New Scientist TV: Giant 3D loom weaves parts for supercar - 0 views

  •  
    It's a sports car few people will be able to get their hands on. In production since last December, only 500 Lexus LFAs will be produced and they were already sold out in early June 2010 (see photo below). But it's not just its top speed of 325 kilometres per hour that's attracting buyers. The car is being used as a test bed for newly-designed parts made from carbon fibre and plastic. Compared to steel or aluminium, it makes the car stronger and lighter but producing these components is much more time-consuming: only one car is currently being assembled per day. One of the key technologies being used is a high-tech circular loom, guided by lasers, that can weave 3D objects (see video above). The machine's futuristic design attracted lots of media attention two years ago, but the video was pulled for fear it would expose company secrets. Now Lexus is revealing how the loom is being used to create complex 3D parts with varying thicknesses and curved shapes. For example, it can create roof rails by weaving fibres around a core, two layers at time, until twelve layers later a hollow roof rail is produced. The piece can then be moulded and injected with resin to create the finished part. The machine was also used to create the car's chassis and front pillars as well as the steering wheel.

New way to store solar energy for use whenever it's needed | KurzweilAI - 0 views

  •  
    MIT researchers have developed a new application of carbon nanotubes that shows promise as an innovative approach to storing solar energy for use whenever it's needed. Storing the sun's heat in chemical form - rather than first converting it to electricity or storing the heat itself in a heavily insulated container - has significant advantages: in principle, the chemical material can be stored for long periods of time without losing any of its stored energy. The researchers created carbon nanotubes in combination with a compound called azobenzene. The resulting molecules, produced using nanoscale templates to shape and constrain their physical structure, and the concept that can be applied to many new materials. This material is vastly more efficient at storing energy in a given amount of space - about 10,000 times higher in volumetric energy density, making its energy density comparable to lithium-ion batteries, the researchers said.

Medical devices powered by the ear itself - MIT News Office - 0 views

  • Health Sciences and Technology (HST) demonstrate for the first time that this battery could power implantable electronic devices without impairing hearing.
  • The devices could monitor biological activity in the ears of people with hearing or balance impairments, or responses to therapies. Eventually, they might even deliver therapies themselves
  • “In the past, people have thought that the space where the high potential is located is inaccessible for implantable devices, because potentially it’s very dangerous if you encroach on it,” Stankovic says. “We have known for 60 years that this battery exists and that it’s really important for normal hearing, but nobody has attempted to use this battery to power useful electronics.”

  • The ear converts a mechanical force — the vibration of the eardrum — into an electrochemical signal that can be processed by the brain; the biological battery is the source of that signal’s current. Located in the part of the ear called the cochlea, the battery chamber is divided by a membrane, some of whose cells are specialized to pump ions. An imbalance of potassium and sodium ions on opposite sides of the membrane, together with the particular arrangement of the pumps, creates an electrical voltage.
  • Low-power chips, however, are precisely the area of expertise of Anantha Chandrakasan’s group at MTL
  • The frequency of the signal was thus itself an indication of the electrochemical properties of the inner ear.
  • in cochlear implants, diagnostics and implantable hearing aids. “The fact that you can generate the power for a low voltage from the cochlea itself raises the possibility of using that as a power source to drive a cochlear implant,” Megerian says. “Imagine if we were able to measure that voltage in various disease states. There would potentially be a diagnostic algorithm for aberrations in that electrical output.”
  • “I’m not ready to say that the present iteration of this technology is ready,” Megerian cautions. But he adds that, “If we could tap into the natural power source of the cochlea, it could potentially be a driver behind the amplification technology of the future.”
  •  
    "For the first time, researchers power an implantable electronic device using an electrical potential - a natural battery - deep in the inner ear."

    "All of D-Lab's classes assess the needs of people in less-privileged communities around the world, examining innovations in technology, education or communications that might address those needs. The classes then seek ways to spread word of these solutions - and in some cases, to spur the creation of organizations to help disseminate them. Specific projects have focused on improved wheelchairs and prosthetics; water and sanitation systems; and recycling waste to produce useful products, including charcoal fuel made from agricultural waste."

New Scientist TV: Amputees regain control with bionic arm wired to chest - 0 views

  •  
    Jesse Sullivan, the man in this video, is using one of the most high-tech prosthetic arms available. But what's truly impressive about it isn't visible to the eye: instead of using a motor, he's controlling the arm with his thoughts. After an amputation, the nerves in a stump remain healthy, at least for a while, and now scientists are making use of this fact to create highly dexterous, thought-controlled prosthetics.

