No more solar wind for Voyager 1 spacecraft
(PhysOrg.com) -- The 33-year odyssey of NASA's Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind.
Astronomers find coldest, driest, calmest place on Earth
The search for the best observatory site in the world has lead to the discovery of what is thought to be the coldest, driest, calmest place on Earth. No human is thought to have ever been there but it is expected to yield ...
Airborne wind turbines to generate power from high winds (w/ Video)
Voyager 1 is leaving the solar system, but the journey continues
At 18.5 billion kilometres from Earth, the Voyager 1 space probe is the most distant human-made object ever to leave our planet.
Greenhouse gases to overpower ozone hole
(PhysOrg.com) -- One set of human-created gases is starting to relinquish its hold on Antarctic climate as another group of emissions produced by human activity is starting to take hold, according to a paper ...
Tilting at wind farms
A way to make wind power smoother and more efficient that exploits the inertia of a wind turbine rotor could help solve the problem of wind speed variation, according to research published in the International Journal of ...
Model shows wind could meet many times world's total power demand by 2030
In 2030, if all energy is converted to clean energy, humans will consume about eleven-and-a-half terawatts of power every year, all sources combined. If there is to be a clean-energy economy based on renewable ...
Power generation is blowing in the wind
(PhysOrg.com) -- By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time.
Galactic magnetic fields may control the boundaries of our solar system
The first all-sky maps developed by NASA's Interstellar Boundary Explorer (IBEX) spacecraft, the initial mission to examine the global interactions occurring at the edge of the solar system, suggest that the galac ...
New evidence to solve the mystery of the 'eclipse wind'
(PhysOrg.com) -- Solar eclipses are not only amazing celestial spectacles - they also cause subtle changes to the weather here on Planet Earth, according to meteorologists.
New 'retention model' explains enigmatic ribbon at edge of solar system
(Phys.org)—The vast edges of our solar system—the boundary at the edge of our heliosphere where material streaming out from the sun interacts with the galactic material—is essentially invisible. It emits ...
Wind speed declining in Pacific Northwest: study
Climate change may be taking some of the wind out of natures sails. A new study led by Simon Fraser University shows evidence of declining wind speeds in areas across the Pacific Northwest.
Higher energy yield with torque vectoring gears
Wind turbines have a problem: Depending on the wind's force, the rotational speed of the turbine and thus of the generator changes. However, alternating current must be fed into the grid with precisely 50 (or 60) hertz. Typically ...
Wind and waves growing across globe: study
(PhysOrg.com) -- Oceanic wind speeds and wave heights have increased significantly over the last quarter of a century according to a major new study undertaken by ANU Vice-Chancellor Professor Ian Young. ...
