Tidal power from propeller and wind turbine techonology
A Welsh renewable energy company has teamed up with ship propulsion experts to design a new marine turbine which is far more robust.DeltaStream's propellers work in reverse to a ship's propulsion system – the water turns the blades to generate electricity .The device also has a fail-safe feature when the water currents become too powerful and threaten to destroy the turbines by dragging them across the sea floor – the propellers automatically tilt their orientation to shed the extra energy.

Windenergy 2008
One of the largest single object displays at Husum WindEnergy 2008 was a ‘mock-up’ nacelle from REpower’s latest 3.3 MW geared 3.XM onshore turbine.GE Drivetrain Technologies, a division of GE Transportation, is a North American supplier of megawatt-class wind turbine gearboxes. During the past few years the Drivetrain Technologies division has designed and developed a new gearbox for GE Energy’s popular 1.5 MW series.GE Drivetrain Technologies engineers also put a lot of effort in IntegraDrive serviceability.
