The scientists know that a bacterium of Shewanella oneidensis living in depths of oceans is capable to develop an electric current at contact with heavy metals. The scientists from the University of East Asia start the new research directed on studying of how bacteria develop electricity, when proteins in cellular membranes contact to a mineral surface. This study is an important step in a way of creation bio-batteries. For the production the necessary quantity of energy for life of bacterium, the proteins can “transport” electrons through a membrane in a high speed. Just as people breathe oxygen and use it for generation of energy, bacterium of Shewanella can use minerals, like iron oxide, for breath. According to the scientists, they know the movement of bacteria’s electrons through cellular membranes, but the transformation of electrons from bacteria into the minerals, still is not clearly for them.
Yesterday (on March 17) at an official press conference of investors in Volsfburge, company Volkswagen opened some details of the Volkswagen electric car e-up. It was presented for the first time. The novelty is equipped with a 81-strong electric motor and a set lithium – ion batteries of 18,7 kWh. Range of run of this electric car makes 150 kilometers. The Volkswagen electric car e-up can be equipped with according to the buyers’ desire. After the storage battery is completely charged, it is possible to recharge it during a way for 80% in 30 minutes. The Volkswagen e-up electric car practically differs nothing from the petrol relative, however nevertheless has some specific elements. For example, the car is equipped with LED day headlights on a front bumper.
According to UK Ministry of Defense British Forces in Afghanistan received miniature spy drone, 16 gram helicopter Black Hornet Nano up to 10 centimeters in length and two and a half in width. Black Hornet Nano is equipped with a miniature camera that can transmit both video and photos. Despite its compact size Black Hornet Nano is capable of operating in critical weather conditions. According to BBC News, the device is equipped with a battery and can cover up to 800 feet in the air or up to 30 minutes. As reported BBC News, in the total of the British military Department has ordered 160 Black Hornet Nano to 20 million pounds sterling (31,5 million dollars). Using the helicopters in Afghanistan began in 2012.
Design Studio Skyrill, located in the capital Manama, Bahrain, presented Jaguar XKX Roadster Concept designed by the legendary sports car Jaguar E-Type 1961 release. Brothers Ali and Hussein Almossavi, owners of an independent design studio Skyrill, located in the capital Manama, Bahrain, in collaboration with the Albanian designer Marina Muftii introduced the concept of Jaguar XKX, which is based on the known model of Jaguar E-Type, launched into production back in 1961, and became one of the automotive legends. Jaguar E-Type (or Jaguar XK-E) is very successful for its time, sports “supercar”. Given a much smaller and cooler power plant than conventional, the aerodynamics was conceived in a new innovative way. The side deflector intakes of the front were made broader, so a much larger amount of air does not get stuck by the engine, instead, it flows behind the front wheels, getting out behind them and sliding along the doors and then taking another shortcut through the rear wheels and out from the big rear openings, greatly reducing the total flowing path and subsequently drag. Almost 60% of the energy used by a typical car at highway speeds is spent to counter air friction. Obviously, that is A LOT of energy spent for a function that is indispensable, but not the primary (to push the vehicle forward).
Samsung has launched its Galaxy S III smartphone, which it hopes will help solidify the company as the leading challenger to Apple and its iPhone 4S. The new smartphone, with a whopping 4.8-inch screen and an 8-megapixel camera, was unveiled at a slick launch party in London on Thursday. Billed by Samsung as having been designed for humans, the phone features voice and eye-recognition technology that the company hopes will set the handset ahead of its rivals in the crowded smartphone market.
Volta Volaré has begun taking orders for its four-seater GT4 hybrid private aircraft it calls the most technologically advanced private aircraft available anywhere on Earth. Though the GT4 is perfectly capable of taking off and flying powered only electrically, a gas engine starts when the airplane’s battery drops to 25 percent capacity in order to recharge it mid-flight. Surprisingly, perhaps, Volta Volaré makes a strong economic case for the GT4.
Boston Dynamics, creator of the very awesome BigDog and a menagerie of other bots, is sending two small reconnaissance robots to the U.S. Army for testing. Sand Flea and RHex, developed with funding from the Army’s Rapid Equipping Force, are off to the Army Test and Evaluation Command (ATEC) to pass safety and reliability assessments.Three RHex units have already been delivered to ATEC and Sand Fleas will join them later this year, Boston Dynamics said in a release.
General Motors (GM) and NASA team up to create a robotic glove that auto workers and astronauts can wear to help do their respective jobs better while potentially reducing the risk of repetitive stress injuries. The Human Grasp Assist device, known internally in both organizations as the K-glove or Robo-Glove, resulted from GM and NASA’s Robonaut 2 (R2) project, which launched the first human-like robot into space in 2011.
The new iPad unveiled Wednesday comes with improvements that may not be readily apparent to the casual observer. It has, as expected, a sharper screen, driven by a faster processing chip that acts as the “brains” of the device. What was more surprising was that the new features mean the tablet computer will be slightly thicker and heavier than the iPad 2, because it needs a larger battery to power the high-resolution screen. Apple gave the new iPad a bunch of new features but no new name. It will be “the iPad” or perhaps “the new iPad”, not “iPad 3” or “iPad HD,” as some had speculated. Prices aren’t changing from the previous models.
