Aerospace engineers are developing dual-rotor technology to improve the energy harvest of wind turbines. The idea to look for better performance by adding a second rotor to wind turbines came from a previous study. The researchers used wind tunnel tests to see how hills, valleys and the placement of turbines affected the productivity of onshore wind farms.
Researchers have borrowed from biological structures called tubercles that humpback whales use to maneuver in the ocean to make a piezoelectric energy harvester for use as an airflow or fluid speed and direction-sensing device.
To make ships more eco-efficient, engineers have been working with alternative fuels. A Norwegian engineer is currently pursuing a new approach: With VindskipTM, he has designed a cargo ship that is powered by wind and gas. Software will ensure an optimum use of the available wind energy at any time.
Numerous bats are killed by German wind turbines. The number of such turbines, already very high, is planned to be increased further. More than two-thirds of bats being killed by wind turbines on German ground are migrants on their way between summer and winter habitats. Due to its geographical location in Europe, Germany has consequently a central responsibility for the conservation of migratory bats.
Researchers are demonstrating that it is possible for a redundant fishing vessel to be used as a power plant. The first vessel of its kind is now anchored offshore in the Stadthavet area west in Norway, with the aim of generating electricity from the natural forces of the sea.
A new study demonstrates that an energy system based completely on renewable forms of energy will be economically viable in the future. Within ten years, solar and wind power will be the cheapest forms of energy production for Asia's largest energy markets.
The disruptiveness of the noise generated by wind power plants in Finland is the focus of a new study that combines the measurement of the noise produced by wind power with the noise experienced by humans in relation to sound pressure levels and the time and frequency behavior of sound.
Scientists have developed the first autonomous industrialized public lighting system that works with solar and wind energy.
A new analysis suggests that large-scale wave energy systems developed in the Pacific Northwest should be comparatively steady, dependable and able to be integrated into the overall energy grid at lower costs than some other forms of alternative energy, including wind power.
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 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.
