World’s first 100 percent biofuel-powered flight of civil aircraft

World’s first 100 percent biofuel-powered flight of civil aircraft: "Earlier this year, Air Canada joined a growing number of airlines conducting flights using biofuels. Like similar flights by Boeing and Lufthansa, the aircraft was powered by a mix of petroleum and biofuel. Now the National Research Council of Canada (NRC) has removed the fossil fuel component completely with the first flight of a civil jet powered by 100 percent unblended biofuel."

How to boost lithium battery performance – just add crushed silicon

How to boost lithium battery performance – just add crushed silicon: "Researchers at Rice University and Lockheed Martin may have developed a low-cost method of creating longer-lasting, high-capacity lithium-ion batteries. Currently graphite is used as the anode in commercial li-ion products, despite the fact that a silicon anode could potentially store ten times more lithium ions. The team says it has solved one of the problems associated with silicon, which nearly triples the energy density of current li-ion designs."

TechJect’s Dragonfly micro UAV flies like a bird and hovers like an insect

TechJect’s Dragonfly micro UAV flies like a bird and hovers like an insect: "Given their impressive flight capabilities, it’s not surprising to see researchers turning to the world of flying insects for inspiration when developing new kinds of micro UAVs. With their ability to both fly at high speeds and hover, the dragonfly would seem an obvious candidate for biomimicry."

Cloaking technology could protect offshore rigs from destructive waves

Cloaking technology could protect offshore rigs from destructive waves: "Recent years have seen much progress in the development of invisibility cloaks which bend light around an object so it can't be seen, but can the same principles be applied to ocean waves that are strong enough to smash steel and concrete? That's the aim of Reza Alam's underwater “invisibility cloak.” The assistant professor of mechanical engineering at the University of California, Berkeley, recently outlined how to use variations of density in ocean water to cloak floating objects from dangerous surface waves."

2013 SRT Viper set for production

2013 SRT Viper set for production: "It was only a few short months ago that Chrysler showed off the 2013 SRT Viper at the New York Motor Show. The brand new model boasts some serious refinements over previous iterations of the 10-cylinder beast, with the body style and interior rebuilt from the ground up. The muscle-car is now set to enter production, and the company has released some new performance numbers and an extensive photo gallery to mark the occasion."

SAVMS: prefab modular housing in under 3 weeks?

SAVMS: prefab modular housing in under 3 weeks?: "Madrid-based architectural studio CSO Arquitectura teamed up with prefab construction specialists Torsan to create SAVMS, a modular housing system designed to maximize adaptability while minimizing ecological footprint. The flexibility of the system allows customers to choose a house of their own design, while the prefabricated approach allows costs to be kept more or less fixed."

South Korea develops bird strike defense robot

South Korea develops bird strike defense robot: "The Korean Atomic Energy Group and LIG Nex1 (an aerospace and defense subsidiary of LG Corp) have jointly developed what they are calling the world's first bird strike defense robot. Birds are a major headache around military air bases and civilian airports all over the world, as they can cause significant damage when they collide with aircraft or get sucked into engines. The robot is a six-wheeled unmanned ground vehicle (UGV) that uses a combination of directional acoustics and laser patterns to scare birds away."

Hubble discovers most distant galaxy ever observed

Hubble discovers most distant galaxy ever observed: "NASA's Hubble telescope has discovered the most distant object yet seen in the universe. The object, a galaxy called MACS0647-JD, is 13.3 billion light years from Earth and can only be seen with the help of a lens of intergalactic proportions. The light from MACS0647-JD left it only 420 million years after the Big Bang, so it provides a valuable look into the nature of the early universe."
