Drought Solution Could Be Blowing In The Wind
Generating rainfall for deserts using wind power and seawater is the subject of a new research project. The idea involves the installation at sea of specially designed wind turbines. The turning motion of the rotors would be harnessed to pump seawater along the turbines' hollow blades. The water would then be forced out through slits as a fine... view more... (2002-11-04)
Answers to huge wind-farm problems are blowin' in the wind
While harnessing more energy from the wind could help satisfy growing demands for electricity and reduce emissions of global-warming gases, turbulence from proposed wind farms could adversely affect the growth of crops in the surrounding countryside. view more (2008-12-17)
The power of multiples: Connecting wind farms can make a more reliable - and cheaper - power source
Wind power, long considered to be as fickle as wind itself, can be groomed to become a steady, dependable source of electricity and delivered at a lower cost than at present, according to scientists at Stanford University. view more (2007-11-26)
Renewable energy wrecks environment
Renewable does not mean green. That is the claim of Jesse Ausubel of the Rockefeller University in New York. Writing in Inderscience's International Journal of Nuclear Governance, Economy and Ecology, Ausubel explains that building enough wind farms, damming enough rivers, and growing enough biomass to meet global energy demands will wreck the... view more...

Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
Virtually engineering power plants
Photovoltaic and wind energy plants, hydroelectric power stations and biogas plants supply energy without polluting the environment. However, they are complex to design and maintain. Virtual reality (VR) makes planning and operation easier. view more (2009-07-14)
Wind power explored off California's coast
In many ways, wind energy seems an ideal energy source. Fields of mighty turbines spinning in rhythm could harness carbonless power and shuttle it off to homes and industries. view more (2007-12-13)
Light from wind and waves
Engineers of PROEKTSTROYSERVIS (Kaliningrad) know how to make the stormy sea work. They have designed a unique sea-based wind-and-wave plant, which allows to convert the energy of wind and waves into electricity. The plant is not afraid of any storms. In appearance, the entire construction is reminiscent of a float, UFO or the restaurant in the... view more... (2003-08-22)
TU Delft tests windmill for seawater desalination
A traditional windmill which drives a pump: that is the simple concept behind the combination of windmill/reverse osmosis developed by the Delft University of Technology (TU Delft) in The Netherlands. In this case, it involves a high-pressure pump which pushes water through a membrane using approximately 60 bar. This reverse osmosis membrane... view more... (2008-03-03)
Deep-sea oil rigs inspire MIT designs for giant wind turbines
An MIT researcher has a vision: Four hundred huge offshore wind turbines are providing onshore customers with enough electricity to power several hundred thousand homes, and nobody standing onshore can see them. view more (2006-09-19)
New Carbon Material Shows Promise of Storing Large Quantities of Renewable Electrical Energy
Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar... view more...

Shifting the world to 100 percent clean, renewable energy as early as 2030 -- here are the numbers
Most of the technology needed to shift the world from fossil fuel to clean, renewable energy already exists. Implementing that technology requires overcoming obstacles in planning and politics, but doing so could result in a 30 percent decrease in global power demand. view more (2009-10-20)
Stock Market Swings Help Researchers Understand Extreme Events in Solar Wind
Astrophysicists at the University of Warwick have applied data analysis methods used to model stock market fluctuations, to explore changes in the solar wind (the sun's expanding atmosphere). They have discovered that the fluctuations in the solar wind follow the same kinds of patterns seen in the stock markets - particularly when it comes to the... view more... (2002-07-25)
Key issues for the future of wind energy
The prestigious journal Energy Policy has recently reported two studies that highlight some key issues for the future of wind energy in Spain. view more (2009-09-08)
Researchers find substantial wind resource off Mid-Atlantic coast
The wind resource off the Mid-Atlantic coast could supply the energy needs of nine states from Massachusetts to North Carolina, plus the District of Columbia—with enough left over to support a 50 percent increase in future energy demand—according to a study by researchers at the University of Delaware and Stanford University. view more (2007-02-02)
Why wind turbines can mean death for bats
Power-generating wind turbines have long been recognized as a potentially life-threatening hazard for birds. But at most wind facilities, bats actually die in much greater numbers. view more (2008-08-26)
Hinode: new insights on the origin of solar wind
Spectacular images and data from the Hinode mission have shed new light on the Sun's magnetic field and the origins of solar wind, which can disrupt power grids, satellites and communications on Earth. view more (2007-12-10)
Hinode reveals new insights about the origin of solar wind
Images from NASA-funded telescopes aboard a Japanese satellite have shed new light about the sun's magnetic field and the origins of solar wind, which disrupts power grids, satellites and communications on Earth. view more (2007-12-07)
NJIT architect professor advocates best-building practices for high wind regions
More than ever before, building design and construction can be significantly improved to reduce wind pressures on building surfaces and to help better resist high winds and hurricanes in residential or commercial construction, said NJIT architecture professor Rima Taher, PhD. view more (2008-07-10)
U of C scientists find successful way to reduce bat deaths at wind turbines
Scientists at the University of Calgary have found a way to reduce bat deaths from wind turbines by up to 60 percent without significantly reducing the energy generated from the wind farm. view more (2009-09-28)
