Drakoo
The working principle of Drakoo, being a twin-chamber oscillating water column system, is to transform waves into a continuous water flow which drives a hydro turbine generator. First: an incoming wave increases the inlet chambers’ water level, while simultaneously water is partly directed from the inlet to the outlet chamber, through the hydro turbine. Second: once the water level outside the device falls, both chambers’ water levels also fall, leading to a flow from the inlet to the outlet chamber and the outlet chamber to the outside environment. The two-step action of the water columns occur continuously in waves. Meanwhile, the checkerboard valves regular the water flow. The water flow is nearly constant and one-directional resulting in smooth rotation of the hydro turbine which in turn generates stable electricity efficiently.
