Coastal Defence Integrating Wave-Energy-Based Desalination: A Case Study in Madagascar
In arid, coastal cities, water demand is often met through large-scale desalination systems. However, the energy required to run desalination plants remains a drawback. Further, numerous low-density population areas lack not only fresh water availability, but in most of the cases electrical grid con...
