New Study Uses Blizzard to Measure Wind Turbine Airflow

A study by researchers at the University of Minnesota using snow during a Minnesota blizzard is giving researchers new insight into the airflow around large wind turbines. This research is essential to improving wind energy efficiency, especially in wind farms where airflows from many large wind turbines interact with each other. As wind turbines have grown to more than 100 meters tall, field research in real-world settings has become more difficult.

Gas Flow Measurement Technology Packs Hundreds of Sensors Into One Optical Fiber

By fusing together the concepts of active fiber sensors and high-temperature fiber sensors, a team of researchers at the University of Pittsburgh has created an all-optical high-temperature sensor for gas flow measurements that operates at record-setting temperatures above 800 °C. This technology is expected to find industrial sensing applications in harsh environments ranging from deep geothermal drill cores to the interiors of nuclear reactors to the cold vacuum of space missions, and it may eventually be extended to many others.

New Supercapacitor Could Make Structural Energy Storage A Reality

Imagine a future in which our electrical gadgets are no longer limited by plugs and external power sources. This intriguing prospect is one of the reasons for the current interest in building the capacity to store electrical energy directly into a wide range of products, such as a laptop whose casing serves as its battery, or an electric car powered by energy stored in its chassis, or a home where the dry wall and siding store the electricity that runs the lights and appliances. It also makes the small, dull grey wafers that graduate student Andrew Westover and Assistant Professor of Mechanical Engineering Cary Pint have made in Vanderbilt's Nanomaterials and Energy Devices Laboratory far more important than their nondescript appearance suggests.

Big Ideas for Small Spaces

Over 24 hours from April 4 to 5, six top French design studios conceived and presented new product concepts for urban environments during the Small Spaces Design Hackathon, presented by Cut&Paste in partnership with Hewlett-Packard. In dense city neighborhoods, homes are small and office space is at a premium, so urban dwellers must be more creative in how they use their space. The design concepts were presented at Cyclone Le Studio as part of ZED, HP’s creative popup space.

Aircraft Engine Coating Could Triple Service Life and Save Fuel

Researchers at University West in Sweden are using nanoparticles in the heat-insulating surface layer that protects aircraft engines from heat. In tests, this increased the service life of the coating by 300%. The hope is that motors with the new layers will be in production within two years. The surface layer is sprayed on top of the metal components. Thanks to this extra layer, the engine is shielded from heat. The temperature can also be raised, which leads to increased efficiency, reduced emissions, and decreased fuel consumption.

Switchable Material Absorbs and Stores Sun's Energy

A team at MIT and Harvard University has created a material that absorbs the sun’s heat and stores that energy in chemical form, ready to be released again on demand.The technology provides an opportunity for the expansion of solar power into new realms, specifically applications where heat is the desired output.“It could change the game, since it makes the sun’s energy, in the form of heat, storable and distributable,” says Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT.SourceAlso: See other Materials tech briefs.
