High-altitude wind turbines have potential to generate large amounts of electricity
(Phys.org) —Wind turbines hovering high in the air and tethered to the ground, like kites, have the potential to generate huge amounts of electricity, based on a recent wind availability study led by the ...
When the wind blows: New wind energy research focuses on turbine arrangement, wind seasonality
(Phys.org) —Research into the best ways to arrange wind turbines has produced staggering results—quite literally.
Personality clue to 'wind turbine syndrome'
(Phys.org) —Public concern about new technology infrastructure like mobile phone masts has been shown to trigger reports of ill health… and recently even the new 'green' technology of wind turbines has ...
Bat's sea crossing is first from UK to mainland Europe
(Phys.org) —A tiny bat found in the Netherlands is believed to provide the first direct evidence that British bats migrate over the sea between the UK and mainland Europe.
Wind power blows into Africa
Giant turbines churning in the wind are a rare sight in Africa—but that will not be the case for long. Until now the meagre amounts of investment in African wind energy have predominantly come from governments ...
Clean energy could lead to scarce materials
As the world moves toward greater use of low-carbon and zero-carbon energy sources, a possible bottleneck looms, according to a new MIT study: the supply of certain metals needed for key clean-energy technologies.
New research blows away claims that aging wind farms are a bad investment
Wind turbines can remain productive for up to 25 years, making wind farms an attractive long-term choice for energy investors, according to new research.
Hitachi unveils motor without 'rare earths'
Japanese high-tech firm Hitachi Wednesday unveiled an electric motor that does not use "rare earths", aiming to cut costs and reduce dependence on imports of the scarce minerals from China.
Highly active catalysts could be key to improved energy storage in fuel cells and advanced batteries
MIT researchers have found a new family of materials that provides the best-ever performance in a reaction called oxygen evolution, a key requirement for energy storage and delivery systems such as advanced ...
Storing wind-generated electricity as fuels means catalysts must avoid low energy states
When it comes to driving reactions to store electrons from wind turbines in the chemical bonds of use-any-time fuels, the path the catalyst takes matters. Researchers want to avoid low-energy and high-energy ...
Space likely for rare earths search, scientists say
The quest for rare earths vital to some of modern life's most indispensable technologies may see mining robots jet to the stars within decades, a world-first conference in Australia was told Wednesday. ...
The secrets of owls' near noiseless wings
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.
Delft professor puts kites high on list for renewable energy
Study determines best arrangement of tidal sails device
In the long sprint to find new sources of clean, low-cost power, slow and steady might win the race—the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing ...
