Strawscraper concept calls for a wind energy-harvesting toupee

Despite being the most common renewable energy technologies, solar panels and wind turbines still have their shortcomings. Particularly when it comes to the urban environment. Lack of space and concerns about noise are just two problems with integrating them into city settings in an unobtrusive way. That's why Belatchew Arkitekter wants to try a different approach with its Strawscraper concept, which proposes transforming the Söder Torn building in Stockholm into an urban wind farm by covering it in piezoelectric fibers.

UGE replaces 4K wind turbine with mysterious mid-range VisionAIR

Urban Green Energy (UGE) recently unveiled its newest vertical-axis wind turbine, the VisionAIR, as part of an installation at the Beijing International Garden Expo. The company confirmed to Gizmag that the VisionAIR is replacing its former 4K turbine, last seen adorning the top of an EV charging station, as its standard mid-sized option for customers. Compared with the previous model, the new turbine's design aims for better efficiency at moderate wind speeds, which UGE plans to integrate with its hybrid energy projects. Read More

Invelox wind turbine claims 600% advantage in energy output

SheerWind, a wind power company from Minnesota, USA, has announced the results of tests it has carried out with its new Invelox wind power generation technology. The company says that during tests its turbine could generate six times more energy than the amount produced by traditional turbines mounted on towers. Besides, the costs of producing wind energy with Invelox are lower, delivering electricity with prices that can compete with natural gas and hydropower. Read More

Concrete spheres could deliver feasible energy storage for offshore wind turbines

The intermittent nature of wind and solar power generation is one of the biggest challenges facing these renewable energy sources. But this isn’t likely to remain a problem for much longer with everything from flywheels to liquid air systems being developed to provide a cheaper form of energy storage than batteries for times when the wind is blowing or the sun isn’t shining. A new concept out of MIT can now be added to the the list of potential solutions. Aimed specifically at offshore wind turbines, the concept would see energy stored in huge concrete spheres that would sit on the seafloor and also function as anchors for the turbines. Read More

PowerWINDows aims to rethink the wind turbine

Wind farms may be hitting the big time, but that hasn't deterred inventors and technologists from tinkering, or even reinventing, the turbine itself. In the past few months we've seen wind energy systems that use discs attached to hydraulics and even charged water droplets, but how about skyscrapers outfitted with rotating window panels? This is the idea behind the University of Wollongong's PowerWINDows concept, a modular wind turbine designed to have less of an impact on the surrounding environment. Read More

World's largest wind farm, London Array, brought fully online

Phase one of the London Array usurped the UK's Greater Gabbard to become the largest operational offshore wind farm in the world when its final turbine (its 175th) was commissioned on Saturday afternoon. Though construction was completed back in December, it is only now that all of the farm's turbines are supplying the UK's national grid with electrical power. The array has a total capacity of 630 MW. Read More

EWICON bladeless wind turbine generates electricity using charged water droplets

Wind energy may be one of the more sustainable sources of power available, but the spinning blades of conventional wind turbines require regular maintenance and have attracted criticism from bird lovers. That might explain why we've seen wind turbine prototypes that enclose the blades in a chamber or replace them entirely with a disc-like system. But researchers in the Netherlands set out to eliminate the need for a mechanical component entirely and created the EWICON, a bladeless wind turbine with no moving parts that produces electricity using charged water droplets.

Japanese bank to fund first U.S. offshore wind farm

Not having a section devoted to cures for insomnia, Gizmag tends to pass over press releases about investment agreements. Tuesday's announcement that the Bank of Tokyo-Mitsubishi UFJ (BTMU) is to find somewhere in the order of US$ 2 billion for the Cape Wind is extremely interesting, however, as it means the U.S. should finally build its first offshore wind farm, with construction slated to commence before the year's end.

Analysts say renewable energy now cheaper option than new fossil fuels in Australia

In 2008, the Garnaut Climate Change Review ranked Australia as the highest per capita emitter of greenhouse gases of any OECD country and amongst the highest in the world. One of the reasons for the country's high carbon footprint is its reliance on coal for electricity generation – 54 percent of it, according to the Australian Coal Association. But a new study by Bloomberg New Energy Finance (BNEF) points to a cleaner energy future with the claim that unsubsidized renewable energy is now a cheaper option for electricity generation than new coal- or gas-fired power stations.
