Owl Wing Design Could Make Wind Turbines Quieter

Written by , on June 16, 2015

Conservationists are concerned about the effects of the noise of wind turbines on wildlife and some people who live near turbines complain about their noise. Researchers led by Nigel Peake at the University of Cambridge have turned to owls for ideas about how to reduce the noise. Owls are famously silent predators, able to surprise […]  Read more »

Cheaper, Silent, Bladeless Wind Turbines

Written by , on May 17, 2015

In 1940, the newly built Tacoma Narrows Bridge began to vibrate violently and soon collapsed in windy conditions. Ever since, engineers have focused on ways of stopping their structures vibrating in this way. Now, a group of Spanish engineers is working to harness the energy potential of vibrating structures. Instead of using the wind to […]  Read more »

Passive Computer Cooling System Could Save Billions

Written by , on May 1, 2015

Engineers at the University of Alabama are testing a passive cooling system for computer processors that they believe could save U.S. consumers more than $6.3 billion a year in energy costs associated with running their computer cooling fans.  Read more »

Fueling Vehicles with Hydrogen from Corn Waste

Written by , on April 8, 2015

Researchers have found a way to make hydrogen fuel by a biological method that uses cheap and abundantly available corn stover (the stalks, cobs and husks) and greatly reduces the time it takes to produce the fuel.  Read more »

Airborne Turbine for Remote Sites

Written by , on October 2, 2014

Winds 300 to 600 metres above the ground are, on average 5 to 8 times as strong as those at the surface.

Altaeros, a four-year-old company in Massachusetts, has developed its Buoyant Airborne Turbine (BAT) to take advantage of these stronger, more consistent winds.  Read more »
