along with their writhing tentacles octopi and squid sport another interesting feature-they swim not by swishing a tail
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.
the number of electric cars boats and bikes in operation continues to grow and it's essential for the future sustainability of the planet that these vehicles are able to cope with the increasing demands being put on them.
Because RF Safe-Stop works on electronic systems, it can also be effective on boats. However, it s likely useless against older cars.
a boat or motorbike. One kilogram of plastic produces almost one liter of oil. To convert that amount takes about 1 kwh of electricity,
the oil produced is used for tour buses or boats, Ito says.####Plastic s carbon footprint includes landfilling and incineration,
"Other applications include general anchoring, even in boats, "he added.""We could also use the Roboclam to lay underwater cable,
If an enemy boat or aircraft gets too close to a Navy ship, the laser can deter the threat with an effect known as optical"dazzling."
creating a buoyant force just like the one that floats a boat. That means that the height at which a cell levitates depends on its density.
Depending on how the sailing speed of the boat relates to the speed of the spool
or in meandering, coiling patterns. f the boat is sailing slower than the rate of the cable,
But if the boat is traveling faster, then the cable can get taut and fracture,
#Navy Demonstrates Swarm Of Armed Robot Boats Call them sea drones dronaughts or roboats the Navy demonstrated a swarm of remotely-controlled boats on the James river In virginia this August.
As if animated by the same mind the13 patrol boats all moved in unison their crewless decks painting a picture of
while still keeping boats in the water. Here s what that exercise looked like: Key to the boats is named a program Control Architecture for Robotic Agent Command and Sensing or CARACAS.
According to the ONR CARACAS allows boats to operate autonomously without a sailor physically needing to be at the controls including operating in sync with other unmanned vessels;
choosing their own routes; swarming to interdict enemy vessels; and escorting/protecting naval assets. In the demonstration the Navy boats first escorted a high value unit simulating a ring of robotic bodyguards around a vessel in a narrow part of the sea.
Then with the support of a manned helicopter overhead designating a contact of interest for the boats to intercept they swarmed around their target.
The boats'autonomy is enabled by a sort of hive-sense. The unmanned surface vessels are linked and together they share information from their sensors.
Each boat knows its own surrounding environment and the location of other vessels and it shares this situation awareness with the other ships in the swarm.
On the phone with media Read Admiral Matthew L. Klunder and ONR program manager Robert Brizzolara confirmed that
while the robot ships had the ability to move on their own there is always a human in the loop before the robot boats fire their weapons.
Should the signal with the controller be lost the boats will stop themselves. There s also another kill switch that the controller can press to make the robot boats stop dead in the water.
The boats are all patrol craft typically crewed by four to five sailors. Replacing the crew with robotic controls means the Navy needs 40 to 50 fewer people for a 13-ship exercise.
That means more lives out of harms way as well as saved costs on personnel. The boats are existing Navy craft
and ONR said they were armed with a variety of weapons--from. 50 caliber machine guns to high-powered microwave weapons.
since unmanned swarms of up to 20 boats can be controlled by one sailor at a time. And they can use fewer people;
but it's possible that an unmanned robot boat could intercept a vessel full of suicide bombers.

A boat made of such lightweight composites will not sink despite damage to its structure. The new material also promises to improve automotive fuel economy

and unless boats and fishing gear are cleaned thoroughly they can carry spiny water fleas and their resting eggs between lakes infecting one after another.
If you want to use your boat sooner clean all surfaces with hot (over 104 degrees F.)water a high-pressure hose or a disinfectant like a household bleach solution.

Unfortunately that doesn't stop the odd Typhoid Mary. In some places along Highway 41 in Upper Michigan's Keweenaw Peninsula every lake we tested with a boat ramp had Bythotrephes.
