NASA Langley Research Center developed a wind event warning technology that provides a practical early warning system (5-10 minutes) for a severe change in the wind vector. Events such as gusts, shear, microbursts,...
In the polymer composites industry, cure cycles are typically developed from trial-and-error or a more effective processing science approach to reduce...
Researchers have developed a fundamentally new type of rotary electrical contact that addresses the two limitations of conventional brush/slip ring technology: 1) short operating lifetime due to sliding-contact...
From airplane wings, to overhead power lines, to the giant blades of wind turbines, a buildup of ice can cause problems ranging from impaired performance all the way to catastrophic...
NASA's Langley Research Center has developed a patented SansEC sensor technology for use in many different areas, including tall structures and wind turbines. The SansEC technology is a proven wireless sensing platform capable of measuring the electrical impedance of physical matter in proximity to the...
Accumulation of insect strikes on the leading edge of airplane wings is a more serious problem than one might realize. Depending on the magnitude, such accumulation changes the aerodynamic characteristics of the wing, causing a change from...
In 1977, the National Renewable Energy Laboratory (NREL, Golden, CO) started as the Solar Energy Research Institute (SERI), spurred by national concern during the 1973 oil embargo that caused long...
Wind and solar energy generation creates challenges, since the Sun only shines by day, and sometimes the wind doesn't blow. Another variability is surges of demand on the grid. On a hot day when air conditioning is in use, utilities must have load-balancing strategies to meet peak demand. A...
Mobile or transportable power supply and distribution systems are needed for various types of work that require electrical power in a field or outdoor environment — such as construction and environmental...
The kinetic turbulence of solar wind originates in the solar corona. The solar wind carries the fluctuations and escapes from the corona along the open magnetic field lines, and enters into the interplanetary space. The energy exchange among waves and particles...
The giant rotor blades are one central part of a wind turbine. Researchers developed a rotor blade that makes more efficient use of large fluctuations in wind strength using...
Located in Argonne, IL, Argonne National Laboratory (ARL) is a multidisciplinary science and engineering research center. Born out of the University of Chicago’s work on the Manhattan Project in...
Wind power has become an indispensable part of an environmentally friendly power supply. Therefore, it is important for this growth market that wind turbines become more efficient, more...
A new flow battery from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) stores energy in organic molecules dissolved in neutral pH water. Losing only one percent of its capacity per 1000 cycles, the non-toxic, non-corrosive device offers the potential to...
Iowa State University scientists have built a device that mimics the branches and leaves of a cottonwood tree and generates electricity when its artificial leaves sway in the wind. The device is derived...
Texas Tech University scientists have brought the wind power industry one step closer to its potential with the creation of a system to measure wind flow and control...
A team of scientists from Oxford University has shown how the natural movement of bacteria could be harnessed to assemble and power microscopic "windfarms."
On your car windshield, ice is a nuisance. But on an airplane, wind turbine, oil rig, or power line, it can be downright dangerous. And removing it with the methods...
Testing has started at NASA on a concept called the Heliopause Electrostatic Rapid Transit System (HERTS), a propellant-less propulsion system that would harness solar wind to travel...
A new design for gigantic blades longer than two football fields could help bring offshore 50-megawatt (MW) wind turbines to the United States and the world. Sandia National...
Engineers from the University of Sheffield have developed a novel technique to predict when bearings inside wind turbines will fail, which could make wind energy cheaper. The method uses...
Large wind turbine blades disturb the wind, creating a wake behind them and reducing the energy harvest of any downwind turbines. A turbine sitting in the slipstream of another can...
