Wind turbine

Getting a wind turbine to a decent height to allow it to reach stronger winds than those found closer to the ground generally means sitting them atop a tower. Despite the eco-credentials of wind turbines, these towers are usually constructed from steel, which is not only expensive, but requires large amounts of energy to process. In an effort to make wind turbines even greener, German company TimberTower has erected a wooden 1.5-MW wind turbine in Hannover, Germany. Read More
Tunisian green energy startup Saphon Energy has created a new bladeless wind turbine which draws inspiration from the design of a ship’s sails, and promises to convert the kinetic energy of the wind into electricity at up to double the efficiency – and half the cost – of a typical wind turbine.

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT). Designed by Harvistor, it comes with a promise of more oomph than existing models for small-scale wind power generation. According to the company, recent tests showed that its technology can achieve 35 percent more kilowatt hours per year than current VAWTs for the same sweep area, besides operating at 25 percent lower heights than similarly priced market leaders.

Wind turbines have the potential to be very useful in providing renewable power to remote communities which have little or no infrastructure. Unfortunately, larger turbines tend to require a relatively involved set-up, with specialist gear needed to construct and maintain the turbines. The Portable Power Center (PPC) by Uprise Energy innovates in this regard by providing a self-contained unit which folds within a shipping container, and can be transported by truck. Read More
Danish wind turbine specialist Vestas was already looking to claim the title of the world’s largest offshore wind turbine with its proposed V164 that boasts a diameter of 164 m (538 ft). The company claims the V164 was developed with the potential of increasing its turbine size and now it has done just that, upping the capacity from seven to eight megawatts. So not only is the V164 set to boast the largest swept area of any single wind turbine, it will also claim the title for the world’s largest capacity wind turbine. Read More
World War II veteran Raymond Green, an 89 year old resident of Jackson, California, has created a working prototype of a "bladeless" wind turbine which is bird and bat-friendly, and very quiet in operation. Though still in development at present, Green intends his design to be produced in various sizes, from smaller personal versions to much larger turbines which could be implemented in wind farms.

What's claimed to be the world's first fully integrated wind-powered electric vehicle charging station has just been unveiled in Barcelona, Spain. The Sanya Skypump marries a 4 kW turbine developed by New York's Urban Green Energy (UGE) and General Electric's (GE) WattStation charging technology to offer users the chance to juice up an EV using clean, renewable energy.

Siemens has released pictures of its truly gargantuan B75 wind turbine rotor blades. As you might imagine, the prototype turbines that will use these blades boast some staggering statistics of their own (Airbuses at the ready, please). Read More

Albuquerque-based Sandia National Laboratories is conducting comprehensive research into the viability of vertical axis wind turbines (VAWTs) for offshore use. The design, previously considered impractical for large-scale applications, has the potential to transform offshore wind technology, making it a more economically viable energy source. Read More

A new prototype wind turbine, 30 years in the making, and designed for flat-pack shipping and easy assembly, has been erected at Keele University in the UK. Read More
