ABSTRACT:
The portable and autonomous desalination system is an autonomous reverse osmosis (RO) desalination system utilizing power from a combination of electricity generation and storage sources that include a photovoltaic (PV) unit, a vertical-axis wind turbine (VAWT) unit, and an electricity storage unit. Electric power from PV, VAWT or storage units or a combination of these units is provided, depending upon the availability of sunlight or wind, or for night operation for water desalination using the reverse-osmosis process. The unit is portable, environmentally friendly, self-sufficient and self-sustaining in terms of supplying the electricity and fresh drinking water needs of the typical household. Multiple PV-VAWT-RO desalination units are combined together to provide fresh, clean water and electricity for communities of various sizes. A small-size, straight-bladed vertical axis wind turbine runs at very low wind speeds for urban operation.
