SALINE water conversion; WATER purification; REVERSE osmosis (Water purification); FOSSIL fuels; SEPARATION (Technology)

The article focuses on new generation of technology uses heat from the sun to provide clean, salt-free water and removing salt and contaminants from the oceans and groundwater is one way to slake humanity's thirst. It mentions plant use reverse osmosis, which forces seawater through salt-blocking membranes and facilities are typically powered by carbon-emitting fossil fuels. It also mentions plant with giant mirrors that concentrate sunlight and superheat water.
