Wind turbine

A new 3D-printed composite surpasses the lightness and stiffness of balsa wood (Photo: Har...

Reseachers at Harvard University have developed a way to 3D-print a cellular composite with record lightness and stiffness using an epoxy resin. This marks the first time that epoxy is used for 3D-printing, and the advance could lead to the development of new lightweight architectures for more efficient wind turbines, faster cars, and lighter airplanes.  Read More

Solar Wind Energy's Downdraft Tower generates its own wind that is directed down the hollo...

When we think of wind power, we generally think of huge wind turbines sitting high atop towers where they can take advantage of the higher wind speeds. But Maryland-based Solar Wind Energy, Inc. is looking to turn wind power on its head with the Solar Wind Downdraft Tower, which places turbines at the base of a tower and generates its own wind to turn them.  Read More

The Liam F1 Urban Wind Turbine is said to be considerably more efficient than most convent...

Although it's getting increasingly common to see solar panels on the roofs of homes, household wind turbines are still a fairly rare sight. If Rotterdam-based tech firm The Archimedes has its way, however, that will soon change. Today the company officially introduced its Liam F1 Urban Wind Turbine, which is said to have an energy yield that is "80 percent of the maximum that is theoretically feasible." That's quite the assertion, given that most conventional wind turbines average around 25 to 50 percent.  Read More

GE has found a way to extend wind turbine rotor blades without replacing them

Sometimes progress can be its own worst enemy, with early adopters being stuck with obsolete equipment that leaves them with the choice of living with out-dated technology or an expensive replacement. The green energy field isn’t immune to this, and as part of a US$2 million renewable energy project, GE has developed a way to make smaller, less efficient wind turbines into bigger more efficient ones with a bit of plastic (or carbon composite) surgery.  Read More

Seatower: bringing down the cost of offshore wind farming

Offshore wind farming combines the clean, green, environmentally neutral benefits of land-based wind turbines, while being a lot less visually intrusive ... and restricting the usual NIMBY opposition to crustaceans and invertebrates. It's currently a lot more expensive to install turbines out at sea, though, and that's restricting the sector's development. Which is why the Seatower Cranefree turbine platform could be such a significant step forward. Cheaper and easier to install, and requiring less gargantuan and specialized equipment than standard monopile foundations, the Seatower base could help offshore wind farms reach profitability a lot quicker.  Read More

The Windpax wind turbine system can be set up in less than two minutes and mounted on a nu...

Keeping mobile electronic devices powered up can be difficult for the modern camper and hiker. Generating power from Mother Nature in the form of wind and sun is the preferred option for many, with a number of portable solar and wind generators emerging to fill this need. The latest is Windpax, a collapsible, portable wind turbine system designed to not take up too much space in a backpack.  Read More

A top view of the Trinity

There are already plenty of solar-powered phone chargers out there, but they won't do you much good at night, when it's cloudy, or even if you live too far north. Chances are, however, that in any one of those situations, there will be at least a slight breeze ... and that's where the Trinity portable wind turbine comes into play.  Read More

Festo has applied the same methodology used in its robotic SmartBird to harvest energy fro...

Back in 2011, Festo created a natural-flight mimicking bionic seagull with flapping wings dubbed SmartBird. The company is now looking to apply similar principles in order to convert wind power into electricity with its DualWingGenerator system.  Read More

The Parasol system uses passive radar sensors and mathematical algorithms to determine if ...

With aspirations to claim 80 percent of its power from renewable sources by the 2050, it follows that Germany is taking a proactive approach to its clean energy transformation. Wind farms, while set to play an important part in achieving this goal, often meet impassioned opposition from disgruntled neighbors piqued by their perpetually blinking beacons. In an effort to address this issue, researchers have developed a sensor system for wind turbines which detects nearby aircraft, switching on a beacon warning system only as they approach.  Read More

Expedition users can switch between the turbine, solar and hand crank power

Powertraveller adds an ultra-versatile portable charger to its gadget charger line. Not only does the new Powermonkey Expedition include standards like a clamshell solar panel, AC adapter and crank charger, it complements them with a portable wind/river turbine. Carry the kit on your adventures and simply connect the generator component that's most suitable for the current conditions.  Read More
