The Saphonian bladeless wind turbine draws inspiration from the design of a ship's sails

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.  Read More

The 100 percent biofuel-powered Falcon 20 being tailed by the data-collecting T-33

Earlier this year, Air Canada joined a growing number of airlines conducting flights using biofuels. Like similar flights by Boeing and Lufthansa, the aircraft was powered by a mix of petroleum and biofuel. Now the National Research Council of Canada (NRC) has removed the fossil fuel component completely with the first flight of a civil jet powered by 100 percent unblended biofuel.  Read More

Amonix solar panels break through the 33-percent efficiency barrier

Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded "one third of a sun" in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent.  Read More

Despite offering numerous advantages over its rotating brethren, most notably the ability to reach the high-speed winds found at higher altitudes, kite-based energy systems are yet to really get off the ground in a meaningful way. But things are looking up. Earlier this year, NASA revealed it is investigating ways to improve the aerodynamics and autonomous flight control of kites for power generation applications, and now Berlin-based wind energy developer NTS GmbH has teamed with the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) to make their own kite energy system concept a reality.  Read More

Having successfully negotiated the challenging regulatory slopes of the U.S. Bureau of Land Management, the U.S. Forest Service, the U.S. Department of Energy, and a host of Oregon state agencies, the Newberry Enhanced Geothermal Systems (EGS) demonstration project is in the process of creating a new geothermal reservoir in central Oregon. The core of the new reservoir is a two mile (3.2 km) deep well drilled about four miles (6.3 km) from the center of Newberry Volcano. The rock surrounding the wellbore reaches temperatures in the order of 600° F (315° C), and is nearly impermeable to water. That, however, is about to change.  Read More

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

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

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

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

Revamping a concept that was first explored forty years ago, researchers at the University of Southern California (USC) are putting the final touches on a patent-pending design for cheap, rechargeable, high energy density iron-air batteries. Because of their unique features, the batteries look particularly well-suited to the kind of large-scale energy storage that could accelerate the adoption of renewable energy sources.  Read More
