TOSA electric buses use computer models to control costs

By - June 19, 2014 3 Pictures
It’s one thing to invent an electric bus, a hydrogen car, or other green transportation technology, but quite another for it to work in the real world. For example, the Trolleybus Optimisation Système Alimentation (TOSA) flash-charging electric bus system may be the most brilliant idea ever, but if it can’t stay in the black, then might as well be drawn by diesel-powered horses. Scientists at the École Polytechnique Fédérale de Lausanne (EPFL) are hoping to avoid that scenario by developing a computer model that helps engineers integrate the buses into existing transport systems while keeping costs down.

New li-ion battery anode could charge electronics in minutes

By - June 17, 2014 4 Pictures
Researchers at the University of California, Riverside have developed a silicon anode that would allow us to charge lithium-ion batteries up to 16 times faster than is currently possible. The new design relies on a three-dimensional, cone-shaped cluster of carbon nanotubes that could also result in batteries that hold about 60 percent more charge while being 40 percent lighter.

Fractal nanostructures used to build new supermaterials

By - June 6, 2014 3 Pictures
Researchers at the California Institute of Technology are developing a disruptive manufacturing process that combines nanoscale effects and ad-hoc architectural design to build new supermaterials from the ground up. The materials can be designed to meet predetermined criteria such as weighing only a tiny fraction of their macroscopic counterpart, displaying extreme plasticity, or featuring outstanding mechanical strength.

Researchers create flexible wires that could double as batteries

By - June 4, 2014
We literally live in a wired world, with wires snaking hither and yon transmitting electricity and data. Many are visible, while many more are hidden in the walls of buildings, the panels of cars, and the fuselage of aircraft. Now, imagine; what if we were able to turn each and every one of these into a battery that not only transmitted electricity but stored it too? Well, two researchers from the University of Central Florida (UCF) imagined that too, and came up with a way to use nano-technology to make wires with supercapacitance that may eventually also double as batteries.

Scientists create weavable Li-ion fiber battery yarn

By - May 30, 2014 9 Pictures
Scientists at the Fudan University in Shanghai, China, have developed a high-performance Li-ion battery made of carbon nanotube fiber yarns. Roughly one 1 mm in diameter, the fiber shaped lithium-ion batteries are reported lightweight enough to create weavable and wearable textile batteries that could power various devices. The researchers say that the yarn is capable of delivering nearly 71 mAh/g of power, and can also be woven into existing textiles to create novel electronic fabrics. Read More

Structural supercapacitors could make batteries and power cords obsolete

By - May 26, 2014 3 Pictures
Imagine using a mobile phone powered entirely by its casing, or an electric car that runs off power stored in its chassis. Researchers at Vanderbilt University have created a structural supercapacitor that could, they believe, bring this closer to reality, making batteries and power cords obsolete. The structural supercapacitor could make it possible to store energy directly in structural materials, allowing them to deliver power long-term while surviving the real-life mechanical stresses they're bound to experience.
