Sea Eagle uses a total of 5,000 hp from solar hybrid power sources

The US Coast Guard Sea Eagle uses a total of 5,000hp from Solar Hybrid power sources that include cleaner MTU tier 4i Diesels. With less than half the fuel consumption of the Sentinel Class FRC's.

New harvesting approach boosts energy output from bacteria

A team of scientists from University of Colorado Denver has developed a novel energy system that increases the amount of energy harvested from microbial fuel cells (MFCs) by more than 70 times.

Self powered robot jellyfish

Researchers at The University of Texas at Dallas and Virginia Tech have created an undersea vehicle inspired by the common jellyfish that runs on renewable energy and could be used in ocean rescue and surveillance missions.

Tandem polymer solar cells that sets the record for energy-conversion

In the effort to convert sunlight into electricity, photovoltaic solar cells that use conductive organic polymers for light absorption and conversion have shown great potential.

Graphene rips follow rules

Research from Rice University and the University of California at Berkeley may give science and industry a new way to manipulate graphene, the wonder material expected to play a role in advanced electronic, mechanical and thermal applications.

Graphene lights up with new possibilities

UNO earns $900k award from ONR to build robotic eel

The University of New Orleans is the recipient of a 3-year $937,000 award from the Office of Naval Research to design and build a new type of robotic "eel" that is capable of operating in shallow water environments where Navy personnel could be at risk.

Autonomous Underwater Vehicles get cleverer

Kongsberg is the world's largest manufacturer of Autonomous Underwater Vehicles. These are almost always pure electric vehicles but some can have fuel cell range extenders, making them hybrids. A leading researcher developing and deploying AUVs including ones that can surface to garner wave and solar power to charge the batteries before diving on their way is Monterey Bay Aquarium Research Institute.

This article shares some of the research carried out for the new IDTechEx report, "Electric Vehicles, Military, Security, Police 2011-2021".

Development of ocean power harvesters

Battelle and Levant Power Corporation have announced that the two companies plan to develop and commercialize wave energy harvesting technology for ocean systems.

Fuel-cells power German super-stealth submarine

In 1994 German naval manufacturer Howaldtswerke-Deutsche Werft began developing technology for a non-nuclear, super-stealth, hybrid submarine. The first models were released in 2003 with the updated versions recently revealed.

Diesel-electric submarines to be tracked by unmanned marine vessels

Diesel-electric submarines are difficult to track as they are virtually silent and can stay submerged for extended periods of time. As the Defence Advanced Research Projects Agency (DARPA) attempts to counter this imposing threat through the Anti-Submarine Warfare Continuous Trail Unmanned Vessel (ACTUV) project, multiple companies have received design contracts for the proposed vessel as the initial phases of the project get underway.
