"Telescoping can" wave energy device beats test predictions by 20%

• arclein
This linear motion in this "telescoping can" compresses the air in the Waveswing device, creating an air spring to push the floater section back up as the wave rolls onward. As the floater moves up and down, it drives a hydraulic motor, which converts the linear motion into rotation, and a regular electrical generator draws power from both the upward and downward strokes.
