Molecules Could Harvest Sunshine for a Rainy Day

The Sun is a huge source of energy. In just one hour, planet Earth is hit by so much sunshine that humankind could cover its energy needs for an entire year if only we knew how to harvest and save it. A student at the University of Copenhagen has researched his way to a breakthrough that may prove pivotal for technologies trying to capture the energy of the Sun, and saving it for a rainy day.

Electrical Power Converter Accepts Power from Renewable Energy

Engineering researchers at the University of Arkansas have invented a novel electrical power converter system that simultaneously accepts power from a variety of energy sources and converts it for use in the electrical grid system. The U.S. Department of Energy is seeking licensing opportunities for potential commercialization.

Stratasys Extends Accessibility of Unique Triple-Jetting 3D Printing Technology with the Connex 1,2, and 3

Stratasys' triple-jetting technology is unique, allowing users to build products with up to three base materials in a single run, forming new Digital Materials such as Digital ABS or producing parts in vibrant colors. This technology 3D prints parts in a single, automated build with up to 80 material properties per part, ranging from rigid to rubber-like in a range of vibrant colors and a range of Shore A values producing exceptional final-product realism. The PolyJet Connex technology can create smooth, detailed, accurate molds.

Researchers Create Acoustic 'Image' of Thunder

Southwest Research Institute (SwRI) researchers have imaged the first acoustic signature of thunder, visually capturing the sound waves created by artificially triggered lightning.While the general mechanics of thunder generation are understood, it is not particularly clear which physical processes of the lightning discharge contribute to the thunder we hear. By studying the acoustic power radiated from different portions of the lightning channel, researchers can learn more about the origins of thunder as well as the energetic processes associated with lightning.  Dr. Maher A. Dayeh, a research scientist in the SwRI Space Science and Engineering Division, designed a large, sophisticated array of microphones to study the acoustic signature of thunder. Fifteen microphones, spaced one meter apart, were lined up 95 meters away from the rocket launch pad where the triggered lightning would strike. To image the vertical profile of the bolt, Dayeh used post-signal processing techniques and directional amplification of the data signals captured by the microphone array. The technique revealed a distinct signature of thunder generated by the lightning strike. Future experiments could allow scientists to study the probable acoustic signatures of current pulses, step leader branches, and discharge channel zigzags independently.SourceLearn about an Accelerometer Sensors Network for Acoustic Diagnostics (MASNAD).

Will "smart city" lighting efforts pay off?

This week's Question: At this year's Mobile World Congress in Spain, Sierra Wireless and Philips CityTouch demonstrated "smart city" lighting capabilities. The companies' systems connect a city's individual street lights to the Internet via 2G, 3G, and 4G networks. The "smart" technology allows authorities to create customized lighting patterns and adjust the lamps for specific weather conditions or neighborhood needs. With "smart city" designs, users will potentially gain a clearer picture of a city’s lighting infrastructure, access real-time data on energy consumption, and receive automatic failure notifications, ultimately reducing costs in both energy and maintenance. To achieve this type of connected city, however, a common set of standards must enable interoperability so that every application can communicate and share data. Security levels, too, must be maintained. What do you think? Will "smart city" lighting efforts pay off?

From Tires to Interiors, Bentley Designs with 3D Printing

When your very name conjures up visions of luxury, quality, and detail, your design studio has to employ the very best minds working with the very best technology. Founded from modest beginnings in England in 1919, Bentley Motors Ltd. is dedicated to making responsive and powerful Grand Tourer automobiles with the stamina to cross continents at speed, in refined comfort and style. Little surprise then, that Bentley should equip its design studio with Objet30 Pro desktop and Objet500 Connex multi-material 3D printers.

Revolutionizing Manufacturing With 3D Printing

With traditional manufacturing methods, it's not practical to manufacture a single item or short run of products — it's simply too expensive, in terms of both time and money. Securing factory space, setting up a production line, and procuring jigs and fixtures all incur substantial costs that can't be justified for a few items.
