US Warships Could Soon Run on Detonated Waves

Every one of the modern US Navy’s 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both. But as fuel costs continue to rise, these turbines now burn through nearly $2 billion of fuel annually. That’s why the Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada’s energy consumption by as much as 25 percent (and save $400 million a year) even as the Navy transitions to “all electric” propulsion systems.

This Robotic Mining Car Never Stops Hauling

The demand for minerals is skyrocketing—not just for rare earths like neodymium, europium, and cerium used in the iPhone 5, but phosphorous and coal too. As that demand rises, miners must dig deeper into the ground. But the lower they go, the more dangerous the job becomes—71 miners died in 2010 in the US alone. This automated mineral transportation train, however could boost mining production without jeopardizing lives. More »

These Remotely Operated Boats Will Defend US Harbors—With Surface to Air Missiles

The Piranha USV may be a visually striking vessel and well-suited for costal patrols, but at 54-feet in length, it’s far too bulky to effectively protect harbor interiors and the close quarters between US warships. This 11-foot inflatable from Rafael Industries, however, is small—and deadly—enough to defend the tightest of portsmouths. More »

This Tracker Torpedo Keeps Social Tabs on Sand Tiger Sharks

Sand Tiger sharks have been patrolling coastal waters worldwide for more than 250,000 years. But with only a pair of pups born every few years, this placid apex predator is succumbing to human pressures. Part of the problem is that we still know virtually nothing about their habits—we can’t help them if we don’t understand them. But that’s fast changing thanks to this seawater-sipping, shark-shadowing, scientific submersible. More »

HAL: The Do-Gooder Exo-Suit With the Really Evil Name

While it’s a shame that the Fukushima disaster could well have been prevented, you can only dwell on the past for so long. If Japan is to move on from this disaster, the Fukushima facility must come down. But how does one disassemble such a highly radioactive structure? One research team hopes the solution involves this new generation of radiation-shielding, strength-magnifying exo-suits. More »
