New technology may reduce wind energy costs

London, Aug 15 (IANS) The efficiency of wind turbines can be increased and repair costs reduced through a new technique developed by engineers from the University of Sheffield. The novel technique can predict when bearings inside wind turbines fail which could make wind energy cheaper. Unexpected bearing failures are a common problem in wind turbines. By removing the risk...

US military developing hypersonic jet

Washington, July 6 (IANS) Giving more teeth to its combat prowess, the US military is reportedly developing a hypersonic jet plane that could soar at up to five times the speed of sound. The jet will be faster than a bullet, which generally travels at Mach 2, or twice the speed of sound. The new hypersonic vehicle, which could take flight by 2023, builds upon research from a 2013...

New antenna to make spaceship landing safer

New York, June 21 (IANS) There's a new way now to maintain communication with spacecraft -- sometimes lost for several moments -- as they re-enter the atmosphere. The key lies in tweaking with the antenna, the researchers said. Even routine communication blackouts with a returning spacecraft can create moments of anxiety as there is no way to know or control the location and stat...

NASA to build eco-friendly, supersonic jets

New York, June 8 (IANS) The US space agency NASA said it is spending over $6 million to fund research into cheaper and greener supersonic travel, reported Quartz. While modern fighter jets can fly faster than the speed of sound, the environmental impact is relatively small as not many fighter jets are in operation at a given time. However, the impact on environment would be massi...

Weather plays killjoy for NASA's flying saucer launch

Washington, June 6 (IANS) First high waves in the Pacific Ocean and now ill winds are playing spoilsport for the launch of NASA's flying saucer from a test range in Hawaii. NASA had to postpone the balloon-borne launch of its rocket-powered craft from a test range in Hawaii repeatedly due to weather concerns, NBCNews.com reported. The saucer-shaped Low Density Supersonic Decelera...

In a first, Hawking radiation mimicked in lab settings

London, Oct 14 (IANS) Scientists have created a lab-scale imitation of a black hole that emits Hawking radiation - the particles predicted to escape black holes due to quantum mechanical effects. Such objects could one day help resolve the so-called 'black hole information paradox' - the question of whether information that falls into a black hole disappears forever, a report in the jour...

Scientists reveal weather map, trace water on exoplanet

Washington, Oct 10 (IANS) Using the NASA Hubble Space Telescope, a team of scientists including an Indian-origin researcher has made the most detailed map ever of the temperature of an exoplanet's atmosphere and traced the amount of water it contains. The planet targeted for both the investigations was the hot-Jupiter exoplanet WASP-43b. WASP-43b is a planet the size of Jupiter b...

Friction and fractures inter-related, may explain earthquakes

London, July 9 (IANS) In a major breakthrough that has implications for describing the mechanics that drive earthquakes, researchers have discovered that how things break (fracture) and how things slide (friction) are closely inter-related. The findings overturning conventional wisdom stretching all the way to Leonardo da Vinci. Over 500-years-ago, da Vinci described how rough blocks...

Supersonic air travel to make a comeback?

Washington, June 19 (IANS) Supersonic passenger travel may soon make a comeback thanks to NASA's efforts to define a new standard for low sonic booms. Sufficient research has been done into developing a low-boom standard for the civil aviation industry, NASA said in a statement. Lessening sonic booms - shock waves caused by an aircraft flying faster than the speed of sound - is the m...