Stamping out low-cost nanodevices | KurzweilAI - 0 views

  •  
    A simple technique for stamping patterns invisible to the human eye onto a special class of nanomaterials has been developed by researchers at Vanderbilt University. The new method works with porous nanomaterials that are riddled with tiny voids, which give them unique optical, electrical, chemical, and mechanical properties. There are nanoporous forms of gold, silicon, alumina, and titanium oxide, among others. The technique involves the creation of pre-mastered stamps using traditional, but complex, clean room processes and then using the stamps to create patterns using a new process called direct imprinting of porous substrates (DIPS). DIPS can create a device in less than a minute, regardless of its complexity. The smallest pattern the researchers have made to date has features of only a few tens of nanometers (about the size of a single fatty acid molecule). They have also succeeded in imprinting the smallest pattern yet reported in nanoporous gold, one with 70-nanometer features. The first device the group has created is a "diffraction-based" biosensor that can be configured to identify a variety of different organic molecules, including DNA, proteins and viruses. The researchers envision a wide range of applications including drug delivery, chemical and biological sensors, solar cells, and battery electrodes.

Hybrid solar system makes rooftop hydrogen | KurzweilAI - 0 views

  •  
    Duke University engineer Nico Hotz has proposed a hybrid solar system in which sunlight heats a combination of water and methanol in a maze of tubes on a rooftop to produce hydrogen. The device is a series of copper tubes coated with a thin layer of aluminum and aluminum oxide and partly filled with catalytic nanoparticles. A combination of water and methanol flows through the tubes, which are sealed in a vacuum. Once the evaporated liquid achieves higher temperatures, tiny amounts of a catalyst are added, which produces hydrogen. This combination of high temperature and added catalysts produces hydrogen very efficiently, Hotz said. The resulting hydrogen can then be immediately directed to a fuel cell to provide electricity to a building during the day, or compressed and stored in a tank to provide power later. After two catalytic reactions, the system produced hydrogen much more efficiently than current technology without significant impurities, Hotz said. The resulting hydrogen can be stored and used on demand in fuel cells. "This set-up allows up to 95 percent of the sunlight to be absorbed with very little being lost as heat to the surroundings," he said. "This is crucial because it permits us to achieve temperatures of well over 200 degrees Celsius within the tubes. By comparison, a standard solar collector can only heat water between 60 and 70 degrees Celsius." Holtz performed a cost analysis, comparing a standard photovoltaic cell, a photocatalytic system, and the hybrid solar-methanol system.  He found that the hybrid system is the least expensive solution, with a total installation cost of $7,900 if designed to fulfill the requirements in summer. The paper describing the results of Hotz's analysis was named the top paper during the ASME Energy Sustainability Fuel Cell 2011 conference in Washington, D.C.

New engine shakes up auto industry - Technology & science - Innovation - msnbc.com - 0 views

  •  
    Despite shifting into higher gear within the consumer's green conscience, hybrid vehicles are still tethered to the gas pump via a fuel-thirsty 100-year-old invention: the internal combustion engine. However, researchers at Michigan State University have built a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids. Their so-called Wave Disk Generator could greatly improve the efficiency of gas-electric hybrid automobiles and potentially decrease auto emissions up to 90 percent when compared with conventional combustion engines. The engine has a rotor that's equipped with wave-like channels that trap and mix oxygen and fuel as the rotor spins. These central inlets are blocked off, building pressure within the chamber, causing a shock wave that ignites the compressed air and fuel to transmit energy. The Wave Disk Generator uses 60 percent of its fuel for propulsion; standard car engines use just 15 percent. As a result, the generator is 3.5 times more fuel efficient than typical combustion engines. Researchers estimate the new model could shave almost 1,000 pounds off a car's weight currently taken up by conventional engine systems. Last week, the prototype was presented to the energy division of the Advanced Research Projects Agency, which is backing the Michigan State University Engine Research Laboratory with $2.5 million in funding. Michigan State's team of engineers hope to have a car-sized 25-kilowatt version of the prototype ready by the end of the year.

Scientists investigate using artificial intelligence for next-generation traffic control - 0 views

  • The research carried out by the University of Southampton team has used computer games and simulations to investigate what makes good traffic control. This work has shown that – given the right conditions – humans are excellent at controlling the traffic and can perform significantly better than the existing urban traffic control computers in use today.
  • The Southampton researchers have now developed 'machine learning' traffic control computers that can learn how to control the lights like a human would and even learn their own improved strategies through experience.
