DOE explores potential of wind to stabilize grids

Jim Ahlgrimm has been a manager in the U.S. Department of Energy Wind and Water Power Technologies Office since 2002

When the U.S. Department of Energy (DOE) commissioned a 1.5-megawatt (MW) wind turbine in 2009, it became a key player in our research to improve the performance and lower the costs of wind energy systems. In 2015, researchers at the National Wind Technology Center (NWTC) near our National Renewable Energy Laboratory

Google ATAP and Infineon advance their partnership in Soli radar tech

One day products may be controlled exclusively through gestures

For the first time, two prototypes of products controlled exclusively through gestures were demonstrated at “Google I/O”, a smartwatch and a wireless speaker. Both devices can recognize gestures that replace switches or buttons with this revolutionary concept. Infineon Technologies and Google ATAP enabled

JSAP researches spin currents at metal-oxide interfaces for magnetic memories

Top: Fermi contours with Rashba splitting, and non-equilibrium spin accumulation resulting from a shift of Fermi contours by spin injection. Bottom left: Experimental setup for the spin pumping measurement. Bottom right: Schematic of spin-to-charge current conversion at the Cu/Bi2O3 interface. Spin currents are generated by spin pumping from a Py layer in ferromagnetic resonance to a Cu layer and reach a Cu/Bi2O3 interface. Then, the spin-to-charge current conversion occurs owing to the spin-momentum locking at the Rashba interface.

Devices based on spin currents rather than charge currents, offer interesting technological opportunities, such as future high-density, ultrafast and low-power magnetic memory devices. Conversion between charge and spin currents is key for exploiting such “spintronics”. Researchers at the University of Tokyo

First rechargeable sodiumâ€

The sodium–carbon dioxide battery could power vehicles in Mars' CO2-rich atmosphere or recycle exhaust CO2 in a hybrid car

The first rechargeable sodium–carbon dioxide battery has been created with the help of a nanostructured cathode. The cheap and potentially powerful battery could fuel Mars vehicles as the red planet’s atmosphere is 96% carbon dioxide or recycle carbon dioxide emissions on Earth. Sodium–carbon

IEEFA says wind on the rise, coal on the wane

Energy split in the US

As coal dependence falters in the U.S., wind-powered electricity generation is on the rise. In less than a decade, the mix of fuels used for generating electricity has gone a major shift. Twelve states, most of them in the wind-rich Great Plains or the upper Midwest, are getting more than 10 percent of their

Pohang University researchers create advanced miniaturized fuel cell

Prof. Choi and his Ph.D. student Kun Joong Kim

Drones are used for various applications such as aero picturing, disaster recovery, and delivering. Despite attracting attention as a new growth area, the biggest problem of drones is its small battery capacity and limited flight time of less than an hour. A fuel cell developed by Pohang University's Prof. Gyeong
