20kW Container Type New Oscillating-Water-Column (OWC) Wave Energy Converter (Water push air, Air push water, and then the hydro turbine)
The new design has a U-shape water column, one side of the U-column is open to the atmosphere and the other side connected to the ocean. A generator is placed in the middle of the U-shape water column to generates electricity when water swing back and forth due to the air pressure changes from the wave motion.
