Dodgy wind? Why "innovative" turbines are often anything but

Virtually every week there are articles about new and innovative methods for harvesting wind energy. And every week more megawatts of capacity from three-blade horizontal-axis wind turbines (HAWT) becomes operational, despite all of the contenders. Why aren't these innovative new products knocking the iconic HAWT off its perch? Is it possible to tell which are likely to be viable? These eight points are a useful way to assess which technology has potential, and which are likely just hot air.Read More

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

SKWID harnesses the power of both the wind and the tide

There are already a wide variety of renewable energy systems that harness the power of the wind, along with some that generate power via the flow of ocean currents. According to Japanese engineering firm MODEC (Mitsui Ocean Development & Engineering Co.), however, its soon-to-be-tested SKWID system will be the first one to do both.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

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.Read More

Walgreens plans to build first net zero retail store in the U.S.

Drugstore chain giant Walgreens has announced its intention to build what the company believes will be the first net zero retail store in the United States. Once open for business, engineers anticipate that the combination of solar panels, wind turbines, geothermal technology, energy-efficient building materials, LED lighting and ultra-high-efficiency refrigeration will allow the new store to produce energy equal to or greater than it consumes.Read More
