Bats worth billions to agriculture

— 2 Apr 2011 11:16 | Environment

Pest-control services provided by insect-eating bats in the United States likely save the U.S. agricultural industry at least $3 billion a year, and yet insectivorous bats are among…

Supercritical carbon dioxide Brayton Cycle turbines promise giant leap

— 5 Mar 2011 13:09 | Technology

Sandia National Laboratories researchers are moving into the demonstration phase of a novel gas turbine system for power generation, with the promise that thermal-to-electric conversion…

Higher energy yield with torque vectoring gears

— 24 Feb 2011 20:44 | Technology

Most large wind turbines currently operate at variable speeds. When the wind is strong, the rotor turns fast; when it slows down, the rotor speed drops. Typically rotors complete 12…

The world can be powered by alternative energy, using today's technology, in 20-40 years

— 26 Jan 2011 19:07 | Technology

If someone told you there was a way you could save 2.5 million to 3 million lives a year and simultaneously halt global warming, reduce air and water pollution and develop secure, reliable…

Researchers discover how to tame hammering droplets

— 22 Jan 2011 10:05 | Technology

A water hammer can occur when a valve is suddenly opened or closed in a pipe carrying water or steam, causing a pressure wave to travel down the pipe with enough force that it can sometimes…

Syracuse University researchers contribute new ideas to enhance efficiency of wind turbines

— 3 Jan 2011 18:38 | Technology

One issue confronting the efficiency of wind as a promising renewable energy source is the wind itself - specifically, its changeability. While the aerodynamic performance of a wind…

Wind turbines may benefit crops

— 18 Dec 2010 13:42 | Environment

Wind turbines in Midwestern farm fields may be doing more than churning out electricity. The giant turbine blades that generate renewable energy might also help corn and soybean crops…

Calculating tidal energy turbines' effects on sediments and fish

— 13 Dec 2010 17:01 | Environment

The emerging tidal-energy industry is spawning another in its shadow: tidal-energy monitoring. Little is known about tidal turbines' environmental effects and environmentalists, regulators…

Whale-inspired ocean turbine blades

— 28 Nov 2010 14:05 | Technology

Interest in developing alternative energy sources is driving the consideration of a promising technology that uses underwater turbines to convert ocean tidal flow energy into electricity…

Optimising large wind farms

— 24 Nov 2010 22:18 | Technology

Wind farms around the world are large and getting larger. Arranging thousands of wind turbines across many miles of land requires new tools that can balance cost and efficiency to provide…
