World’s first floating wind farm to be built off Scottish coast

In a deal between the Scottish government and Norwegian oil company Statoil, five wind turbines with a capacity of six megawatts each will be set on floating structures some 15 miles (25 km) off the northeast coast of Scotland near Peterhead. The Hywind pilot park, as it's named, is claimed to be the first floating wind farm in the world, and will generate enough power for 20,000 homes with operations expected to start in late 2017.Read More

Vortex bladeless turbines wobble to generate energy

Looking somewhat like a giant reed gently swaying in the wind, the new Vortex bladeless wind-driven generator prototype produces electricity with very few moving parts, on a very small footprint, and in almost complete silence. Designed to reduce the visual and aural impact of traditional spinning-blade turbines, this new device takes advantage of the power contained in swirling vortices of air.Read More

Superconducting coil to slash costs and improve efficiency of direct-drive wind turbines

Conventional offshore wind turbines are expensive and complicated pieces of machinery – in a large part because of their complex and maintenance-intensive gearboxes. Dr Shahriar Hossain from the University of Wollongong in Australia is looking to slash production costs and drastically improve efficiency replacing these gearboxes with a superconducting coil.Read More

De-icing system targets wind farm efficiency in cold climates

Given that the sterotypical image of the world's northern regions involves howling winds, why don't we see more wind turbines in such places? Well, it's largely because those turbines' blades would ice up a lot. The added weight could cause them to turn more slowly, to break down by throwing off their balance, and it could cause their operators to shut them down during potentially icy weather. The European Union Windheat Project is aiming to change that, with a carbon nanotube-based de-icing system. Read More

Artificial Wind Tree provides a fig leaf for unsightly turbines

Generally speaking, the peculiar appearance of wind turbines coupled with the fact they perform better when up high and out in the open sees them banished to uninhabited countryside, or even out to sea. But a French entrepreneur believes that sculpting them in the form of an artificial tree could lead to wider adoption in urban centers, making use of low winds that circulate around buildings and streets.
