Wind turbine

Canadian startup Harvistor has tested its DARWIND5 vertical axis wind turbine and says it ...

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.  Read More

In an average wind speed of 12 mph (20 km/h), the PPC is said to produce 12 kW of power

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

Vestas has upped the capacity of ts V164 wind turbine to 8 MW

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

Military veteran Raymond Green created the Catching Wind Power prototype at an estimated c...

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.  Read More

New York's Urban Green Energy has installed the world's first fully integrated wind-powere...

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.  Read More

A Siemens B75 blade in its mold

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

When it comes to large-scale applications, vertical axis wind turbines are traditionally c...

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

The turbine is particularly well-suited to the gusting winds of inner cities

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

The system developed at Langley flies a kite in a figure-8 pattern to power a generator on...

Currently, land-based tower wind turbines are the dominant source of wind power, but they take up a lot of space and generally need to be placed in high visibility areas, such as the tops of hills or ridges. They are also located close to the ground, where friction from the Earth’s surface slows the wind and increases its turbulence, negatively affecting the efficiency of the turbines. NASA engineers are looking at technologies that would help airborne wind power systems, capable of generating much more power, get off the ground.  Read More

The Flow vertical turbine concept features bamboo blades with an LED at each tip to provid...

Grid-powered street lighting is something that many of us take for granted, but there are parts of the world where electricity is a scarce resource and when the sun goes down, local pedestrian traffic in areas where public lighting is not abundant can all-but cease due to safety concerns. In searching for an inexpensive off-grid solution for places like the Colombian city of Cartagena, designer Alberto Vasquez looked to the wind for help. His Flow concept makes use of readily-available bamboo for the construction of a vertical wind turbine in a similar vein to the Power Flowers concept, but with LED light modules at the end of each blade. As the wind catches the blades, the LEDs light up the walkway beneath.  Read More
