Turbine

When a wind turbine reaches the end of its working life, some components can be recycled but blades often end up in landfill. Vestas is looking to commercialize a new chemical process that can break down all epoxy-based turbine blades for reuse.

Early last month, Siemens Gamesa reported that recyclable turbine blades had been successfully installed at the Kaskasi offshore wind farm in the North Sea. Now the company has announced the market availability of an onshore equivalent.

Solar chargers are one means of keeping a smartphone charged when in remote locations, but they're dependant on hours of daylight and sunlight intensity. Portable turbines are an alternative and product designer Nils Ferber has created one he says is more portable and effective than any other.

Migrating salmon in the Pacific Northwest are set to be helped on their journey by Sensor Fish. Developed by PNNL, these devices record and analyze the physical stressors faced by the fish on their trek and provide hydroelectric dams with data to become more fish-friendly.

The CSIRO has claimed a world record for the highest temperatures ever recorded using solar energy to generate "supercritical" steam at its solar thermal test plant in Newcastle, Australia. This achievement is touted as a breakthrough for solar energy production.

A helium-filled shell with a wind turbine in the middle, the Buoyant Air Turbine from Altaeros has already been tested to 500 feet off the ground in 45 mph winds. Now it's set to break the world record for the highest wind turbine in history.

Wind-watcher Mike Barnard explains why innovative wind technologies are rarely if ever a match for plain old three-blade turbines.

India is the latest country to wade into the tidal power waters with the announcement of its first commercial scale tidal current power plant to be constructed in the Indian State of Gujarat.

Researchers have found that the bumpy protrusions, known as tubercles, on the leading edge of humpback whale flippers can be applied to underwater turbine blades to more efficiently convert low velocity ocean tidal flow energy into electricity.

Atlantis Resources Corporation has just unveiled its recently completed AK1000 tidal turbine before it heads off to Orkney in Scotland for installation and connection to the grid

Researchers are developing controllable rubber trailing edge flaps for wind turbine blades, that could make them quieter and more efficient.

The world’s biggest wind turbine that will stand 162 meters (533 feet) tall, generate 10-megawatts and feature a rotor diameter of 145 meters (475 feet will be constructed in Norway.
