Oneka’s patent pending has been accepted by the International Patent Cooperation Treaty (PCT). The 21 claims were approved. The main innovation is the simplicity with the system that converts the fluctuating energy of the waves to a constant flow and pressure adapted for the reverse osmosis membranes. These membranes are very sensitive to these fluctuations. Only a few moving components constitute the system with no electrical components for its functioning. This is crucial as it is a marine environment.
