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

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

A newly opened wind farm on the roof of the Oklahoma Medical Research Foundation is claimed by turbine suppliers Venger to be the largest building-integrated wind farm in the US. But might it be the largest in the world?  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

B9 Shipping's sailing cargo ships would feature a Dyna-rig sail system

Ireland-based B9 Shipping has started work on a full-scale demonstration vessel as part of its goal to design the modern world’s first 100 percent fossil fuel-free cargo sailing ships. Unlike most conventional large cargo vessels, which are powered by bunker fuel, B9 Shipping’s cargo ship would employ a Dyna-rig sail propulsion system combined with an off-the-shelf Rolls-Royce engine powered by liquid biomethane derived from municipal waste.  Read More

There’s wind in that thar sky ... That’s the sort of thing that – conceivably – might be wistfully said by someone who is tasked with looking for locations in which to locate wind turbines. Their job could soon be getting a little easier, however, thanks to a new balloon-based wind-prospecting system.  Read More

Depiction of a cargo ship equipped with the Wind Challenger Project system of sails

Of the world's nearly 45,000 cargo ships, many burn a low-grade bunker fuel in their engines and produce pollution equivalent to millions of automobiles. To help reduce that toxic load and keep the price of shipping freight reasonable, engineers at the University of Tokyo (UT) and a group of collaborators have designed a system of large, retractable sails measuring 64 feet (20 m) wide by 164 feet (50 m) high, which studies indicate can reduce annual fuel use on ships equipped with them by up to 30%.  Read More

Remember the Airborne Wind Turbine covered by Gizmag towards the end of March? The creator of the prototype, Altaeros Energies, has been in touch to show us a video of the prototype in operation and we can confirm that a) it flies and b) the turbine goes round.  Read More
