Cross-flow turbines, also known as vertical-axis turbines, are attractive for power generation from wind and water currents. Some cross-flow turbine designs optimize unsteady fluid forces and ...

Underwater tidal turbines are gaining recognition as a viable renewable energy source, with energy companies and governments ...

These “cross-flow” turbines can harvest energy from ... While similar real-world tests of tidal energy turbines are still a way off, the team at the Pacific Marine Energy Center are working ...

That said, tidal turbine rotors bear little resemblance to their cousins ... ADAG's systems, however, feature a vertical-axis (cross-flow) design, in which the blades and rotor transmission shaft are ...

which is equipped with devices to measure turbine speed, tidal flow rate, voltage and electrical current. A bigger test came in April, when the barge was towed to the Western Passage between ...

Tidal stream technology, which includes axial and cross-flow turbines, is another promising area. Tidal farms in shallow, transitional, and deep waters are being developed to increase marine ...

Major disadvantages of tidal energy, though, are a scarcity of available ocean sources that have high flow velocity or high tidal ranges. Tidal currents, with sufficient energy, could be used in ...

Now, in a seemingly obvious move, researchers have found that that same principle can be applied to underwater turbine blades to more efficiently convert low velocity ocean tidal flow energy into ...

(CBC) One of the companies behind a large experimental tidal ... flow of every freshwater river in the world. The estimated potential of the Fundy region alone is upwards of 60,000 megawatts of ...

ORPC is now testing its tidal turbine at the Strangford Lough Tidal Test Site in Northern Ireland. The trial is part of the X-Flow project, where Queen's University Belfast (QUB) and Applied ...

Unhelpfully, it does not disclose the key “strike price” for energy that the government would need to underwrite for the scheme to go ahead. Without agreement on this, developer Tidal Lagoon ...
