Mobile radio passive radar makes harbors safer

Mon, 12/15/2014 - 7:44am
Many coastal areas and harbors go almost unprotected against acts of terror. Soon a new sensor system relying on signal echoes from cell towers can quickly detect even the smallest of attack boats. This mobile radio passive radar can also help airplanes avoid colliding with wind turbines.

Wind farms to do not affect property values, study finds

Mon, 12/08/2014 - 1:56pm
Wind turbine developments have no effect on property values of nearby homes and farms, according to new Canadian research. Researchers analyzed more than 7,000 home and farm sales in Melancthon Township and 10 surrounding townships in Dufferin, Grey, Simcoe and Wellington counties. Melancthon, located about 100 kilometres northwest of Toronto, is home to one of Ontario's first and largest wind farms; 133 wind turbines were erected between 2005 and 2008.

Smart anti-icing system for rotor blades

Wed, 12/03/2014 - 7:38am
In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient heating system frees these turbines from the ice in a matter of seconds. It is only switched on when water freezes.

Matched 'hybrid' systems may hold key to wider use of renewable energy

Wed, 11/26/2014 - 1:42pm
The use of renewable energy in the United States could take a significant leap forward with improved storage technologies or more efforts to 'match' different forms of alternative energy systems that provide an overall more steady flow of electricity, researchers say in a new report.

Horse racing position cuts drag up to 66 per cent

Researchers have revealed precisely how much different slipstreaming tactics reduce drag on a horse during a race.  

Bringing offshore wind energy on shore to power industry, homes and businesses

Tue, 10/28/2014 - 7:38pm
Feeding the world’s energy appetite may take innovative approaches in the future. A new book examines methods to bring offshore wind energy on shore to power industry, homes and businesses.

Impact of offshore wind farms on marine species

Thu, 10/16/2014 - 10:36am
Offshore wind power is a valuable source of renewable energy that can help reduce carbon emissions. Technological advances are allowing higher capacity turbines to be installed in deeper water, but there is still much unknown about the effects on the environment. Scientists have now reviewed the potential impacts of offshore wind developments on marine species and make recommendations for future monitoring and assessment as interest in offshore wind energy grows around the world.

Balancing renewable energy costs and optimizing energy mix

Mon, 10/13/2014 - 7:04am
Increasing reliance on renewable energies is the way to achieve greater carbon dioxide emission sustainability and energy independence. As such energies are yet only available intermittently and energy cannot be stored easily, most countries aim to combine several energy sources. Scientists have now come up with an open source simulation method to calculate the actual cost of relying on a combination of electricity sources.

American-made wind turbine blades

Wed, 09/17/2014 - 3:29pm
New research is helping makers of wind turbine blades improve the labor productivity associated with blade fabrication and finishing. This improved productivity makes US blades more cost competitive with blades from countries that pay workers lower wages.

Ahoy, offshore wind: Advanced buoys bring vital data to untapped energy resource

Fri, 09/12/2014 - 11:48am
Two large buoys that are decked out with advanced scientific instruments will help more accurately predict offshore wind’s power-producing potential.
