Breakthrough iron-based superconductors set new performance records
(Phys.org)—The road to a sustainably powered future may be paved with superconductors. When chilled to frigid temperatures hundreds of degrees Celsius below zero, these remarkable materials are singularly ...
Thrusters powered by ionic wind may be efficient alternative to conventional atmospheric propulsion technologies
When a current passes between two electrodes—one thinner than the other—it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of ...
Researchers suggest high energy emissions from Crab Nebula come from wind
High-tech cargo airship being built in California (Update)
The massive blimp-like aircraft flies but just barely, hovering only a dozen feet off a military hangar floor during flight testing south of Los Angeles.
Chasing clouds on Venus
(Phys.org)—Clouds regularly punctuate Earth's blue sky, but on Venus the clouds never part, for the planet is wrapped entirely in a 20 km-thick veil of carbon dioxide and sulphuric dioxide haze.
Wind pushes plastics deeper into oceans, driving trash estimates up
(Phys.org) -- While working on a research sailboat gliding over glassy seas in the Pacific Ocean, oceanographer Giora Proskurowski noticed something new: The water was littered with confetti-size pieces of ...
Wind turbines that learn like humans
Depending on the weather, wind turbines can face whispering breezes or gale-force gusts. Such variable conditions make extracting the maximum power from the turbines a tricky control problem, but a collaboration of Chinese ...
Cluster mission indicates turbulent eddies may warm the solar wind
(Phys.org)—The sun ejects a continuous flow of electrically charged particles and magnetic fields in the form of the solar wind—and this wind is hotter than it should be. A new study of data obtained ...
Japanese Team Tokai wins the 3,021 km 2011 Veolia World Solar Challenge
New 'core wall' may speed skyscraper construction
Researchers are perfecting a new technique that could speed construction of skyscrapers while also providing enough stiffness and strength to withstand earthquakes and forces from high winds.
The high winds of the upper atmosphere contain less renewable energy than previously assumed
It seems that the energy mix of the future will have to differ from the current suggestions of some visionaries. This is because the jet streams that sweep the upper atmosphere with high winds would yield ...
Watching Venus glow in the dark
(PhysOrg.com) -- ESA’s Venus Express spacecraft has observed an eerie glow in the night-time atmosphere of Venus. This infrared light comes from nitric oxide and is showing scientists that the atmosphere ...
Winds force cancellation of unmanned rocket launch
A company contracted by the U.S. space agency to deliver supplies to the International Space Station has cancelled the launch of a test rocket.
Using magnetism to understand superconductivity
Swiss research in atomic scale magnetism could play a role in the development of new materials that could permit lossless electricity transmission.
