Dow to Test Algae Ethanol
Startup Algenol partners with Dow Chemical on a demonstration ethanol plant.
Florida startup Algenol Biofuels says that it can efficiently produce commercial quantities of ethanol directly from algae without the need for fresh water or agricultural lands--a novel approach that has captured the interest and backing of Dow Chemical, the chemical giant based in Midland, MI.

How to Make UAVs Fully Autonomous
A smarter vision system could help robotic aircraft detect airborne obstacles.
To become truly autonomous, UAVs will need to get far better at sensing obstacles and reacting in time to avoid a collision. This will be especially important if they are ever to operate in commercial space.

Raytheon Awarded $30 M for Space Fence System Design and Prototyping
Raytheon Company was awarded one of three $30 million contracts for Phase A system design and prototype of the Space Fence system. Space Fence will provide the U.S. Air Force enhanced space surveillance capability to detect and report space objects.
"Space Fence is the future of space situational awareness," said Pete Franklin, vice president for Raytheon Integrated Defense Systems' National & Theater Security Programs. "This sensor will have the capability to detect and track very small objects in low Earth orbit."

New Material Could Cool Electronics 100 Times More Efficiently
Georgia Tech researchers are working on a new novel material for cooling high-powered military radar gear up to 100 times better than current conductive heat-dissipation technology.
Developed in conjunction with Raytheon and DARPA, the material is a composite of copper and diamond, two of the most effective heat-conducting materials. The composite would serve as part of a sandwich of cooling materials called a Thermal Ground Plane, which, combined with a liquid cooling setup, would surround the transmit/receive module in a radar system.

CMOS digital camera reaches 1.4 million frames per second
Vision Research has unveiled the Phantom v710, the latest addition to the company's v-Series of advanced digital high-speed cameras. The Phantom v710 offers an unrivaled throughput of more than 7 gigapixels/s, which allows the camera to record at 7,530 frames/s at its maximum resolution of 1280 x 800.Wealthy arm their yachts with military-level security
The world's richest people are spending millions arming their super-yachts with military-style technology and trained personnel to fight off potential attackers.
The threat of pirates and growing fears that yachts may be their next target have led many owners to equip their vessels with the latest James Bond-like technology.
Hidden chambers, escape pods, tracking devices and ex-marines employed as security guards have all risen in popularity.

US Military Robot Insect Technology in Progress
Military scientists are currently working on a new type of robot technology - insect cyborgs, affectionately known as 'cybugs'! The vision is to adapt actual insects to become surveillance platforms, equipped with cameras and able to access combat areas impenetrable to humans. Generally speaking, the main difficulty experienced so far in the creation of hugely scaled-down variants of UAVs (Unmanned Aerial Vehicles) like the Reaper and Predator drones currently tasked with surveillance missions over conflict zones like Afghanistan has been that of developing a power mechanism for them that combines low weight with high performance.

Iron Dome tested successfully
An Israeli interceptor system developed to shoot down the short-range rockets favored by Palestinian and Lebanese guerrillas passed its first live trial on Wednesday, a defense official said.
Iron Dome's success could improve the prospects of Israel eventually ceding West Bank land to the Palestinians, as Israeli officials have said that any withdrawals should be conditional on the deployment of a reliable defense against rocket attacks.

NASA suits get makeover for moon missions
The new spacesuits being designed for NASA's return to the moon by 2020 as part of the Constellation program are set to be much more sophisticated. As second-generation moon suits, they will be sturdier, easier to move around in, and should be able to recycle resources such as oxygen and water.

US considers expanding army: Pentagon
Defense Secretary Robert Gates is weighing a possible temporary expansion of the US army to ease the strain from wars in Afghanistan and Iraq, his press secretary said on Wednesday.
Gates was discussing the idea, backed by Senator Joseph Lieberman, with senior officers to add 30,000 troops to the active-duty army, press secretary Geoff Morrell told reporters.

Martin JetPack
Capable of 30 minutes of flight at around 60 miles per hour, the Martin Jetpack can apparently go as high as 8,000 feet in the air. Naturally, its creator has equipped the device with an integrated ballistic parachute.
Purchase Price: US$ 100,000 plus any applicable sales taxes, plus adjustment for inflation as measured by the consumer price index.
