Wind turbine

Helical Robotics' HR-MP20 wind turbine-inspecting robot

Currently, wind turbines are inspected for damage in two main ways: someone stands on the ground below them and uses a telescope, or people use rigging systems to actually climb across them. Now, Oregon, Wisconsin-based Helical Robotics is offering an alternative – camera-equipped turbine-climbing robots.  Read More

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 has revealed plans to build what it believes will be the first net zero retail 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

North Carolina 4th-grade students have raised enough funds on Kickstarter to allow their c...

After looking into the pros and cons of nine methods of electricity production (including coal, geothermal, biomass, and solar), a group of 9 and 10 year-olds from Central Park School for Children in Durham, North Carolina decided that their classroom should be powered using only energy from the sun. They hit Kickstarter at the beginning of this month with a modest funding goal of just US$800 to help finance the installation of a small PV panel array – a target that was smashed in less than a day.  Read More

Blade Dynamics already manufacturers impressive wind turbine blades

The Energy Technologies Institute in the United Kingdom has announced that UK-based wind turbine blade manufacturer Blade Dynamics has been awarded a contract that will see the creation of the world's longest turbine blades, between 80 and 100 meters (262 and 328 feet) in length. Currently, the longest turbine blades are for offshore wind farms, maxing out at 75 meters (246 feet).  Read More

The LM-6 prototype AVE system

Tornadoes generally evoke the destructive force of nature at its most awesome. However, what if all that power could be harnessed to produce cheaper and more efficient electricity? This is just what Canadian engineer Louis Michaud proposes to achieve, with an invention dubbed the “Atmospheric Vortex Engine” (or AVE).  Read More

GE's fabric-covered blade is reminiscent of the fabric-covered wings used on World War I f...

In a bid to help shape the inexorable march toward more efficient wind power, General Electric Power and Water is developing a new fabric-covered wind turbine blade which promises to cut the cost of wind turbine manufacture significantly, while also allowing a larger blade size, and facilitating easier transportation.  Read More

Unlike conventional air traffic control radar systems, the Holographic Radar system can re...

Wind farms and airports don’t mix. Unfortunately, when the blades are turning on wind turbines, the motion can interpreted as aircraft on air traffic control radar screens. Needless to say, the results of such confusion could potentially be catastrophic – or at the very least, they could make things much more stressful for already-frazzled air traffic controllers. UK tech firm Aveillant, however, claims that its Holographic Radar system is the solution to the problem.  Read More

The prototype TimberTower constructed in Hannover, Germany

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

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
